Last week an electrolytic cCapacitor had failed in a 70’s measuring device from HP (8445B preselector). The capacitor in question is a smoothing capacitor in the power supply assembly. It stopped smoothing, but shorted the whole supply out. Poof, fuse blown. Thank goodness for that! Not much time that day, so something for the next… Continue reading »

Later on, a separate licence became available without the Morse test and only gave access to VHF and up. My first exam was… Continue reading »

Although I read about the station several times and watched various YouTube videos, I never tried reception myself. On Saturday, I tested a number of wire antennas that were connected to a USB sound interface,… Continue reading »

The first location was abandoned because of blocking trees. The latter location was on top of a school building with a superb take-off. We… Continue reading »
Below, an annotated picture of my antenna setup, taken in 1992 (click on the photo to enlarge). Some years later, I moved to a different QTH and unfortunately, I did not have the opportunity to put up the mast again:-(
Have a look at some of the QSL cards received from stations who were permitted to transmit on 6 meters. I could only listen or talk back on 10 meters. At the time, most 6 meters stations listened around 28.885 MHz. Conditions were so good, that I could hear European stations via backscatter on 10… Continue reading »
