I use the 910 with one of the KJ6KO 60 watt amps to 50ft of lmr400uf, and a m2 35 element yagi. Circular would be better, but I also use the antenna system for terrestrial SSB work. Fine tuning the uplink is very important on L band. Due probably to radio inaccuracies, and maybe on the spacecraft, I have to offset the uplink by about 3 khz.

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!
