§97.213 Telecommand of an amateur station..... If radio, the control
link must use an auxiliary station.
This says it all. A control link for controlling a repeater by radio is
an auxiliary station. Also in 97.201 the freq coordination for Aux
stations follows similar to repeaters. If interference the coordinated
aux station has preference over non-coordinated.
Maybe SERA is stating they are not coordinating aux stations or not
coordinating aux stations on 2 meters. Maybe they do not know of the
rule change.

Subject: Re: Control Link/Repeater Linking
There is much confusion and disagreement between hams as to what is
legal in part 97. If you search the SERA band plan you will find
auxiliary stations but no control links on 2 meters but 440 MHz has
control links listed. Auxiliary station and a control link frequency are
two different things.

My reply to that was:

Your losing me.
According to Part 97:
“ §97.213 Telecommand of an amateur station. An amateur station on or
within 50 km of the Earth's surface may be under telecommand where:
(a) There is a radio or wireline control link between the control point
and the station sufficient for the control operator to perform his/her
duties. If radio, the control link must use an auxiliary station. A
control link using a fiber optic cable or another telecommunication
service is considered wireline.
(b) Provisions are incorporated to limit transmission by the station to
a period of no more than 3 minutes in the event of malfunction in the
control link.
(c) The station is protected against making, willfully or negligently,
unauthorized transmissions.
(d) A photocopy of the station license and a label with the name,
address, and telephone number of the station licensee and at least one
designated control operator is posted in a conspicuous place at the
station location. aAnd
“ §97.201 Auxiliary station. (a) Any amateur station licensed to a
holder of a Technician, Technician Plus, General, Advanced or Amateur
Extra Class operator license may be an auxiliary station. A holder of a
Technician, Technician Plus, General, Advanced or Amateur Extra Class
operator license may be the control operator of an auxiliary station,
subject to the privileges of the class of operator license held.
(b) An auxiliary station may transmit only on the 2 m and shorter
wavelength bands, except the 144.0-144.5 MHz, 145.8-146.0 MHz, 219-220
MHz, 222.00-222.15 MHz, 431-433 MHz, and 435-438 MHz segments.
(c) Where an auxiliary station causes harmful interference to another
auxiliary station, the licensees are equally and fully responsible for
resolving the interference unless one station's operation is recommended
by a frequency coordinator and the other station's is not. In that case,
the licensee of the non-coordinated auxiliary station has primary
responsibility to resolve the interference.
(d) An auxiliary station may be automatically controlled.
(e) An auxiliary station may transmit one-way communications.
According to this, a control link IS an auxiliary station and an
auxiliary station is allowed on two meters. I’m pretty sure that I’m
reading the FCC rules correctly… are you saying that SERA does not
endorse control links on 2 meters?
I’m trying to understand, but what you’re telling me appears contrary to
what I’m reading.
<End Snip>
Am I totally losing my mind here, guys? If a control link must be an
Auxiliary Station (97.213.a) and an Auxiliary Station may transmit on 2
meters (97.201.b), how can a control link frequency be different than an
Auxiliary Station?

Greetings all,
Please pardon my ignorance, but with the group of experts who hang out
on this reflector I’d prefer getting the straight-poop from those who
have ‘been-there/done- that’, rather than trying to find the correct
answer the old-fashioned way!
I’m considering adding a control link to our clubs 2-meter repeater.
Currently, we use the phone-line as control link, but it’d be nice to
have a second means of control.
The controller is a CAT-1000, so I think I can just use the port for the
2 nd radio (need to do some more reading in the manual to see what
functions are allowed with that setup). Am I barking up the right tree?
Any downside to this? Do I need to coordinate the link frequency
through our coordinating body (SERA)? Can I eventually use this link to
link two repeaters? Am I too stupid to attempt this?
Again, pardon me asking prior to doing the research myself, but this
place is a wealth of knowledge and with WAY too little time to do
everything I’d like to do I sure appreciate everybody’s assistance.
Mike
