figured it out
You need to turn hotkeys on for this to work
OPEN SAY CONVENTIONAL FREUENCIES AREA IN GRE PROGRAM.
LEFT CLICK WITH THE MOUSE ON THE SQUELCH AREA IN GRE PROGRAM.(do this like you would try and change the nac code)
THEN HIT CONTROL AND A.
THIS TURNS ON ALL,the sceen turns blue or highlighted.
THEN YOU CAN TURN ON AND OFF THINGS FOR ALL FREQUENCIES
LIKE AUDIO BOOST,OR THE TONE SEARCH ,SHUT OFF AGC FOR ALL,ETC...I MADE ALL MINE CODE SEARCH AND IT WORKS GREAT!
SOME DEPT USE MULTIPLE NACS OR PL tones.
The best part is this is the only scanner I know that does this!
Prolly works with other programs too .
If you set SQUELCH to SEARCH it will find pl or nac codes on that freq,why you wanna do this?Dept using multiple nacs,pls,you trael to other areas.If theres no pl,it doesnt matter,it works anyway.Like for aircraft,etc.
