Thanks

Re: Reverse Burst Comments (Com Spec RB-1)
If you add a circuit like the Com Spec RB-1 board to the typical
repeater system using a ts-32/ts-54 board... the tx ctcss is not
disabled or removed before the RB-1 delayed ptt line drops.
So you have the phase inverted ctcss present for at most up
I haven't used one of those, but I'd ask, what is it doing differently?
If you invert the phase of the tone 180 degrees (or 120 for some older
motorolas), it should mute correctly. The only issues I've ever run into
is either the transmit delay is too short (ie, TK-x05D series), and the

Skipp,
I find your comments interesting in that the purpose that Motorola
had in using reverse burst of the PL tone was to quickly damp the
mechanical reed in the PL decoder to close the squelch and eliminate
the user from hearing the noise burst. But of course you knew that.
However, in

Anybody have other link to convert Low Band to 52Mhz.
Thanks and good week end.

My RB site pointed to an off-site
I played around with using the RB-1 board on my repeater transmitters using
motorola and several other receivers in tone squelch. Eventually I found it
was better to remove the capacitor which causes the RB-1 to send NO tone for
the last 100ms (or what ever the timing is).

In congested areas this is going to be a fact of life.
All your coordinator wants probably is a quick on air demo.

Coordinators are a savvy lot (well, some of them are), and they know
that sometimes a fellow will repeatedly claim that his gear is on the
air when in fact it is not. So, they want to be able to kerchunk the

Actually, the electronic CTCSS decoders react about the same as the old
reeds. The physics of the matter causes the filters that can discern

I believe the cap you speak of is to delay the transmitter

Steve,
I would recommend that you NOT use the Tantalum caps. They have a very nasty
habit of shorting when they overheat in the summer. When this happens
depending on where the cap is, you may cause a fire in the radio.
Not a pretty when this happens.
