My 80m antenna has apex at just 5m from the ground and I can't hear even the local 80m SSB net on 3.6 MHz at 7.15 am with net controller at 5 km from here. Still it took my signals about 2000 km on 12m CW to @vu2tum. Wonder of harmonic resonance of dipole! youtu.be/XIZZzzYwzdo

My multi-band fan dipole antenna was not working after heavy rains. I was not able to get even local contacts on 40m, though the antenna was 'tunable' with auto-tuner in my FT-710 radio to 1:1 SWR. youtu.be/aYZXKblhqUU
All new Real Time QSO Manager from QRZ is now available for public beta testing. I had the opportunity to be an initial beta tester, thanks to the QRZ team. youtu.be/56rE86QaCYs

Onam is the most important regional festival of Kerala. Today I had the unique privilege of exchanging Onam Greetings through the @ARISS_Intl. I was extremely happy to get Onam Greetings through the satellite for the first time in my life! youtu.be/cHSy32QQojY
I have connected the 200 ohm impedance side of the DIY balun to the ladder line, presuming 50 ohms impedance of coax on other side. 50 ohms side was connected to the short piece of HLF 200 coax taking signals into the shack. youtu.be/P9HqMosUZns
A really complicated antenna for LEOs indeed! 73

Wow! Tremendous CW speed indeed. All I can understand without much effort is 5NN!

Got good SWR match with 4:1 balun on bench test with NanoVNA from 1 -11 MHz. So it should cover 160m, 80m and 7 MHz bands. youtu.be/VZecAjQn2Rc The final test is of course by connecting it to the feedline, between the ladder line and the short piece of coax!
