[Elecraft] [XV144] Local Oscillator Power Control

[Mike Lewis]

My answers inline ...

>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.
