Hi Kx3 users,
Other posts have previously dealt with the issue that the standard KXUSB
cable for Kx3 does not support CW keying from the computer to the Kx3
radio, simply from the fact that as opposed to the ordinary serial
connection (old RS-232 standard), the RTS and CTS pins are not

Hi there.
I'm really liking the ATU in my KX3: it is able to solve all the bands
on my antenna (a G5RV) to a perfect 1.0-1 match, with the exception of
160 meters. It can only get that down to 7.5-1 (or so).
I'm curious as to what the maximum SWR is, that I can safely transmit
at, without
Selling as new - used twice and decided I prefer a digital readout. Unit is
perfect and works as intended.
Price is $170 (online price is about $200) This unit handles 1-125 watts

Seems to me Elecraft already has a great linear DC supply:

It is too late to add a 13.8VDC aux supply to the KPA-500, and besides, I don't
know if it has an internal supply with appreciable current capability
I had this happen to me during mobile operations and not sure why either.

Sometimes this can happen because of ground current with the antenna

SPE has some misconception that their ALC is fast enough that the

If you want to use the XG3 with a USB port you'll need to order the KXUSB

The point is not to widen the SSB but to use the FM crystal filter to limit

This in-band noise pedestal could be 20-30 dB above the normal
