Ah 4 Control Cable

broken image


Dec 16, 2012 AH-4 control extension cable is 50' of 18/5 solid copper sprinkler wire with UV resistant jacket (Home Depot $16.50) Connectors are 4 pin female mic and 4 pin polarized Molex male (Radio shack #274-224 $2.50) I used mic connectors due to the narrower width so that they could easily be fed through the wall from the shack.

  1. The AH -4 is intended to be used with certain late -model Icom radios, such as the IC -706 and IC -746. The AH -4 communicates with the radios using t wo control lines.
  2. If you are using this cable with the IC-718, be sure to set the tuner menu to '4'. The LDG tuner and interface cable emulates the Icom-AH-4 tuner. Price – $10.00 US.

    Black: GND

Tuning Process

  1. Put about 10 watts of power into tuner. ( CW )
  2. After about 0.5 second, press start switch for a moment. ( use momentary contact switch )
  3. LED start blinking , which indicate tuning is in process.
  4. After about 3 seconds or so, LED shut off, and tuning is completed,

If tuning is successful SWR should be less than 1.2

Some radio start to reduce the power when SWR is high, this tuner takes at least 10 watts of power for tuner to work properly. Most of the 100 watts radio should not have any problem, since they still put out 10 watts or so, even with high SWR.

But, it does not work with some QRP radio ( 5 watts or less ).

Adjust power level, if necessary.

You may extend control cable to 100 feet , it still work fine, you can put this tuner on top of tower.
