Hi Gang,
I monitor the San Diego RCS North Zone exclusively. The vast majority of the digital transmissions are crystal clear, however some digital transmissions are garbled, choppy, sound like someone talking into a barrel, have electronic background noise, or have other quality issues.
So now a few questions:
Has anyone found the optimal audio quality settings for the 296d on the San Diego RCS and if so could you share them? I've tried several settings but can't get rid of the problem. The manual says that the lower the quality setting the better the sound quality so I'm now at 333. It seems like the longer the transmission, the greater the chance that the sound quality will deteriorate.
Are there any other settings I should be looking at? I once had a squelch setting issue but that has been resolved. I recently upgraded my firmware to the latest with the rebanding capability and sound quality has improved but it has not totally eliminated the problem.
Or, are these occasional audio quality issues just inherent in P25 transmissions and I just have to learn to live with them?
Thanks in advance for any wisdom you can share.

EDIT: So I was just reading about simulcast systems in the wiki and maybe that is the root of the problem. I'm about 4 miles from one tower with direct line of sight and about 2 miles from another tower with no line of sight. Maybe one tower site occasionally interferes with the other?
