NAC F7E bug in PSR-500??

[ech1253]

Hello

I duplicated objects with known NAC's and changed the NAC in the duplicate object to "F7E", but was unable to pick-up anything when I switched back and forth during a transmission...

Has anyone else tried to use the NAC "F7E" in a conventional P25 object and noticed that it does NOT unsquelch/decode every NAC transmission on that frequency?

Please advise.

What frequency are you doing this with? As I understand your post, you say you have duplicated the object with every combination of NAC and are switching between them manually?

The PSR-500 does not use F7E as a "wildcard". It uses a special, internal value that is set by pressing F3 ("Dflt") in the CONV menu, and displays "Search" when that value is set.

It is my understanding that the NAC "F7E" is intended on P25 transceivers to unsquelch/decode ANY incoming NAC's...

(see page 25 of this doc)

There has also been discussion of this on RR (search this forum for "NAC F7E")

The reason I want to use this NAC (as it was intended) is two-fold:

1) block out any analog transmissions
2) receive any other know NAC's that may be used on the frequency

Again, I am talking about a CONV P25 object...

If you want to block out any Analog transmissions, unmuting only on P25 digital transmissions, and displaying any NAC that might be in use, set the CONV object to:
Sq Mode: P25
P25 NAC: Search <-- via the F3 ("Dflt") key

Hi Don,

Thank you! Since I am hooked on your Win500 application, I noticed that in your program the "Squelch Mode" would be set to "NAC", but "Search" is not an option in the next "Squelch Code" field... Would "000" do the same thing??

Please advise.

Just type "Search" (or even just the letter "S") in the "Squelch Code" field.

Thanks... Yet another reason I will be registering my copy of Win500 today ;-)
