For a homebrew rig, I would recommend looking at the recent QST articles by W7JI describing his 40 meter receiver and transmitter. I believe they were in the Feb and April 2011 issues.
Just finished building the receiver, and it works quite well. Fairly easy build with all parts inexpensive and readily available. I built mine Manhattan style using a RF proto board. Easy alignment and fairly good performance. As a RX, I'd rate it slightly inferior to a K1, mainly due to lack of an AGC loop. But it does have an audio limiter that partially addresses this. If you do go that route, make sure to check the ARRL website and feedback for the latest corrections. There were a few errors in the original article. 73 Craig AC0DS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
