I concur with the other comments made about Collins audio; however, consider 
this:  Most of the bragging rights about the "best of the best"  in 
receivers includes an R-390 or R-390A.  When you talk to those 390 guys you 
find them pulling off the audio at the detector, which is a standard feature 
of those receivers.

I have a Collins R-388 (similar to the 51J3) and I bring the audio out of 
the detector and into an external amp and I think it does fine on AM.  Is it 
one of the best AM receivers, of course not; but sometimes you just want the 
look and feel of a certain receiver and you can compromise on certain 

I also concur on the general coverage version over the ham band only, but 
again, it's a personal choice.
