TBX-4 to BC-611 Radio Contact 2009

This video was taken at a Military Radio Collectors Association mini-meet at former Signal Corps Fort Monmouth E Evans Signal Lab in Belmar, NJ, now the InfoAge science and history museum. N3FRQ, K4CHE, and K2WI gathered to activate a number of sets and demonstrate them to visitors to InfoAge and the New Jersey Antique Radio Club Radio Technology Museum.

As pictured, the TBX-4 receiver is running on batteries in the battery box under the radio unit. A pair of 2V rechargeable cells light the filaments, camera batteries provide bias, and a large string of 9V batteries provides B+ and screen voltages. The transmitter was running on an EJ-4 dynamotor and 12V storage battery not pictured. Hand generator pictured on sign post. Maybe next time we'll find someone less than 30 years from basic training to crank it. Received audio presented with a loudspeaker and 600-ohm to 8-ohm transformer.

The base of the "flagelliform" 24-foot vertical on the right, with its bag behind the set. Leads for it constructed with old-style spark plug terminals and spark plug wire I got at an engine show.

Breck and his 611 are behind the ARC-1 display on the table behind the TBX.

That has to be a world record for distance... (SHORT distance) - but seriously - very cool to see those old radios in action.
