Audio interface for the Icom IC756ProII

Today I spent some time modifying the audio interface that I used to use with my Icom IC706MKIIG, so that it would work with the IC756ProII. I removed the 13pin DIN and replaced with with an 8 pin microphone plug. Unfortunately I didn’t’ have much cable so I had to make do with what I had. The box contains two 6.5mm phono sockets wired up to the microphone plug. One socket is for PTT, the other for audio. PTT is operated via foot switch. It is important when setting up something like this, that you adjust the microphone gain, and mixer so that your ALC is as per the manufacturer’s recommended settings.

Bio

G’day

I first became involved in HF radio at the age of 16 when I sat for my 3rd class certificate in radio telephony (coast guard). I then became active in the CB scene of the late 70’s. I built my own 4 element cubical quad and other antennas at that time.

In 1979 I first attempted to study for my novice amateur operators license- unfortunately life intervened and I never did complete it.

I later became involved in HF radio via my role as a remote area 4wd tour operator, which rekindled my interest.

I completed my foundation license in July 2008 and was on the air as an amateur radio operator at last. Since then I’ve completed standard call (VK4MDX) and finally Advanced (VK4KIM / VK2KMI).
Details of my equipment etc are available from the links below.

I, once again run a business specialising in remote area 4wd tag-along tours and driver training particularly 4WD, off-road, particularly for mining and exploration. I also conduct towing training, teaching people to tow vans and trailers for work and recreation.

I’m a keen competition glider pilot and GA pilot. My other interests are 4wding, soaring and photography, human rights, technology.
