Allied Radio's model L-2754 transceiver had a superhet receiver tunable from 50–54 MHz and a 7 -watt, crystal-controlled AM transmitter. The 115 VAC power supply was self-contained, and both 6 and 12 VDC supplies were available.
This is exactly the same device as the United Scientific DeWald 6 meter transceiver (see separate entry), and the Lafayette HE-35.
Specifications & Features
– Input power: 7 watts
– Features a front-panel crystal socket accepting 3rd overtone crystals above 50.1 Mc (normally supplied with a 50.2 Mc crystal installed).
– Utilizes a variable "Pi" network for matching to various antenna types.
†he receiver is a superheterodyne circuit preceded by an RF stage for improved sensitivity, selectivity, and reduced RF radiation. Includes AVC and a controlled noise limiter circuit. Built-in series-resonant and parallel-resonant TVI traps are designed to suppress television interference on transmit and receive.
