• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    Help for the signal identification and any info for modulation

    Hi to all, I am open :) to all kind of info related to two printscreens. Modulation, working type and any small info will be appreciated First picture can be M FSK but M ? any info about modulation... Second picture is a different signal, maybe phase modulated ? why so wide ? Thanks, WR

    P1 vs P2 Indication?

    Is there any way to tell whether a received signal on the G5 is using P1 or P2 modulation? According to RadioReference, some of the talkgroups on DaneCom (Dane Co, WI) are using Phase II modulation, however, none of the talkgroups in the database are listed with a Mode "T" (TDMA) designation...

    Galaxy DX 959 no modulation

    I have a DX 959, and to get more output, I adjusted the SSB power variable resistor (VR 17) all the way to the right. I was getting great output and I could make the mod meter swing all the way to 100%. Now, I can't get the meter to move off of the pin. Everything else seems to be working...

    scanners with multiple modulation types?

    I was looking up some Uniden scanners and I noticed that for any given frequency range they only use one Modulation type. Anyone happen to know why? Or what scanners can switch Modulation types? Is this usually a problem with UHF/VHF? Thanks

    MOD Factor of D-VOR

    I have DSB D-VOR. Anyone know the meaning of the formula of "AM Modulation factor" of D-VOR's "9960FM". When i know RF Power of Carrier[Pc] and each Subcarrier(Upper Sin[Pus], Upper Cos[Puc], Lower Sin[Pls], Lower Cos[Plc]). and each value is as follows... Pc=200 [W rms] Pus=5 [W rms] Puc=5...
