Choppy Audio using hotspot

I have two OpenGD77 radios running the current firmware
I have been using them regularly on hotspots and sometimes direct to the repeater

Last week I noticed the received audio was choppy 100% of the time while on hotspots but fine going direct to the repeater.

I thought the issue might be my recent updated firmware so I reinstalled several older versions post april 1 - same results

one pi zero zumspot pi-star v4.1 (latest patched) GD77 on Brandmeister Colorado HD 31088

the other one a pi zero with a duplex N5BOC board on our local MMDVM System (pnwdigirtal.net)

If i use my Anyone 878 on the hotspots it receives fine, only the OpenGD77's have a problem

no known other changes since Pi-Star 4.1 final was released

Any Ideas?

Did you check calibration? Maybe you lost your hotspot RX and TX calibration when you moved to PiStar 4?

Good thought

But have not needed to make offset changes - all hotspots and radios under .5 ber

Thanks - Ron
