Same thing over here especially for some CW station who crank up their power until they hear their own downlink and they start to call CQ 
using the same power level. 


Those using just enough power have to increased their power too until the pass band became unusable. Even with the lowest power setting on 
some rig the EIRP is still too high. A way compensate they should stay off pointing in elevation this will help reducing their signal at 
the satellite.

It is not an easy concept but the using "just enough power" as stated in many radio act and regulations take his full sense on satellite 
operation. It his hard to condemn when the operator is at his first qso's but when "veteran" are involved it is a bit hard to understand 
their motive? (Just remember the chirpy CW signal on HF in the past some station get tag as the always chirpy one!) 

Just to pointed that on AO-7 on August 28 i was able to have a QSO with F2IL Jean-Marie  the satellite is in the best shape since a long 
time no more heavy distorted audio. I was trying the double sat FO-29/AO-7 idea but with not too much success. It is hard here as per my 
simulation to have both satellite in range but european pass offer many pass where both sat are in range over the same area.

Who will be the first! we have the labour day week end here to try this concept.
