WINMOR Youtube Video

Hi All,

Here is Youtube video of WINMOR on RMS Express in action.
This was before the software was very robust, and I used the video to record a crash.
This was done between two laptops with acoustic coupling (microphones and speakers), and the internal sound cards. No radios and no RF.
Note the CPU usage. About 20 % on a 1.5 GHz laptop.
Also note I had to trip the "Busy Channel Indicator" at the beginning. (Due to noise into the microphones.)
Note the automatic "gear shift" to 8Car V16PSK.
Note the CPU spike at the crash.
WINMOR does NOT crash anymore, and is very stable, fast and robust now.

The antenna tuner in the Kenwood TS-480 (like most built-in tuners) isn't wide range enough to get a good match on all bands with a 23' whip. Its maximum matching range is up to an SWR of 3:1. Its still a good unit, and it might be fine for some bands, but for boat use I would use it with a wide range autotuner like the SGC-230 at the base of the antenna.

Yep, I have a ts-480 with the built-in tuner. It would be great for fine tuning a dipole, or the like, but not a long wire or whip. The only complaint I have sofar is that the microphone using fragile ethernet-type connectors, which can, and have broken. I will be putting some strain relief on ours once it is installed on the boat.

OK, wait. If it cant tune correctly, why are you installing it on your boat? This radio stuff hurts my brain...

Yeah, it is headache producing, radio stuff.

The built-in tuner will not tune a long wire or long whip. An external turner, like the SCG, will, which is what I have.

If I had the room, and wanted a HAM (not SSB) radio for the boat, and was buying new, I would get the new IC-7200 from Icom. It has a USB connection direct to the PC. When used with WINMOR, it does not need an external sound card or device, no modem, just the radio linked to the computer. Very nice. Alas, it is too deep for use at our nav station (and I already have the Kenwood).

I take it the 7200 also needs an external antenna tuner? If the Kenwoods tuner is lacking, how is it possible that yacht successfully transmitted emails from Brazil to Halifax? Just lucky that day?

The simplest form of antenna is perhaps the dipole, which you can use for a specific frequency, without a tuner. Antennas have to be length matched to the frequency you wish to transmit on. For receiving, just a long wire will do.

The tuner in the TS-480 allows you to use such an antenna, and perhaps vary the frequency a bit, without either using a different antenna, or a separate tuner.

To answer the question, yes, both would require an external tuner for use on a boat, when using either a whip or a random length of wire. What an antenna tuner does is make the antenna look like a specific length, electrically, to the radio.

A great book to start out with, and one that I bought for this reason, is "Ham Radio for Dummies". This filled in alot of blanks for me. Then I studied online for the techicians test, without buying another book, but using the many online resources.

Chris, thanks for the info and the book recommendation! It's on my Amazon wish list right now...

Guys,

A real Ham can tune any antenna to resonate on any frequency.
Even the shrouds, or the lifelines, or the 3ft6in barbed wire fence on the farm (done all that- excellent NVIS antennas.)

Of course for a 3500 NM path you need a vertical antenna for a shallow transmission angle.

Here is what you need:

ANTENNA TUNER - MFJ-948: 300W, 1.8-30 MHZ, CROSS METER - eBay (item 330397496848 end time Jan-27-10 19:00:28 PST)

Hamsailor.

Vertical dipole antenna.

With this antenna, you don't need a counterpoise or ground.
Also maybe do not even need the antenna tuner, if you just want to operate on one ham band, like 20 M.

You could also hang it from about 1 ft from the top of the mast and tie it off a few ft from the deck just ahead of the shrouds.
For marine strength, the legs could be made out of insulated lifeline.

So they have actually made it proprietary? That's amazing! Hehe. Even the Winmor page @ winlink is full of free the code requests

Well, $39 Winmor or $1200 Pactor...

Yep, they did it. $39 for Winmor RMS Express...!

But, give them their dues. They have worked hard on this. Now we all have free airtime radio email over thousands of miles while Sat email is still expensive and spotty. And we don't have to pay $1200 for an Iridium sat phone or Pactor 3 TNC. (Amazing how those two cost the same....)

And yes, not sure how open the software will be now.

Just hope for their sake that the Winmor-enabled Winlink 2000 system will be much expanded and ultimately worth the while of the time and effort that us free Beta testers have put into it.

Developers of other applications will also be using this WINMOR TNC app as their virtual TNC. That's where the Winmor developers will make their money. (Not as hams, but as retired software engineers.)

I was always interested in that GAM split backstay antenna: http://gamelectronicsinc.com/mike.promoREV.120605.pdf Bet it works just fine!
