On the night of February 14th my first TA of 2018 on 630 meter band. In the same night my first two USA stations have been received at Ripoli remote station with call IK0VVE/0 During last holidays in Croatia I made a photo about a Marconi-T antenna in the village of Kakma, here the photo: The antenna consists of a pair of towers about 20 meters high with a 2 wires Marconi-T antenna. Under the vertical wires is there a little house where the transmitter is […] This morning, until about 1 o’clock pm local time, I tried to increase the transmission power from 50W to about 180W to see if the homemade radial matcher commutator can resist or smoke… Well, it endured! During the tests i’ve been looking on wspr.net page and with a nice surprice I’ve seen that my signal […] Last night I’ve been transmitting for the first time after the summer period. A new look to the the TX antenna was made to simplify the shape and get more gain. Now the hat is about 16 meters long and the vertical side is about 9 meters high. The 6 wires of vertical slope are […] Tonight I’ve decided to try QRSS on MF and while I was transmitting I’ve seen on DK7FC grabbers a strange signal between mine and IK1HGI’s. The call was C7MW which prefix is allocated to the World Meteorological Organization. With Stefan’s RDF spectrogram is possible to see on the next picture that signal comes from E/W direction. Any […] Just now my U3S transmitter is blocked in TX condition as is possible to see in the next picture: DK7FC grabber The continuous line over 475.740 is my signal more than one hour long. The problem is that it was an unmanned operation and I’m not at home now. Strange […] Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km mi 2016-09-27 02:40 IK0VVE 0.475692 -29 0 JN61km 0.05 WD2XSH/17 FN42pb 6626 4117 […] Finally my signal came out from continental Europe reaching Iceland. 44 stations copied my signal and 3 times TF3HZ received my weak signal: Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km az 2016-09-19 22:16 IK0VVE 0.475774 -28 0 JN61km 0.05 TF3HZ HP94ad 3355 330 2016-09-19 22:08 IK0VVE 0.475775 […] Last night was my second “serious” TX test on 136 kHz, transmitted Opera32 mode after an upgrade to the matcher. To tune the antenna on 136 kHz I’ve build a couple of inductors over two hand cleaner soap bins. The first one was wound with enameled copper wire of about 1 […] |
