FA-7 cooling fan is available. The transmitter section also features very low harmonic and spurious output, and is equipped with automatic high VSWR protection. VOX operation can be disabled by a front panel switch. The modular construction of the TR-7 reduces service time to a minimum. Each module is designed to perform a specific function, and this feature, combined with the open, accessible layout of the transceiver greatly simplifies any required alignment and troubleshooting.
Liberal use is made of table connectors, simplifying module removal.
Less than 150 Hz per hour drift after first hour. Less than 5 dB output variation for 100 dB input signal change, referenced to AGC threshold. Greater than 0 dBm. 50 dB, minimum.
