VFO stability question
 

hi:

i see a lot of transmitter schems where the VFO's power is switched with
the mic or key. and i saw a test where it took 5 minutes of warm up time
for a VFO to stabilize.

now, of course a good op will be checking to make sure he's on freq.,
but aside from reduced current drain on batteries, are there other good
reasons to switch the VFO providing it's not leaking into other parts of
the rig (if it's a tranceiver) and wreaking havoc?

yeah, this is for a homebrew project. as much as i like the idea of
powering down the VFO when it's not needed ...

thanks in advance for any info on this.
