I found a Old round back 2001 the last time I was in Union Grove not far from downtown I saw the 2001 while I was there: http://mass73.elementfx.com/sirens/racine_county_wi/village_of_union_grove/school_yard_park/100_0969.JPG http://mass73.elementfx.com/sirens/racine_county_wi/village_of_union_grov...

I was thinking that it was but I wasn't really sure.

I think the second one would be previous speakers for Tsunami sirens in Christchurch, NZ before they got Meerkat sirens. Not really sure though.

Ok. I will try that tomorrow and tell you what happens.

Are you using the common tone as your first (A) tone or your second (B) tone? Also, what are your tone durations and gap (if any)? I am using the A tone for the common tone and the B tone for the function. The A tone is 3 seconds and the B tone is 2 seconds, is that right or should I use the Motoro...

If you can hear the tones you are sending through the speaker then the receiver, CTCSS circuit, and antenna are all OK. This test doesn't verify the receiver sensitivity, but it should close relays if the decoder matches your generated tones. The two tone decoder pictured uses L-C filters which mig...

Wow. That looks kinda rough. Your best bet is to bring it to a radio shop to have them look it over. Is that the one that was on eBay a while ago? Are there any radio shops that you recommend? And yes, this was on eBay a while ago. What kind of antenna is on it? If it isn't in the Frequency range o...

I recently purchased a Federal Signal Siratrol radio (Two-tone) a few months ago and I have a radio set on the frequency and CTCSS/PL tone. When I transmit the tones on the front tag of the radio, it doesn't respond and I don't hear any relays click but the radio is picking up the tones through the ...
