Batboard

Alrighty friends, I know I am going out on limb by askign this but does anyone have tips for scanning a talkaround and a talkgroup. When in talkgroup scan mode, there is long delay (sometimes up to 3 seconds), when someone keys up on the talkaround before the radio will catch it... For clarification I am only scanning 1 talkgroup and 1 talkground. I have the scan delay on the control channel set to 1 (the lowest it will go). Any other tips would be great. (The talkaround channel is a P25 ADP enabled frequency.)

thanks!
