G8UGD


Welcome




Station details.


Operator name is Adrian

Locator is IO83SR near the town of Blackburn in the North West of England. 
Approx 31 Km North West of Manchester.  It is typically raining, dull, cold and miserable. :)

I am getting back into the hobby now work is behind me!   But as I enjoy engineering, mostly metal engineering as well as radio, you may find many of my home made items have a large metal content to them.

Active on QO-100 mainly on DATV and very occasionally on the narrow band segment typically with SSB.

Not interested in just location and signal report contacts, it's not what the hobby is to me.

QO-100 SSB.

TX line up is an old Standard C58, 2 metre multimode driving a BU500 up-converter.  2.4GHz block filter and 7 metres RG213 to a dual feed POTY on a 1 metre offset dish.
RX line up, same dish to a SDR receiver and SDR console, simple.  Plans are being built for a dedicated RX system with no computer dependence but will be some in the future.









QO-100 DATV

Have built a simple DATV system for the Wide Band section of the satellite.  I initially used a Hackrf One to generate the DATV signal and then various amplifiers to gain enough wideband power to achieve some modest video signal on the satellite.  Have now got a Pluto SDR and using the modified firmware from F5OEO and OBS studio on the computer to take care of the video side.



PA line up is per the following diagram, with a couple of home made interdigital filters at 2.4GHz to provide my best effort to stop spurii from being generated out of band.







The PA unit was assembled from boards off Ebay with an aluminium plate machined to accept the PA devices and circulator, the aluminium is then bolted to extruded aluminium heat-sinks.  The PA then fitted with a cowl and fan to assist with air flow.  Then all mounted onto a steel plate to keep it as one project, a couple of IMO timers and relays switch on the power when the psu's have settled.  No monitoring equipment is yet fitted.  All this is now in a home made steel enclosure kept outside close to the dish to keep the feeder length to just a few metres.

For receiving WB DATV.  I have two MiniTiouner_Express receivers, F6DZP's and Longmynd software to decode the downlinks, again I have made a 744MHz Interdigital filter to reduce input noise to the Tuners from the wideband output of the LNB.  You get the idea about metal work being part of my projects now!


HF.

Trying to be more active on HF.  If the weather is dry, sunny and warm, could be found mobile in the car pictured at the top of the page.  I strap in a FT-857 and use AM-Pro style whip antennas.

At home I will be using using a 39 year old Yaesu FT-902DM from home with a simple 20m wire dipole at around 5 metres high, if we make contact it will generally be your antenna system that makes it possible, restrictions at this end can prevent obvious antennas.



I do not QSL.   I run a simple spreadsheet log on my own PC as I have not migrated to any internet based system logging system.

Hope to see or hear you on the bands, lets have a natter.  

Will put more on here when time permits and I have more to add!
