|The 53 Set Transmitter
There is more to this HF transmitter
than I have, namely the modulator and power supply.
The unit pictured has
the PA stages with 3 large roller coasters and a couple of 813's.
is the separate slide in unit with the large dial.
This one is in mint
condition never having been used, one day I shall find the other
bits, power it up and dim the lights in Mullion Cove.
The complete transmitter should look
like the one below right, the unit on top I believe is the ATU.
other photographs are of my own equipment, but as I do not have a complete
set the image to the right is not mine
|The photo to the right taken in the
1950s shows how not to service a 53 set, it was kindly supplied by Mr
Brian operated and serviced this radio transmitter as well as the 19 set
AR88 and others.
Bian is the good looking fellow on the left with
the fire extinguisher.
Update from Brian
Just for info. - The grease gun was a fire extinguisher and the other two were:- Sam Blake and 'Lofty' Manners.
Sam, who lived in Chorlton-cum-Hardy, Manchester, died a couple of years ago but I haven't any info on 'Lofty' Manners apart from the facts that he was a Nat. Serviceman and came from the West Country.
The three of us served in Gurkha Royal Signals (now the Queens Gurkha Signals) and the photoraph was taken in the transmitter site at Rasah Camp,
The camp being the HQ of the 17th Gurkha Infantry Division. (1955).
