[Ron D'Eau Claire]

The L.O. does stay powered up when you are on other bands. All power is
removed only when you shut the K2 off. 

Unless you are using separate Tx and Rx antennas, you have an antenna
switching relay attenuating signals at the front end as well as the relays
at the I.F. port. (A relay was used for antenna switching to maintain the
best-possible noise figure). 

I am not sure whether the mixer and RF preamp, etc., are active when you
select other bands.

If I daisy chain three XV transverters with my K2/100, and I have the XV50
selected, change bands to the XV144, and then return to the XV50, does the
XV50 get turned off completely while I am using the XV144?  In particular, 
does the local oscillator power down while I'm on the other band?  Or do 
just the downconvert sections shut down?  Or is just that relays route the 
RF to the correct transverter while all the transverters are still powered
up?

For VHF contesting, where you might be switching bands very frequently, it
would be a major pain to have the local oscillator power cycling all the
time.
On the other hand, you don't necessarily want your 222.100 transverter
and 432.100 transverter downconvert sections both running with just a relay
between them - there will be bleed through on strong signals.  Downeast 
Microwave transverters have the ability to turn their downconvert sections
on and off while leaving the local oscillator on - which may be what the XV
series transverters do with their switching, but it's hard to tell from 
the manual....
