Each time the DME was tuned back to 109.5 the GPS
lost its satellites.
Just thought I'd share that in case anyone has a GPS loss of reception
in flight. It could just be something as crazy as this.

Sounds like a harmonic of the DME receiver's local oscillator just happens
to be at the GPS frequency. GPS runs on very low signal-to-noise ratios, so
even a low-power source can swamp the GPS receiver. Thanks for the
heads-up. Hope I can remember it if the GPS seems to quit.
