Fire Tone Out Search
I am resurrecting this thread because I have sold my GRE PSR-500 and Uniden Bearcat BCD996T and moved up to both a Uniden Bearcat BCD396XT and a Uniden Bearcat BCD996XT, They arrived Thursday, but I just opened the 996XT Friday evening and started playing with it under Butel ARC XT PRO software. Anyway, I have started collecting the two-tone sequential frequencies for several of the area fire departments and I want to configure this for unattended logging. The History Log function on the ARC XT PRO works great for regular scanning, but does not seem to log the Fire Tone Out A and B frequencies. In the meantime I have configured my set up as mentioned in a previous post here the delay set to Infinity. That will, of course, allow me to return and determine the first one (if any) found while I am away, but I would like to log all pairs. Does anybody happen to know if this is possible with this set up?
Also, when reviewing the found A & B Tones, are listeners here finding that the A & B Tones match precisely to those in the published tone charts, or are you finding that they may vary by 1 or possibly 2 hertz from the actually tone chart frequencies? For example, one of the tones I just decoded was 1512.8 hZ. The nearest standard tone is 1513.5 hZ (Reed Code 171). While they could be using non-standard tones, I suspect that the receiver is simply decoding and displaying the frequency without regard to the standard tones.
Any other tips on performing the Fire Tone Out Search would be appreciated. One thing I am considering is simply programming 10 different RF frequencies into Tone-Out Search and then scanning those same frequencies on a separate receiver. Then, when I hear the dispatcher announce, "Standby for Fire traffic..." I can tune the Tone-Out Search receiver to the correct RF frequency. The biggest problems I see with this are being able to select the correct frequency quick enough. Not all agencies announce that a call is pending and, even if they do, I am not sure if I will always be quick enough to tune to the proper channel.
