I recently FTPed the schematics for a 'Baycom' modem from some odd FTP site, however they are in PostScript format, and I do not own a Postscript compatible printer. Does anybody know where you can find the schematics for this TNC in a format such as PCX, TIFF, etc.? -- _______________ Charles Marsh, a.k.a VO1VZ [-] |- == =======::| Email: cmarsh@calvin.stemnet.nf.ca _|_ |: + + + (): + :| \__/ ~~~~~~~~~~~~~~~ "I'd rather be HAMming around!" ------------------------------ Date: 4 Jul 1994 18:00:19 -0400 From: ihnp4.ucsd.edu!swrinde!gatech!gt-news!prism!prism!not-for-mail@network.ucsd.edu Subject: NEED bare-bones FM transmitter plans To: ham-homebrew@ucsd.edu Hello all! I picked up one of those recordable greeting cards the other day... even got it free, since it was a Father's Day card they no longer could sell! Anyway, after playing with it (much fun) I decided that I could hook it up to a tiny FM transmitter and have a club event, using the card's circuit to record a little message like "This is KD4UGI and you can't find me, hahaha!" and have a transmitter hunt. Anyway, what I need is just a basic FM transmitter circuit, hopefully one that can be built in a short time with basic equipment (read, soldering iron and wire cutters) and (more importantly) and can be hooked up to the recording circuit. The chip sends its audio to a cheapo small speaker, so I'll need a way to interface this output with the transmitter. Could a $10 Radio shack walkie-talkie (do they still make those things?) be easily converted to ~145 MHz, and could the power be increased slightly to provide roughly 1 or 2 watts (or a 3 mile range)?? How would I do this, and how much will it cost? Would I be better off starting from scratch? Thanks for your help. If this is on some FTP site, that's cool too, just point it out to me. 73 de G8R ******************************************************************************* * Mike "Gator" Whaley K Chief of Aerospace Engineering * * gt0265d@prism.gatech.edu D George P.

(Please note the exact title; there are 3 other books by the same author with the word "radio" in the title.) Forgive me if this is not the most appropriate place to post this request, but a) my Internet access is extremely limited and I can only read rec.radio and can only post to rec.radio.amateur (can't complain for only $5 a month) and b) I know for a fact there are a lot of sharp folks out there on this particular distro list and many of you have to have this book. (Being willing to part with it is an entirely different matter!) 73 de WA8MCQ ------------------------------ End of Ham-Homebrew Digest V94 #183 ******************************
