i am trying to use a weather receiver on aux 1 input when i turn on aux 1 it
transmits as it should but when i turn it off it stops transmitting but then
when the repeater is keyed i can still hear the weather radio on the tail am i
doing something wrong or does the aux audio inputs not actually get shut off?
The writeup from Ken specifically says that the aux audio ports are dependent
on the audio source having it's own muting. That's another way of saying that
they have no switching.
the weather radio is a WR100 Midland and i plan on just leaving the
audio on if i can get the aux port to actually shut off and if that
works use an alert port to call a macro to turn aux 1 on until it times out
I posted this on the rc210 forum and no responses from anyone so
figured i would try here
thank you
The weather receiver is going to unmute when the SAME code you
programmed comes in, and reset itself on the timer built into the
receiver. You are feeding audio top the aux port, and it is mixing
to the transmitter. The 210 is working just like it should. The aux
ports are NOT muted.
The cure is simple, and cam be implemented two different ways:
1) Add a 5vDC reed relay to your system (maybe mount it inside the
Midland). Wire the contacts across the Midland receiver reset button,
and the coil from +5v to a digital output. Then modify your "shut up the
weather receiver" macro to pulse the digital output. That resets the
Midland, and it mutes.
2) Wire the relay in series with the audio from the Midland to the aux port.
Program the 210 to switch the relay on when you want to hear it,
and off when you don't. This method uses the relay as an audio mute.
I suggest you go to www.repeater-builder.com and click on Arcom,
then on "More than 3 ports?"
That's Ken's writeup on how to implement the IRLP hookup to an aux
port. The weather receiver is similar.
The text from the repeater-builder page specifically says:
