RF Interference

I thought I would mention this in case it is useful to someone else.

When I first got my OS2 I had some difficulty in programming the radio to control the openspot. Thanks to help given on this board I resolve all but one issue. I could not get the radio to change reflectors/repeaters by keying the transmit. I thought I must still have an error in the settings on my radio, but before I could look further into this I started getting issues with my Jeep. The keyless entry system and the push to start all stopped working, so I left the radio problems to fix that.

Keeping a long story short I discovered the keyless entry/push to start was set on a frequency of 434MHz quite common for such systems, and the OS2 as delivered on 433.9MHz. Changing the OS2 to 432.9MHz resolved all the issues with my Jeep and also now the OS2 changes reflectors/repeaters as it should.
