I got some info :
The RT-34/APS-13 is a low power UHF tail warning radar transmitter/receiver which was used in Allied aeroplanes such as the P51 Mustang and also the P-38L, P-47D, P-61, P-63, P-82D in the later stages of the war.
The equipment operates at 420 MHz with a receiver IF of 30 MHz and is powered by an internal rotary generator which is supplied from the aircraft 27V dc system.
The electro-mechanical construction is all aluminium, and the equipment uses all miniature glass valves except for the voltage stabiliser which is a VR105V (0C3). The PA is two 6J6s.
Three modified APS-13 were employed as the primary radar altimeter fuse in the
