Upgrading my VHF from a failed ICOM 323 and after a new unit. So after some suggestions.
I hate the way that VHF microphones tend to be hardwired to the head units. The mic on my 323 has failed and requires removal of the entire unit for warranty repair. The only manufacturer I have found that has removable microphones for conventional fixed radios is Garmin, and they are bloody expensive!
The ICOM423 is very reasonably priced, same form factor (so no dash butchery or holes to fill), and supports auxiliary removable microphone. I also like the fact that you can connect a speaker for PA / Horn purposes.

Also tempted by the ICOM IC-M400BB which is a black box receiver, and only supports removeable microphone (plus horn/PA etc). This would allow me to repurpose the existing hole for the 323 in the dashboard for a glove box or a Fusion Stereo which would be nice.

Both of the above have active noise cancelling technology, which is lacking on the 323. Very useful on a RIB.

Interested in other folks views.
