This raises an interesting question. If HD radio sales figures are that hard to come by, then how would anyone know with any degree of certainty the market penetration of HD receivers?
On the FM HD side, one could roughly infer the number of receivers from the HD2 and HD3 ratings (since these can only be received on HD radios), but for AM HD it would be much murkier. An up-tick in an AM station's ratings after going HD could be due to more people listening to the AM HD signal, but it could also be due to listeners preferring the program content (perhaps even in response to another station's programming changes).
