[Premium-Rx] WJ 8716 manual

[Geoff Greer]

Hi,

  Your receiver could have a bad 1st mixer. The mixer is esentially connected directly to the antenna.  This 
particular mixer is a bit unique is that is used with a very high level LO (+27 dBm if memory serves me correctly).  
The last time I bought one of these mixers the tab was around $100.00.  This was 3 or 4 years ago.   There 
might be a more reasonably mixer available now.

Regards,
Geoff Greer
