Dear Folks: I have now built a K1 (#1024) and a K2 (#6922) and have deeply enjoyed doing both. I am now currently building the SSB option for the K2. They are both great rigs, and building them and getting them to work has been some of the best stuff I've done in my ham radio career. I've worked hundreds of stations with them both, and a fair amount of DX.
Certainly, my confidence in doing my own work has grown by leaps and bounds because of the experience I've gained. I've even built one thing from scratch, just using a schematic (a relatively simple circuit, but it worked perfectly the first time). I now have a question about something I did years ago. When I got the K1, I decided to build something smaller first in order to practice soldering. I built a Vectronics (actually, from MFJ) direct conversion receiver for 20 meters (I also built the companion transmitter, and it works fine). The problem is that merely touching the receiver makes its change frequency, and tuning it is an uncertain process. As a result, it is unstable, and not much fun to operate (though it is reasonably sensitive despite its simplicity). There must be some capacitance that it is getting from my touch, that is adversely affecting its performance. Did I do something wrong in building this receiver, or is it just the price of a really bare bones design? Thanks for any advice anyone can give me. 73 de Bernie KF0QS -- View this message in context: http://elecraft.365791.n2.nabble.com/Question-Regarding-Direct-Conversion-Receiver-tp7569046.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
