Tyler-Think about a 10 meter full wavelength loop inside 1/2 inch pvc laying on your roof. I used one for many years on rs10 and 15. A little more gain and less directive than a dipole. The length will be 1005/F(mhz) 73 Bob W7LRD Seattle -------------- Original message -------------- From: "Tyler Harpster" <tyler881(a)adelphia.net> > I just bought a 10 meter preamp from Advanced Receiver Research.

Loads of operators, falling over each other to use a satellite? In some respects, is that not a good thing? Jules

How in the world is is even remotely possible that people hold a conversation on the bird knowing that there are 70 people ( probabally more like 170) using the bird for quick contacts? HOW IS THIS EVEN POSSIBLE.. I cant imagine the ignorace involved... I just cannot fathom it. -Steve Raas N2JDQ FN20vg

Ib: I'm completely agree with you and thanks for your warning. I feel very ashamed by the behaviour of this spanish users: taxi drivers, hunters, couriers..... as you have noted they are not licensed operators. We have to suffer them most of the time on 2m band, not only on satellite segment, but SSB and even EME segments. If you ask them gently to stop transmitting on the band you can receive bad words and threats. Despite the individual or even group complaints to our "FCC", the spanish administration seems to do nothing. At Madrid, we have even the "inhibitors" noise just in 2m and 70cm bands (sorry if the translation is not good, I mean those transmitters used by the security forces to jam wireless devices). I know, as QRP sat user (whip or arrow ant with a TH-D7 hanheld), that get the sat with such a low power and in competition with QRO stations under norma circunstances is a real challenge....., but struggling with these unlicensed jammers goes far beyond the QRP spirit. If PL tone could help to avoid these troubles, I please the AO-51 control team to activate it if is posible. I'm sure this suggestion will be wellcome by most of us. Thanks again and please count on me for anything I may help.
