Richards,

I almost agree with Al's comments.  I have both a black/blue and  gray/green 
Jupiter and 
have mixed opinions on the screen.  I don't prefer the blue screen enough to 
spend the 
money to upgrade my green screen.

My Jupiters have the CW keyboard/CW reader upgrade and I never use it even 
though CW 
and data are all I do these days.  Nothing wrong with them, just no compelling 
desire to use 
them.  Money I should have kept in the kitty.

There are two factory approved modifications to the older (read earlier 
gray/green) Jupiters 
that I performed.   (this also applies to the Pegasus)

1 - Removed a resistor in the audio chain to increase the available audio 
and....

2 - Replaced a 1uF capacitor with a 2.2 uF capacitor to improve the ALC action 
on SSB 
transmit.

Those two mods involve working on circuit boards with which you may be 
comfortable or 
maybe not.

Neither of the above mods are really necessary, just tweaks for most cases.   
In my case the 
resistor mod is quite useful as I am nearly deaf and the increased audio is 
helpful.

According to their web site, Ten-Tec still sells the autotuner for the Jupiter. 
 If you are not 
comfortable getting inside the radio with a soldering iron I'm sure TT would be 
happy to install 
the 'tuner and at the same time do the two mods mentioned.

Of course....all of my suggestions may already be in place in the radio you are 
getting.   :-)

Have fun.  

I have an up-to-date Orion classic and I use my Jupiter or Pegasus most of the 
time.  Very 
nicely balanced radios in my opinion.

73,

-Lee-
