ICOM m421/m411 replacement size?

Nos4r2 · 19 June 2021, 20:04

Looks like my M411 has just packed up,no TX when the button is pressed.

What's the current size equivalent? My sr 5.4 has a custom made grp box on the console that fits it perfectly, would be useful if I could replace it like for like.

Have seen similar reported in the yachty world... Fiat mic micro switch fault?

Would be worth checking the mic first especially with the custom console enclosure

Quite possibly, doesn't feel like the micro switch is working thinking about it.
It's old though and I should probably replace it, once these things become unreliable there's a chance it'll fail when really needed instead of during a radio check.

The templates are online for all the Icoms

You could just buy the same set and avoid the grief?

Thought of that one.
That's unfortunately got no 'buy it' button, guess it's out of stock. Can't find one anywhere.

Looks like it's the M423, though it's slightly larger. The 330 will fall through the hole.

If you end up going for something smaller, let me know and I can 3d print you a cover plate with your boat name/MMSI on it, so it looks like it's meant to be there rather than it actually being a cover plate.

Thanks

I've grabbed a new mic for now, just got to fit it-at under 30 quid its worth the gamble.
