Western Asia? No, places like Georgia, Turkmenistan and Azerbaijan. Those are small countries likely with little access to mass media in rural areas.
And how about places like Burundi, Malawi and Uganda? We're still sending aid and money over to starving children in Uganda. That area might not have that many FMs either -crainbebo
A brief glance through a recent World Radio TV Handbook quickly reveals that those countries have lots and lots of FM stations, and the WRTH doesn't even list them all (often leaving out low power operations.) Decades ago your assertion might have been true, but no longer.
Shortwave radio is disappearing because, outside of a few very specific areas, the audience has vanished. Local FM relays, satellite TV and The Internet are the replacements. Plus governments around the world are under tremendous budget pressure, and international broadcasting is a prime target for cuts.
I've been a shortwave listener since the mid-1960's. Sad to see most of it go, but I am also a realist. New technology and shifting listener preferences have forced change. See the demise of AM Radio in favor of FM, then the assault by online audio media.
BTW, it appears the shortwave demise of Radio Exterior de España has been pushed back by a few weeks. Lots of confusion at parent RTVE about the organization's future direction.
So pretty much RNW will be defunct worldwide? Gosh, I can't imagine SW radio by 2020. Let's hope that WRMI, or WWCR, or WBCQ gets some relays of the international broadcasters. Did you know the 9955 WRMI relays Radio Slovakia International? Maybe they can get Exterior de Espana, and BBC World Service, and others, instead of jesus broadcasters.
The last vestige of RNW radio efforts (the "El Toque" program) had its last SW broadcast on August 1. RNW is now gone from SW.
The American shortwave broadcasters you mentioned are private commercial stations that sell airtime. WRMI has a few international stations as part of its programming, but I suspect most of those are unpaid public service filler, presumably to juice whatever residual interest there is in shortwave listening. For any extensive relays, the time would have to be paid for, which probably is not going to happen. As with AM radio, the religious broadcasters don't care if the audience is tiny to nonexistent, as long as they can "get the message out." And as long as the checks clear, the private commercial stations don't care if the audience is tiny to nonexistent, either.
