At first, I was just looking around on the web for some simple Rules of Thumb that compare the weak-signal performance of commonly used analog and digital modulation types. I was mostly focused on FT8 and FT4 but I also wanted to compare SSB and CW. I failed to find a simple compariso...
It was only when I discovered that my vertical was causing lots of EMC problems with my neighbours, whilst my horizontal half wave dipole antenna at 30 feet was not causing any problems at all, yet giving a better signal in Australia, that I realised that it was thevertical polarisationthat...
