Would you know where I could find a used one and also are base scanners stronger than hand helded scannersThe first trunk-tracker is the PRO-92, which can be programmed with software (WIN92). The thing about the RS brand is that they were made by GRE, Uniden and I believe others. You could look in the Wiki.
Yes... the base scanners are definitely stronger than the handheld ones, I would have no problem setting several books on top of most of the older base scanners, portables wouldn't take it as well.Would you know where I could find a used one and also are base scanners stronger than hand helded scanners
What is the oldest base scanner that has pl tones and programming softwareYes... the base scanners are definitely stronger than the handheld ones, I would have no problem setting several books on top of most of the older base scanners, portables wouldn't take it as well.
Ok... on the other hand a base has (had) more room for better filtering and spacing of components.
Thanks

What does that have do do with scanning? Your questions seem very vague. I think of it basically as a rheostat for voltage. Maybe it's just me.When did they stopped using the potentimeter

The Pro-197 was introduced in 2010. It was manufactured by GRE. It uses a potentiometer for volume/squelch. See service manual here:When did they stopped using the potentimeter
But it seems like that my Pro-2015 went further before the static than my Pro-197 does that make any senseThe Pro-197 was introduced in 2010. It was manufactured by GRE. It uses a potentiometer for volume/squelch. See service manual here:

The Pro-652 is essentially the same as the Pro-197. The Pro-652 was introduced in 2014 (manufactured by Whistler instead of GRE).

I'm not sure what you are really looking for.When did they stopped using the potentimeter
Now, we're rehashing the same thing in regards to Radio Shack scanners.What is oldest scanner that uses pots that has Pl tones or that can be setup by programming software
Why would this be important, or a concern? What is the advantage?What are the oldest RS scanners that can that uses a potentiometer
No they are not other than maybe he audio level, but not the performance or sensitivity.are base scanners stronger than hand helded scanners
You're trying to compare apples to oranges. What are you actually trying to accomplish or what problems are you having?But it seems like that my Pro-2015 went further before the static than my Pro-197 does that make any sense
That little difference with the squelch knocking out channelsYou're trying to compare apples to oranges. What are you actually trying to accomplish or what problems are you having?
Ok I understand and I agree. The squelch control on the PRO-197 almost acts like an audio taper potentiometer rather than a linear one. The PRO-197 being a digital scanner might have something to do with it's peculiar behavior but I don't think so. I actually thought at first it has a internal crack in the carbon ribbon track that was causing the abrupt jump but they're all like that. Maybe a design flaw but you'd think they would have corrected it over time, but no they didn't. Reminds me of Uniden and some of their blunders.That little difference with the squelch knocking out channels
Does that mean that the squelch on a digital is less than a analogOk I understand and I agree.

It's like a different animal, at least when you're monitoring a trunked digital system. You monitor the control channel but you never hear it even if the squelch is set to zero. Likewise if I set my SDS200 squelch all the way up to 19 everything works as it does at zero, no affect at all.Does that mean that the squelch on a digital is less than a analog

The control picks the active voice channel and lets you hear that.
