[Milsurplus] BC-610 and 160 meters...and below...

[Kenneth G. Gordon]

The BC-610 in its normal configuration covers from 2 through 18 
Mhz.

There was a "conversion kit" which consisted of two tuning units, 
two final plate coils, and two vacuum capacitors which allowed the 
BC-610 to cover from 1500 to 2000 Khz and from 1000 to 1500 
Khz.

That below is taken from my "Instruction Book for Radio 
Transmitter BC-610-I", page 39, paragraph j.

"     j.  Frequency Conversion Kit MC-509. This kit is used to extend 
the transmitter frequency range to cover 1 to 2 mc. It consists of a 
chest containing three Transmitter Tuning Units TU-61, three 
Transmitter Tuning Units TU-62, two Coil Units C-454, two Coil 
Units C-455, two each 100- and 50-uuf plug-in vacuum capacitors, 
and equipment to build a half-wave antenna. For full details, 
including necessary changes to Antenna Tuning Unit BC-939-A,
