I am thinking of building a low power QRP valve transmitter (e.g. 1 or
perhaps 2 6V6's/6L6's) for use in the G-QRP club valve activation weekends -
output 5 to 10W.
Many of such circuits are using a crystal oscillator, but I plan to build a
Nano digital VFO in place of the crystal to have more fr
Thanks Fred for the suggestion of using a Dow-Key relay, but they seem to be
unavailable in UK/Europe except on Ebay secondhand for $120 or more & those
are mostly 24V rather than 12V.
Are there any alternatives

I am using the K2 on CW with another XCVR and I need to mute, or vastly
reduce the system gain. Does anyone know of a good scheme to do so? AGC?
Mute function? Thanks, Bob

There is a Dow-Key coax relay that does that automatically ... a pin

Ray,
For what it's worth, I've been running a homebrew solid-state QSK CW
transmitter for the past 4 years. My T/R relay is an AXICOM V23105A5303A201. It
is a dual SPDT relay where each SPDT section is tied in parallel for greater
power handling capability. The receiver is connected to the ant
This might be helpful to you.

Hi, Bob-
I don't know if this applies to your situation, or if it is the best
available scheme really, but I use my K2 for RX when I am operating with my
Johnson Ranger TX. The best way I have found to do this is to key both in
parallel, the K2 in TEST mode so that it mutes RX in synch with m
