Has anybody had any experience with this?

Curious to see if I can pick up anything on H 8/9, so would need to get a ka-band lnb and retune the LO to go down to 18.1 GHz, the lowest one I can find is a inverto which has an lo at 19.7 GHz.

Like in theory I know what needs to happen you open it up connect it to a oscilloscope start tuning it.

Just wondering if anybody has ever done anything like this.
