I came across a reference recently to WASHTUB in WWII and was looking
into this in Pawley and came across mention of a BBC project giving
advice on the provision of mobile long-wave transmitters for use by
Regional Commissioners if their area became cut off from central
government in the event of invasion.

Many aspects of Cold War planning evolved from WWII but I had never come across any mention before of "mobile long-wave transmitters".

Anyone know more?

For medium wave, the German army had mobile medium wave transmitters
with a mast high of 72m. Such a facility could be used for LW too.

Although, multiple LW sites exist in the UK, wasn't it an option to use
them with higher power?

AIUI these were what they used to broadcast Lord Haw-Haw's propaganda
towards us. The idea being they could move them around before we could
DF them and bomb them.

I doubt if a mobile MW transmitter would have put out enough power to be
heard clearly in England.

I tracked down where I got the idea from:

https://jonathanmarks.libsyn.com/media_network_wartime_deception_part_1

Absolutely fascinating, I'll be listening to the whole series.

I think there has been a bit of confusion about the 'Lord Haw-Haw'
broadcasts; the 31 metre band which he announced is not medium wave.
Mobile stations with relatively small aerials wouldn't be heard by the
average listener in England on medium wave, they would have to use a
much bigger aerial and earthing system which would take days to set up
and dismantle.

The very mobile stations with small portable aerials could only have
been effective on shortwave for distant broacasting or on medium wave
for local broadcasting.

Yes, I should have said, when I was searching for this I came to the conclusion that you were correct and that the person interviewed in
Wartime Deception part 1 was muddling up two different kinds of German propaganda broadcast. In fact other info I found suggests that:

A. The mobile transmitters were up to 20kW each, though three could be
used together to get 60kW, but that probably didn't happen often.

B. The mobile transmitters were used only for the false flag "black propaganda" broadcasts like "Workers' Challenge".

C. The Lord Haw Haw broadcasts, and probably the other "white
propaganda" broadcasts like "Home Sweet Home" and "Vision of Freedom"
that were aimed at the USA on short-wave were sent from normal fixed transmitters.
