Radio Shack PRO-29 vs. PRO-90
 

Hello,

I've had a Radio Shack Pro-29 scanner for years, and it's worked great
for me. A friend just bought a Radio Shack Pro-90 which is also a
very nice unit.

However, the Pro-90 will not pick up any phone transmissions between
896.2000 Mhz and 940.0000 Mhz (the usual range I scan for portable
phones). I can not understand why it will not pick up anything. I
even found some active frequencies on my Pro-29 and set the Pro-90
directly to the same frequency...nothing. Turned the squelch all the
way down, just loud static.

Now I know the Pro-90 works, because it scans all other frequencies.
I can easily pickup police, fire, EMS, WX, etc. Just no phone calls
for some reason.

I can not for the life of me figure out why the newer, "better" model
can not pick up these frequencies...any ideas anyone?!? Perhaps it
needs to be set to 'trunking' to scan those bands? I don't know...

Any help would be greatly appreciated.

Thanks in advance!

Because the newer better radios filter out all the crap like cell
phones.

The phone traffic you are hearing on the 29 is images or harmonic ghostings
of the actual cell phone signals. The 90 is built to filter these images
out.

That's why these older scanners are still in such demand these days.
Unsavory, sticky-fingered jerks still clamor for such scanners cause they
can use this image problem to circumvent the cell-block. Oh well.
