Hello Jim
I use a 910 on L band, it drives a KJ6KO amp at about 60-70W. This goes through about 17M of LMR400, so I am loosing a few db there. Antenna is a homebrew 16 turn RHCP helix. I should try AO-51 without the amp, just to see what happens. I'll send you picture in a separate email.

Hi Folks,
I would be interested to know if anyone is using an ICOM 910 with the L-Band module for Ao-51 uplink on the BBS? (The optional L-Band unit for the 910 runs 10 watts according to the book).
I am particularly interested to know what type/gain of antenna I would need to get a reliable up link. I am planning to use about 20 metres of Ecoflex 10, which will introduce a loss of something like 3 Dbs.
I know that the LBand/Digital up link is currently off, just gettting ready for the next 'on' period!
