THE COLLINS 30FXB TRANSMITTER

Introduced in November 1934, the 30FXB was a floor-standing, 100 watt phone and cw transmitter that likey was designed to replace the aging 150 series. The November '34 QST ad stated:

"Its ultramodern dress will lend an air of distinction to anybody's library. Yet its beauty is entirely functional. Every detail is neat and graceful because it is designed for efficiency. Years of engineering experience and gift for design enter into its construction."

The 30FXB was rated at 100 watts output over the range of 1500 to 15,000 kHz. The unit was crystal controlled and used a 203A in the final, modulated by a pair of 830Bs. Fixed neutralization was used.

A 7C high fidelity speech amplifier (frequency response 30-12,000 Hz) was included as an integral part of the equipment, as was the 2C pi antenna matching network.

The 30FXB measured 55"H x 19.25"W x 12"D.

The 30FXB was replaced by the 30FXC in 1936.
