ICOM M401Euro question

[martx007]

Hiya,
Could anyone judge if my Icom is faulty?
I cannot get it to communicate with my Raymarine 101E handheld i just bought.
I have not tested the icom since i purchased the rib at the end of last season. If I leave the icom in scan mode and transmit on a channel with the handheld it just makes some white noise but no voice. And visa versa.
Have tried on various channles.
However whilst working on the rib sometimes i have heard liverpool coastguard on Ch16 so know that it will receive.
I have tested the raymarine with someone else's handheld and communication is fine.
Both are set to International channels.

Any ideas gratefully received.
Martin

Have you checked the aerial cable? Try taking it apart, (assume you've got a PL259 type), rethread after cutting back a few inches of the cable in case you've had water ingress problems.

As VHF relies on co-ax, you can often get a cable issue with one side of the tx / rx process but not the other.

Failing that, connect an SWR meter in line and this will help you do some basic checks.
