ICOM IC-728 Transceiver 100W

Description

CAUTION TO TRANSMIT TO AM/FM You need the optional
Icom ui-7 unit installed
read the description (
AM/FM with UI-7 option
)
The high transport costs (50$) are because of 5 kilograms (

The
Icom IC-728
covers all 9 ham bands for TX 160 to 10 meters. There is a triple conversion 500 kHz to 30 MHz general coverage receiver built in. Output is 10 to 100 watts SSB/CW or 10 to 40 watts AM. Whether you are a beginner looking for that first rig or an "Old Timer" after another HF transceiver, you are sure to appreciate all of the quality features needed for smooth, reliable communications. Comes with a built-in 10 dB pre-amp, a 20 dB attenuator. Enjoy 26 memories and three types of scanning. Includes HM-12 hand-mic. This radio requires 13.8 VDC at 20 amps. The rear panel
has SO-239 antenna input and other I/O jacks
