TR1196 and R1147
The Seafire also had different and additional R/T sets
presumably to allow ship-air communications and perhaps also some form of
homing device. These were the TR1196 and R1147 respectively.

Also
includes case and switch covers shown left
This is a unique opportunity to
purchase a IFF set up. This particular version is
the R3109 so likely to have been used on later mark Spitfire
and of course bombers. Outwardly the same unit as the R3108
just different voltages. Not sure about dates but most
likely around 1942/43 as the following extract talks about
USAAF/RAF intercommunications.
This set includes, Remote
contactor 24Volt boxed mint condition. Reproduction case
which houses the IFF destruction buttons found in the
cockpit of the Spitfire on the RHS. Two original IFF button
covers for the case. The control box for the IFF mounted in
the rear fusilarge, the IFF reciver R3109 with its internal
parts intact and finally the clockwork mecanism.
Seen under location of the
IFF case which contains the destruction trigger buttons.

1 Jan 1940 - The RAF
introduces Identification Friend or Foe (IFF) signals to
help identify Bomber, Coastal and Fighter Command aircraft
on radar screens.
An IFF system acts as a radio
transmitter and receiver. It sends out continual radio
signals made up of coded pulses. A friendly IFF system
will recognize these codes when it receives them and will
transmit further coded pulses which identify the aircraft
to the interrogating IFF set.
IFF Mark II was developed to
cope with the additional frequency bands of newer radars,
and covered these in three swept ranges, including the
original IFF MK I band. However, radars were advancing at
such a rate that IFF MK II soon did not cover the
frequencies in use so variations were produced for other
radar bands, such as the IFF MK IIG and MK IIN which were
British sets for UK radars, and the USA SCR-535 (ABE) and
SCR-535-A which worked with the early US Army radars such
as the SCR-268, SCR-270, SCR-271 and SCR-516. The US Navy
ABE and ABK sets worked with naval radars.
The IFF MK II was designed to
allow switching between any one of 6 different coded
responses, usually specified for various types of mission.
However, in practice it proved difficult to distinguish
one echo from another so generally only position 1 (or A)
was used, whilst the longest, widest response position was
used universally as a distress signal.
In order to respond to the
growing number of radars in service the aircraft or ship
often had to carry multiple IFF units. The services
recognised that with the proliferation of radar and other
equipment there was a need for a distinct frequency band
for IFF with a common equipment specification. They chose
the 157-187 Mhz band.

Battle of Britain Spitfire radio TR1133 (pg3 rad)
This is the
Holy Grail of WWII Radios. Its
an original TR1133. This radio was only fitted to Spitfire's
and Hurricane's for a short period during the Battle of
Britain. It was replaced soon after by the TR 1143 and
TR 5043. I am also including the rare Dyno that power's this
set. The dyno and radio appears to be in good order
internally and has a 12volt input as it should be with early
Fighters.
Michael
Clarke has this to say about the TR 1133.
TR1133
Some time during the Battle of Britain
the RAF
introduced a VHF set into the Spitfire. This was the TR1133. When a VHF
set was fitted the aerial was removed leaving the aerial mast alone to transmit
and receive signals. I have never seen a TR1133, or a picture of one, but I
believe they used the push-button type controller with a ‘Jones Plug’ type
connector at the back. In fact I think ‘Jones’ connectors were used throughout
the installation.
I understand that Spitfire Mod 385 introduced the TR1143
in lieu of the TR1133. This was in the middle of 1941.

DF Loop aerial control box(pg3 rad)

This control box dates from
the early war. It was used to physically rotate the DF
aerial loop in Bombers like the Wellington by means of a
flexible cable drive. Supplied to the RAF by the US . There
is another example complete with its antenna listed in
previous radio pages. The DF loop aerial sits on top of the
fuselage just behind the cockpit. The cowling of the aerial
can be clearly see in this picture.

This is a radio tuner for
the early type radio sets as fitted to Seafires. It tunes to

fitted to the LHS of the cockpit. Its in relic condition
with part of the airframe and a cockpit lamp attached. The
handle is seized and will not turn. Great display piece.

received.

Spitfire Beam approach aerial (pg3 rad)
This aerial is a for the Beam
Approach it was used on Spitfires and no doubt other
aircraft of the period too. I think the beam approach stuff
was used as an option with the TR1133 or TR1143 setup - at
least the Spitfire Mk V manual seems to illustrate this. In
good condition.
