Those were the days! I first discovered S radio on my sisters old tube (valve) radio - don't know the make or model. It had a broken tuning scale, so I had to put my hand in the back and tune blind. The number of times I got a shock from the HT line when I wasn't careful, I can't count. I remember, though, catching some gems. Radio Madagascar, Havanna, Tirana, Budapest, Bucarest were some I remember. I didn't ask for QSL cards because I had no idea what frequency I was tuned to. That must have been around summer 1973.
It wasn't until the following year when I got a pocket radio for my birthdat and discovered MW radio proper. I had, of course, listened to Radio 1 etc. but one day I came across a strange station in English I had never heard. It was RNI (Radio Northsea International). It was afternoon when I first heard it but that got me thinking - what else is out there? The rest is history, it set me on a long-time hobby of hunting for stations that few in my town hwd wcer heard of, let alone listened to. Happy days.
I do feel disappointed for those just entering the world of DX. Yes, there are still gems to be found on SW and MW, but with all the noise from WiFi, washing machines and - the bane of my life; fridges, it is a much more challenging hobbie than it was back in the day. I tend to hover around the lower broadcast bands - MW, 75, 60, 49 metre bands and rarely go above 31 metres.
I now have a number or receivers but, not being as mobile as I used to be, stick mainly with SDR, occasionally using my QODOSEN DX-286 or XDATA D-808. I use an ad-hoc antenna - just two long wires for ant and ground about 22 metres each, which serves me well.
