PCB revision 4 on Hans' QRP Labs page states that they have been replaces with 1 uf ceramic.... you have gone with .1 uf? ceramic. Any real difference?...? I have not done this YET... but I did point out the change to Mike earlier today... as I did with a couple guys in my club who are just getting around to their kits that were sitting for a while.
tnx

Mike,
The first question is what revision of the board do you have? ?If it is 1-3 you need to replace the electrolytics C21 & C22 with 0.1 uF ceramic caps. ?That has worked on 5 radios I have built

Just finished my QCX 40 kit and it went together well. Came right up with good alignment and output at 12-16v. Problem is cw sounds terrible through the headphones/speaker. I get a loud click at the beginning and end with about a one second delay on semi-qsk. There is no sideband on anything above 20wpm on full qsk.Rechecked output and alignment which is good. Kinda stumped at this point.
