Hi Chris
Thats a good point! its very heavy all steel construction so as you say
probably Land based, I have tried to GDO the front end coils, and get a
good dip on the RF and Osc coils around 38 mhz, The antenna coil I
can't find a dip although the coils look very similar in all three
stages, So what would a fairly high gain fairly fixed freq receiver be
doing on a military airfield during WW2 with a VR138 in it?
By the way I noticed there is also a valve diode base in the front end
similar to an EA50 type I would think and another at the end of the IF
chain

Hi Chris
My mistake the other valve is a VR136 not VR138 the unit is a bit
tarnished, strange that transmitting valve is there? I can't believe
its a transmitter, or transmits in any way, there is no change over and
the controls and connections are real simplicity, it looks like a
straightforward simple HF receiver? Anyway thanks for the info, I guess
by the lack of replies its an unusual one

VR136 is another B9G base, and is an EF54, again with a maximum operating
frequency of 300MHz.

I'll have to dig out my Yeeha! password and have a look at the photo.

One thought: if it's steel-cased it's probably ground based kit, as most
of the airborne stuff was aluminium to save weight.
