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 […] 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 […] 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 […] This is my umpteenth upgrade to the TX antenna to try to get better general performance and get the possibility to work on 136 kHz without tons of electrical wires outside the terrace. The new layout is drawn in the next basic picture: I’ve passed from 4 top wire and a single vertical […] Since my antenna was born as monoband for 630 meters, until today I’ve used an autotransformer built around the variometer. In these days I’ve tried to tune the antenna on 136 kHz, beginning to put some mH over mH to reach my goal. Arrived to 136 kHz I’ve sadly found that the autotrafo […] To make a clean sweep of spagetti wires on the bottom of the antenna, to make my XYL happier, i tought to use the aluminium strip for the first section of the TX antenna. After removed copper wires I connected the variometer to an old 4 el triband yagi for HF aluminium boom by a […] In the last weeks I’ve tested a new antenna for 630m band. To have also something usefull for 2200m I’ve built an helical loaded vertical antenna followed by a 3-wires hat, so to have a longer radiator that resonate about on 350 KHz. The coil was about a 45 meter long 3 cm aluminium […] Tonight was the second night for my new 630 meter antenna test. Thanks to the increase of Lowfers fellows I’ve had the possibility to have more receivers that last year. I’ve been listened by about 40 different stations in more than a dozen of European country. This image is relative to the night between […] 
I’ve decided to write some notes about my (little) condo experience in the MF world because many people think that We need a lot of space to work these frequencies. Today I’ll write about my TX antenna. It’s a classic inverted L, it’s only 9 meters high and it has an 11 meter […] |
