Don't you guys have anything better to do than nit pick over a
negligible warm up drift. I don't think that you will be planning to
do any ARRL Frequency Measurement Tests, within the first 10 minutes
of your K3 turn on !
I have bought several 10 MHz DOUBLE Oven Controlled Crystal
Oscillator
I have a "ON STAGE KSP100 Universal Sustain Pedal" that I got from
Amazon for $17.99 ($25.97 inc. tax and shipping). If you are Amazon
Prime will be $6 less.
It is very well built, comes with a 1/4" plug on the end of the 6'
cable, and has a switch to select either NO to NC. It works great,
No, I don't think so, Ken. There are plenty of frequency standards
already available. In any case, we would not want to direct Elecraft's
attention away from developing the K4 ;-)
Your suggestion of putting it in the P3 box is not practical. You make
the assumption that everyone that has a K3 also
IMHO the best foot switch for radio use is the M-gear SP-2. Takes very little
effort to depress and has a switch to select NO or NC connection.
I have 4 of them and know others that I’ve recommended them too and have not
heard of a single failure.

There appears to be interest in external frequency standards to enhance the
already outstanding stability of the K3.
Would an Elecraft accessory that uses the clocking from the GPS system be a
viable product? Perhaps hidden away in the P3 cabinet if there isn't
suffucient space in a "loaded" K3.
Maybe my concept is wrong but I do not see the need to leave a GPSDO on. Once
the GPSDO locks to the satellite it is all that is required. I have decent sky
view and it locks up using multiple satellites quite quickly. So before the K3
has warmed up the GPSDO has locked and I'm locked to it.
T
Ed, you restate the problem and a simple solution but quite apart from the
cost (which is trivial or not depending on your circumstances) we should
all, in my view, be trying not to use energy unnecessarily in the interests
of our grandchildren. There is also a potential fire risk with a unit th
Folks let me set a few things straight. I have designed a few high stability
time bases and I have done the lab work so I am confident of my facts.
First, you never want to use AC or bimetal thermostats for precision oven
heaters because they are inherently noisy and ultimately unstable. Bimetal

I spent a lot of time over the past few years looking at this exact

Be very careful ... Signalink USB lacks sufficient bypassing on

Alan,
Lots of anwers have been given.
One more: Usually those electrets have 3,5 mm connectors. Use the back
panel as an entrance for the mic. No need for a front panel microphone plug.
Actually, I never used one with my K3. I have had several mics
connected to it, all with a 3,5mm connector.
