    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.

    BC355N vs BC355C frequency question

    I have a frequency of 152.850 however my BC355N only programs to 152.855. My BC355C on the other hand will program to 152.850. Will this make a difference on the BC355N if it is on 152.855 vs 152.850? Will there be clarity difference? Isn't 152.850 a valid narrowband frequency? So why won't...

    Wide or Narrow band (eternal question)

    Hi! I've read a lot about Wide vs Narrow band. But I didn't really understood what is it... I put my handheld to 162.55 (NOAA 7) and I get a louder sound on Narrow. On Wide it's quieter. My understanding of it is that a frequency on 162.55 MHz on narrow band is +/-2.5 KHz (162.5525 MHz) and...

    Narrowband Issue with VX 824

    So I have a few (3) VX 824-G7-5 that are doing some odd things when I program them into narrowband. The radios worked fine in wideband and are part of a larger grouping of radios 45+ all same model. When I program the radios into narrow they tx fine but they do not rx at all, they rx nothing...

    Do any yaesu HT do a 6.25 step narrowband

    Does anyone know if there is or "in the works" yaesu ht that does 6.25 step for the mandatory narrowband change of 2013. It's hard to believe that cheap Chinese market radios do this step but others don't, whats the deal?

    PSR-800 and Narrowbanding

    Is there anything I can do to improve the audio of a narrowband signal. Our Sheriff's Department went to narrowband. The signal is good but it sounds all digitized and is often difficult to understand. Thank you.

    Whelen Storm Sirens

    Our community purchased and installed (8) Whelen storm sirens around 2003-2004. These sirens have a VHF transmitter/receiver that decode the DTMF activation tones and other commands and then can "talk back" to the system reporting the "status" of each individual siren.

    PSP VHF and narrowbanding

    We all know the PSP has by and large migrated to the OpenSky system, with occasional fallback usage on the VHF system. That's no longer in question. However what I find interesting is that the state has very recently modified 75 of the PSP VHF licenses to add 11K0F3E (narrowband) emission...
