[ARC5] Fwd: Mystery Coils

[Robert Downs]

Wayne,

 

They are probably Antenna coils for the BC-611 and BC-721 radios.  I will have to do some digging to confirm that as the same coil form was used for the antenna coils in the BC-746 for the BC-745 Pogo Stick.  Had you included a side view photo I could say for sure.  The Pogo Stick coils mostly used SCC insulated wire while the BC-611/721 used enamel insulated wire.

 

I would have to look up the range but at least in the BC-611, each antenna coil covered 200 KC if memory serves.  Early production had a single frequency stamped on the coils so that there was less likelihood of poorly trained personnel using the wrong coils. Later production had the range printed on the side and/or end.

Does anyone recognize these?  About 2 inches long including the 3 pins on the bottoms, about .75 inch outside diameter. Built in coil forms embossed 32A28963 on the bottom.Both have labels on the top.  

One says ANTENNA 3525 KC 24K47591.

One says ANTENNA 3825 KC 24K35994.

I'm attaching pictures but I know some of the groups don't pass pictures through, so if you think you might want to see them but didn't get them via a group, email me & I'll send.

 

Thanks!
