[Boatanchors] Boatanchors BC 221 heresy

Hi Brian,

I would hold off scrapping/salvaging/organ harvesting those as long as 
you can. I thought about something similar for mine. The most useful 
parts are the tuning mechanism including the tuning cap to build a 
wonderful VFO. In fact, it already is a wonderful VFO. Replacing the 
wonderful VFO in a BC-221 or LM (I have LMs) with a DDS would be ideal. 
So my plan is to build a modern heterodyne frequency meter with all the 
capabilities of the LM (or it's little brother BC-221) with a DDS at the 
heart. I suspect due to tuning steps instead of continuously variable 
tuning there will still be a need for interpolation/extrapolation. But 
it should be quicker and easier. Building such a device can extend the 
concept of the LM and BC-221 another 100 years.

Since you are already admiring the DDS those wonderful VFO parts will 
not be much use to you. Museums need only so many. It is not looking 
good for all those heterodyne frequency meters. A moment of silence 
please. <head bowed>

Any interesting stuff hardware wise (electronics I doubt there is much), but if there is good variable gear stuff or whatnot I guess I might be wise to hold on to anything 'good and interesting'.
