I'm having a problem with two APX8000 portables. The radios do not consistently receive traffic on encrypted talk groups. They transmit on the encrypted talk groups without a problem. We've verified all the keys are correct, they are selected appropriately in the personality, there are no switches or buttons that turn on or off encryption. I've tried everything I can think of including the affected personalities the the secure wide. Has anyone else ever run into something like this? Have any ideas on how to fix it? Thanks!

Andy,

Did you get your issue resolved?

I actually did finally figure it out. The digital modulation in the trunked system was set to C4FM and not CQPSK. Once I got that corrected it worked just like it was supposed to. I'm guessing we were missing a lot more, but we just happened to notice it on the encrypted talk groups because that's where our attention was focused.
