Does anyone in either country actually have an HD radio? Could you even buy one in Kiev or Santo Domingo? The reason I ask, isn't simply to be a wise guy; these types of countries are tough places in which to find decent receivers to start with. Even a Sony Walkman generally requires a trip to a specific shop somewhere downtown or near the metro area's fanciest mall. Most radios tend to be sold at smaller stores or by vendors and these units are at about the same quality level as a Coby.
Secondly, the prices that someone has to pay for such technology is between 30% and 50% higher than in the USA. So, even the Insignia portable (were it available) would end up costing around US$70 - a lot of money for the average Dominican or Ukrainian. Even if one could find an HD radio, the cost is high and value derived from that extra cost is limited.
So, my point is this: where's the ROI for the station owner? If nobody's listening and the outlook for growth is bleak, what's the use? Why bother? All I can say is that whoever is selling this technology internationally can clearly sell ice cubes to the Inuit. Or she's damn hot looking and doesn't mind fraternizing with the clients. Because there's no other explanation for this from a financial standpoint.
Meanwhile (to beat this drum a little more) smartphone sales are showing healthy increases in such cities as S.D. and Kiev. With smart phones come many, many audio entertainment choices that far outshine anything that HD radio can offer.
