Good news - the rig is on the air! I have made two QSO's on it so far. I tried holding off to get one of my friends to give me the first QSO but I scrolled past a guy calling CQ and just couldn't resist HI. So I have two QSO's on the rig so far.
I tuned the filters first with the receive method. I keyed up one of my other radios in to a dummy load and tuned the filters to peak the meter. I adjusted the power out of the radio so I got close to a jump in the meter on the K2. Then I fine-tuned the inductors and caps more. After the receive test it was on to the transmit. I peaked the filters for power out (based on the K2's internal metering while in "tune" mode). In most cases I was very close already. A couple of issues that need resolved - First - the buttons on the right side of the rig don't always work right. Specifically the filter button and the ATTN/PRE. They seem to have crossed signals with the display, band up, and band down functions. Any ideas on this one? Most notably - the filter button scrolls through the bands instead of adjusting the filter width. Second - I wasn't able to get any more than .6w out when I did the transmit test on 17m. It seems to me the caps were very touchy during the receive test. I was using a metal screwdriver to adjust them and that was playing all kinds of havoc on the tuning. So I went back to the tuning tool that came with it. The reason I wasn't using it before was because the caps were stiff and I didn't want to break the tool. Oh well - theres a reasn why the tool is plastic, eh? HI. In any event, I will get back over to my buddy's place with the test lab and peak the filters. 17m really seems goofy to me though. I was able to get nearly all the other bands cose on the receive tuning. Then when I hit 17m I couldn't get the power to go up for nothing. Hopefully this one is just being difficult and will be tuned in easier in a lab session. The buttons are also a bit of a concern. However, the transmitter and receiver work for the most part.
