According to 47CFR97, a trustee is the licensed person

Repeaters can be operated by any class license (valid
for the frequency, of course). While the person who's

trustee, there's no requirement for that title as

Greetings all,
Please pardon my ignorance, but with the group of experts who hang out on

'been-there/done-that', rather than trying to find the correct answer the
old-fashioned way!
I'm considering adding a control link to
Here in ARCC land (arcc-inc.org) we require re coordination whenever
the coordinated repeater's footprint changes.
A change in:
Location? Definitely!
EIRP? Yep!
HAAT? Sure thing.
License change? Trustee change? Call change? Notification
(preferably in advance) from a responsible source
Every repeater has a trustee just like every license has a trustee. It
may not be the same person, but often times it is. My local coordination
entity requires that *IF* the trustee of the coordination is a club, the
trustee is the trustee for the FCC license.
Now, can we get off the semantics
There is a good reason for having a club callsign on a repeater instead of an
individual. In my case, I have two coordinations that are in an area with no
more available. I changed my coordination over to a club many years back to
prevent the coordination becoming up for grabs in the case

On the IC91AD if one programs a memory for DV and it scans accross an
analog signal on that freq the rig will remain there for short period of
time, determine if not DV and resume scan. I have not tried setting up
an analog freq and seeing what it does in scan if DV is encountered.
Paul,
I would think it would more correct to say the call on a repeater or
other station is not necessarily the trustee. My call is on my repeater
and I am also the trustee.
