[Fwd: LF: RF Tech notes, and reminder for SAQ transmissions]

[Andre Kesteloot]

Greetings everyone,

Just found some interesting PDF's about HF designs, mixers, 
demodulators, receivers etc, at

http://www.wj.com/technotes/index.asp

Interesting reading, though some articles may be a bit old (and no, I 
don't work for that company).

Futhermore, just a reminder that SAQ makes transmissions with their 
historic 17.2 kHz transmitter the coming weekend. Got your mechanical 
receiver ready, Jim ? ;-)

Regards,
 Wolf DL4YHF .
