VHF Hailer & Listen Back

[SteveHall]

Has anyone got a hailer linked to their VHF for use as PA and horn?

I've got myself a hailer and want to put it on the A frame facing forwards for use when training / safety boat or as a starters horn (if it works well enough)

it says in the manual for my VHF that the hailer will also listen, so I guess I talk through the mic and this comes out the hailer and then the hailer listens and plays the sound though the VHF - so gives me better chance of hearing replies but my question is.... Won't I end up getting loads of feedback as the hailer will be behind the VHF? I know I won't know for real until I try it but thought I'd ask.

On the icom you can adjust listen and pa volumes independently - thus avoiding exactly what you describe !

Thanks - Will have to see if my Lowrance unit has the same facility....

But have you got your hailer on your A frame?

That was what I found (SH PS-2000 and the Command 310 Mic, going through a small horn speaker on the A-frame or anyplace else I could locate it.) It is currently disconnected. I have toyed with trying again with the horn facing astern atop the arch, but haven't got there yet.

Do you have any photos of the installed hailer?

Steve,

I have one fitted to my boat. It is facing forward and works fine as a loudhailer. I didn't know, and therefore haven't tried, to "listen" with it.
I have an ICOM M603 with a command mike, if that helps.

if you watch deadliest catch you will see that the crews on deck talk to the wheelhouse using the talkback. as far as i know they dont need to press an buttons etc for it to work, so a problem i can see if mounting facing forward on the frame is that it will 'hear' loads of wind noise as you are moving and your radio will sound like its suffering from interference.

I'd assume that the talkback only works when the radio is in "hailer" mode & not when listening on VHF.

yeah id be inclined to agree with that, but if using for training say dinghy sailing then it will most likey be in that mode most of the time

you might be able to toggle the talkback feature on/off. I'll have a look & see if the user manual is available on Icom's website. I've been in situations when a hailer would be handy & it's something I've considered. The GRR springs to mind

I heard you shout at that little kid playing on the climbing frame while we were camping at the GRR ... You don't need any loud hailer believe me .. !!

That weren't no little kid, that was a budding serial killer that needed bringing down a peg or two. Lacking some male influence on the home front if you ask me😡

That's how I want to fit mine ( a frame forward facing) I will be doing mine soon so will let you know how it goes.

[SPR]

if it helps - I use 323 training radios and only time I experience feed back is if the two units see high volumed and sitting 1 foot apart and it's the second radio that causes it

Well dummy mounted this today on my a frame, and I get nothing but feedback - gee my ears have only just stopped bleeding.

I attempted to out it in the console and again nothing but feedback, so looks like it's going back in the box
