No, it's code in an Arduino Mega 256 than sequences a couple of state machines.
One state machine controls putting KAT500 in full search tune, powering the
exciter, waiting for completion of auto tune, returning exciter to RX mode.

What button is that, Andy? I set up a spreadsheet that shows the

Training a KAT500 does not require it to be in AUTO mode. I NEVER put my

Jeff,
One thing I forgot. The KAT500 should only be in AUTO mode when you’re actually
training it. i.e. You tune the radio to a frequency, then TX (in TUNE mode) and
wait for the KAT500 to stop clicking. ISTR that when a solution is found, the
KAT500 TUNE light goes off and the solution is stor

There is no adjustment for these thresholds. As far as the Auxbus, the KPA does

Thanks. That's good detail. I'll recheck the manual once more. I made a
common mistake of assuming too much and not reading enough. I have tremendous
respect and faith in the engineering put into the system of the Elecraft line..
That's a long way of saying, It works brilliantly.

I too have a Field Test K2 S/N 00020 that is fully upgraded and tuned.
It has all options except the KPA100 installed. It also has the now
unavailable K2XV transceiver interface and a Keyout Jack on the rear
panel. Functionally it is equal to a newly built K2 plus options that
are now longer

Hello,
After almost 18 years, my workhorse the Elecraft ATU T1 stopped working:
- I used it continuously with max. 10w usually 2-5 watts.
- I broadcast on the 40, 30, 20m and sometimes 80m bands.
- When I press the "Tune" button, there are no LEDs.
- The other modes do not work either.

Selling my K4D. I‘m the original owner and purchased from Elecraft 3 months
ago. Radio is in like new condition and has no issues. Have factory shipping
box and manual. Asking $5100 shipped CONUS.
Please contact me off list with any questions/request for photos, etc.

With a K4D diversity operation is easier than it was with the K3, as you
can swap the auxiliary antenna between the main RX and 2nd RX with the
press of a button (no cable swapping in the case).
For many years I have used a simple active antenna alongside my main
antennas. By using a horizontal ma
