Mike Radio frequency change

This week we changed the antenna system from Mike Radio (NL). We finally succeeded to change the 31 mb antenna into the 41 mb. The frequency is changed from 9.290 into the range 7.5.80 till 7.630.  This means Mike radio can be also heard again in western europe! The antenna works super. The impedance of the antenna is for the working freq. near perfect. Also in 40 mb (ham) the antenna/reception works fine. All QSO (opposite) stations can be heard easy. This morning from the east-USA (nice) receptions of ham stations even when conditions were not that good. The antenna is the inverted V, top on 14 meters, one leg is to the west, the other leg is now more or less in the South East direction (mid/south Germany), the V has ca 120/130 degrees angle. So good news for the next winter-season. This summer we make a homebuild vertical for the 19 mb, the band where conditions next years will improve.
