Copied from an auction on a NZ site...The seller is keen to ensure people understand the inherent dangers of buying a 2nd hand model........ :wink:
Is he at all accurate in his 'theory'?
In his sales blurb: -
NOTE: Any (Superheterodyne) Valentine 1 over 3 years old will be out of calibration, and may not detect all NZ radars.
In answers to questions :-
radar detectors are active superheterodynes operating 16.000Ghz Valentine 1 is, as these r active oscillators they drift with age, temp, bumps, No problem really, for the 1st 1-2 yrs, cause the Valentine covers wide range of freq. As the unit ages, gets abused (electrically also) will get further out of tune, usually moves 2 lower radar band. To the point where it will start to not detect radars that run at the higher part of the radar window, Is why so many BEL STI fail after 12-18 months
Then someone challenged and he came back with this!!
Theory, its fact. Forums? that's high tech. You have 20 more years to catch up. V do not acknowledge that they have new software each 3 months or so, either? And I am sure any manufacturer will happily tell you all about design issues? If you own and use any "high end" superhet ( V1 & STI) every day for more that 3 years, you may not have, judging from your stated BEL and Valentine experiences for 10 years, you will notice changes in false alarms and performance caused by calibration issues. END
So...Fact, Theory or sales crap.....??
