Hi all,
I have a coupling problem in my station when trying to work FO-29. My 2m signal is completely blocking the 435 MHz downlink, and so I can't hear my signal off the satellite. I guess it must be something related to the distance between the two yagis. (I use the terrestrial horizontal yagis you can see at http://www.dxmaps.com/jm19hn.html ). With mode-B satellites there is no problem. I have tried it with two different 435 receivers, and it's exactly the same.
Anyone has had this problem o have an idea of the possible reason? And what is more important, of some way to solve it?
Thanks for any possible help.
