Wednesday evening 6.7. bought the strongest opening so far this summer. Unfortunately the condition area was too large. At the same time whole Europe was coming up, only Turkey and UK were out! FM-stations from 25 countries at the same time! Lasted 4 hours (last 2 h were mostly Romania).
On most of the frequencies were 10-20 stations pushing up at the same time from almost every European country. This kind of situation gives white noise, dozens of stations are fighting on one frequency and the result is only noise (receiver's signal meters are peaking on highest level all the time but you hear only noise).
This opening was not the worst I have expereinced. There were still some high-power transmitters up and audible, but stations were changing all the time on one frequency and were very difficult to id. Less than 1 kW stations are mostly not audible because highpower transmitter from some other country blocks the channel.
Also RDS-signal-ID is useless during this. Usually during white noise-opening we do not get RDS-signals out because stations interferere each other so much. Strong signal from the same or adjacent channel blocks RDS-datas.
