Hi Guys,

Here's my problem. I'd like to set up my radio (HT-1250) to alert me when my hometown fire dept is paged out. That works fine for medic calls which is a single tone (somewhere around 760HZ, forgot the exact freq.). However, when they page out for fire the tone is a very rapid warble. It is not preceded or followed by any type of single tone or two tone page, it's just the warble. What is this, and is there anyway to decode it. I know the FD uses VHF HT-1000s and Minitor pagers. Is it possible that this is just a alerting tone and isn't even used to activate pagers.

Any help is appreciated.

Thanks

Sean

Sorry Bro. That warble is strictly an attention getter. Now if they used a different set of tones than the medics, you could most likely do that. Generally... Big M radios will hold three tones on the same paging option screen. So as long as one of the three tones is the same, you can use just one channel. Otherwise, you will most likely have to use two channels.

From what I understand, the older plectron recivers did not do what the current minitors do now. Beep for the duration of the second tone, or for a long tone. They would quickly beep, and then open up. Because of this there was a "warble" sounding thing added to dispatch counsoles because it was an attention getter, and would add to the actual process of paging.

I'm not sure if this is completly true, I wasn't in EMS until late 1998.

I have noticed the warble used a bit on the PL version Minitor II as a extra wake up call

As far as the warble tone......

The post having to do with the plectron is correct..... It was called a "wake up" it was used no so much as a attention getter but was really ment for night time paging...... it was felt that when a person wakes up in the middle of the night for an alert they would miss the beginning of the message because you would not be fully awake right away...... When M came out with M1 even though you did not need it because of the built in alert most places were used to having it and kept it....

Even now we even program some place with different types of alerts so you can tell the type of call even before a word is spoken......

Other companies handled the alerts in different ways "Insteralert" made a home radio with a built in siren sound (even back then, way before the big M)......
