Hi Alan, I did the reset on the K3, but to no avail. I'll try on the P3. But I'm suspicious that the P3 is not the problem since it merely examines a fixed IF bandpass. No doubt the P3 *is* the problem for the NaN math error, but not about the flat-line showing in the display. Eh?
So it really looks like there are two separate issues here. Somehow the P3 has to know what frequencies it is looking at, so it can show numeric band edges, center frequencies, and marker positions. All of these are messed up on the 6m band. Hence the K3 must be sending information that either (A) is badly hosed up, or (B) the P3 can no longer handle properly. The second issue is the apparent lack of signal coming from the K3 to the P3 for display in the spectrum analyzer and waterfall. Surely the P3 is not in charge of the signal arriving, or is it? This problem did not exist in older revs (about a year ago), as far as I can recall. I just noticed it recently when I tried to zero-beat the reference oscillator to the 5th harmonic of my Rb oscillator in the shack. But I could be wrong about distant memories too.... - 73 de Dave, N7AIG On May 31, 2012, at 12:22 PM, Alan Bloom wrote: > Hi David, > > On Wed, 2012-05-30 at 21:14 -0700, David McClain wrote: >> Hi, >> >> A few weeks ago I upgraded my P3 and K3 to firmware P3 MCU: 1.16 and >> K3 MCU: 4.48.
