Today at around 4.pm I connected my wsprlite antenna analysis system to the club 40m Dipole after completing the 40m low pass filter. It is now transmitting at 200mw and here is the first image from the spots map. The test will continue for 3 days, i will publish data as the test progresses.
Last week was the second week with Paul m0zmb showing some of his experiments using the Arduino open source electronics platform. We looked at a full colour LCD display from Tony G0WMB and my (John m0hfh) experiments to link the Arduino and a AD9850 dds module to give a variable sine wave output with a variable frequency from a few kilohertz to 30mhz; a very useful VFO. We stayed later than we should to test the output using the club radio on 3.5mhz and 7.2mhz and the circuit achieved our first goal, and a signal was detected at approximatly 4m distance using very crude wire antennas.
A short days operating from a low G5rv and 100watts using mainly club equipment yielded 8 countries see qrz.com for full details. Thanks to all club members who turned up, and participated in a fun day operating from the Berkeley Vale Railway offices supporting railways on the air.
Everything is ready for Saturday at the Vale of Berkeley Railway for Railways On The Air. At the moment we have only 2 people attending and it would be nice if we could get a couple more even if only for an hour or so.
If you are interested please see Rex or John.
Our callsign will be GB4VBR.
Rex (G4RAE), John (M0HFH) and myself (M6EAT) made an interesting visit to the Vale of Berkeley Railway on Saturday in preparation for ROTA on Saturday 23rd September.
We are undertaking a short visit again this Saturday for some antenna prep and then we will be ready for the day.
We could still do with some more radio operators for the day as I am actually away on holiday. The railway are very interested in this and have given the club the use of the boardroom for the day so everything will be nice and warm and dry.
If anyone can make a few hours then please let one of use know.
