I added the ICE Model 400x after all my transceivers to quelch the BCB 
interference. This filter allows you to transmit through it as well as 
receive. The cut off is kind of high so 160 is useless, but I don't have 
space for a 160m antenna so not a problem here. My point should have 
been that the Jupiter was by far the worst of all my transceivers where 
BCB interference was concerned and that it wasn't useful for me without 
the external filter. This was NOT the deciding factor me.... it was the 
lack of a hardware noise blanker. The DSP derived noise blanker has no 
effect on my electrical noise here whereas the hardware noise blankers 
in my Scouts, Paragon, Omni-VI+, and Omni-C were very effective. I 
didn't find the Jupiter's DSP Noise Limiter particularly effective on 
this noise either.

What I did like about the Jupiter:
1. The ability to broaden the receive bandwidth for ragchew listening.
2. Extreme stability
3. Perfect bandwidth control for digital reception (PSK, etc.)
4. Software control flexibility
5. Internal antenna tuner
6. Remote keypad/tune control

My negative issues other than what I mentioned before were mostly 
concerning somewhat poor ability to function properly within strong RF 
environments (even its own under some conditions), the poor quality of 
controls and the Jupiter's somewhat weak-contrast display.

Oh, I have owned an RX-350 for over two years now which has virtually 
the same receive section as the Jupiter.... so I remain familiar with 
how the Jupiter works in comparison with my other Ten-Tec transceivers.

(I actually use my Paragon the most.... go figure).
