Good morning. It's Sunday the 6th of June and here is the GB2RS news broadcast, prepared by the Radio Society of Great Britain. And we start with a special 'good morning' to all taking part in the RSGB National Field Day Contest. First the headlines:- Look out for GB5SAW and GB2SEG this week; there's another Microwave Round Table this month; and bookings for the AMSAT-UK Colloquium are due in by the end of the month. The callsign GB5SAW will be aired by the South-East Essex Sixth Form College from tomorrow, Monday the 7th until Friday the 11th, under the guidance of George, G1VCY. The idea is to introduce the students to the fascination of amateur radio. Operation will be on 2 metre and 70 centimetre, SSB, FM and Packet between 10am and 4pm. If you hear them, why not call in? If you are unable to call during the operating periods, then send a packet message to GB5SAW @ GB7DUG. Last years event was an unqualified success and an even better response is hoped for this year. News now of an expedition by the Scottish Expedition Group to Buchan Ness, the most easterly point on the Scottish mainland. The callsign GB2SEG will be aired from next Friday the 11th through to Sunday the 13th. The WAB square is NK14 and the locator is IO97CL. For further information contact George, GM2TW on 0324 715624. All listeners to this broadcast, whether RSGB members or not, are invited to the RSGB Headquarters Open Day on Saturday the 19th of June. This is a chance to tour the Society's administrative Headquarters, visit the GB3RS shack and see the QSL Bureau, Library and Museum. Doors are open between 10.30 am and 4.30 pm. Staff and volunteers will be on hand to answer queries, and the book shop will be open all day. A map of how to get there can be found in the June edition of Radio Communication, or call Belinda Gannon on 0707 659015 for details. There will be another RSGB Microwave Round Table meeting on Sunday the 20th of June.

The attractions include: Technical talks, power and noise figure measurements, travelling wave tube demonstration and the usual round table discussions. There will also be a bring and buy stand. Hot drinks and snacks will be available. For further details telephone Mike, G3LYP on 0494 881298. The Annual AMSAT-UK Colloquium takes place from the 29th of July to the 2nd of August. Full details of this major event for those interested in satellites can be obtained by writing to AMSAT-UK, 94 Herongate Road, Wanstead Park, London E12 5EQ. Completed booking forms for those attending and needing accommodation should be returned to AMSAT-UK, by the 1st of July. Now some items of HF DX news from the weekly RSGB DX News Sheet which is edited by Brendan McCartney, G4DYO. From the Bahamas, N4JQQ will sign C6AFP from the Island of Great Abaco, from tomorrow, Monday the 7th for one week. Main activity will be on 6 metres, but some WARC band and CW operation is also likely. From Svalbard, LA6MY is signing JW6MY from now until September, using CW only. From Ile Verte, a French group will use the callsign TM5IV from Friday the 11th, until Monday the 14th of June. Rally news now and we know of one Rally for today, Sunday, the 6th of June: The 25th Spalding Mobile Rally is being held at the Springfield Gardens, Spalding. Doors open at 10.00am.

And we have news of three other events later this summer: The organisers of the Longleat Amateur Radio Rally are apparently suffering from an incorrect rumour concerning entrance prices. It is quite untrue that it will cost over ten pounds a head, the entrance will be a modest increase on last year at 2.50 for adults, 2.00 for pensioners and 50 pence for children. The Scarborough Amateur Radio Society regrets that due to circumstances beyond its control, the Radio and Electronics and Computer Rally planned for the 25th of July has had to be cancelled. However, the club is pleased to announce that next year's Rally will be held on the 29th of August 1994, Bank Holiday Monday, at the Spa on Scarborough Sea front. For further information contact Ross, G4ZNZ on 0723 514767. A new event is the East Yorkshire Radio Rally which will be held at the Beverley Racecourse on Sunday the 25th of July. There will be trade stands, special interest groups, plus a bring and buy stall. Traders or others interested should contact Peter, G4EJP on 0964 550397 evening or 0964 550921 during working hours. HF contest news now: The RSGB's HF National Field Day is taking place this weekend, finishing today, the 6th at 1500GMT. An article celebrating 60 years of NFD can be found in June's RadCom. The All Asian CW Contest runs from 0000 on Saturday the 19th to 2400 on Sunday the 20th. All bands from 160 to 10 Metres will be used, but excluding the WARC bands.

Please note, this event does not take place on the 7th as printed in February's RadCom. Details for all three are to be found in February RadCom on page 66. And now the solar factual data The period 24th to 30th May has seen a reasonable increase in solar activity, with some quiet geomagnetic levels giving improved HF band conditions. Sporadic E has been reported on both 10 and 6 metres. Three small M type flares were reported, the largest being an M1.4/SF on the 28th. Sunspot counts climbed from 34 on the 24th up to 130 by the 29th giving a mean of 95 for the period. Solar flux levels have also increased reaching 140 units on the 30th, with the period averaging 117 units. The geomagnetic Ap indices were very quiet at first, being down to only 1 on the 25th, but rose to the very unsettled level of 21 units by the 27th, together with a considerable decline in HF band conditions. The period averaged 9.2 units. The state has been 'nil nothing to report' throughout the period. The data on radio quality indices are not all to hand due to the holiday. For the period 24th to 27th May levels increased well above normal up to very good, with the Tokyo and Fort Collins Boulder circuits being up to excellent. With the increase of geomagnetic levels on the 27th, the radio quality indices fell to well below normal. The daily average aa indices, as supplied by the British Geological Survey for the period 18th to 24th May, were down to quiet levels of only 11.4 nanoTeslas, K2, with the 24th being very quiet at only 5.8 nanoTeslas, K1. The X-ray flux has risen considerably reaching B4.9 on the 27th and averaging B3.7 for the period. Now the ionospheric data for Central France: This week, due to the holiday, not all the data is to hand. The F2 daytime critical frequencies at Poitiers as reported by Meudon for the 24th to the 27th of May rose to quite high levels, reaching 9.4MHz on the 26th and averaging 8.7MHz for the period. The darkness hour lows have not changed much and averaged 4.9MHz. Now the ionospheric data for the north: The F2 daytime critical frequencies at Ekaterinberg for the 23rd to 27th May averaged 7.6MHz and the lows 5.8MHz. And now the solar forecast: This week, one of the quieter parts of the sun will be looking our way. Solar flux levels are expected to be about the 110s. Based on the radio quality indices, the HF bands should be around normal but the passage of an old but rather large coronal hole may give some magnetic disturbance later in the week. The Lyrids meteor shower is expected from the 4th to the 12th June. And finally, Nikola Tesla's dream has come true. A series of far reaching experiments in the Space Power Systems project has now shown that very large amounts of usable power can be transmitted at microwaves, using Wireless Power Transmission Technology. In one test 30 kilowatts was passed using a frequency of 2.45GHz which was converted to DC with an efficiency of 82%. Recently an aircraft used for communication purposes was controlled, and kept at the high altitude of 70,000 feet indefinitely, powered by microwaves. Tesla was rather ahead of his time in 1912 when he tried to do it on Long Island. And that is the end of the propagation information. Finally in the main news, SSL has informed the Society that as of last Wednesday morning, the latest callsigns issued were in the G0 Tango Tango and G7 Oscar Whiskey series, and Novice calls in the 2 0 Alpha Foxtrot and 2 1 Bravo X-ray series. You're listening to GB2RS, the news broadcasting service of the Radio Society of Great Britain, transmitting in the 80, 40, 6 and 2 metre bands.
