Art,
Very helpful indeed. Thanks for taking the time to clarify for me at
least - a subject that has at times been both confusing and contentious.

Hi, Bill,
Go to http://www.fcc.gov and search for “experimental.” Strongly
suggest reading Part 5 of the FCC rules first. (See:
http://www.gpo.gov/fdsys/browse/collectionCfr.action?collectionCode=CFR&searchPath=Title+5&oldPath=Title+5&isCollapsed=false&selectedYearFrom=2013&ycord=161.
You may have to wait for Title 47 (Telecommunications) to be added to
the 2013 edition, then go to Part 5.) Make sure you have the version
revised this year.
Some thoughts for you.
To the good: Experimental stations can be assigned to any frequency.
Experimental stations may be licensed for all the purposes listed in
Part 5 of the FCC Rules and Regulations. Commercial ideas can be
tried out. Operators may be paid. Encryption may be used.
Applications can be made online. The cost is somewhere around $100.
To the bad: Operation is secondary to EVERYTHING. In case of causing
harmful interference, the experimental station is required to cure the
problem, which usually means being ordered to shut down immediately
with no recourse. In case of suffering harmful interference, it must
be tolerated. (Not a good options for significant investments in time
and money.) Communication is normally permitted only with stations
listed on the license. Communication with regularly licensed stations
(including amateur) is forbidden. International communication is
normally forbidden, unless administrations made arrangements in
advance. International coordination is usually required.
One more thing on sharing bands allocated to the amateur-satellite
service. FCC now requires IARU coordination, though they didn’t give
IARU notice. (This story requires several 807’s.) To help out folks
who had already built projects thinking (erroneously) that they could
fly as amateur, IARU worked out an arrangement to provide coordination
service on a TEMPORARY basis. Coordination requested in the 144-146
MHz will no longer be provided for experimental stations after mid
2014. See 2013 AMSAT Technical Symposium Proceedings.
IMHO, appropriate radiocommunication services and frequency
allocations are already available, can provide international status,
and should be applied for, rather than amateur-satellite service
frequencies. Fees will be required, but FCC might waive their fees
with a justified request. ITU fees are normally required, except for
amateur stations.
I hope this helps.

Art,
Aaah! I wasn't aware of that. Thanks for clearing it for me anyway.
Can you point me to the FCC web link where I can understand (apply)
for an experimental license for a Cubesat in the Amateur bands.

Hi, Bill,
By special arrangement earlier this year, IARU agreed to provide
coordination service for experimental stations on an temporary
basis. Many of the experimental station operators are also licensed
amateurs, however that has no bearing on experimental station operation.
More on this in the 2013 AMSAT Technical Symposium Proceedings. See
the article by Hans, ZS6AKV.

Hi Art,
Now I'm a little confused by your comment that most Cubesats are
licensed as experimental. On yesterdays Minotaur launch, 17
Cubesats are operated by Amateurs and were coordinated through the
IARU.

One thing we learned in bureaucrat school is that jumping to
conclusions is not a healthy exercise. :-)
FCC licensed most of the new cubes as experimental stations and
not as amateur stations. Experimental stations may be assigned to
any frequency, provided they do not cause harmful interference to
stations operating in accordance with the ITU radio regulations.
See RR Article 27 and 47 CFR Part 5.
These experimental stations are not operating in the
amateur-satellite service, only sharing the bands on a secondary
basis. They are permitted to communicate only with stations
listed on their license, so it would be inappropriate for them to
seek help from amateurs, though amateurs may certainly listen.
Note that experimental stations may encrypt their transmissions.
Some of the satellites, such as TJ3SAT, and some others, are
amateur stations! Sure would be good for them to make a noise
here on BB!! (HINT!)
I hope this helps.
