The 11 means the tones are both from Group 1, the tones are numbers 9 and 2, so therefore the tones are 539.0 and 368.5.NCSHP311 said:The only way I have to identify our Motorola tones is the four digit code of 1192, how would I know thw individual tones in hz from this four digit number? Thanks!
Thank you very much, that was a simple eas to understand explination. Now I know how to decode the tones....Thanks!N9JIG said:The 11 means the tones are both from Group 1, the tones are numbers 9 and 2, so therefore the tones are 539.0 and 368.5.
See the August issue of Monitoring Times, it tells you all about how to decode these codes to determine the actual tones, along with the charts needed to figure them out.
Using just my PC equipped with a fairly standard sound card I was able to use a couple software applications. The only other hardware was a patch cord from the speaker jack to the Record jack. I then used the computer speakers to listen to the scanner, and turned off the computer speakers when recording the scanner unattended.w4rez said:A similar question: Is there a reliable way to determine these tones from on the air monitoring or recording without purchasing hardware? I have tried several different pieces of AF spectrum analyzer software and found the results to be very dissatisfying.
