Now a days, this Gem Net daily conducted on 7075Khz at 22.00hrs IST (16.30 UTC) except Saturday. In Saturday Net will Start at 21.30hrs IST (16.00 UTC).
During Saturday in net frequency at 22.00hrsIST Medical Information relayed to all the Hams. Medical Information will be taken any kind of disease or symptom and explain how the disease will come, precautions, first aid and other information will be informed. This program recently started on 4th April, 99 by Sara, VU3RSB from Hyderabad.
When Net was started at that time Net control are VU2AID, VU2AB, VU2GJR, VU2SGR,VU2MIR, etc., Later January 1st 1998 net revived by VU3RSB. When VU3RSB controling at that time no alternate net control for the GEM Net. Unforunately VU3RSB few days net was not conducted due to various reasons like non availability of Equipment, QRL etc. Finally with the help of National Institute of Amateur Radio, VU2NRO restarted the Net on 3rd March 1999. At that time in Gem Net Frequency other net was progress and which was started recently. So Net frequency changed to 7075Khz from 4th March 1999. As a present Net control, I request everybody to help me as a alternate net control enable me to conduct the net without fail.
ORIGIN OF GENERAL EMERGENCY MEDICAL NET (G E M NET)
This very useful and life saving net started just like this. One day myself, Cpt.Dasan (VU2AID) since we had a common interest in flying he being a professional pilot and myself being a hobby flyer (private flying licence holder once) were having a chat on some mysterious midair aircraft explosion and its meteorological aspect of possibilities etc. At this juncture, I casually mentioned Capt.Dasan who was an ex-Air India flying Captain that when someone eats the fatty lunch provided on board including potatoes etc which are gassy and FARTS (Letting out gas the wrong way) and right at that time passenger of the next seat lights a cigarette. How about this gas let out causes explosion due to the next passenger lighting his cigarette.
Just then Dr.Samad another ham from Kerala broke in and promised to check the gas nature from human source at his biochemistry lab. Infact the very nextday he came up on the band and assured that this may not be the cause for any explosion since the gas 1. Wet and 2.contains mainly H2S which is not volatile. Then someone came on the band and asked some medical advice fromDr.Samad.
After a few days Govi (VU2SGR, Gaja VU2GJR, Dr.Velu VU2ENT, along with the earlier three for fun had this nightly net not named then conducted to pass medical traffic , medical advise etc. Just then VU2RDH OM.Radha who was then a new ham asked for a help to locate and help a poor girl from his village who had come to Madras for Knee cancer treatment. With great difficulty we managed to locate this poor girl in a slum quarters really struggling to get good treatment.
Next day, myself, Capt.Dasan, Govi, Gaja and Charu(VU2SCU) took this girl to nearby All India Cancer Institute where they mercilessly demanded Rs.60,000/-for amputation and chemotherapy and the chances of then surviving rate was only 3 out 10. The mother of the girl agreed and immediately we collected about Rs.6500/- what we could manage out of our pocket then and assured the hospital that they should go on with further treatment and we will undertake to pay the rest of the bill. We immediately returned to my morning QTH where I typed a letter in this regard and during this time we coined the name "GEM" acronym for General Emergency Medical and still this club is registered and I am the Tech.adviser and VU2AIG(Grace ) is the treasurer and we still have some money in the bank on this account. We used to get request from 4S7land and other part of the country for medical help, which was being extended actively.
During mid 90 I left for US and VU2SGR was also not keeping good health and since several request for medical help were also being communicated on CW not many who were taking part could manage. It must be stated that during this period Dr.Gaja and Surya one night along with other members of the GEM net rendered assistance to a child of a doctor from Kerala but unfortunately it was a cardiac operation and the child became a silent key. Our people contacted all the concerned in Kerala and finally Dr.Gaja managed to get a vehicle to take the dead child back to Kerala with all assistance enroute to minimize any trouble.
We also extended the GEM net operation on 14MHz with another team operatingSplit-band mode operation. When after my return the activity was not that terrific and Dr.Gaja was individually handling some medical traffic for 4S7 friends only both through 7MHz SSB and Packet mode.
GEM Net, General Emergency and Medical Net revived and reconstituted by Sarath has really helped so many people in getting the Medicine in emergency. A peep into his diary will certainly explain the people who were benefited and from where to where. The purpose is not to gain the popularity and name but only to serve the people with real interest. That is the reason why Sarath has not maintained any log for the assistance rendered to any body. The objective behind the GEM, the aim of GEM and the idea behind the GEM are entirely different from the usual log book nature. Purposefully, no log was maintained for GEM.
When net revived and started i.e., on March 4th 1999 got 38 check ins and later improved upto 48 check ins and least was 18 check ins . on 11/04/1999 check ins are 39 check ins. Shortly active chek ins list will be added to this page.
In GEM Net recently on April 3rd 1999 onwards started new activity . Every Saturday during net time medical topic either disease or symptom will be taken. Explain how the disease or symptom will arise, precautions, first aid etc. Information will be passed.

How Heat Affects the Body
Human bodies dissipate heat by varying the rate and depth of blood circulation, by losing water through the skin and sweat glands, and -- as the last extremity is reached -- by panting, when blood is heated above 98.6 degrees. The heart begins to pump more blood, blood vessels dilate to accommodate the increased flow, and the bundles of tiny capillaries threading through the upper layers of skin are put into operation. The body's blood is circulated closer to the skin's surface, and excess heat drains off into the cooler atmosphere. At the same time, water diffuses through the skin as perspiration. The skin handles about 90 percent of the body's heat dissipating function.
Sweating, by itself, does nothing to cool the body, unless the water is removed by evaporation -- and high relative humidity retards evaporation. The evaporation process itself works this way: the heat energy required to evaporate the sweat is extracted from the body, thereby cooling it. Under conditions of high temperature (above 90 degrees) and high relative humidity, the body is doing everything it can to maintain 98.6 degrees inside.
The heart is pumping a torrent of blood through dilated circulatory vessels; the sweat glands are pouring liquid -- including essential dissolved chemicals, like sodium and chloride -- onto the surface of the skin.
Sunstroke
Some persons may suffer a heat stroke as a result of prolonged sun exposure, involuntary or not, or exposure to very hot temperatures.
Overexposure to heat will result in the dysfunction of the body's heat regulation system. A heat stroke first produces profuse perspiration followed by fatigue, general exhaustion, inner cold sensation, vomiting and occasional fainting fits.
Sweating ceases suddenly, skin turns red, respiration changes, pulse rate decreases and becomes irregular. Increased metabolism, along with heart and electrolytic complications will induce a coma and death in some cases.
Treatment consists in fanning the body and covering it with wet blankets in order to try lowering its temperature.
The symptoms of sunstroke are headache, nausea, muscle pains, fever and vomiting. These are the body's reaction to overexposure to the sun or the increased stress of heat and activity. Consult a doctor if the symptoms or fever become severe.
To avoid sunstroke:
Cover your head well from your forehead to the nape of your neck with a broad brimmed hat when outside in the sun. Drink plenty of fluids and avoid intense activity in the heat of the day. Wear sunglasses if exposed to glare.
Anyone with a history of cardiovascular disease should take extra precautions.
Preventing Heat-Related Illness
Elderly persons, small children, chronic invalids, those on certain medications or drugs (especially tranquilizers and anticholinergics), and persons with weight and alcohol problems are particularly susceptible to heat reactions, especially during heat waves in areas where moderate climate usually prevails.
Too Much Heat
Heat disorders generally have to do with a reduction or collapse of the body's ability to shed heat by circulatory changes and sweating, or a chemical (salt) imbalance caused by too much sweating. When heat gain exceeds the level the body can remove, or when the body cannot compensate for fluids and salt lost through perspiration, the temperature of the body's inner core begins to rise and heat-related illness may develop.
Ranging in severity, heat disorders share one common feature:
the individual has overexposed or overexercised for his/her age and physical condition in the existing thermal environment. Sunburn, with its ultraviolet radiation burns, can significantly retard the skin's ability to shed excess heat.
Studies indicate that, other things being equal, the severity of heat disorders tend to increase with age -- heat cramps in a 17-year-old may be heat exhaustion in someone 40, and heat stroke in a person over 60.
Acclimatization has to do with adjusting sweat-salt concentration, among other things. The idea is to lose enough water to regulate body temperature, with the least possible chemical disturbance.
Heat Wave Safety Tips
Slow down. Strenuous activities should be reduced, eliminated, or rescheduled to the coolest time of the day. Individuals at risk
should stay in the coolest available place, not necessarily indoors. Dress for summer. Lightweight, light-colored clothing reflects heat and sunlight, and helps your body maintain normal temperatures.
Put less fuel on your inner fires. Foods (like proteins) that increase metabolic heat production also increase water loss.
Drink plenty of water or other nonalcoholic fluids. Your body needs water to keep cool. Drink plenty of fluids even if you don't feel thirsty. Persons who (1) have epilepsy or heart, kidney, or liver disease, (2) are on fluid restrictive diets, or (3) have a problem with fluid retention should consult a physician before increasing their consumption of fluids.
Do not drink alcoholic beverages.
Do not take salt tablets unless specified by a physician.
Persons on salt restrictive diets should consult a physician before increasing their salt intake.
Spend more time in air-conditioned places. Air conditioning in homes and other buildings markedly reduces danger from the heat. If you cannot afford an air conditioner, spending some time each day (during hot weather) in an air conditioned environment affords some protection.
Don't get too much sun. Sunburn makes the job of heat dissipation that much more difficult.
