: Found some information here
leading me to a solution for the APRS issue. Below is a screenshot of my 878 APRS settings which have resolved the unintelligible transmission problem:
Take note of the time delay settings (with red dots) as well as the lack of a coma in "APRS signal path". These changes resulted in my APRS transmissions clearing up and finally showing up on aprs.fi
Update 2020: Updating the CPS and radio firmware to the latest (and matching) versions seems to have eliminated the above issues. Through the last year I have been using the 878 with to transmit my position in a number of challenging outdoor environments and it has performed and held up well. Looking forward to APRS messaging capability in the future.
