[ARC5] CBY-52232 On 160 meters

[Brian Clarke]

Hello Ken,

The thought of rewinding the VFO and PA coils alone would put me off 
such a project. To get that set to resonate in the 160 m band, you would 
need about 2x the inductance, ie, about 1.4x the number of turns - the 
variable capacitors are the same throughout the whole Command family, 
AFAIR. You may be able to get away with a little judicious changing of 
padders to get you there - tracking may not be that wonderful - but then, 
the 160 m band is not that wide. If you can find the Tx that covers 1.3 
to 2.1 mcs, you will have no major reconstruction to do. 

It will also help if you have the appropriate rack into which to plug the 
Tx, rather than soldering to the sockets on the back; I can supply such 
a rack, NIOB.

Before firing up, check the capacitors, as Robert has advised.  For my 
own peace of mind, I would also check the insulation of the HV wiring 
- the early sets had cloth over rubber - the rubber has by now perished 
down to a black carbon mess that is more conductive than you would 
like. The later sets used an early form of PVC insulation that is also 
rather suspect - the solvent squishes out leaving a tacky mess whose 
insulation is unknown. 

And, if you don't already have one, get a licence.
