[Icom] IC-756 ProII carrier (how to get one?)

Tue, 15 Oct 2002 00:06:49 -0700

Hi Clete,

If the external device plugs only into the 4-pin Molex socket on the rear
panel of the radio, it emulates a coupler such as the AH-3 or AH-4. The
radio's coupler control logic limits the power output to 10W during the
tuning cycle. As far as I am aware, the exciter transmits at the virtual
carrier frequency during tuning. The coupler switches a 10dB attenuator into
the signal path to minimise interference.

Please refer to the following site for a detailed description of AH-4
operation.

The little external device uses the ALC lead to adjust the
carrier level to some predetermined value during tuning.
The one I built for my TS-940 also keyes the carrier on.
If the transceiver has a built-in tuner the odds are that
its "tune" lead will also control the frequency of the
carrier so that it is the indicated dial frequency, and
will not annoy others on a SSB net.    73  Clete
