 I am not sure what the previous post is talking about, but...The TS520S is
 the best one. The 520 is the original, and does not have 160...but it does
 have the dc-dc converter built in...if you want to use it mobile (??)
 The SE was the last version, but I am not sure what were the diff's there.
I
 don't think it had the heater switch....
 I have a 520S, and it will go down as a classic. Still has better sounding
 SSB than say a 756PRO!!

  Hi,
  ?? never heard that they doesn't work on 160m...
  Other proof, the antenna tuner is preset to match 18 sub-bands between
1.8
  and 28 MHz
  Of course they work on 160 meters, as any good RTX !
  but maybe not your antenna... Hi !

   I've seen some of these (only on the net) and have become interested
in
   maybe purchasing one in the future.
  
   My question is: which model is the best? Other than the fact that the
 520
   has no 160m band (I believe this is correct), what are other
 differences?
  
   Thanks!
