There are many folks using their FlexRadio's over the Internet using a VPN solution. FRS will get to WAN support as they are able.
In the meantime, you could either use a VPN solution or buy an Icom if that is your preference.
The world is full of choices - some do, some don't, others complain.
Enjoying operating my FlexRadio remotely from all over the world via the Internet.
It will interesting to see if the 7300 can transport IQ data with the panadapter information. I have a 7800 and in order to view the panorama ala Flex I have to piggy back an SDRIQ receiver. I much prefer the Flex. Using a mini computer, VPN probably will never be any worse than direct WAN connection to the Flex. In any event, these are exciting times watching the paradigm of amateur radio.
I just went to the Icom site and see that V 1.90 just came out which provides graphic data. It mentions a new USB 3.0 driver must be installed. I am not sure what this implies. Using USB just tells me the graphics data will be available locally to the user but not over the Internet. However, that doesn't mean one could not equally well use VPN on the 7300, also.
Also, I would imagine that this solution they are providing will work more like RemoteRig, and much so less like a WAN based SSDR client with audio and IQ data transfer, etc. Personally, that wouldn't fit the bill for me being a big digital mode guy.
I can imagine your frustration with regards to promises on what a radio will do not only now but in the future. I'm sure I will get a lot of heat on this comment, but here goes. I never would buy a radio on the hope that it will do this, or won't do this, especially when it is controlled by software! Promises don't seem to be valued anymore. Promises have become like the politicians. 9.9 times out of 10, they never keep them. And yet the people are foolish enough to believe them and vote for them. Mark Griffin, KB3Z
