I got a Couple of Questions
one When I Monitored Walmart with my Pro97 FRS freq 467.5875 I Noticed The Ctcss Code Search was Jumping all Over The Place 100.0 to 217.8 What Gives Here ??

also my Pro 97 Manual says I can Monitor LTR Trunked Systems dose This Mean I can Monitor Wa DOT ?? also Why arn't DOT freq.'s Listed on Intercept ?

on 01/12/06 I saw an San Juan County Sheriff's Patrol Car at Home Depot Here in Moses Lake Wash,

I'm not sure what you mean by jumping--was it scanning thru and not stopping or hitting several along the way. I have seen, very breifly on some radios with ctcss decoders that will stop based on a subaudible tone a human voice can inflect, but usually it will not be the correct tone being encoded. Usually FRS users dont know how or care to enter one of those insipid 'privacy' codes.

Don't know about pro-97 and EF Johnson system monitoring, I usually listen to the status channel on a regular radio if I'm interested.

Maybe the San Juan Sheriff wanted drier lumber.

8) Thanks for The info (it Scans Through The CTCSS Tones)


BTW
What Freq is The Status Channel

The WADOT Radio System is an E.F. Johnson Multi-Net II System. As I understand it, there is no current scanning radio that will track this type of trunking system. Correct me if I'm wrong here folks.

I have had some luck in monitoring (tracking converstations) on that system, in the conventional mode, by also entering and monitoring the channel frequencies exactly 1 mhz directly above and directly below the specific active channel. Try it sometime when you're really bored. It does seem to work.

I don't have a PRO-97 -- but I have been told that it does indeed do LTR. As for the possible tone problem -- there are TWO things to keep in mind. FRS does NOT use standard FM. This is to protect the GMRS users. It's like listening to AM on a FM radio. --- You can hear it -- but it's not clear. And second -- All DPL codes also transmit a 134 hz tone burst. It is very common to receive a FALSE tone of 131.8 or 136.5 -- when it is a DPL tone. The real DPL tone doesn't read out -- just the on - off tone burst.

:) Thanks for all The info guy's Now all I Have to do is Figure out Wa DOT Trunking setup and get it going 8)
