Hi SnelleJef,
Thank you for your trust,but I confess that I'm put in a messed-up situation,to recommend a product on other people's money.And I don't want to make a mistake at other people's expense,in this case,yours.
I also have to add that I do not know the sensitivity of the two receivers mentioned by you(Vu+ & Octagon),because I have never tried them.The only thing I can say with certainty without mistake that the tuner of 5927 is the most sensitive to weak signal as that of the 6983 or 6903.It's actually in the same performance class as the last two,and besides,has full crazyscan support.
From this point of view and with dvb applications 5927 can be used for many things,i.e.signal checking and monitoring, MIS reception, antenna installation,reception of special parameters, etc.But you should know that it does not read and lock the transponders with the S2x extension!You must take this into account if you want to compare it with,for example,Vu+ or Octagon.
I ran an IQmonitor test at 27.5W and,as you can see,the app can scan like 6983 or 6903.
Regards
