[Elecraft] [K2] CAL-PLL Question

Don and Dave, thanks for the responses. The idea with the ground contacts is interesting. Regardless of whether it makes a difference, I will check and clean the contact surfaces once the next time I open the base plate. I have not paid attention to this detail before. 73, Wolfgang DL2KI --

Re: [Elecraft] [K2] CAL-PLL Question

The only reason I can think of why this might apply is if the grounding of the bottom cover was poor. Whilst it certainly can be poor, because of paint not having been properly masked around the mounting blocks, and I recommend cleaning all paint off, around them, I'd be surprised if enough

Re: [Elecraft] [K2] CAL-PLL Question

Wolfgang, In my experience, that is not necessary. It IS necessary to have the bottom cover in place before running CAL PLL. 73, Don W3FPR On 7/30/2022 11:25 AM, Wolfgang wrote: Hi, in a german QRP forum I found this hint from Peter, DL2FI (SK).    In any case, the PLL calibration must be

[Elecraft] [K2] CAL-PLL Question

Hi, in a german QRP forum I found this hint from Peter, DL2FI (SK). In any case, the PLL calibration must be redone whenever the bottom cover of the K2 has been opened. This statement does not correspond to the instructions in the K2 manual and other contributions here. Also, I can't

[Elecraft] K2 CAL PLL Error 232

I reset the EEPROM on my K2 SN#4454 because it stopped responding to COM PORT 1 commands from Ham Radio Deluxe. This cured this problem but now when I turn the radio dial the frequency readout changes but the frequency is not changing only on the 40 meter band. I am attempting to run CAL PLL but

Re: [Elecraft] K2 CAL PLL Error 232

Bill, It sounds like the 40 meter frequency is incorrect - the K2 detects that during a CAL PLL attempt. Do you have the K60XV installed or the rework eliminator for the K60XV option? If so, enter the secondary menu and once again set D19 = y - your master reset would have wiped out that

[Elecraft] K2 CAL PLL

Hi, all concerned: I get the operation of the hfo in general terms -- the PLL part, anyway. I'm looking for (links to or) a fuller explanation of what happens in this process: number of points, interpolation, etc. TIA 73, Dave, N3HE ___

RE: [Elecraft] K2 CAL PLL

Hi David, I'm looking for (links to or) a fuller explanation of what happens in this process: number of points, interpolation, etc. To find out on your own, you could try this: 1. Get a stable CW signal source. 2. Get the spectrogram program. 3. Setup spectrogram for very high resolution. 4.
