I had a Garmin 95 XL that lost signal every time the VOR was tuned to
108.8. Finally figured out that it was the associated DME channel. ie,
when my DME transmitted, a harmonic wiped out GPS reception.

108.8 is/was also one of the freqs that would cause my old Garmin 90 and current
Garmin 196 to lose reception. DGB
