Are there any good articles or kits for 2c39 amplifiers? The one the in arrl handbook needs a small machine shop to build. Does anyone make kits? Any help would be appreciated.

They will maround 20 watts linear and almost 30 watts saturated with under one watt drive. A suitable driver is also available.

Both of which will be running at the same time. The speaker audio will be available to both TNCs.....and not necessary but maybe a nice extra...to allow the other TNC to hear the output from the TNC that currently keying the transmitter. The main thing is a circuit so that only one of the mike/ptt pairs can key the transmitter at a time. The other one should be blocked. The radio at present is a Handheld radio, though the possibility exists that some other radio (with separate PTT line) maybe used in the future. -- --EMAIL-----------------------------PHONE-----------FAX------------ | WORK: lawrence@combdyn.com | (403)529-2162 | (403)529-2516 | CallSign | HOME: dreamer@lhaven.uumh.ab.ca | (403)526-6019 | (403)529-5102 | VE6LKC ------------------------------------------------------------------- disclamer = (working_for && !representing) + (Combustion Dynamics Ltd.); ------------------------------ End of Ham-Homebrew Digest V93 #110 ****************************** ******************************
