Judging by my recent transaction, $600 is way too high.
Last month, I purchased an XV144 and an XV432 transverter in 'as new’
condition. The only things that were missing was any cables and manuals - which
are available to download from Elecraft. Including shipping from the USA to the
UK, taxes
Yup.

Ron and all,
The XV144 will not tune high enough in the 2m band to send FM. The
28MHz IF strip is not wide enough to do that with one Local Oscillator
crystal.
The K144XV switches crystals to allow the upper half of the 144 MHz band
to be tuned.

David,
First - those diodes across the relays do not control anything, they are
there only to absorb the reverse polarity voltage kickback when the
relay opens. That means when a relay is active, you will have 12 volts
on the cathode and close to zero on the anode. So K4 is activated, but

Hi Don,
I had to order some resistors on line, got a box of them now. I am still
not getting the voltage that I should be getting. I check for 12R voltage
at the top of R16 and C29 and see nothing. 12R voltage comes from the K5
relay.
I check the run between K5 to R16 it looks good.
David,
If you found zero volts at D3, then R12 is not fully soldered. OTOH, if
you found close to 12 volts, D3 is not doing its job.
Good luck on finding parts at RS if it is anything like the store in my
area.

Yes, you should read 6.8 volts to ground at the C4 D3 junction.
Make certain you have voltage at both ends of R15. If you do, then

The exact voltage at TP5 is not critical at this stage of alignment, it
