IC-410PRO AF out on mic socket

Post by VK4GHZ » Sat Mar 21, 2020 9:35 am

An Icom IC-410PRO UHF transceiver is being interfaced via it's RJ-45 microphone connector to a Clear-Com intercom system via a TW-47.

Audio Out is required on the RJ-45 mic connector, but;

a) It doesn't appear there by default

b) the IC-410PRO Service Manual is unobtainium, so try finding the solder link to do that!

Hi Adam,

Just wondering if you looked at using the 15 pin accessory socket on the board (where the OPC-1939 cable plugs in to) to get the necessary connections you require instead of the front mic socket?

I've had success with soldering directly to the accessory socket pins on the IC400, rather than paying ~$70 for the Icom cable in order to use them as low power 70cm voice links.

Cheers,

Rob...

Hi Rob

I actually started looking at the Accessory socket on the main board when I learnt that the EPTT signal on that connector could be configured (with the normal consumer version of CS-410 #01) to get around the TOT (Time Out Timer).

As it turned out, I got a copy of the Dealer version of the programming software (#02) which can disable the TOT on the mic PTT, so I stopped looking at the Accessory connector.

I ended up plugging into the Ext Speaker jack on the rear panel, and with volume set at 10 o'clock, it feeds the intercom system quite nicely.

Yes, the Accessory breakout lead is a rip off!
