Hello Rik,In message <[email protected]>, Rik Strobbe <[email protected]> writes Why would one need an "antenna farm" with an ERP (EIRP ?) limit of 0.1 Watt? I think it's because small/low aerials lose more signal to surrounding ground clutter than do big/high aerials. I don't believe that trees, buildings and hills necessarily appear as part of the loss resistance you mention. On the other hand using narrowband modes will give easily give a 5 to 10 dB improvement of CW. Nobody disagrees with you. What Mal said was "there is no need to use QRS to be heard around EU". It seems a shame to use a slow mode if a given path supports a faster one. -- Cheers, Alan G3XAQ [email protected] |
