Circuit to interface Icom706 to the Ameritron AL-8

[WB5OVQ]

Can anyone tell of a relay circuit to interface the IC706 to the Ameritron?

Use pins 2 & 7 of the 15-pin ACC connector on the rear panel of the Icom, with pin 2 being ground (chassis) and pin 7 being the AMP KEY line that connects to the center pin of the AL-80 RCA phono jack.

Isn't this clearly shown on page 6 of the Icom manual?

No, WIK, you cannot key an amp from a 706 like this.  You HAFTA use an external relay on most amps.   And, when you post a .pdf link like this, most of us cannot "save" it on our machines.  You need to post  the webpage, and then right click and select "save target as"

I agree with W7DJM.

If you try to key that amp with the wimpy
little transistor circuit in the 706 you are
just BEGGING for a pile of VERY costly repairs.
You can build your own little interface out of
a 9 volt battery and a reed relay from Radio Shack for
a few bucks. Or, if you're lazy or a No Coder you can buy one of those MFJ interfaces, I think they are the
ARB 704 or soemthing. Don't qoute me,
look up the exact model number.
On E-Bay they also sell 706 to Amp Interface cables with the reed relay already built into the DIN plug.
I think that they are about $25 to $30 USD.

PLEASE, PLEASE, PLEASE DO NOT DO THIS THING!!!
