How do you manage the 'Local Oscillator Power Control'?
I configure to remain on at all times.
And do you have the XVOVN (crystal oven)?
Yes
Of the 3 power control options, which do you use (JP9, 1-2, 2-3, 4-5)?
JP9 pins 4-5. My K2+transverters are mostly dedicated to VHF+ work, and is
always turned on monitoring local SSB activity and weekly 2M and 1296 SSB/CW
nets. The power draw is so low it is not worth turning off. I assigned the
squelch to the PF1 button to keep things quite and listen for random local
stations. Pins 2-3 might better suit you if you only occasionally use your
K2.
Do you have the oven?
Yes
Does anyone find they need to leave the oven on all the time to achieve
best stability?
Yes, mostly for reduced startup drift. The unit will create heat when you
start transmitting and get some drift. Especially important for digital
modes operation.
If the XV144 is not used that often, would it be better to turn the crystal
and the oven off when the XV144 is not in use?
I do not see any advantage to turning it off. My has stayed on its whole
life (had mine since they were first released, a couple years now). I use it
for rover & portable in VHF and Microwave contests also - temperature swings
are signifiicant in this usage. It doubles as a IF for my microwave
transverters with help from the KRC2 band decoder. There is a paper on my
web site for how I set up my portable contest station built around the K2.
It lists all the jumper positions and mods I used.
