Time To Mount The Antenna Tuner, Ok I used scotch bright pads with a right
angel die grinder to remove the paint off the bottom of the SGC-237 (No
Photo) because if you have not guessed it by now we are using the aluminum
sheet as a ground for this project. A good ground with a wire antenna is
key for this set up.

Still have some wiring to do for main power and 14 Volt and 24 Volt, Need to
wire an 8pin connector under the power for remote mount control head...
Depending on if the junk store is open or not Monday I should have it done
and ready to test. May have to D sub the Control Head. really want to use a
8pin round connector similar to the power.
BBL...
Called norvac and ordered the rest of the parts today... so it's drive 40 miles
round trip traffic and snow or pay $8.00 for shipping should be here tomorrow.

The $50.00 remote separation cable is an 8 conductor cable so I ordered P700 And
T700 microphone connectors,

http://internationalferryflights.com/HF_BOX/2399.jpg
&http://internationalferryflights.com/HF_BOX/micplugz.jpg

Possible mount under the handle or below the power cable.

Tasks today is the External fan nod to the radio to help with cooling,

Instructions here,http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=10087

Will finish 98% of the wiring for 28V/14v system,

Wire Tune Locked LED to case

Make a fee ground straps.

Clean up kitchen table, prepare for finial assembly & testing.

Wire roof with coper wire and coax for testing, And why dose it have to
snow/rain every time I get on the roof?- Hide quoted text -

- Show quoted text -

What do you need the microphone connectors for?

Is there a way to somehow plug the microphone cable/plug of a standard
aviation headset into the transceiver?

Thanks,
Gerd


Microphone connectors are for the separation cable for the control head.

I already have built an adapter to use a standard aviation headset that plugs in to the control head.
