Does anyone know where class to prepare to take exam for your license is offered and info?  My 23 year old son is asking to get his license and going to a class would be the best I think.

Thanks

Amateur Radio Assistance Requested: ISS Plasma Thrust Shadow Experiment

The Central Research Institute of Machine Building (TSNIIMASH) in
Russia is conducting a series of space plasma experiments in order
to evaluate the shape of previously observed "dead" zone, or shadow-
ing due to the firing of an onboard arcjet plasma source.

Radio Amateurs are invited to participate in the Space plasma exper-
iment "Shadow" onboard International Space Station (ISS). Integration
of Electric Thrust onboard a spacecraft poses a certain set of prob-
lems including electromagnetic compatibility of ET. One matter of
interest is that highly ionized exhaust plumes of ET may scatter RF-
signals producing large "dead" zone for communications.

This plasma screening effect should be thoroughly studied before
electric thrusters become standard onboard equipment. The investiga-
tion will help designers of future electrically propelled spacecraft
to minimize the hazard of communication disruption by ET plasma
plumes.

The Central Research Institute has proposed an experiment using the
worldwide distribution of radio amateurs to receive the VHF packet
downlink (145.825 MHz) from a new plasma space experiment on the
International Space Station.

The amateur packet radio technology in the SpEx "Shadow" as proposed
by astronaut Alexander Kalery, will use the AX25 packets transmitted
by "Master Stations" and reported by receiving amateur radio ground
stations to track the effect of the plasma shadow.

The SpEx experiment will be enabled on the following schedule:

   SpEX Time On          SpEX Time Off
--------------------  --------------------
November 25 1650 UTC  November 28 0825 UTC
December  2 1650 UTC  December  5 0825 UTC

The master beacon stations for Europe, Asia, North America, and
Australia can be found at:
http://tinyurl.com/84nvl72 (knts.tsniimash.ru)

The main web page for the SpEx project can be found at:
http://knts.tsniimash.ru/Shadow/en/Overview.aspx
This page contains a detailed description of the experiment
and instructions for submitting your signal reports.

An example of the SpEx packets received by Mike Rupprecht, DK3WN
can be seen at: http://www.dk3wn.info/p/?p=23866

[ANS thanks TSNIIMASH for the above information]
