With regard to network loss, here are a couple tools that I use regularly: http://www.qsl.net/ac6la/xlzizl.html (requires Excel) ftp://ftp.qrz.com/files/antennas/tl.zip (DOS app.) It's amazing how mu
Here's another home project for show and tell: http://home.rochester.rr.com/k2zn/tuner1.jpg http://home.rochester.rr.com/k2zn/tuner2.jpg The transformer is a 1:1 wound on a type 43 "squaroid" core. M
Heck, I've even killed the toughbooks in places like the Middle East. I've also used units that cost in the $6-7k range that don't fit the bill for one reason or another. Al, K2ZN

I have a #288 1.8 kHz filter for the 6.3 MHz IF that I no longer need. I'm looking for a #217 500 Hz filter for the 9 MHz IF - preferably an even exchange. 73 - Al, K2ZN
Didn't Icom put out something like an IC-767 or 757 that went through half a dozen "new, improved" versions over a period of less than two years before they finally decided to drop the product? Also,
Tim I don't think any of the mods mentioned on the page ever made it into production units. However, I do know that there were two different boards for the IF/Audio, RX Mixer, and noise blanker assem
Rick Have you tried applying a signal to the AUDIO IN jack on the rear panel? It's in parallel with the front panel mic connector. At the very least, you'll be able to verify if the rest of the TX au
Doc If you get more than one response, send 'em my way. I've been trying to sell my FSK filter on and off for over a year, even at rock-bottom prices. 72 - Al, K2ZN
