I do this with a rat shack wx radio and it works flawlessly.. I use an aux input on my 210 for audio straight from the volume pot and find the mute line in the radio to run the alarm port. The advantage with this setup and specifically the radio shack model radio is that it takes care of the mute for me, allows me to use the weather button for testing and most importantly it mutes with the end of message signal instead of a timer like the midlands. I am slowly working out a way for the 3 lights using alarm inputs to change the tail message based on advisory, watch, or warning. The next project is to get a simple voice recorder chip to record the warnings for playback later if you missed it.
Do your self a favor and get a radio that responds to the End of message signal and you'll save your self a bunch of headach. i have an older rs model on the repeater but their current one for around $70 that I use in the rv mutes also on the end of message signal Rob.

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: >More than 3 ports?
