GQRX with upconverter question

[Tom Sevart]

Hello,

I've just started using Gqrx with my RTL dongle and 125 MHZ
upconverter.  I have figured out how to receive VHF/UHF OK, but what I
need to know is where to enter the 125 MHZ offset so that I can listen
to HF with it.  I assume it's the LNB LO box in the Input Settings tab,
but I'm not sure.

Never mind, I finally figured it out.  I learned that I needed to put
-125 MHZ into that box so that the display would read properly.  When I
was just putting 125 in there it kept showing the frequency as 125 MHZ
too high.
