(4.4/5) Add a review / View all reviews

Desktop Shortwave Transceiver

The ICOM IC-745 was an advanced transceiver for its day, covering 160 to 10 meters. It has general coverage reception ranging from 100 kHz to 30 MHz. Frequency stability is made possible by the utilization of a Temperature Controlled Crystal Oscillator (TCXO) offering less than + or - 500Hz after switch on from 1 to 60 minutes, and less than + or - 100Hz after 1 hour. Less than + or - 1KHz in the range of -10 degrees C to approimately +60 degrees C. Output is selectable between 10 and 100 watts in SSB, CW and RTTY (digital) modes. The 745 has "sophisticated" capabilities such as: multi-function meter dual digital VFOs, all-mode squelch, Notch, Passband Tuning, RIT/XIT and attenuator. 16 memories are built-in. Tuning is done using increments of 1kHz, 50Hz or 10Hz. The flourescent digital display is easy to read.
