The transmitter was originally designed back in the mid 1930's. Used a quad of 204A's in p-p parallel, modulated by a pair of 849's. Later, changed to 833A's in pushpull modulated by another pair. Later version used parallel tubes in final. This was the standard RCA 1 KW for years. Triode were later superseded with 4-400's modulated by another pair in class AB1.

The 1 MX was replaced by the BTA 1R series with 4-400's. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
