I've been looking for a inexpensive radar detector to use in Portugal, where the radars user are mostly Multanovas 6F ( Ka narrow low power, uncalibrated, from rear) and Traffipax Speedphot( K band I think ). There are some other systems which work on Ka narrow and K band also.
There are no Radar Detector Detector as they didn't published any notice of having them (which is demanded by law to publish every device used in traffic control).
My options now go for the Whistler XTR575 and the Quintezz Drive control, which I can get under 200€, but my doubt is if they are any usefull. It is not clear if the Whistler is able to pickup Narrow Ka band. About the Quintezz, I'm about to hear one review of a user that is not a reseller... :-)
Any advice appreciated!
