Hi
Vandaag kreeg een nieuwe vergunning voor de 2,3 en 3,4 GHz huidige 1 / 7 - 31 / 12 Zeer verrassend. Ik dacht dat het was helemaal zo ver als 3.4 GHz.......... uitgeput.

Evenementen / Heelweg / See you next year in Heelweg

Good morning, thank you very much for the great meeting in Heelweg some weeks ago. I am very sorry, but we have been too late with the 2nd Generation of the SHF-IF-Transceiver, otherwise I would have took it to Heelweg to discuss some technical details. If you like - there is an english video at youtube, just search for DF-202 and / or DK2FD. So I just write this mail to you because we (some students and me) will be at the fleamarket in Hertogenbosch in about 10 days at the booth of HTB (they are dealing with used measurement equipment) and put one or two DF-202 on the desk to play with it and maybe get some response for modifications. As this is an SDR-Project (still under development, we are working on the 3rd generation now) and there is plenty of memory left in the processor its possible to get more features inside. See you next year in Heelweg - and maybe before at some other meetings, maybe in Hertogenbosch. If you like you can share this info with other SHF-Hams, we are interested to discuss technical details. 73 Dirk, DK2FD dirk.fischer@fh-muenster.de

Microwaves / 47 Ghz / New National VK Records - 47 GHz.
|
Gepost op: Januari 15, 2017, 11:55:44
|
Gidday All, this to advise the 47 GHz VK National Records on both SSB and Digital Modes were extended by VK3 Operators on Wednesday, January 11.
The new Distance Records for both these Modes on 47 GHz are now out to 177.9 km.
The following is a brief summary of our activities and the equipment used.
Our initial activities started on Tuesday, Jan 10th with the team of David - VK3HZ and Peter - VK3APW setting up at the Mt Dandenong Observatory, East of Melbourne.
Alan - VK3XPD drove to a spot near Mt Cottrell, west of Melbourne. This site delivered a Line Of Sight (LOS) path of 64.2 km. Crushingly strong signals were experienced on both 47 GHz and 78 GHz over this somewhat modest path.
Alan subsequently drove (and operated) further west at Myrniong (90.2 km) and finally Mt Buninyong (127.1 km) where he was visited by Ian - VK3AXH as an interested observer.
These progressively longer QSO's were a "shakedown run" for the main event planned for the next day.
To avoid excessive driving on his part, Alan then drove further west and stayed overnight in a Motel in Stawell. Next day - Wednesday, it was only a relatively short drive to the Summit of Mt William, south of Halls Gap. David and Peter took a little longer driving from Melbourne to Colac.
At around 1030 Hrs, Alan - VK3XPD arrived at the 1158 metre summit of Mt William in western Victoria. Visibility was only a few metres due heavy misty clouds and there was (initially) no Cell coverage.
The team of David - VK3HZ and Peter - VK3APW initially drove to a location south of Colac from which both the SSB and DIGI Records were extended to 149.6 km.
Later the same day, David and Peter relocated to Mt Sabine in the Otways, east of Beech Forest from where these new National Distance Records were further extended to 177.9 km.
Equipment: VK3XPD/3 - Homebrew OCXO-Locked Transverter, 20mW output, 300mm dish, FT-817 IF. VK3APW/3 and VK3HZ/3: - Kuhne OCXO-Locked Transverter, 80mW output, 300mm dish, FT-817 IF.
QSO's on 78 GHz were also attempted and although we did detect very weak "Ident" signals albeit briefly, we were ultimately unsuccessful due to poor propagation (high path losses) on this band.
At the end of this very long day, we all headed home - sunburnt and rather tired but pleased our significant efforts had been rewarded !
Cheers,
Alan - VK3XPD For and on behalf of David - VK3HZ and Peter - VK3APW.
