Hi Bob
I can reduce my Yaesu FT-736 10 watt output to 2 watts and still get full quieting on AO-51. I have an array of 4 x 27 turn helix fed with 35 feet of 5/8 inch hardline. I have tried the 10 watts into a single 27 turn helix and as expected it worked as well as the 2 watts into the 4 x helix array.
On AO-40 I seldom used U/S as the L band array worked so well on mode L/S for hundreds of QSO's.
See March/April 2004 AMSAT Journal for pictures and construction details of my 4 x 27 turn helix L band array.

Hello I would like an informal survey regarding what you are using for Mode L. I am working on my system and do not want reinvent the wheel. The format of radio-power-transmission line-antenna/gain. I use a IC-1271A-10 watts-50 feet LMR400-12T helix about 12 db gain (or so). I need to improve my system and as usual your advice is invauable. Perhaps several on the list could benifit from this. The current AO-51 in L/S is an excellent chance to fine tune my system. 73 Bob W7LRD Seattle _______________________________________________ Sent via AMSAT-BB@amsat.org.
