[TenTec] ORION 1 upgrade to 2.063xg

[John Chance-Read]

I have successfully upgraded the Orion 1  - thanks to Walt, Rune, Billy and John's helpful hints.
Initially I still couldn't get the instructions I wanted but after trying a previous upgraded, which gave those instructions, I then found that 2.063xg also gave them -  it was so easy - brilliant.
I note the following changes on the spectrscope (a) there is no longer a choice of bandwidth (b) the difference between noise and S9 is a considerable clearer display (c) use of the PreAmp noticeably changes the height of the display.  
Question - is the Spectrum Scope now sensing further up the chain.  I understand originally it was only looking at the signal into the RF stage ?
Are there any other significant changes ?
Thanks you all for your help.
