[Elecraft] K3 PTT vs QSK

I'm working with a piece of accessory equipment that relies on the "Key Out" (PTT) signal to switch my transmitting antenna from my K3/KPA-1500 to an SDR.  Am I right to assume, as appears to be the case, that when the K3 is in VOX/QSK mode, the Key Out jack continues to behave as if it was in

Re: [Elecraft] KPA1500 ATU question

IMO, the really critical thing to do is to follow the table in the manual and "train" the ATU at the recommended intervals on each band.  Once you have done this it effectively becomes a 1500-watt transceiver (unless, of course, you have more than two antennas per band). 73, Pete N4ZR Check

Re: [Elecraft] Any progress on K3 modules?

That's fine, Wayne.  I understand the problem, but for a while it looked like I might be in need of a KIO3 after a lightning hit.  Fortunately, that was resolved, but given the known sensitivity of this board (which would have been my third replacement) I was praying for a positive answer. It

[Elecraft] Any progress on K3 modules?

Has there been any progress on the planned final production run of the KIO3 Upgrade Kit?  I ordered one just before everything stopped in 2020, and put my name on the "last chance" list in 2021, but have heard nothing since. -- 73, Pete N4ZR Check out the new Reverse Beacon Network web server

[Elecraft] K3 serial port

Thanks to everyone who offered educated thoughts on my problem.  I just discovered that the problem apparently lay in my USB hub, perhaps as simple as a loose connector.  I plugged the USB cable into a computer port directly and voila!  So I now have frequency control communications again. 

[Elecraft] Diagnosing Serial Port Issue

My station took a lightning hit a couple of weeks ago, and I have just finished configuring a new computer with my old C drive.  That all works fine, but for some reason I'm not able to get COM port communication between N1MM Logger and my K3.  I'm using a USB-to-serial cable.  When I open the

Re: [Elecraft] KPA1500 finals replaced...

It would be useful to know more about the circumstances of these final transistor failures.  I have been running my KPA-1500 for almost three years, contesting, almost always at 1400+ watts, and, fingers crossed, so far it continues to run with my K3 like a 1500-watt transceiver.  I often

Re: [Elecraft] Systematic error in spots as heard by K3

I agree, Rich - I had used the Elecraft calibration procedure with WWV to make sure it's dead zero-beat, when I first noticed this phenomenon.  Done at 10 MHz before, this time at 15 MHz,  which seemed to be slightly different, so now we'll see how the spots sound.  Could be all it was - more

[Elecraft] Systematic error in spots as heard by K3

My K3 is set up to zero-beat at 520 Hz, and its calibration has been checked against WWV and adjusted to with 2 Hz.  That said, I'm surprised when operating assisted to note that most spotted stations, when clicked on, sound significantly higher in pitch than my sidetone.  It seems logical,

Re: [Elecraft] [POSSIBLE SPAM] Common K3 failure modes???

The only hardware failure I've had over the long life of my K3 (SN 4275) was the driver MOSFET in the KEY OUT circuit.  No idea what happened, but the transistor exploded.  Got it repaired locally. 73, Pete N4ZR Check out the new Reverse Beacon Network web server at
