 uplink FT-221R-HB-TRVTR-2C39PA 15 turn Helix 
 downlink 30 turn Helix DB6NT preamp at feedpoint, DB6NT -TRVTR FT847

 here are the results from last night operation via LS-mode

 conclusion : the 1269 MHz-uplink seems to be more sensible to the squint and
              distance than 435 MHz  - as theory predicted -
               Many uplinks on 435 MHz are at the same strength during the
               listening period. My uplink signal become weaker and weaker.
              Hope that my frequency conversion table can help a liitle bit.

 Now time to go to office
