Green house photo comments ex Robert Milne who was there in
 1962/3

Pic1
Don't know PA tube - Robert responsible for store - he may know.
Was it a twin triode?
Built about 1940 now 1960 - old technology.
Power transformers at bottom.
Red and green buttons above rectifiers window are filament and
 HT on/off controls.
6 channels on TX each 12 all together 500W?
Panel below final contains multipliers which were modified (just
 before Robert got there?) to avoid interfering with TV.
Supposed to record meter readings twice daily but became lax
 about it.
Very reliable.
The two transmitter outputs were combined (in jigamaroos)
 outside the building and fed to the TX rhombic on open wire
 line.

Pic2
Two receivers fed with two coaxes from Nut preamps.
Signal generator below patch panel fed a dipole on the Nut to
 test receivers daily.
Key switch on third rack switched betweeen high and low gain
 RX preamps on Nut.
2 rhombics Tx ans RX.
Four sets of old fashioned carrier equipment - three channels
 each rack.
Automatic gain switching on these racks?

Pic3
Other side of room.
Speakers to talk to Tanebryn?
There was an audio oscillator and D & N set.
Patch panel.
MDF where lines came in with fuses.
Push buttons below box with meter? on it remote TX power
 control - usual operation from here.
Sig gen borrowed by Rex? to fix TV sets.

Robert says there were three main rooms - generator room,
 transmitter room and main/RX control room.   Perhaps another
 room next to motor room.   Plus toilet and lunch room.
Metal across windows for protection during war.
Hours of operation 9am to 10pm.   Two shifts.
There was a link to Robbins? Island as well.   He was slack
 paying his bill so the telephonist would only connect him
 to the post-master!
Cable station operated all the time - it was sideband.
