- Yamaha YST-M10 Speakers For Sale -

The M10's are very attractive speakers, which is what drew me to them originally. About nine inches tall, in a black/almond colouring, these speakers have a pretty cloth grill on the front, unlike the cheap, resonating plastic or metal grills of normal PC speakers. Each speaker has a distinctive curve outwards, with a finely moulded plastic backing.

Instead of some cheesy SuperBass function, controls are very simple: Power, Presence and Volume. Presence is basically Tone: more treble or bass in one knob. All the controls are on the right speaker, and the setup is integrated: no additional amplifiers are needed, just the supply and the two cabinets.

Yamaha YST-M10 Speaker Most importantly, the M10 supports both line level and headphone level input. There is an input for power, supplied with a "wall-wart" type power supply which unfortunately takes up an extra plug space. There's an output on the right speaker to power the left speaker along with a stereo input. The signal connectors are both 1/8" stereo mini-jacks. Click to enlarge the picture

My first test of the YST-M10 was to on my desktop computer which I still use! Turning the volume up high, the first brass horn blasts of a Stan Kenton big-band scared me! I've used these for speakers for a long time and the sound quality fills the entire room today as it did when first tried.

When I need volume, the M10 delivers! It has great range, and you can never hear the thing resonate. The disturbing thing is that the M10 is only rated at 10W. It uses Active Servo Technology, which, according to a more knowledgeable friend, basically improves the SPL and quality by actively monitoring the output and changing the speaker signal dynamically. It compares to 80W PC generic soundcard speakers.

Comes with a two (2) 1/8" mini stereo cables and 19V power supply. Just hook up and enjoy! Price was $50, now reduced to $30 payment to my Paypal account, shipping is extra.

Optimized Wideband Antenna - OWA

There's been some movement toward wideband antennas that cover the complete band with low SWR and have a direct 50 ohm feed. The strange part is the Hams that want this feature are mostly "niche" operators; they either favor SSB operation or are CW aficionados. They operate in one section of the band and really don't need the complete band coverage other than it sounds like they would like this . . . b/c the antenna has been optimized . . . here's what the "optimized" in OWA means.

The OWA explanation:
The Optimized Wideband Antenna (OWA) is antenna feed-point matching method developed by WA3FET that provides an increased feed point impedance while widening the VSWR bandwidth. The OWA is implemented in a yagi by moving the first director very close in front of the driven element. The only negative aspect of OWA yagis is that they give up a slight amount of forward gain (typically less than .5dB) from a conventional yagi. This small degradation is impossible to notice in operation and is well worth the simplicity of direct feed and the excellent bandwidth.

Analyzing the "OWA" method;
O = optimized . . . this word causes difficulties; optimized means only ONE parameter is "peaked", not all!
W = wideband . . . implies complete band operation. Nothing wrong with that;
A = antenna . . . dipole, yagi, quad, etc. No problem here.

So the use of the term "optimized" is a problem! What does "OWA" method actually accomplish . . by moving the director closer to the driven element, the feed-point impedance is raised which reduces the F/G and reduces the SWR thereby increasing the operating bandwidth. That, friends as stated, is a "method" or a "technique" and results state that this method will make an optimized wideband antenna. The problem is that the optimization process only peaks ONE parameter at the expense of the others.

The word "optimize" by definition means to make as perfect, effective, or functional as possible. Does performing the OWA method result in the best F/G and the best F/B and the best BW? The answer is NO! Performing this "method" results in a peaking of one parameter and compromise for the remaining parameters. This is far from the BEST, most favorable, ideal or perfect.

So the OWA method can't be the BEST for all parameters! If I happen to want more F/G, the OWA method will not provide that. So performing the "OWA" method does NOT result in the BEST that can be done. However, the authors use the term optimize which implies to the reader that the antenna is now the best it can be when actually, it is less than it was before!

Here's an example - - the HG204BA yagi features four (4) elements on a 26ft boom. The 'graphical' summary on the left shows what it does "out-of-the-box". Next to it on the right is the OWA technique to transform the yagi.

HG 4 el 20M
                              yagi Stock HG 4 el 20M
                              yagi w/ CWB Matching
The stock 204BA meets a lot of users needs; good F/G, good F/B ratio with reasonable SWR across the complete 20M band. Could that be called "the best"? If any version of this yagi could be called the best, this is it! There is absolutely NOTHING wrong w/ that yagi as is. For MOST Hams, this yagi provides the overall best in F/G, F/B and SWR that can be had for that boom length. And you certainly can operate over the full 20M band w/o any SWR problems!

By applying the OWA method/technique, the antenna is modified to loose some F/G while lowering the overall SWR (1.5:1 vs 1.2:1 is nothing to write home about). The main difference is that you can now use a direct 50 ohm coax feed. That is not necessarily an advantage b/c a balun is still required as it was before the OWA method. The only thing that has changed is the possible elimination of the "match" (hairpin for the HG204BA).

Is this yagi now "better" than stock HG204BA? I don't think so! Actually the yagi's specs have been degraded but now some can now call this an OWA. A change s/b made to the "name"* to better define what was done to modify the antenna and remove the ambiguity using the word "optimized". This removes the mis-understanding with most Hams who think the antenna is now the "best" it can be b/c it was "optimized"!!!

*   A more appropriate term is . . . . Comprehensive Wideband Matching - CWM . . this much better describes what's going on. You loose F/G for the sake of operating bandwidth by changing feed-point impedance as the result of moving the director closer to the driven element. The resulting antenna is not OPTIMIZED for all parameters.

Battery Replacement Note for VX-170
FBN-83 (1400ma) to FBN-94 (1800ma)

If you purchase a replacement battery for the VX-170 2M HT and choose the FBN-94 to replace the FBN-83, you need to cut off the plastic battery cover from the bottom right corner as shown so that the battery's ground shows (metal case). If you don't it won't CHARGE when you plug it into the standard charger via the "Ext DC" side input.

---- FTdx101D/MP 'ttbf' mode enable ----

Received email from Damon, KJ7E regarding the latest FW update: 202003 of 3/16/20. Here's what he wrote:
Been a long time, lots to talk about, but I picked up an FTDX101MP a few months ago and just figured out how to enable the TTBF for extended TX bandwidth. With the latest 202003 firmware update package you can enable the TTBF TX BPF option. Same as the FTDX5000, power on and press DNR+DNF buttons on the main RX side (lower set).

Did a real quick sweep between the two settings this morning, didn�t plot it but here are the results;

[Also received an email from Terry W6RU and he confirms the addition of the 'ttbf' mode by following the above instructions. Charles, W4CO has also reported that performing the FW update does indeed give the ttbf mode on his FTdx101MP.]

Update: Jun 22, 2014
= FTdx1200 & FTdx3000 4Khz SSB TX =
Over the past few days, I spent some time critically looking over the specs of the FTdx1200 and FTdx3000 and I'm now convinced that 4Khz SSB TX mode is possible in both radios! In other words, it's possible to place the FTdx1200 and FTdx3000 into the 'ttbf' mode thereby extending the SSB TX BW to 4Khz.

Two things show that this is possible:
1) The "WIDTH" control can be extended to 4Khz by turning it fully CW;
2) The specs for Menu #104 (for both radios) state that these TX BW are possible:
   [1-30= 100-3000]; [1-29= 100-2900]; [2-28= 200-2800]; [3-27= 300-2700]; [4-26= 400-2600] and 3000WB.

The last setting "3000WB" [100-3000] is found on the FT2000, FTdx5000, FTdx9000 radios; when the "magic" two buttons are pressed while pressing the POWER switch, "3000WB" is replaced in Menu #104 by "ttbf" which is the 4Khz TX mode. The two buttons for the FT2000 are described in the FT2000 table below.
Received an email tonight from VE3WCQ which stated . . .

" I thought I would let you be the second site to learn of the TTBF for the FTdx3000 and FTdx1200.

  1. Make sure power is off.
  2. Find the CS and TXW buttons just left of the Freq Dial.
  3. Push and hold "CS" and "TXW" buttons in while powering the radio via the "ON/OFF" switch.
  4. Select Menu# 104 and see that "TTBF" has replaced 3000WB.
  5. If you wish to go back to 3000WB just do steps 1 to 4.

Well that's it. I hope your followers will enjoy.    Mike VE3WCQ

Tnx Mike for the info . . many owners will have a big smile after tonight! Yaesu used a great choice of buttons; the "C.S" is direct MENU access-select while the "TXW" selects the SSB TX BW.

For EQ and processing selections visit my "4Khz SSB EQ" page here

For a "quickie" EQ, try these settings for the parametric EQ mode (#159 to #167) with a 'quality' mic plugged directly into the front panel connector;
----- Desc ----- Menu# -- Setting--
PrmEQ1Freq ----- 159 ---- 300
PrmEQ1Levl ----- 160 ---- -6
PrmEQ1BW ------ 161 ----- 1

PrmEQ2Freq ----- 162 ---- 700
PrmEQ2Levl ----- 163 ---- -5
PrmEQ2BW ------ 164 ----- 1

PrmEQ3Freq ----- 165 ---- 3200
PrmEQ3Levl ----- 166 ---- 10
PrmEQ3BW ------ 167 ----- 1

I've added the FTdx3000 to the "NO EQ" page here. OK, how about some other EQ entries?

The FTdx5000 SSB TX can attain 4Khz BW!!

The FTdx9000 and FT2000 can be programmed to a 4Khz SSB Tx BW, so should the FTdx5000. That's what I've always believed and sure enough, it can! NAIA was the first to discover this as I recall. It's easy to do and here's how to get the radio into the 4Khz SSB TX mode.

So how is it done? Access Menu #104 and look at all of the entries. One of them is labeled "1-30" and another "3000WB". "WB" stands for "Wide Band". As you read in the "How to EQ . . " section, both are identical. So the "dual" entry implies that the "WB" can be made to extend further. And it can!

How to
                            get TTBF mode on FT2000 How? Simply do the following;
Turn the radio ON while holding in DNF on the CENTER VFO-A and DNR on the FAR RIGHT VFO-B.

The picture shows the two (2) pushbuttons . . .

The radio will turn on normally except that when you access the "Tx BW" menu #104, you'll see that the "3000WB" has been replaced with "TTBF". So now, "1-30" is still the same, 50hz to 3Khz but the newly added "TTBF" has 50hz to 4Khz Tx BW. The SSB Rx BW is still 40hz to 4Khz. You can return the radio to 3Khz SSB BW by repeating the same steps at turn on. Very simple!

The FT2000 SSB Tx BW can attain 4Khz!!

The FTdx9000 and FTdx5000 can be programmed to a 4Khz SSB Tx BW, so should the FT2000. That's what I've always believed and sure enough, it can! Yours truly was the FIRST to find the magic buttons even though others posted (K3UR, KC4PE and others) as if they found it.

So how is it done? Access Menu #85 and look at all of the entries. One of them is labeled "1-30" and another "3000" or "3000WB". "WB" stands for "Wide Band". As you read in the "How to EQ . . " section, both are identical. So the "dual" entry implies that the "WB" can be made to extend further. And it can!

How? Simply do the following;
With the radio "OFF", press and hold the CONT and DNR buttons while pressing the main Power button.

How to
                              get TTBF mode on FT2000 The picture shows the two (2) pushbuttons . . .

The radio will turn on normally except that when you access the "Tx BW" menu #085, you'll see that the "3000WB" has been replaced with "TTBF". So now, "1-30" is still the same, 50hz to 3Khz but the newly added "TTBF" has 50hz to 4Khz Tx BW. The SSB Rx BW is still 40hz to 4Khz. You can return the radio to 3Khz SSB BW by repeating the same steps at turn on. Very simple!

Unfortunately, the EQ schemes that I've developed for the "3Khz" Tx BW need to be augmented to take advantage of the increased 4Khz SSB BW. I've added a new section to compliment the 3Khz EQ section called "How to EQ the FT2000 - 4Khz Tx BW". Click here to see my current audio rack settings.   The old section was renamed to "How to EQ the FT2000 - 3Khz Tx BW".

The new TTBF EQ section will build as time progresses. The MP3 clip below demonstrates the fuller 4Khz SSB audio captured by Duke, NA1A on a Flex5000A @ 4Khz BW. The extra BW, results in a more "relaxed" and "open" sound. This clip shows that fullness can also be had at the same time!

. . . QST Magazine Rankings of the Modern Day Radios . . .

Recently Hans, PA1HR created a summary of the QST reviews of modern day radios. These include Flex6600A, Elecraft K3, varios Icom radios and the Yaesu line including FTdx9000, FTdx5000, FT2000 and FT950 to name the more popular radios. This update shows the new FTdx101D

Be prepared for a <<SHOCK>>, the FTdx5000's rcvr is a brick-wall of 114db! Even the SSB transmitter's 3rd Order IMD specs are apx 10db better than the next closest radio!!! And the newly released FTdx101D is now ranked "2nd" but if you look carefully, it could be #1 depending on how you sort/rank the data!

The format of the report is "landscape" in order to better fit the large amount of data for each item. It also has a "Power Amplifier" section to review and rank the many HF linear amps available going back to 1997. New addtion for this month: Flex 6600M.

Many disagree with the ranking method used stating that the method is outdated and gives false impressions about the radio. Sherwood uses "Sorted by Third-Order Dynamic Range Narrow Spaced" as the "top" criteria so this results in a dramatic change in radio's rankings!!!

Here's the "Sherwood" report: Click here to see the ranking report. The top radio today is the FTdx101D . . . and the FTdx5000 is ranked 12th based on the criteria. My old FT-2000D is ranked . . . 124th!!! It's a wonder I can hear anything???

The FT2000 is the 3rd generation in the lineage of the high-end "FT" line of radios. The original, the FT-1000, was released in the 1980s. This proved to be a very reliable radio. I can vouch for that since I had mine 18 years! Next was FT-1000MP which was released in the mid 90s. This was a 'hybrid' since it was Yaesu's attempt to marry analog and digital techniques. In early 2000, the FT-9000 series was released. Finally in 2005, the FT2000 was released. This radio contains the best of the "old" analog radios and the "new" digital world of electronics called Digital Signal Processing [DSP].

A word about the FT-1000; a great radio which never made a big splash on the ESSB world until the mods I designed and implemented made it a real 'sweet' player [60hz to 3.2Khz Tx; 50hz to 5Khz Rx]. All of the filters used in the FT1000MP mods were directly taken from my FT1000 development. If you want to see the details, click here.  Too bad that the techniques involved a lot of ckt part changes which put off a lot of FT1000 owners.

The information here centers the use of external audio equipment and, secondarily, use of the internal parametric EQ to attain improved Tx ESSB audio. The techniques described here are directly applicable to the FT2000, however the recommendations are applicable to any modern HF transceiver.

The capabilities of this radio seem, at first, overwhelming. But once you spend some time looking at the operational manuals, browsing through the schematics and playing with the knobs, you see the best of all worlds is built into this radio.

The "Technical Supplement Menu" section contains the "service" documentation for the FT2000 and DMU module. Each PDF contains the schematics, board layout and parts-list of all modules. This data is a must if you plan on making any changes. Also, the "Alignment" manual contains the "how-to-do" instructions including the required test equipment to properly align the radio. Please RIGHT-CLICK and select "Save Target As" to download the PDF files. The main Service Manual is 25Mb! The Owners Manual's internals can be copied and/or extracted to other programs.

Let's take a short tour . . . . Studio
This room was remodelled recently and the goals were to make it clean, comfortable, well lighted and organized, all of the things that the former studio was not!   Also made sure to have lots of 120 Vac outlets.   To that end, a new service line was added which makes 36 outlets available!   The studio is also wired for 240Vac which powers all radios (FT2000D + TS-711) and AL-1500 linear and Y0-301 scope.  I recommended doing this b/c it isolates the high current draw devices and improves the power transfer efficiency.

The air conditioner was recently replaced w/ a new LG 8500BTU unit. A/C makes radio operation a pleasure on hot summer days.

The computer system has been 'upgraded' w/ a new monitor, keyboard, printer and scanner shown in the picture below.

The large 20mtr mono-band antenna spread out over the deck and pool as the picture shows and it provided a "resting-place" for all birds to constantly 'bomb' the real estate below. After 35+ years, they won so all of the antennas were removed.

It's been over 8 years and all traces of birds and their droppings are gone. So I've put up a different, mostly smaller, antennas and these have Bird Spikes added to the elements and boom. This product prevents birds from landing and there is no mess to clean up on the deck or in the pool!

My current plans include putting up a LJ-203BA, a 3el 20mtr monoband yagi and a Create Design, CD78 75/80 dipole. On top of the tower is a Hustler G6-144B 6dB colinear antenna, all with Bird Spikes mounted on all potential bird-landing surfaces!

The picture shows George, W6ZZ [sk 11/15/14 - rest in peace], Terry, N6CW and yours truly along w/ our respective ages. The "Old Amigos" continue to ride! The alternate picture shows a closeup of the CD78 feed point taken by my "hand held" Panasonic DMC-TZ5 camera on the ground at 17x zoom! Amazing Optical Stabilization; even the label on the DX Eng balun is clearly readable.

CD78 Dipole Analysis
The CD78 is an amazing antenna for it's size. The 75 mtr gain is lower than a full size dipole b/c of its reduced size, apx 58 ft from tip to tip but since it can be mounted high on a tower, the height makes it very efficient b/c of the lowered radiation angle. It also loads on 20mtrs perfectly. I've used it on 15mtrs w/ the FT2000's automatic tuner.

Using antenna software called Antenna Optimizer [AO] by K6STI, Brian Beezley, I checked to see what it would take to increase the gain. AO was able to quantify the gain loss due to the dipole's "coils" and then show what can be attained with lower loss coils. Click here to see the AO analysis results.

After 41 years of studying birds, I've found the "secret"; if you wish to be bird free, you MUST not let them land. If you do, you WILL have a bird problem. It's as simple as that!

Oh, Oh, there's bird poop on the deck

K6JRF's Tower Base The tower is a 13 year old crank-up tubular tower by US Tower MA-850MDP. This base system, MARB-850 rotator base, is planted in 6' x 6' x 4.5' of reenforced concrete and is bolted to the concrete via the four (4) 2 inch diameter bolts. Besides holding the tower, this allows for easy leveling of the overall structure. Also the base allows the tower to fold over when it's fully collapsed via the two 2.5 inch triple hardened bolts used as hinges!
The five (5) section tower sits on a trust bearing supplied with grease fittings in order to keep rotational wear to a minimum. The bottom plate supports most popular rotators. I've used the HyGain HDR-300 rotator (5000in/lbs of rotating torque) for 13 years with no problems.
The tower system was purchased with the positive pull-down feature. This feature is very desirable during high winds. If you've gone though this, then you know what I mean!
The reversible 1/2hp motor mounts a 1' pulley driving about 10:1 reduction gear that powers the worm drive box with another 40:1 internal reduction. With all this power, it breaks tangled coax (or anything else) without hesitation! Unfortunately this has happened at least once!
The upper spring and pulley assembly takes up slack in the positive pull-down cable that goes directly to a tie point on top of the tower.
The tower is controlled by two (2) limit switches that set the highest and lowest points before the motor power is cut off. The control box is basically a junction box for 120Vac and contains reversing and limit switch wiring.
The ladder allows you to climb the first section (20') when it's fully collapsed.

Linear Amps
New HF Amp
click here for larger picture
This new HF amplifier is just great addition to my studio. The Ameritron AL-1500 uses a single 8877 (3CX1500A7) tube from Eimac and it outputs 1500W for 40 watts drive. The amp has an Electronic Bias Ckt (EBS-1) which cuts the tubes off very cleanly between words. Thus the total dissipation is kept remarkably low and, even more important, the heat buildup is minimized. Check here to see how it was mounted into a tight space. This is my main amplifier.
I never thought that I'd never sell this amp but you can't ever say "never"! I don't use it so, it was sold to Jerry, W6XI and the pic shows that it's headed for a new home in Arizona. The amp is 35+ years old and it's never 'failed' or even hiccuped! Jerry will enjoy this amp from now on . . I sold it to him if he guaranteed that he wouldn't beat me in the pileups . . .

Audio Rack and Mic
Detailed Audio Rack View:
The Behringer MIC2200 preamp has a combination tube and solid state amplifier that gives the best of both worlds. A tube preamp in general gives a warmer sound to the audio from the mic.
The Behringer Ultra Curve Pro DEQ2496 is a unique audio dynamics processor that employs 24-bit A/D/A converters in a 96Khz sampling environment.
The DDP is a unique audio dynamics processor that employs 24-bit A-D and D-A converters under control of a dBx developed DSP chip with a LCD display. A truly marvellous dynamics unit in one increment of panel height.

Neumann TLM-103
click for detailed picture
The key element in audio work is the microphone and there are as many opinions as there are microphones, so here we all tend to get subjective. The best overall mic is probably a 'dynamic' such as the Electrovoice RE20 or Shure KSM44. These mics produce audio with little or no coloration.
I personally have settled on the 'condenser' style mic because of its high sensitivity (typically 15db more sensitive than a dynamic), and broad pickup pattern. Currently I'm using the Neumann TLM-103. It's a great example of a well engineered and quality manufactured product albeit pricey! The Marshall MXL2003 is a good condenser microphone that is reasonably priced.
For those who don't want to spend a lot, try the Shure C606 dynamic mic. Priced around $25 and it's can be used directly (XLR connection) into the FT2000 or FT950 using the internal EQs with a 75hz to 12Khz response and a rise starting at 1Khz. Marvellous mic for the price.

. . A Tribute to W2ONV, Bill Salerno . .
W2ONV became a SK on Aug 12, 2007 due to a battle with scleroderma. His disease became aggressive and quickly caused other immune diseases resulting in the taking of his life. A sad day for all Ham Radio.

Bill had been "one- two, one- two" for so many years before anybody took notice that many incorrectly attribute his SSB experiments to the early 90s. In truth, he had been doing that in the late 80s and, in fact, I would "stop-by" 14.178 and ask if he got it "right" yet. He'd reply that when he got to "three" he would be close! I asked why he was wasting so much time with this "hifi" audio. One of my problems, was simply that I couldn't hear it b/c of a "standard" rcvr bw of 400hz to 2400hz. His radio transmitted 50hz to 3.5Khz, so that's why it was a mystery to me!

The Spectra Plus chart captures the essence of Bill's SSB audio.

After getting interested in this new art-form, I became a regular stopping by usually in the evening to carry on. Many don't know this but it was Bill that charged me to make an "ESSB" player out of the FT1000 radio. Yes, it was he that got me and the project started.

About a 6 - 7 months later, the new FT1000D ESSB radio was born. The radio continued to evolve for another year as more advanced mods were done. The details of how this was done are on my FT1000 web pages here . Suffice to say, that this delighted Bill to no end. He would mention it every time he found me on frequency. He was so proud that it was done and a member of the 'group' did it. That's the kind of man he was.

I left active ham radio in 2000 or so and was off-the-air until about 6 months ago. I removed all of my antennas so I couldn't get on the air even if I wanted . . . and believe me, I wanted, mainly to talk to Bill. As I was 'getting' ready to come back, I was told of his passing. All I can say, it was as if my father had passed. It delayed me for at least, another 6 - 8 months before I got over his demise.

When I was setting up the "external audio rack", Bill said that he had the 'magic' setup info that will give you great audio. At that time, I was naive enough to believe him so he said he'd send me the proven Aphex setup info.

                                Secret Aphex Adjustment Sheet Here's the sketch of Bill's setup (click for larger view) that he used when he ran Aphex audio processing. It was well marked meaning it had made the 'rounds'. The "key" was the Aphex "Big Bottom" setup outlined in the blue box. The BB drive . . . "must be exact"! Nothing against Aphex (and Behringer, etc) but the BB circuit was a 'joke' . . The only thing that's a 'secret' is the fact that all audio is mainly dependent on the 'voice' and mic driving the rack. However, I treasure that info and have shared with you all today.

. . Ham Radio Deluxe . .
Speaking of knobs, I'm not much for marrying a computer w/ a radio b/c I'm basically an old-timer and I still love buttons, knobs and sliders on the radio. Well, last night, I decided to try a Software Defined Radio (SDR) program so I d/l the latest version of Ham Radio Deluxe (HRD), V4.0 SP4 build 1901 and installed it. The work that has gone into the development of this fine program is to be lauded. Simon Brown, HB9DRV has done fantastic work to bring the program to this latest state of perfection.

Front Panel of FT2000 I works so well that I couldn't believe what I saw. All functions work so nicely and effortlessly, that I was taken back. All of the buttons and knobs on the radio are available in HRD they all work as advertised.

The picture shows the basic FT2000 radio setup (sliders are not shown). You can either click a button on the screen w/ your mouse or use the radio. The program has many features and one of these is the "DX Cluster" announcements right on your screen sorted by band. If you're interested in a particular station, you simply "click" on the station and your radio changes to that frequency and aims the antenna. It takes the "work" out of chasing DX.

The program can be downloaded here.    Scroll down to the "Installation" section and click on the highlighted "Download". After the d/l completes, click on the main file EXE program to start the installation.
