One thing I've noticed while operating digital is that I frequently see Cuban stations operating PSK31, but I don't think I've ever seen one operating JT-65.  Just curious as to why that would be.  Is JT-65 not an allowed mode for Cuba?

Its quite possible the computers they have are old and not fast enough. I've tried twice and failed with two different computers to have JT65HF work properly and with all the problems it created for me to transmit 13 letters I decided to stay where there's more activity, PSK 31

If those Cuban stations using PSK31 are sending 5 figure groups, they probably won't respond to any calls.   Grin

Internet connectivity in Cuba is heavily censored, slow, and expensive. Without reliable Internet, the average ham can't sync their PC clock with ntp. And if you can't do that, you can't decode, or send decode-able JT65 signals.

True, unless one is heavily connected to the powers that be and I rather doubt many of those are into ham radio.

Found a SW broadcast out of Cuba some months ago where they were building ham gear out of junked TVs.  Might explain some things.

I worked CO2OQ on 20m JT65 on 2/16/2011 at 1217 UTC.
