I am looking at the PL 990 also because of the SYNC working quite well in demos and good audio continued from the PL880 with refinements.
I am really looking forward to the SWling Review and report.
I am hoping the SYNC can be used on broadcast AM ( using either sideband ) then SYNC and narrow bandwidths to separate from other stations for some comfortable listening (not just a DX ' read ' of the signal but low static actual listening).
So IF the speaker can go a little crispier ( roll off low mids switch ) for voice than PL 880 and still have the bass for typical FM Music etc. ) and the 990X is a little more sensitive with a lower noise floor than 880 - I will order one if under $250 to $260 ...
No idea of price but it will need to be higher than current PL 880 prices right ?
I just tried out a Eton Executive Elite and the SYNC was surprisingly good , low noise floor a bit off alignment on USB compared to LSB and a bit low fi on the speaker- less bandwidth than Grundig G3 .
The Etòn also has 4 modes on the tuning dial to click through [ stop , fast , slow, and 10 hertz fine] Stop is redundant ( has lock ) and fast is available with the up down arrows .
The SYNC was excellent - I even fooled it into locking on a Non AM SSB HAM signal .
Hopefully the 990x will smoke all the portables so I don't need to try another Etòn.
