Mikel Forcada EA5IYL on Nostr: Studying the 2-m and 70-cm repeaters I can excite every day from home (IM98ri99) ...
Studying the 2-m and 70-cm repeaters I can excite every day from home (IM98ri99) [that is, without the help of tropospheric ducting] I have found that about half of them are behind rather tall mountains; I suspect the knife-edge-effect or diffraction on the crests of these mountains is the reason. In the picture, a 1050-m peak (Penya del Salt de la Mort, EA5/AT-056) at ~40 km from my place is possibly the reason why I can reach a REMER repeater at Ardal (EA5/AB-032, 160 km) from home everyday.
