Fixing Icom 400 pro mute / selcal problem

[mjr350]

Hi Guys

I have a Icom 400 pro set up as a 40ch UHF CB in the 4x4 and its worked flawlessly for 3 years but has recently stopped transmitting on most channels unless I hold down the MON key for a few seconds. It makes a funny digital noise and then is able to transmit on all channels.

I have worked out through 3 months of searching that it has something to do with the selcal tone mute setting (or something like that) but no one on the countess forums has actually given instructions on how to reverse the settings to let the radio transmit again. I'd say I've hit the wrong combination of buttons in the settings mode and turned something on or off while playing around.

I have a clone cable but have changed to a new computer and lost the software in the process and it seems that Icom have asked everyone to remove download links so that's a no go.

Is there someone that can either translate the technical user manual or share a step by step process to bring it all back into order.

Cheers
Mitch

What country are you in? In U.S. a small portion of 462 and 467 mHz is used for GMRS and FRS but we don't have a CB band in the UHF range. I had to Google Icom 400 pro to find out what kind of radio it was. I never saw a service manual listed, but I did not look very hard. Have you tried a local radio shop that sales the radio for help?

I'm in Australia.

I managed to finally fix it.

I looked at the settings of a channel that worked and found that one of the settings was switched on instead of off. I'd say something to do with the CTCSS

Its only taken 3 months but she works now.
