Batboard

problem solved

Jon,

We did simular mods to remove reverse burst and dropout delay.
I have my notes at the other location, will get them tonight for you.

So your the only one that sounds good on the repeater!!

What's the big deal with having the reverse burst? Most
other users on a repeater will make a comment that your
signal sounds good. What is different in your radio
that the rest of us don't have is the normal question.

So your transmitter stays keyed for an additional 150
Miliseconds. Does that make your transmitter worse
than any other? Most people would rather hear
a transmitter with reverse burst used on a toned
input repeater. You don't end up with the noise
burst at the end of your transmission. It sounds
clean.

Sounds like you want to go to a bunch of work
to modify a radio that is working just fine.

Jon,

Check your PM's

It sounds like you are talking about two different things.

Do you mean you want to eliminate the reverse burst on the repeater transmitter? If so, there is a transistor in there somewhere that can be shorted to eliminate the phase shift. Either that, or bypass the delayed PTT that is on the encode/decode board. Essentually you are making this a carrier squelch repeater that just happens to have a PL encoder on it. Bypassing the delay will accomplish it because the transmitter will drop immediately.

If you are talking about reverse burst on the repeater receive side, the only way to get rid of the interaction is to replace the reed decoder with a solid state decoder that doesn't understand phase shifting. An OLD Comspec will do that job. That will give you a nice loud burst of noise when unkeying.
