I programmed my V1 in more responsive Ka mode the other day and all I've noticed is occasional Ka junk, which never happened before I made the change. I wonder if this setting helps you when it really counts, or if it just keeps an already detected bogey in range longer. Has anyone here noticed any real benefits as a result of this setting change? Ka band detection is all important in CA since that's what is used here more than anything else. X band is not used at all in CA, so I turned that setting off. In fact, don't even see K band being used at all around here except for automatic door openers. Does anyone else here who lives in CA see K-band coming from patrol cars much these days? CHP exclusively use Ka and the local Sheriffs in my neck of the woods emit nothing but Ka as well.
