HP-1 P25 Transmissions sometimes garbled

I figured I would post this in here because I don't believe it to be specific to the HP-1 and probably a setting that needs tweaked. I have 1 P25 system programmed (all sites with selected talk groups). Occasionally, in the middle of a transmission, one side will become garbled (literally mid-sentence) for a very short time. I know it's not encryption. Is this something that is inherent in digital systems that I should just get used to or is there a setting on either the system or talk group that I can try changing. This is my first digital scanner, so I am not well versed in all of the various troubleshooting techniques for monitoring digital systems.
