[IRCA] warble jammer on Cuba?

[Mark Connelly <markwa1ion@xxxxxxx>]

The frequency "wobbling" originates at the Cuban stations.

It would seem to be intentional rather than just being a result of 
poorly-maintained equipment.

This has been noted at different times on many different Cuban stations 
including those you mentioned, plus 870 and others.

Maybe it's to increase interference to co-channel US stations (WSM-650, 
WAXY-790, WWL-870, etc.) that could otherwise be heard "backgrounding" 
the Cubans' audio.

Of course it could just be unintentional technical incompetence and old 
broken-down '60s-era low-quality Commie transmitters instead, sort of 
like those perennially off-frequency Albanians.

Here on Cape Cod, Cubans dominate on many channels at night especially 
if I'm running the null-north cardioid pattern SuperLoop or an ordinary 
loop nulling E/W.
