[Premium-Rx] WJ-8711A Upgrade. Hopeful or not?

[Pat1McA at aol.com]

Greetings All,
 
I would like to upgrade my ver.03.02.00 receiver which has some minor  
operation bugs. For example, when recalling stored channels it recalls  stored 
"slow" agc settings as "fast".
 
It has the "old" pcb in it and (ideally) I would like to take it up to  
ver. 04.01.03.
 
If you don't ask you don't get and I just wondered if anyone might be able  
to help please?
 
It is a shame that no one produces a modern direct sampling/SDR receiver  
with a real genuine "hands on" front panel as intuitive to use as the  
WJ-8711A. Or have I missed something?
 
Please reply off line and many thanks,
 
Pat  G3YFK
