For those who are concerned (Internet linking to HF)

Apparently more people are concerned about this that I had realized. So,
for brevity, here is the text of the message I sent to John Hennessee, and
his answer to me. Please don't slay the messenger! (Me!)

My inquiry is at the bottom, and John's reply to my inquiry is at the top.

73, -KR4WM

(ARRL-related SPAM removed for brevity.)

I suspect he misunderstood your question.
It loks like the answer was about a VHF to HF link with the Internet in
the middle. The problem there is the VHF and HF mix, not the Internet
link.

The FCC has written opinion letters that specifically say that "remote
base" is not defined for them, and is an amateur invention, and that
their concerns are proper operation of the station and proper use of the
spectrum. The FCC doesn't care about the Internet for control links.
They just require that you properly control the station.

You cannot use ham frequencies for remote control except as you note,
but the FCC is likely changing the restrictions to allow 144MHz control
at the request of Kenwood. Part 97 specifically defines non-ham radio
links as allowed, subject to the other requirements of control link and
to the requirements of that service.

Internet control of an HF stations is OK, as long as you can fulfill the
duties of a control operator. If you are 6 inches away ot 6 miles away
from the antenna, they don't care, as long as you are able to fulfill
the duties of control operator.

If internet control of HF were not OK, then Echolink would be ilegal.
And the ARRL knows about E.cholink and supports it.

If internet control of VHF were not OK, then IRLP, would be illegal,
ditto.

What you can't do is use 2M to control your HF rig, at least not yet.
You can use UHF though, as long as you can control the rig and prevent
unauthorized transmissions.

Re: For those who are concerned (Internet linking to HF)

Exactly correct Leigh, and very well put. In our area we have been doing
remotely controlled base stations since the early 1970's. The control has
always been done at UHF but the remoted stations have essentially been DC to
light in various applications. Now we are developing our own controllers
which will perform the legacy UHF radio control inputs PLUS control via IP
based networks, both private AND the WWW.
