sometimes some leakage from the BNC connectors. Try reseating them and watch the scope as you do it. Dale, k9vuj

I had same experience and it was the power supply. 73 Patrick VK2PN

Wondering if anyone can help me. I see some noise on my P3, within about 25 KHz above and 25 KHz below my K3s frequency. If I move the K3 dial, the noise spikes above and below the frequency move

You can display the voltage in disp and under full load, 100 watts carrier observe the voltage drop. There might be a inline fuse holder that has some bad connects or other problems. Dale, K9VUJ

Did it work via AFSK (speaker audio from sound card wired to LINE IN) or FSK (keying circuit on Pin 1 of ACC port)? Assuming these are all FTDI USB-to-Serial devices, MMTTY cannot directly open any of

If they are tight and ‘click’ as they go together, they should be ok. 73 de David, M0XDF (K3 #174, P3 #108)

Try a shot of DeoxIT on the contacts, add a little rub with a Qtip, if there is enough room? Any electronic contact cleaner on hand should do the job too...

Well, I’d disconnect them and ensure that the internal metal contacts are clean and bright, both on the DC power cable and the K3. Also check for good contacts with any fuses in the DC supply

Tried that also Mike......they appear to be tight.! How do you check power poles connectors.? Thanks again, Rodger.

Also, might be worth checking the PowerPole DC connections to the K3. Just a thought … - 73 and good DX de Mike, K6MKF, Past President - NCDXC

Changed power supplies.....same issue power comes and goes.!!! Rodger.

Hi Rodger, Well, the other thing to check is to ensure that your connections to DC power supply are delivering sufficient voltage to the K3. Just another thing that I’ve seen reported about

That mod was carried out a couple of years ago......the power has come back for the time being, will see if I get other responses if not will contact Elecraft direct. Thanks Rodger/GM3JOB

Hi Rodger, When this happened with my K3 - #2257 – it turned out to be that I needed the KPA3 Power Connector Replacement upgrade. I had the gold pins installed and the Error 12v was

This morning while running my Elecraft K3 Ser No. 02377 at 32 watts I got the above error message. I was feeding an amplifier at the time, now power out will not go above 12/13 watts and the fan

Just this past week I successfully used NG7M's video to integrate MMTTY FSK to my K3S / ACOM 2000A station. I strongly recommend it. I really like dropping the received tones down to 915 Hz from the

Good and Long Winded... I guess that's a compliment? :) I don't think I have seen someone that create something more detailed, that is for sure. However, the detail pretty much leaves everything
