Fuchs MRV-1 VHF transceiver

At first glance I'd say this is an aircraft band AM transceiver.

Fuchs Electronics
MRV-1 VHF Transceiver
Frequency 118-149.950MHz
Channel Spacing 50kHz
Power Output 25Watts
Serial No 640

640 is a rather high serial number for a local radio, they made quite a few of these.

The top lid comes off, showing six removable boxes, a heatsink and some wiring. There's a tool clipped to the lid that's used to remove the modules.

Module #1, serial 099. The foam they used is not as acid free as one would like. It's disintegrating and harming the electronics. Some cleanup required.

This is obviously the IF, at 3.5 MHz which is rather low for a VHF rig. There's also a Torotel audio band-pass filter.

Module #2, serial 001 (!).

Module #3, serial 583.

Module #4, serial 449.

Module #5, serial 895. engraved "osc"

Module #6, serial 088.

The hour meter reads 1666, for what it's worth.

ZS-NTE, a 1943 Shackleton, was the first aircraft to be fitted with this type of radio (1984).
