Sirius radio causing V1 to go crazy

[Tucker2930]

I mounted my Sirius radio on my R1200Rt today and anytime the radio is on my V1 is showing one radar behind me. Turn off the radio all is good. Anyone had this problem?

Yes I did, it was my antenna, the antenna that came with the unit worked fine but I didn't want 20' of wire so I ordered another with 4' of wire, whenever I turned on the xm my Valentine would show ka to the rear.
I even tried it in my truck, same results.
Put the original antenna back on and haven't had a problem since (6 months or more)
forgot about it and when I put the Valentine in my truck where the short wired antenna now lives and had the same annoying problem again.

Another V1 / Sirius interaction I discovered this week in my car is with the remote control for the Sirius Sportster. When you push the #1 key (or is it #3?), the V1 thinks it's being lit up with a laser and alarms at max. I slowed down 2 or 3 times before I figured out it was my own doing.
