I prefer to use my radio operator skills, no fancy filters, displays etc etc. And, try Fri, 14 Jun 2013 18:25:02 GMT Zack Widup http://groups.yahoo.com/group/PPLL-VFO/message/274 http://groups.yahoo.com/group/PPLL-VFO/message/274 Interesting. I've thought of at least trying something about that. Do you not use a computer at all?

Glad you got it working. Not bad for a little, tiny PIC, huh? Will be looking to see what kind of design you come up with for the phasing Tue, 14 May 2013 01:35:58 GMT wa5bdu http://groups.yahoo.com/group/PPLL-VFO/message/271 http://groups.yahoo.com/group/PPLL-VFO/message/271 Hi Craig & fellow Si570 users. I bought the little Si570 card a few years ago but didn't get the controller card. As far as I'd gotten was to do a little bit Tue, 30 Apr 2013 12:07:11 GMT serracin7388@... http://groups.yahoo.com/group/PPLL-VFO/message/270 http://groups.yahoo.com/group/PPLL-VFO/message/270 The R2PRO and similar receivers/transceivers that use the same local oscillator , as the operating frequency suffer from hum. And it is very difficult to Tue, 30 Apr 2013 00:01:28 GMT kb5zxm http://groups.yahoo.com/group/PPLL-VFO/message/269 http://groups.yahoo.com/group/PPLL-VFO/message/269 There is an article in QST magazine recently about this or similar doings Mon, 29 Apr 2013 23:58:25 GMT kb5zxm http://groups.yahoo.com/group/PPLL-VFO/message/268 http://groups.yahoo.com/group/PPLL-VFO/message/268 I am looking at doing the same, but in hopes of bring back old test equipment, and making it more freq agile.
