• BTA-250L Broadcast Transmitter is a complete, self-contained unit that will provide reliable, high-fidelity operation at any frequency within the range of 540 and 1600 kc. Excellent frequency stability is attained by the use of a crystal contained in a temperature-controlled chamber in the oscillator circuit. No greater deviation than +/- 10 cycles from the assigned operating frequency is pemitted. Contribued by Scott Todd. 29M
• BTA-250M Broadcast Transmitter is a complete, self-contained unit that provides a power output of 250 watts at any frequency in the 535 to 1620 kilocycle range. Mounted in a single RCA Type BR-84 steel cabinet, the unit utilizes a temperature-controlled crystal for close regulation of the operating frequency. Contributed by Scott Todd. 8.6M
