On a PSR-500 in the Trunked System menu there is an option that says "Check All CC: No". What does this control? I can not find a reference to it in the maual.

This was added in a firmware update after the manual was written.
If you are in multi-site STAT mode, this option will control how the control channels are checked within the TSYS object.
If the option is on, every control channel in the TSYS will be checked on every pass through that TSYS.
If the option is off, only one control channel will be checked on each pass, but it will be a different one each time.

What would be the advantage of setting that option to off?
GTO_04
When it checks all control channels, especially if there are a lot of them, it can take quite some time to go through the TSYS when the option is turned on. With the option turned off, the radio only checks one control channel, so it spends less time in the tsys before scanning other objects.

Here's a question. Does it check all of the control channels that are active (in listening range) and skip over the ones that aren't active (i.e. too far away for the scanner to receive a signal)?
ROAM, which will Check CC's anyway.So I am in NJ (Listening to the NJSP), what would be the best setting for me since I am mobile all day?
Set Threshold lo to a higher value (85 or maybe even 90). However, you may miss traffic if driving route gets to far from any tower. 80-85 may be best.What I don't like is that when set to ROAM and more than just the one TSYS object is being scanned, when the scanner comes back to the TSYS object that is set to ROAM from another object, it seems to pick the first usable control channel that it comes to rather than assess all of them and use the best one.
Can someone here tell me what my seetings should be set to for the NJSP. I seem to have alot of trouble monitoring this system. I am using the pro-106. A little cheat sheet would be great thanks. I already changed the settings as listed above. I am just looking for some more settings.

This makes for some garbled digital voice when the voice channels from which ever site it picks are weak in signal strength. When only scanning the one TSYS object, it will only leave the best control channel when that control channel drops below the threshold, then it goes and looks for another one. I find that for the smoothest roaming between sites, scanning only one TSYS object set to ROAM is best.
I realize that it would take more time to assess all of the control channels in a TSYS object set to ROAM on each pass, but it would make for better signals if it would find the strongest site each time.
On the first pass, it finds what seems to be a satisfactory CC for your TSYS object. If the decoding percentage is at or above the level of your upper threshold, it will 'make itself happy' with that CC and return to it each time until it falls below your lower threshold. And yes, it doesn't matter if a better one comes along in the meantime. (I'm not sure that it actually even picks the best one, or if it just takes the first one that satisfies your threshold values) Maybe Mike or Don will chime in on that.
