Collins Mechanical Filter ID.
I am restoring a 1937 BC-312.
A previous owner had installed a Collins mechanical filter in the 1st detector stage (normally a coil with crystal phasing). The Collins filter is part number 526-9395-00 and labelled "F 455 Z 7" From google searches, it appears that this might be an SSB filter, but I haven't found an exact reference. Anyone know what this really is? I have to decide whether to "un-modify" this stage or leave it as-is. TIA, Steve. -- Steven D. Swift, , http://www.novatech-instr.com NOVATECH INSTRUMENTS, INC. P.O.
