MARCO Grand Rounds for December 2, 2007

From Warren, KD4GUA

Last Sunday we had 40 check-ins....this Sunday we will discuss an 18 year old revelation--that of the discovery of the interaction of GRAPEFRUIT JUICE with medications. Only this time there is a new angle. It has been found that the price of expensive drugs, especially HIV drugs, can be cut in less than half by the possible addition of grapefruit standardized pills. For example (this is no joke)....Viagra 100 mg tablets cost $10 each. By taking 1/4 the tablet ($2.50) with a glass of grapefruit juice you can get the same effect. DON'T TRY THIS, it is given as an example of how the price of drugs can be reduced by simple means.

"Aether" is at the printers and should be available soon...pdf file pending.

MARCO Grand Rounds for November 25, 2007

From Warren, KD4GUA:

This Sunday we will discuss "TRANSCRANIAL MAGNETIC STIMULATION."

"THE SKULL IS A GOOD INSULATOR...CONSIDER HOW EASILY A MAGNET UNDER A WOODEN TABLETOP CAN MOVE A PIN ON THE SURFACE--magnetic fields pass almost unaffected through insulators including the skull." What happens when we pass currents into the brain? Tune in and......more Sunday, 10 a.m. Eastern 14.307. Should be fun.

Note: We lost a good ham Monday, Bill, W4TAD (Tender and Deliciouis, Tired and Disgusted) went West...he had a perfect 4 year attendance record on Grand Rounds. He will be missed--he is the doc who got me into Marco! Warren KD4gua.

Last week we studied "Deep Brain Stimulation" in the treatment of Parkinson's Disease among others.

This Sunday there is a contest and I will be enroute to Branson, MO for four days. I tried to contact Harry WB9EDP but couldn't get through via email. Perhaps Bruce could handle the net control if Harry is unavailable.

I expect to return to the shack on Thanksgiving Day and will discuss TMS Transcranial Magnetic Stimulation" the process of altering brain signals externally. TMS is painless and non-invasive and is currently being used in treating depression, epilepsy and stuttering. One researcher at Canada's Laurentian University is convinced that naturally occurring electromagnetic fluctuations could be responsible for paranormal experiences, like ghosts, UFOs and mystical apparitions.

Some have argued that religion itself could be electromagnetic in origin. Bone up on TMS for a week from Sunday.

Blog-meister's note: Given that we don't have a topic for discussion and are certain to be battling intense contest-related interference, I suggest that we take the week off and return to the airwaves on November 25.

MARCO Grand Rounds for November 11, 2007

From Warren, KD4GUA:

This Sunday we will delve more deeply into the treatment of Parkinson's Disease, namely, "Deep Brain Stimulation." This is now being used for depression, Tourette's syndrome, Obsessive Compulsives, Phantom Limb Syndrome and Cluster headaches. The Chinese are also using it to wipe out Schizophrenia.

Hogwash? Some of these treatments, including that for Parkinson's have been approved by the FDA (2002).

Geostationary Satellite News

From MARCO member JoAnne Maenpaa, K9JKM:

Hi Everyone,

I joined MARCO last spring after seeing your booth at Dayton.  I'm an RN in
a cardiac unit for my 'day job'.  Another one of my 'nite job' activities is
as the news editor for AMSAT ... The bunch that builds and launches
satellites.

At the AMSAT Syposium this past weekend we learned that AMSAT has been
offered an opportunity for a ride to geosychronous orbit.  I've attached the
AMSAT News Service Bulletin below.

It will still take a couple of years to get up there.  But think of the
emergency service capability a geosynchronous satellite can add to the
amateur service!

SB SAT @ AMSAT $ANS-301.01
The Weekend That Changed Amateur Radio

AMSAT News Service Bulletin 301.01
>From AMSAT HQ SILVER SPRING, MD.
October 28, 2007
To All RADIO AMATEURS
BID: $ANS-301.01

This past weekend, October 26-28 AMSAT-NA held a very successful Space
Symposium in Pittsburgh, Pennsylvania.

Rick Hambly, W2GPS, AMSAT President along with Bob McGwier, N4HY, AMSAT
Vice-President of Engineering were able to make public the results of
their recent work which will change the face of amateur radio going
forward.  AMSAT has been in consultation with Intelsat regarding an
application of an Intelsat platform carrying our amateur radio satelites
into geosynchronous orbit.

Engineering studies, funding studies, among other negotiations are
continuing at this point.  However Bob, N4HY made the following obser-
vation of the project AMSAT has termed Phase IV Lite, "There is enough
in place at this time that AMSAT needs to begin planning engineering
work and possible construction of a geosychronous payload so we are
ready if Intelsat says they have a ride for us."

The Phase IV Lite Geosynchronous Payload is planned to consist of
similar transponders already under development for the Phase 3 satel-
lites.  Accelerated development on the digital Advanced Communica-
tion Package is anticipated.  In addition to the communication pay-
load flown to space, AMSAT plans to develop an earth station attain-
able by the average ham so that users can immediately take advantage
of the audio, digital messaging, and video services.

The Advanced Communication Package would be a self-contained earth
station which could be sent with amateur radio communication teams
or delivered to disaster areas for 24/7/365 emergency communications.
These teams would be able to point a small dish at a predictable
spot in the sky and immediately begin delivering disaster commun-
ication support without depending on HF propagation.

A Phase IV payload could also be used to provide TDRSS-like relay
of ARISS communications.  The 10 minute school contact could now
be expanded to hours-long contact with the International Space
Station.  This opens possibilities for student involvement with
experiments aboard the space station.

The Intelsat geosynchronous platform would be able to provide the
AMSAT Phase IV Lite payload with approximately 400 watts of DC
power for 15 years.  The primary payload would also perform the
GTO boost phase as well as perform station keeping and antenna
pointing once it has arrived on station. Bob, N4HY summarized,
"The Intelsat team would be doing all the things nearly impossible
for amateurs and that enables AMSAT to do what we do best ... build
a communication system that changes amateur radio for the better!"

More details will be published in upcoming editions of the AMSAT
Journal.

We received an interesting reply from Jay Garlitz, AA4FL:

JoAnne, thanks for sharing the AMSAT information with the group.  I am
curious how many of us are AMSAT members?

One note about satellite ops is that we have a satellite station at W4DFU in
the Shands Hospital/Health Center complex at the University of Florida.
Satellite and echolink are the equipment used most often and attracts new
hams.  MARCO is an HF centric group and that is generational/traditional.
These other modes are getting new members in the door and we then excite
them about HF. (see www.gatorradio.org)

Please accept my comments as a possible way to attract younger health
professionals to the hobby, and to our ranks.

MARCO Grand Rounds for November 4, 2007

From Warren, KD4GUA:

This Sunday we will discuss "Parkinson Update."

There have been quite a few new drugs and procedures for this condition, mainly "deep brain stimulation." Back in 1943, a neurosurgeon removed a brain tumor in a Parkinson patient and damaged the globus pallidus and noted his tremor subsided. This, the idea of damaging the basal ganglia to improve Parkinson Disease evolved. Tune in, should be fun.
