Thanks for including it Gary. I enjoyed reading it and learnt a lot from it. The following paragraph about microwave ovens caught my attention: >The molecular vibration caused by MW is how and why a MW oven works - >exposure of the food to the microwaves causes water molecules to vibrate and >get hot. MW and RF penetrate and heat best when the size of the object is >close to the wavelength. For the 2450 MHz (2.45 billion Hz) used in >microwave ovens the wavelength is 5 inches, a good match for most of what we >cook. And I thought that this frequency was picked because it was close to a resonant frequencty of the O-H bond present in water, sugars and fats - common though often undesired components of what we eat.

NOTE: The Effective Sunspot Number for 08 JAN 94 was 60.0. The Full Kp Indices for 08 JAN 94 are: 1o 2o 3- 3- 3- 2+ 2- 1+ SYNOPSIS OF ACTIVITY -------------------- Solar activity was low. Only one C-class flare occurred: an optically uncorrelated C1 at 1254Z. Region 7648 (N07W11), the largest group on the disk, showed overall simplification and was quiet. Region 7650 (N05W01) displayed modest growth. Solar activity forecast: solar activity is expected to be low. STD: A long-duration class C8.2/SF flare was observed from Region 7646 (S08W82) at 09/2323Z. The flare was accompanied by a moderate Type II sweep that had an estimated shock velocity of approximately 600 km/second. The geomagnetic field has been at quiet levels for the past 24 hours. Geophysical activity forecast: the geomagnetic field is expected to be generally quiet to unsettled for the next two days. An increase to active is expected on day three due to a favorably positioned coronal hole.

Middle Latitudes Active 10/15/60 Minor Storm 05/05/10 Major-Severe Storm 01/01/01 B. High Latitudes Active 10/15/55 Minor Storm 05/05/15 Major-Severe Storm 01/01/05 HF propagation conditions were normal to above normal over most regions today, particularly over the middle, low, and equatorial regions. MUFs have remained enhanced about 10 to 20 percent above normal and the quiet levels of geomagnetic activity have contributed to very good propagation over the middle and lower latitude paths, with MUFs being enhanced in many cases by as much as approximately 25 to 30 percent. No significant changes are expected until 12 January when effects from a well-placed coronal hole should produce minor signal degradation over the high and polar latitude paths.

Departing Region 7646 (S09W93) produced a long duration C8/SF at 09/2323Z with a moderate intentisy Type II and minor centimeter bursts. Region 7650 (N05W13) grew slightly and now 7650 and 7648 (N06W24) appear as abutted bipoles. Solar activity forecast: solar activity should continue at a generally low level. An isolated M-class flare from Region 7646 or the 7648/7650 complex is possible. STD: Moderate Ca XV emissions were observed on the west limb today. The intensity of the emissions has decreased from strong levels which were observed yesterday. The geomagnetic field was quiet at all sites. Geophysical activity forecast: the geomagnetic field should be quiet until late on 11 Jan when a coronal hole related disturbance is expected to begin. Active to minor storm conditions are forecast for 12 Jan with unsettled to active levels forecast for 13 Jan.

Activity during the first part of the week was probably the work of a pirate. Usually the group that activates this station will announce when they will be on the air. SYGS! (Save Your Green Stamp) 9M2, WEST MALAYSIA. Just a reminder that Neville, G3NUG, will be active from three islands off the west coast of West Malaysia during January and February. His callsign will be 9M2/G3NUG and he prefers the frequencies 14260 and 18140 kHz (both +/- 5 kHz). Look for him on: Pangkor Is. (AS-072) from January 14-21, Langkawi Is. (AS-058) from January 22-28 and Penang Is. (AS-016) from January 29 to February 10. Neville mentions that there has been no activity from AS-072 and AS-058 for about three years. All direct QSL request will be cleared by the end February. QSL via CBA. BV9P, PRATAS ISLAND. A group consisting of BV5AF, BV2AP, BV4AS, BV4OB and OH2BH were active from here on January 5th, for about 4 hours. It was reported that lots of VK and JA stations were heard calling the BV9P station on 14255 and 14260 kHz. There were no reports from anyone stateside that could not hear BV9P. Martti, OH2BH/VR2BH, was heard saying that another DXpedition would take place in March. Other reports also indicate that the BV9P group made about 630 QSOs with JA, BV and VK stations, and one single KH6 contact before going QRT. EI4VRU CARDS. Barry, N2PNG, who has just returned from Ireland, states he made 1800 QSOs in the limited time he had to operate. There are two QSL routes available to use: N2PNG CBA or Barry Kennedy, POB 222, Austinburg, Ohio 44010. HK0, MALPELO & GORGOLA ISLANDS. Ermanno was very active from Malpelo this past week as I2RAO/HK0 (not IT2RAO/HK0 as reported last week). He has gone QRT as of January 8th, but will returning on the air from Gorgola Island (in the Valle/Cauca Division group) January 12-15. It is unsure what this island will count for, so WFWL. There are many who hope his Malpelo operation will count (KYFC!). HS, THAILAND. Fred, K3ZO, will be arriving in Thailand January 8th and returning on February 15th. During his time there, he will activate the club station HS0AC with his personal Thailand call, HS0ZAR. Fred plans to be very active on 40 meter CW, both morning and evening gray line paths. He states the bottom end of 40 meters is full of CB'ers from Indonesia on SSB, so look for him above 7015 kHz (sometimes even as high as 7030, but not down on the very low end of the band). In regards to 80 meters, it is not normally permitted for amateurs to operate in Thailand, but he has asked for special permission to use the band from 2200z, February 4th thru 1700z February 6th, CW only. If he gets this permission, ("Which is by no means assured," states Fred) look for him around 3513 KHz. There will be no skeds or nets! Just a reminder that Reiner, DL2VK, is now active as HS0/DL2VK until January 31st. He will be active on all modes (mostly on CW) including PACTOR. P5DTG INFORMATION. For the many stations that worked P5DTG back in November of 1992, here is some bad news. Responses are being received from Josef, OK1DTG, the QSL Manager and Operator stating that the P5DTG operation was an unlicensed operation. The information was printed on Josef's OK1DTG QSL card with the QSO information blank and lined-through and the operators call on it. PY0, ST. PETER & ST. PAUL ROCKS. According to the son of PS7KM the planned three week DXpedition by four Brasilian operators to St. Peter & St. Paul Rocks that was to start January 10th, will be delayed until January 20th and will only be for two weeks. There were no reasons given for the delay. The group plans to have two stations working 24 hours a day from 160 to 6 meters on CW/SSB/RTTY/Packet. QSL SSB/RTTY/6m contacts to PS7KM and all CW contacts to PT7WA. S2, BANGLADESH. K4MZU reports working Manju, S21AM, around 1240Z on 20 meters longpath. Manju is a Bangladesh national and is newly licensed. QSL to PO Box 4000, Dhaka 1000, Bangladesh. DXCC HAPPENINGS. Another "Application For New DXCC Country" status was sent to the DXAC. Actually this application was a request to reinstate Aldabra Atoll to the DXCC Countries List. The application was filed by Kurt Bindschedler, HB9MX/S79MX, who was active from Aldabra November 1st and 2nd in 1993. Kurt believes Aldabra qualifies under the DXCC Criteria rule, "Point 1: by virtue of Governmnet." Aldabra was deleted from the DXCC List, June 28, 1976. All contacts now made June 29, 1976 and after with Aldabra counts towards Seychelles (S7). Kurt states, "the Seychelles government is the administrative authority for all outlying islands with the exception of Aldabra. Aldabra is administered by non-governmental, non-profit scientific and conservation organization SIF (Seychelles Island Foundation). SIF consists of a board of trustees, the execxtive officer and several foreign well reputed personalities as members, with offices on Mahe and in London."

On Nov. 16, they were allocated spectrum in the 150- and 400MHz bands. [....] The NVNG service, based on technology pioneered by radio amateurs, will be used for brief data messages, monitoring and control of remote industrial, agricultural, and natural resource facilities, and consumer alarm, electronic mail, and vehicle location. Launches of the first NVNG satellites are expected later this year. (The above is quoted, typos are probably mine...)

The balloon, launched on January 7 at 1626z, burst about three hours later and landed in Utah's Uinta mountains, likely between 9500 and 10,000 feet elevation. A search party, on January 8, got within about two miles of the believed crash site, but were unable to continue due to steep terrain and deep powder snow. Whether recovery will be possible before spring remains uncertain. Three beacons on the payload are still transmitting and have enough battery power to continue for at least several days. Reception reports are solicited. Reports from Illinois and Ohio have indicated good signals. Of particular interest are reports of reception through the Russian RS satellites, because this will give an idea of how practical this method of relaying telemetry will be for a later, longer-lived flight. Reports should include the receiving site, date and time of reception (preferably in UTC), and the frames of copied data. The frequencies are as follows: Frequency Satellite Satellite Output Frequency ----------- --------- ---------------- 21.229 MHz RS-12 29.429 MHz 28.322 MHz (not on a satellite input) 145.871 MHz RS-10 29.371 MHz The 21- and 145-MHz transmitters are on for three minutes and off for nine. They send CW (not MCW) carrying telemetry information. The 28.322 MHz beacon simply keys on and off and does not attempt to send code. This beacon, alone, has solar power. The keying rate indicates whether it is operating on solar power or from batteries. Solar power is indicated by a rate near 40 pulses per minute; battery power by a rate near 20 pulses per minute. It is unknown whether recent snows may have covered the solar panel. This transmitter may die as batteries run down, and then come back to life next spring as snow melts and the solar panel is again exposed to sunlight.
