Re: [Elecraft] K3 Receiver frequency adjustment

Amen, Dave.  After all, the "retail" DX cluster network rounds frequency to the nearest 0.1 KHz.  I think RVZ could do worse than to use WWV at 10 or 15 MHz to verify his K3's calibration And FWIW, a word or two from the RBN perspective - we have been working for several months to improve the

Re: [Elecraft] K3 Receiver frequency adjustment

All good advice BUT ... before you do anything, look up Wayne's RefCal procedure on the Elecraft site. I think Don, W3FPR, may also have it.  It's not hard, you just have to go slowly and be very meticulous at each step.  I have my K3 #642 within 1 Hz of WWV, and it stays there.  It's a fun adj

Re: [Elecraft] K3 Receiver frequency adjustment

Look in the manual for Ref Cal calibration. But before you go Messing there, tune radio to WWV on 10.000, 15.000 or 20.000 MHz and see if it’s really you or the other guy that’s off. Now check for procedure. The zero beat works well and can get you within a Hertz or two Sent from my iPhone .

Why don't you check an actual known frequency???  Relying on packet spots for anything seems foolish to me. Dave   AB7E On 9/20/2020 12:04 PM, RVZ via Elecraft wrote: Hi Guys, My K3 receiver is a little off frequency compared to the frequency stations are spotted at.  I realize that Packe

Re: [Elecraft] K3: KIO3 digital board failed (I think)

Working with Rob at Elecraft Service, I removed and checked the KIO3 Digital I/F board and found L1 blown. L2, L3, R12, and R13 are all good. L1 is on the ground lead from the sub-D9 connector, pin 5 to ground in the K3. Definitely blown as there is a carbon smudge next to L1. I installed a

Re: [Elecraft] K3 Audio from RS232 connection?

You can use the line in/out connectors in the back of the radio and a "sound card" for your computer. USB sound cards are available inexpensively from Amazon. I have one for my KX3 which I think cost about $5.00. You may need to install a pad to lower the signal level between the line out on th

Re: [Elecraft] K3: KIO3 dgital board failed (I think)

I had exactly that same problem, Ed, and I also first thought it was the USB/RS232 cable (which it wasn't).  I also do not need the direct USB connectivity, or the associated internal sound card. Luckily, I was able to buy replacement boards from someone who had done the upgrade to the KIO3B

Tune before you run wsjt. The ATU I think forces the VFO into CW mode. Split in a DATA Mode is not allowed if one VFO is not in same DATA Mode. Sent from my iPhone ...nr4c. bill > On Sep 10, 2020, at 12:57 PM, David Needham wrote: > > Bill, > > It looks like you have uncovered the same a

Re: [Elecraft] [K3] KAT3 not functioning on 6m

No, that’s not it. The right is ALREADY in split mode when i attempt to use the auto-tune. You get the N/A flash if VFO A and B aren’t set to the same mode, other than SSB/CW. WSJT-X sets it up correctly, with both VFOs in DATA mode. > On Sep 7, 2020, at 9:50 AM, w4sc wrote: > > Bill, >

Re: [Elecraft] [K3] KAT3 not functioning on 6m

The K3 allows split in data modes, but only provided both VFOs are already in data mode. The K3 will not allow cross-mode split between Data and CW/SSB. If you are seeing "SPL N/A" when you try to enable split with VFO A in a Data mode, what that tells me is that VFO B is in CW or SSB, not in Data

Re: [Elecraft] [K3] KAT3 not functioning on 6m

Bill, The K3 only allows the “split” mode for SSB and/or CW to be enabled, at least from panel. Trying to enable split in any other mode, the VFO B window flashes “N/A”. You may have different indications / results if the split command is sent via the CAT, and a mode other than CW or SSB is
