K3-0-mini / K3 dilemma

I have been working with a retired doctor ham friend of mine who has
moved into an assisted living facility. He has been licensed and active
for more than 40 years.

He wanted to be able to use his K3 remotely and I had helped another
friend of mine who is blind and is also a long time active ham get back
on the air from a condo using the Kenwood TS480SAT -Remoterig RRC1258set
implementation. This approach has worked for nearly 2 years without a
hitch.

I suggested to my doctor friend that we should test whether it would be
possible to operate remotely from within the large facility where he
lived. So we met with the IT staff there and they had no issues and
showed that his apartment had internet already installed. Before we
ordered any equipment I borrowed the TS450SAT control head and Remoterig
RRC1258-control and tested from his apartment at the assisted living
facility and it worked perfectly.

On the strength of the testing we ordered the K3-0-mini/K3 Twin package
from Elecraft. After getting over the shorted cable that goes to the
ACC jack on the K3 and a dead power supply for the mini I successfully
tested on my LAN and also from several other remote locations. We then
unsuccessfully attempted to operate from the assisted living facility.

For more than a month now we have been communicating with Microbit and
Elecraft K3 support trying to figure out what the problem is.
Additional tests with the TS-450SAT continue to operate perfectly from
the facility and testing the K3-0-mini from several other sites out side
of the assisted living facility also work perfectly.

Working with the IT staff at the facility we are convinced that there is
a difference in the packets being generated by the Elecraft and the
Kenwood but I have not been able find any documentation to help identify
that difference. We feel certain that the internet server at the
facility is finding something suspicious in the Elecraft packets that
are not present in the Kenwood packets.

Has anyone else run across something like this?

John, AD4S

Re: K3-0-mini / K3 dilemma

I'm just spitballing here, but could the net connection there be double
NATted so that the rig can't see the packets returning (since they have a
different address?)

Packets are packets. I had this problem - loss of connectivity - albeit
with a media server in my house that I wanted to be able to hook to
remotely. I called my ISP who pinky swore that they were not double
NATting the address. I did some digging and logged into my cable modem and
sure enough, NAT was turned on (which meant there was one translation in my
router, and one more in the modem.) Double NAT. Turned it off in the modem
and bingo, the server was visible to the world.

I'm hesitant to tender this solution, mindful of the old saw that "if the
only tool you have is a hammer, every job looks like a nail." But at
least it's something you can eliminate and it might be good for thought.

Re: K3-0-mini / K3 dilemma

Another idea is to check the port settings on the router to ensure the port that Elecraft is using is “open”.

Re: K3-0-mini / K3 dilemma

In reply to this post by John P. Cummins, Sr.-2

Not knowing much about the protocol Elecraft / Microbit uses, or the IT
staff at the facility, I have doubts about what is being done to figure out
what the problem is. There are tools, such as Wireshark to look at the
packets as they flow through or don't flow through the network. You don't
have to guess. It is likely that some firewall is blocking the packets,
either outgoing or returning. Firewall rules may need to be set up or
changed. Microbit looks like it requires port forwarding for ports
13000-13002 and that must be done in any routers in the way. If they are
doing double NAT on two routers, both will have to get port forwarding set
up. A good IT person should be able to figure this out with the right tools.

All that being said, I don't like port forwarding. I created an incoming
VPN that can be connected to from outside my network using OpenVPN. There
are issues with various firewalls letting the VPN through but if they
connect, the remote device looks like it is on the local network and
everything works, and is encrypted end to end. That is not easy to set up
though.
