Yes!
Took me a couple of hours messing around with the settings, but I finally got it to work. I have a JR 652 radio and am running Windows 2000 with a Sound Blaster Live Value sound card. I used a simple 6' long 1/8" mono mini-plug cable purchased from my local Radio Shack without any transistor. (Probably the same cable JR sells as a Trainer, but I'm not certain). It sure beats soldering a bunch of elecrical components or paying 40 bucks or more for a USB interface cable! - But you will have to do a bit of soldering if you own a Futaba or Hitech, the info is on the web site noted above.
I couldn't get it to work on the Microphone port on the sound card. The Microsoft "Sound Recorder" did register the input signal when the radio on the microphone jack, but for some reason FMS could not pick it up at any input volume level.
So I used the Line-in port instead which worked fine. I set the input volume control to about 30% of maximum (set from from Settings->Control Panel->Sounds and Multimedia).
One VERY important thing is, if you use Sound Recorder to test the input signal TURN IF OFF BEFORE YOU LAUNCH FMS - the Sound Recorder somehow interferes with the signal and will not pass it through to FMS.
And it's also important to make sure that you download and install the latest drivers for your sound card for Windows 2000/XP first! The default Microsoft Drivers for Windows 2000/XP are bare-bones and may not have all of the features activated.
Seems kind of weird controlling FMS through the line-in jack of a sound card, but it works!
Kudos to Tsutomu Seki, a very ingenious fellow. And thanks to Shinichio Nishiya for bringing it to my attention!
