PP selling a lot of stuff from BBC Cardiff, Lots of tables and chairs etc. but in there is:
Lot 2371
3x Xicom TWTA travelling wave tube amplifiers (spares or repair)
|
No picture, no type No.! I think there is a spectrum analyser in there somewhere as well.

Yep saw those, made a few phone calls .. won't be bidding.

Ive seen similar in Outside Broadcast vehicles in the past.
I think Cardiff may have had uplink capability from the Studio,
Glasgow did if i recall
These are typically 300W+ satellite uplinks operation about
14GHz The part no. confirms this and there is a manual online. I
know there were 100W and 200W variants of the rooftop versions
They probably will not work on 3cm
without some modification. They have almost certainly got a waffle
plate output filter to protect the downlink band (My version is
the rooftop waterproof type and has this fitted, it is
essential). Powering up with 10368 drive unmodified is likely
to cause at bets a trip at worst permanent damage
If they have been in OB units they will be well used and 'all
shook up' though that in itself shouldn't break them
Spares or repairs is always worrying.. Trust on the D type
shells suggest that these have not been well cared for and have
got damp.. EHT and damp are not good bedfellows
Forced air cooled
These should carry a health warning. 300W of 10GHz is
hazardous and even leaky flanges may be an issue.
Great for serious EME operation, not so good for terrestrial. I
run 50W terrestrial and it make me a bit of an alligator. All
mouth and no ears
If the price doest go silly I may bid, literally for spares.

Lot 2141 is the OB van with the roof mounted units ... the info I had was that the ones on the vehicle are known to work, but the remote control has been removed from the vehicle and sent to news facilities in London.

Link if interested. There are two units on the roof, I'm tempted if the price does not go silly ...

It's a very popular van for small load courier services and they sell for silly money, the engine alone is worth quite a bit more than the current bid.

The info I had was that it was unlikely to pass an MOT by quite some margin, it should still have the generator in the back though, which is a nice 3 cylinder Kubota usually, in a "Panda" box ...
