If the hailer is installed on the arch there is just too much feedback from it to be useful as it seems it is to close. Is there any secret recipe to eliminate feedback when the hailer is installed not far enough from the mic?
An older radio won't have a feedback eliminator, but newer ones should. They might not, but they should. A fairly inexpensive Behringer graphic equalizer for an audio system has a feedback eliminator and these are far more expensive- I see no reason for them to avoid using one.
To avoid feedback, stay behind the mouth of the horn. The horn isn't supposed to cover anything behind it, but any hard object ahead of it can reflect the sound back to the mic. You can also test the mic, to see how much sound it picks up from the side or behind- ideally, it won't pick up anything from behind and sounds from the sides should be significantly quieter than what enters directly toward the mic.
The Carver that has the hailer I asked about has canvas ahead and behind the forward-swept arch, so it should prevent feedback if the hailer was loud. OTOH, I was under the canvas, so I didn't really get the full effect.
