Description
The Icom IC-751 is an advanced transceiver covering 160 to 10 meters
It features a high performance 100 kHz to 30 MHz general coverage receiver built in. Output is 10 to 100 watts SSB/CW/RTTY modes (10 to 40 watts AM). The IC-751 has sophisticated capabilities such as: dual digital VFOs, all-mode squelch, Notch, Passband Tuning, RIT/XIT, pre-amp and attenuator. You also get 32 memories. The two color fluorescent digital display is easy to read. There is a multi-function meter. Serious CW operators will appreciate the full and semi break-in capability. The IC-751 has a high quality FL-44A 500 Hz SSB filter. The rear panel has an SO-239 antenna jack plus a receive only RCA phono jack. This radio requires 13.8 VDC at 20 Amps. 12 x 4.5 x 14 inches (306x115x349 mm). This radio comes with the HM-12 hand mic. The IC-751 was replaced by the Icom IC-751A.
