Hi all, Finally finished the K2 last night, all that remains is the final assembly but I've run out of parts except the speaker and a couple jacks and screws here and there for the final assy.
I made my first, and as far as I know at this time, only, mistake when putting in the LP filter coils. when winding L21, I was looking at the turns spec for L22. I happily soldered it in and while admiring my work, noticed the wrong number of turns hi hi! So I at least caught it before I'd continued on with the build. Some solder wick and a few 4 letter words and I got it out. There was enough lead left to go ahead and install it at L22 where it was supposed to go so no harm done in the end. Like I said, Im hoping that's my only mistake! The last part of the alignment seemed to go correctly. A couple things I noted were first, in receive, peaking the bandpass filter coils had a practically undetectable peak. So I was worried that I'd messed something up. But on the xmitter alignment I was able to see a detectable peak on the wattmeter so that indicates to me the filter is working. The only other thing is the current draw in transmit seems slightly high on 15M when I (of course very breifly ;)) max out the power output. The current draw seems to go up to about 3.5 amps on the internal ammeter. The rest of the bands seems like around 3 amps is the max. Otherwise, it seems nominal and the same as other bands at reduced settings like 5 to 10 watts. Wasn't sure if there was some parasitic oscillation or anything going on. the power output looks steady on the wattmeter and the recieved signal in my 706 sounds clean. Would this happen to sound familiar to anyone? Before I put the cover on I'm going to do as Don suggested and run through Wayne's alignment procedure on the 4mhz oscillator and display calibration to get that hopefully finalized (if I can RX WWV this morning that is ;)). But all over but the shoutin' at this point ;) Tnx es 73, LS W5QD -- View this message in context: http://n2.nabble.com/K2-finished-tp4566224p4566224.html Sent from the [K2] 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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
