HI Bill, Ken
My QLG1 GPS doesn't interfere with my QCC operation either.
But RF is black magic. There are a lot of factors. Grounding, SWR, coax common mode currents. Everyone's shack is different and has different problems (to make things interesting).
My suggestion is try disconnecting the LEDs. Particularly the yellow one. It may make all the difference!
Another idea... put a little capacitor in parallel with each LED. That can slow down the sharp edges of the serial data inflicting power line noise due to the switching of the LEDs, and let you keep the LEDs but suppress a bit of noise.
Other than that... lots of capacitors across supply lines. Ferrite is your friend. (At least, whoever you buy ferrite from will be your friend, soon enough).
