*EDIT* - It appears my new home just has all kinds of wireless interference. Not only with the Edge remote, but all kinds of audio equipment on wireless transmitters won't work without intermittent dropouts. I'll chalk it up to either having a powerful 2.4ghz router, or the massive power transformer in the yard just outside my room.
I took my 1050 and Remote on a ride away from the house, instead of on the trainer, and I had no issues with it working. I was able to use the remote for the bell feature.
Please disregard this post.
