icom m411 problem

dougcrock · 15 July 2011, 08:33

Icom m411 3yrs old seems to tx but will only rx when squelch is past threshold ie hissing all the time
tried 2 aerials same prob as Erin maybe
any advice appreciated
before i try bouyancy test

on it

Erin · 15 July 2011, 09:22

Yes, does sound very similar. Although mine won't tx properly either. Is yours intermittent too. I'll be trying a new aerial soon to see if that cures it.

doesnt seem intermittant but seldom use or check vhf
phones work better with all our hills and lochs

Maybe they meant "iffy" filters - that's why it wasn't working!

My guess is a glorious typo and they meant RF. But with service like that, does it really matter?

IF Filter = Intermidiate Frequency Filter(s).

you learn something every day
as an aside the vhf is dash mounted but the case design has convex curves on the sides

therefore it cannot be easily sealed to prevent water going past and into the console without silicone and mess but its working

Courageous · 29 July 2011, 09:42

Agreed Doug - I fitted one on mine and was bemused by that profile! The clamping arrangement doesn't lend itself to compressing the rubber seal either does it? They've let themselves down a little there methinx.........

dougcrock · 29 July 2011, 09:53

mine does not have any seal supplied to go between radio casing and console i made one but as you said profile dosent help

Courageous · 29 July 2011, 10:13

Eek! No seal at all? Mine has a rubber square profile under the facing flange. I wonder what happened to yours Doug?

dougcrock · 29 July 2011, 11:19

I dont believe that seal is for the console / radio casing seal but instead seals the radio which is waterproof no probs there but water can go into back of console where all the wiring etc is

Courageous · 30 July 2011, 08:41

Hmm..... I wonder if yours is slightly different then? Mine can't be for anything else, unit flange mounts against the console and in between is a square section rubber seal. What else would it be for? For me it's just the clamping arrangement that's the weak point.

dougcrock · 01 August 2011, 08:56

the rubber flange on mine doesnt touch the console and had a look at treemendos's one and his is same
Your right about clamps espesially in confined area
