[Boatanchors] Unusual BC-221

[Dave Rossetti]

Interesting. Most BC-221 were originally battery powered and later converted with makeshift AC power supplies. Your's obviously was AC powered from the get-go. There were over 25 different different models made by a slew of different manufacturers for use during WW II. Few of them had a modulator. 

I have found the BC-221 to be a very useful while nostolgic piece of test equipment. As long as you have an idea as to roughly what frequency you are beating the signal agsinst (generally not a problem), it can be used to accurately tune transmitters and receivers to a specific frequency. It can even be used to align IF frequencies eliminating the need for a frequency counter and RF signal generator. 

Thanks for sharing.

</div>This unusual BC-221 followed me home from a hamfest a few years ago. The 
guy practically begged me to take it.

I just got it out of storage a few days ago.

I have never seen one like this and don't find any model numbers on it.

I did have it on the bench and it works.

Attached are some pictures.
