Icom AH-705 Automatic tuner for IC-705

It fits perfectly with the LC-192 backpack, which has a compartment for the transceiver on the top. So you always have everything together. The power supply of the AH-705 is via built-in alkaline batteries (2 pieces of 'AA' or 'LR6' size) or via an external 12V power supply. Current consumption is approximately 1 mA at rest and approximately 300 mA during tuning. As usual with tuners automatic, once found the tuning steps are stored in a memory internal.

Dipoles or terminal wires, but also vertical, are possible as antennas agree that they should be operated a little out of resonance. The operation on the 160 m band requires an antenna with at least 30 m length, on the bands from 80 m an antenna with at least 8 m length is recommended. The tuner can be used on frequencies from 1.8 to 54 MHz. For tuning it is A power of approximately 5 W is required, maximum transmission power 10 W
