I haven't tried but I will. In my opinion the level of the signal and the gain of the antenna won't be enough for the receiving but I think to change the LNB with LNA with NF 1.2 or 0.8 db and to try how it receives IC R20 directly on the frequency 2401.200 MHz.
For antenna I use only feed from 0.6m dish on 2.4 GHz from i-net link. The gain of similar feed is not more than 3db.After that I put LNB from 2.3-2.7 GHz with LO 3650 MHz.AO51 transmits on 2401.200 MHz and the IF in this case is 1248.8 MHz.This freq I give on my scanner IC-R20 which is set on FM. For supply of the LNB I use splitter from sattv and an accumulator(12V).On the other hand I had a problem IF is changing from V of the power supply and is not always the same in different supplies.
Superp!!
Did you try without converter? R20 reachs 3305 mhz.

A very good receiver but is necessary a filter notch 88-108 for low band vhf good luck ciao 73 IK4MEE Italy
