Pro-2006 Anti-Anti-scan mod for trunked radio

Pro-2006 Anti-Anti-scan mod for trunked radio

Post by Eric E. Snyd » Thu, 02 Dec 1993 01:23:12

I just saw an ad in Denver Post for a Pro-2006 modified to defeat
the anti scanning tones used on the Denver PD's trunked radio system.
I have tried listening to the Denver system and it really is almost
impossible to scan.  After each transmission, a noxious tone follows
for a couple of seconds.  What is the mod referred to in this ad?  
The asking price was $650 so I assume it is pretty sophisticated
(or perhaps the seller is looking for a sucker).

Actually the mod is not very complicated.  It was 'invented' by Bill Cheek
(author of a column in Monitoring Times as well as the Scanner Modification
Handbooks I & II).  He published the mod for the 2006 in a recent article,
sometime since about April.  What the mod does is to change the effect of
the "sound squelch" button so that when it is engaged, it will skip any
channel which has either a continuous tone or white noise.  I seem to recall
that it looks for a constant audio level and then resumes scanning if it
finds one.  If that is the only mod, then the guy is really high on the
price.  Bye...

This does not sound like a great deal to me.  The Bill Cheek board
costs about $30 as a kit (you install), and $50 installed by Bill.
-- someone correct me if I'm wrong --

The 2006 -new- is $350 mail order.  Used should be $300, or so.
I'll let you figure it out!

I have seen a mod-circuit to defeat the tone sent on the old
mobile telephone channels. All it did was listen for the tone;
when it heard it, the circuit punched the scan button. It also
delayed the squelch from opening up by about a half second so
you did not get the 'chirp' as it landed on 'tone' channel.
It wasn't that complicated, but it did require adding a circuit
board to the scanner.
