Re: Tk 3207
Set the "new" radios to "wide" on the receiver and see what happens.

Re: Tk 3207
Have you confirmed your company radios are running 2.5 khz deviation narrowband and that the "cheap" radios are properly programmed on frequency?

Re: Tk 3207
Have you compared the audio on those radios to another radio you know works fine? Is it possible the transmitted audio just sounds bad? What frequency are you listening to?

Re: Tk 3207
The wide / narrowband issue depends on what you are listening to. If you listen to a signal that has deviation at 4-5 khz on a radio set to "narrow" it is going to sound horrible, but you can listen to a NARROW (2.5 khz deviated) signal on a radio set to WIDE and won't notice much differen...

Ya, I doubt that was done to give people the opportunity to tune out
The radio traffic interception rules are probably irrelevant to you if you're doing crime in the first place.

Re: 417.8 Repeating or Simulcasting RFD CMD 1
Not knowing whether he has a single or dual stage mixer, it's hard to tell. I don't think his receiver is dividing down to land at 417.800 by design, but it's a harmonic image. One thing I know for sure is that RFD is not transmitting on 417.800 Mhz, so if he's hearing it, it's got to be a harmonic ...

Re: 417.8 Repeating or Simulcasting RFD CMD 1
460.575 - 417.800 = 42.775. 42.775 / 4 = 10.69375 or 10.7, so your scanner is running an intermediate frequency amplifier of 10.7 Mhz (typical in most scanners) which means you're hearing a 4th order image. I bet if you cracked open the case of your scanner and looked at your circuit board you'd fin...

Re: 417.8 Repeating or Simulcasting RFD CMD 1
It seems unlikely RFD would be there since that is in the Federal band. Sounds like your scanner is picking up an image frequency. Here is some pretty good reference material on the issue.

Re: Peeling the lid off the can of worms…again.
Interesting report…especially at 3:00 min into it.

Sort of removes the logic from the popular "only encrypt the tactical channels" argument.
