[Elecraft] K4 Remote Lives and Breathes!

[Dave]

Very interesting Rick, thanks for sharing the info.

One issue that seems to be increasingly common is that some (many?) ISPs no
longer offer a fixed IP address, which K4 Remote currently needs. The
system many ISPs are changing to is carrier grade network address
translation, it first surfaced in mobile networks, but is spreading to home
broadband too as ISPs run out of IPv4 addresses, see:
https://en.wikipedia.org/wiki/Carrier-grade_NAT

A way around this is with the use of a central server, which isn't usually
free. Remote TX works in this way but uses a Raspberry Pi. I note they
support the K3. https://www.remotetx.net/
