Hello all, I'm now a bit further along with my K1-4 build, and I just installed the VFO toroid (L1) on the RF board, fired the radio up and adjusted the winds to match the desired range. Shortly after that I was switching through the four bands as instructed, and I noticed that my radio is showing the following four bands: 40m, 20m, 17m, 15m ... **no 30m, and both 17 and 15!** (specifically, it displayed 7 MHz, 14 MHz, 18 MHz, 21 MHz).
The first thing I did was re-check the crystals on my filter board very carefully with the K1-4 filter board manual. All are correct, in their correct respective spots, grounded, and I made the right crystal selection for 80kHz tuning. I then checked resistance again across the IC (U1). Everything looked good, though a couple of values were just barely higher than their recommended range: UI pin 8, UI pin 9 == 450 ohms (should be 360 --> 440 ohms) UI pin 9, UI pin 18 == 455 ohms (should be 360 --> 440 ohms) 1) Has anyone else experienced this problem of a missing 30m band while having both 17 and 15m present? 2) Does any of the above described info on my filter board sound suspect, or is there something else I should check? Thanks for your help, and 73, Mark (KB3OKS) _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
