Experiences with SSDR 2.0 and remote operation

Hi,

So Flexradio finally came out with V 2.0. Bummer that I have to pay for this (after all, the thought of remote operation of an SDR was the single reason that I bought my Flex two years back, but due to poor performance over ADSL and VPN I've been stuck with Icom/Remoterig).

Of course, this makes me wonder: Did v 2.0 really bring any performance improvements to the table, compared to v 1.x when it comes to operating remotely? I am not talking about user friendliness issues (like getting away with VPN), but real improvements, such as reduced bandwidth requirements etc. I've skimmed through the manual for 2.0, and find no real numbers in this area.

Are there any significant convenience features (except no longer needing a VPN) that applies to remote operations in 2.0 compared to earlier versions?

Thanks,
Bjørn

Hi Bjorn,

I have found V2 to have superior performance to a VPN setup and is much easier to setup and optimise especially on a low bandwidth link.

1 - A VPN setup will put all the traffic from your remote device through the VPN unless you setup tunnelling to only allow applicable traffic. (Easier said than done and I failed to setup) This is especially bad on an iPhone where lots of other traffic is continuously occurring. 

2 - I can run on my iPhone with <30 Kb/s data rate measured. ( In fact iPhone 6s CPU load is bigger problem). 

3 - My VPN was on my computer which I could not remotely start / stop quickly and easily. V2 setup with my wemo device switching the flex lets me operate perfectly.

I have a lot more to learn and optimise but so far V2 has proved great for me operating from within the UK and my son from outside the UK. I might go so far as to say I am impressed :) but I will hold back until I have tested it harder.

I also begrudged paying the $240 but I am glad I did!

I have made some measurements on my iphone with differenet setups and will post the results on a separate thread rather than hijack this one.
