Hi,

I decided to open up this military transceiver which a tenant
left about a decade ago -- during the non-pc days of s. africa.

It looks as if it was for a tank or armoured car. Made by Barlows.
2 units SO/53 and VS/57 which strap into a base unit: the
power distributor B57.

It's 30 - 40 Hz steppable.

Q1. Is this one of the military frequencies ?

The SO/53 unit has 7 internal cans: Tx, VCO, TLT, Audio, IF, I.C.,Front End.

Q2. what are TLT and I.C. ?

Sounds like I.C. is InterCom. The rest is beyond me at this point. Do
please let us know what it all is, once you find out.
