Licensed amateur radio operators have increased form approximately 300,000 in 2970 to more than 700,000 today. Not too bad for a dying hobby. And these 'old timers', in addition to voice, are working using digital text, digital voice, EME (moon bounce), satellites (including ISS) and bands from 200 kHz to close to light to communicate.
But those 700K+ hams are not as active as they were even ten years ago. Hearing JT65 / FT8 on 7045 and 14045 24/7 is not ham radio. Sorry. A computer doing most of your contacts for you doesn't replace sitting down, keying a mic, or using a code key, and actually contacting people.
When I tuned the 20 meter band during the afternoon and evening of the 4th, a holiday, the band was amazingly spare of signals. There were 2-3 signals from Europe, and one guy vainly calling CQ from NZ, and none of those 700K+ hams in the US bothered to answer him. They couldn't be bothered, apparently, to sit in front of that expensive ham equipment and talk to other Americans or overseas people on a holiday. 20 years ago, holidays were popular times for hams to get on the air. Now? Nope.
20 years ago the 20 meter band would be
packed with hams, even on a holiday, because for many of them it would be a day off with no other pressing stuff to do. I used to DX the ham bands on my SW radios and comm receivers in the 80s and 90s and 00s, and I remember what it was like on the Fourth and other holidays. Even on non-holidays it's been nothing like the 20 Meter Band sounded like 10 or 20 years ago. All those hams aren't getting on the air. Even 30 Meters, which used to have at least a handful of CW QSOs during the evenings most nights, is dead, except for the odd FT8 that shows up and wipes out several frequencies of the band.
The Solar Cycle being a relative dud compared to 20 years ago hasn't helped, obviously, but we're nearing the peak (now projected to hit this fall), and the hams from the EU and NZ I've heard on the air recently don't have the pileups that used to be standard. Nothing like pileups in 1992 or 2002. Even the CW sections of the HF bands aren't anything like they used to be, when the entire swath from 14001 to 14050 or so would be wall to wall with signals.
And even CB sideband and outband is nothing like it was in 2011-2014 or so. I used to hear half of Latin America every other afternoon on 27455 USB, or a nearby calling frequency (in the early 90s it was 27295 USB). Now? I'm lucky if I hear a few Mexicans talking to Puerto Rico. There's a guy in Costa Rica that sounds like he has marbles in his mouth. But the rest of Latin America? Either the conditions aren't good enough to deliver the signals anymore, or hams in South America are on their computer instead.
But even if the solar cycle is weak compared to the past, there still are adequate conditions for hams to got on and make QSOs. They're just not doing it like they used to. They seem to get the license, get an Icom 7300, set it on a pretty desk, and then go do other things.
As for the Original Topic: It's sad to see Kranji go the way of the dodo. I used to hear the BBC from Kranji every morning in 2003, and a whole bunch of times in 2012 or so. But property is at a premium in Singapore. The island nation is growing in population and there is nowhere to expand. Even reclaiming land from the sea is costly. So it's understandable that Kranji is going away. AM stations in the US are seeing the same issue -- their land is worth more than the broadcast operation.
And there are other SW transmitters in Southeast Asia that the BBC can probably use.
