Just my 10 cents worth, the VIGILANT MICON SR532 has a  rather elegant  
motor driven preselector as per Eddy1650  Racal 1772( Same   board used I 
believe 
on the optional preselector unit for the 1792) etc,  and my  observations of 
the Vigilant one is that its really good, my  last QTH was  literally yards 
from 
a pager TX, which should have been  dealt with by the high  pass filter in 
the 
receiver, but was not, and  the Vigilant preselector did the  job of 
rejecting 
it, in fact, the  only PREMIUM-RXs here that were FULLY  able to deal with 
the 
pager  were the SIEMENS CHR531, now sold, the SR532,  and the RF-590A, both  
now up for sale, as I am no longer at that location, Dave   MW1DUJ.

Hi Dave
 
I didn't realise the Vigilant had a motorised preselector, but that's  
probably because my efforts to snare one via the usual hunting ground has so far  
proved unsuccessful:-)
There is quite a nice looking 590A on offer right now, but that's also much  
too expensive for me:-)
 
Seriously though, that does give me another reason to keep looking out for  
the Vigilant.
What Michael didn't mention was that there are still quite a few  sets 
available, usually marine kit, with very nice manually tuned  preselectors.
Sailor and ITT Mackay are just two commercial receiver manufacturers  that 
come to mind, and even Kenwood did a pretty god job with the  R820.
 
Collins also did a nice job with the HF8060 but that does need some  
interfacing if not used with the appropriate Collins kit as it's bus controlled  only.
Unfortunately though, as Gary pointed out earlier for the Harris  kit, this 
is another one intended for HF use only.
