Nu hnder det lite igen!

AO40 gr otroligt bra med massa DX.

UO22 r igng

UO14 krnglar lite fortfarande

SO50 kar i popularitet tack vare att UO14 brjar krngla.

FO29 gr i digitalkermode tom 26/8 (man kan hra en inspelad rst p 435,910 FM)

VU sat kommer att skjutas upp i Oktober och vi fr ter igen en mode B satellit (435 upp 145 ned)

Vi vntar p att ISS ska brja snda SSTV bilder frn rymdstationen under slutet ret.

Med tanke p kommande Mars sond som Amsat DL hller p att frdigstlla s kan det hr vara av intresse.

During the period August 26-29 2003, NASA s Jet Propulsion Laboratory (JPL)in cooperation with the Stanford Research Institute (SRI) will be conducting a test of the Mars Relay transmitter aboard the Mars Global Surveyor (MGS)
spacecraft currently in orbit around Mars.

The test involves the spacecraft transmitting a 1 watt 437.1 MHz CW carrier for reception by the 46 meter dish at SRI.

Amateurs with 70cm EME class stations using DSP techniques may be able to detect this signal also. Andrew Bachler, N9AB, was able to detect a similar transmitter aboard Mars Odyssey while it was on its way to Mars in June of 2001.

This test will be somewhat more challenging as MGS
will be 3 times further away.

Dr. John Callas of JPL explains some of the difficulties involved: MGS will be entering and exiting occultati(blockage by Mars with respect to Earth)with each 118-minute orbit.

Furthermore, its UHF antenna (with about 0 dBi of gain, EIRP~30 dBm) will only be viewable from Earth for a few minutes (5 to 15 minutes) just before ingress and just after egress as it orbits.

SO50 har nu ven hrts p handapparat och gummipinne!

Avstndet till satelliten var vid tillfllet 1000km, och det betyder ju att man br kunna kra den med en enkel handhllen yagi och duobands handapparat.

Trafiken r betydligt lugnare n p den andra FM satelliten UO14 s det blir lite mer som ett vanligt lugnt QSO.

SM2BYA har lyckats f mjlighet att kra EME frn en jtteparabol i hst och det betyder att mnga satellitoperatrer har chansen att f ett QSO via mnen.

Det hr r en chans som knappast kommer igen.

Good news – the JW/SM2BYA 432 MHz EME operation is going to go ahead:

About a month ago we filed a scheduling request for the EISCAT Svalbard Radar 32-meter antenna for the weekend October 18-19, 2003, ie the first ARRL EME contest weekend.

It now appears there is about a 95 % likelihood for us to get the full contiguous 48-hour time slot from Oct. 18 00 UT to Oct. 19 24 UT ! This is much better than we ever dared hope for…

This operation will be predominantly CW and some SSB. Sorry, no JT44 and no skeds. Since Oct. 18/19 is one of the busiest contest weekends of the year,we have decided to pick a transmitting frequency and a listening band high
up in the CW segment, to minimise the risk of mutual interference between our operation and the regular contest traffic. The plan is for JW/SM2BYA to use 432.073 MHz for transmitting and .075 – .080 for receiving.

No SSB frequencies have been selected yet. To comply with the Region I band-plan, any SSB operation should be above 432.150. We are aware of the problems that may result because of the non-alignment of the band-plans in Regions II and III and are still thinking about how to handle the issue.

Due to the high latitude (78 N) the moon will be continuously above the horizon for the whole 48-hour contest period, so everybody should have a fair chance at
a contact.

The ESR antenna has about 41 dBi gain at 432, so two long yagis and 50 watts should be enough for a CW QSO with JW/SM2BYA. Please spread the word to terrestrial 432 operators !

UO14 har rkat i lite batteriproblem och var tyst under grdagen,Den har dock rapporterats idag igen s vi behver nog inte oroa oss allt fr mycket.

Dock r det lite illavarslande fr den r den mest ltthrda satellit vi har, (435070 FM.)
