If I had one for 25 years, could *only* get AM on it, and used it only 
for chewing the fat, *I'D* consider getting another radio.

Then again, *I* do change bands.  I've aligned mine after removing the 
old paper caps - called the BBODs.  The '67 EAC that WAS here 
consistently, and got 0.5uV sensitivity across the board.  I swapped it 
for an SP-600 - *ONLY* after getting a '51 Collins R-390A to make sure I 
still had one.
(Pssst - I found out about the 0.5uV sensitivity because I was using a 
General Radio GR-1001A signal Generator.  When properly terminated, and 
set at 1.0uV - it is *really* 0.5uV at the antenna.)

But I also *communicate*, not simply contest.  CW, SSB or AM makes no 
difference.  The filters allow change in bandwidth.  Is it a Band 
Cruiser?  NO.  It *never* was meant to be.  Guess I'm just NOT an 
appliance operator.

First rig was an SB-102, SP-600, & PS-23.

As soon as my local club in Georgia held an auction - so it could put a 
TS-520 in the city Emerg. Opns. Ctr. - I bid on and won the HT-32 
SX-101A. So split opns and the hassles of two pieces to operate and 
syncing them became second nature.  I've worked pileups from Korea, and 
all over the world that way.

Different strokes!
