Mike, thanks for posting this. You have just solved one of my greatest mysteries of the MARCS System. I could never understand how I was getting 50-60 hits a month on a particular Wildcard TG on MARCS yet it never ended up in RR. Now I know - Status Bits. Great information.
There isn't an easy way to do that on a PSR-500 that I know of. I think you're choices would be to (a) use group wildcards and live with the transmissions that have a status bit set, (b) turn off the group wildcard, or posssibly (c) create those specific talkgroups that you want to ignore, in the scanner, and then lock them out.And how do you do that on a PSR500?
