[Milsurplus] BC-611 Coil Info?

[WA5CAB--- via Milsurplus]

Robert,

I have well over a thousand 3885 KC antenna coils. $10 each plus shipping. 
I also have a few tank coils, and a few of the correct crystals. Same $10 
unit cost. Or $30 for a two coil, two crystal set.

Unfortunately, there aren't any 3880 KC crystal pairs around that I know 
of. You would have to get those made. Or you could try the old trick of 
rubbing graphite from a 2B pencil onto the blanks to lower them slightly.

However, if you do find the 3880 KC crystals, the tuning range of the 
antenna coils is 3825-4025 KC and of the tank coils is 3825-4225 KC. So almost 
anything in the 75 meter band is covered by the same coils. Exception might be 
if your chassis is heavily coated with MFP varnish, but that only affects 
the upper end (lowering it).
