Would someone please explain in detail what the ZM Threshold, ZM Slope, and ZM delay are on the Whistler TRX2?
thanks

Well, they all have to do with the ZM. The first is the Threshold, the second is the Slope, and the last is the Delay! I know this because I translate furniture assembly instructions for a Chinese company!!
Sorry, couldn't resist! I too would love a good explanation of these....
I guess they control how the scanner homes in on the correct frequency.
It's not an AFC, it's the opposite. It the received frequency are not spot on it will ignore it.

After unchecking the Zeromatic check box in the menu (default = ON) the TRX-1 is working fine again in search and tune mode.

Did you mean Flex Step as I don't see a Zeromatic on/off option? It could be right in front of me too, just say'n lol

Yes, that is totally wrong. It is explained in older GRE scanners manuals. Older scanners used to have a selection of 5KHz turbo step in search and it would stop on frequencies that where 5KHz off, or more, and by using ZeroMatic it only stopped on the correct frequency. The scanners tuning need to be correct and if using ZM makes it skip channels that are supposed to match then something is wrong.
edit: I did a search with ZM off and it stops 6,25KHz both before and after the correct frequency with any strong DMR site. So it works as it should in my TRX-2. Values are Delay=50 Threshold=1180 Slope=520

They why are there THREE parameters Threshold, Slope and Delay?
How could you possibly need three if it's just a simple variable size window the signal has to be within?
