Ignore my previous post on Satellite Internet

[Don Strom]

DSL internet is available at my remote site.    It is only 10MBPS  speed.  

I believe that is the minimum speed for remote radio so might not work that well at that speed.

Don,

bandwidth is not the problem, you can run a remote reliably on a 128
kBit/s connection (been there, done that). The problem with satellite
internet is latency! For remote you want to stay below 100 ms RTT (round
trip time), better yet below 70 ms for a smooth experience. With
satellite you're talking about > 1 sec RTT which is just unusable for
remote.

My experience is that the biggest problem would be jitter. Oli is correct that you can operate RC over a 128 kbps link. But you can also operate RC over fairly high latency links - it wont give you a "smooth" feeling when tuning across the band- the VFO dial will seem to be connected via a rubber band. But it is something you (some at least - and I for one) can adapt to. I have tried it extensively over the years, started using RC over 10years ago. I would not call it unusable if the alternative is nil. If you have alternatives its another matter. I have QSOed with this iPad from a Norwegian flight (from EA8 to OZ) and while it was not too "smooth" it was definitely useful and a lot of fun.

But if you have high jitter it is my experience that RC does not work satisfactorily. At least the software must be written with high jitter in mind. If not, the software may drop out frequently driving you crazy and its my experience that VoIP based on TCP/IP will not work well.

My guess is that with a 10 Mbps connection you are likely to have low jitter and you will be just fine. Your XYL can enjoy streaming video on the same link with no problem and you wont have any "local QRM" during your QSOs. Have fun!
