Hi All
I have been building this K2 taking my time and I thought I was soldering carefully. All has gone well so far and I have got as far as the IF amplifier alignment having completed VFO linearization etc with no problems and all readings within spec. I followed the instructions for the IF alignment including putting the PreAmp on but I could not hear the internally generated signal at 7000kHz and there was only a very low audio output. With the PreAmp off (or even with the ATT on!) the audio is much louder and I can then hear that signal and so I adjusted the slug in L34 for best signal strength with low noise. I then carried out the 40 meter band pass filter alignment with no problem so I am about to start the next phase - Assembly, Part111. Clearly there is something wrong with my PreAmp on 40 meters however. Does anyone have any ideas of what I should look at or check? Happy Christmas everyone! 73 Ray, G3XLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
