I've had some time to play with the brand new K2. It appears to be working great! I actually read the manual and I think I might understand the filter bandwith/BFO stuff and what CAL FIL is doing. I have a question or two ... off-reflector replies are probably appropriate since the traffic on this reflector is high:
I left a lot of my hearing in SE Asia, but I have a "sweet spot" at about 650 Hz or so for CW. I'd like the pitch of the received station to stay at that freq when I change filter BW's. I succeeded in getting it close for CW NORM -- sort of an iterative process. I did finally figure out that I needed to center the signal in the narrowest filter, set the BFO for the right pitch, and then set it for each of the wider filters. 1. Should I be able to do the same thing for CW REV? What I'd like is that filter setting and NORM/REV have no effect on the pitch of the signal centered in the passband. I did a quick VFO calibration before I took the K2 to Alpine County for CQP. It is still about 250 Hz off, I think. (The CQP Alpine County expedition is a different long story!) 2. Should I do a good VFO cal first, before fooling around in CAL FIL or does it not matter? 3. Based on the initial VFO cal, I have a suspicion that I'm at or near the end of the range on C22 and might not be able to get it right on. Other than the obvious display error, is this a factor in getting the CAL FIL process completed? Is there a way to fix it? I have a calibrated service monitor. FWIW: 9.9 W out on 10m, and over 10W on all other bands ... I wound the toroids and binocular as stated in the book. (This is on a 12V gel cell for power). Thanks to all for all the help during the construction, it was fun. And so is operating with it. 73, Fred K6DGW Auburn CA CM98 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
