That's what is so great about the hobby.

That's clearly an individual choice .. but from a non-RTTY/*TOR 
fanatic's perpective, FSK is a control technique -- not a mode.  The 
guy on the other end won't know and won't care whether your 
mark/space line shifts a physical oscillator, keys a digital AFSK 
generator inside the radio (common), or is accepting proper audio 
tones from an AFSK-capable TNC or sound card.   They all result in 
precisely the same transmitted signal.  That's my only point.  The 
distinction is pretty fuzzy ...

The display is a solid state panel, not a CRT.  The display is 
excellent, crisp, clean and meaningful.  Color would add nothing but 
sales glitz and maybe make the owner feel superior.  Maybe if I'd 
ever seen any of the current crop of radios that use color, use it  for 
anything but good ad copy I'd look again.   

There was a lot of whining about this many months ago.  I don't see 
it as an issue since the display is as good as it is.

I tried to find some info on the QRO website about their keying 
technique .. but couldn't.  I'm still confused, but since I'm not a 
professional, it isn't surprising :-)

It is not necessary to use the TX EN line (keying loop) with the 
Tentec, even with QSK.  When I initially had questions about 
interfacing my AL-1200 to the Orion, I got several suggestions, 
including the fact that single line (no handshake) keying would work 
quite well in QSK.  I jchose to use the loop becasue it's there, but it 
appears it isn't necessary (in many cases).  Might be worth talking 
to QRO about it.  I find it hard to believe that they wouldn't have a 
good solution -- especially since so many Ten-Tec owners are CW 
ops, and use QSK amps.
