When I was playing with SAME weather radios a couple of years back, I
called the local NWS weather office and found out what time they were
going to conduct their test. I then set up a timer on a cassette recorder to
record the broadcast.
I guess you could use this as the audio source for a service monitor, but
what I did was just inject the audio into the weather radio at the volume
control. In my case I wasn't going to use the RF section of the weather
radio as it got clobbered by all the RF on the hill I was on. I think I used
a GE Phoenix as the receiver, and then coupled the audio to the weather
radio so I could use it's SAME detector. I just injected the audio where
I was going to inject the receive audio. It worked just fine.
