Ray70 Hailer

[Kevin]

I'm back on this issue after the boat returning for storage.

I've found that turning the Talking volume way down helped to cut down on the feedback. It wasn't noticeable at first that volume control was controlled on the base and handset separately, as the Ray70 was already turned down but not the handset.

I updated the bootloader and software for everything (v1.35 Application / v2.15 Bootloader / VH1.06 handset).

I do notice there is still a ring-like feedback from the flybridge mic. When I remove the mic and plug it directly into the back of the Ray70 it doesn't do it.

There is an extension cable being used that runs through the only chase to the flybridge... which also happens to have the 16/2AWG speaker cable going to the hailer.

With both the handset extension cable and speaker cable running next to each other would this contribute to the feedback? If so, what would help mitigate that? (twisted pair, shielded speaker cable perhaps?)

This is the only conduit and re-routing either cable would require quite a bit of work.
