Normally on my commute to work I don't pass any locations that generate false reports. But in the last week a particular town has been moving a "Your Speed is Trailer" around that runs K-Band. The V1 has been picking it up just fine with the usual performance.
This AM turned the V1 on and it went through the test procedure just fine. Showed All Target mode like usual. And away we go......that is until I came across the Speed Trailer which was clocking my speed, but not a peep from the V1. Ruuut Rooo! I then made a detour to a store complex that has both X & K motion sensors, complete silence from the V1. So I traveled a couple more miles to do an errand and turned the V1 off while out of the vehicle for about 5 minutes. On re-tracing my route the V1 sounded off fine on passing the store complex on both X & K band.
The pizzer here is that normally the only radar sources I run across have a badge behind them. And in this case I had no idea the V1 wasn't listening. And then after cycling the power it was listening, and next time............?????
Apparently the self test startup procedure is rather limited in it's diagnostic capability, and doesn't prevent you from driving around with a totally deaf V1.
Oh well, time to dig out the trusty RX65.
