There was no planned “event” for this evening’s meeting, but we ended up with eight members and one non member visiting.
Ian, G7DWY brought along a hot air soldering station and decided to modify the club HF radio, a Kenwood TS570D so it covered the whole of 40m and 60m – something that we have been discussing for a while now. The process was simple enough – it took more time to strip the radio than it did to remove the resistor! The picture is of the radio after the resistor had been removed.
David, G3PTU brought along an SWR / Power meter which he bought from a rally for next to nothing as ‘none working’ it turned out that the meter movement was faulty, but soon replaced and life was once more breathed into it!
Trevor, G6XTZ brought along his new Motorola DMR handheld for people to play with and Tony, M5AIB brough his laptop and a couple of radios to program, but we ran out of time, so this may be carried over to the next meeting.
At the next meeting, if things go according to plan, Stuart, G0TAL will be bringing his FT847 to receive the same treatment as the clubs rig did this week and hopefully Tony will be bringing his programming equipment….. If you would like to come along to a meeting, drop a line to the secretary on just turn up.
Thursday 13th January saw the AGM of the Spen Valley Amateur Radio Society, and it was nice to see our full membership turn out on a cold, miserable evening. Not only that, but we were joined by a number of prospective new members.
There were a number of topics discussed after the end of proceedings including prospective talks for the coming year.
As always, some interesting things were passed between members including this tuneable filter that Dave, G4IDR is going to be using to try and reduce the interference and breakthrough he experiences on 2m when operating on EME.
OFCOM have announced a consulatation document regarding interference to readio users, their summary of which is:
“This document sets out Ofcom’s consultation on draft regulations for new wireless telegraphy legislation, intended to keep pace with technological advances to control interference.
Electrical and electronic apparatus are capable of emitting electromagnetic energy. In most cases, this is minimal and has no noticeable negative effects. However, in some cases the level of energy emitted from apparatus can cause interference to wireless communications.
Ofcom has powers to take enforcement action in instances where some types of electrical or electronic apparatus causes undue interference to wireless communications.
The proposed regulations are intended to be more resilient to technical developments.
The deadline for responses to this consultation is 16 February 2015.”
All radio amateurs are urged to read and respond to the consultation document before the deadline
We are currently organising the 2014/15 talks program. Generally, we break from having regular talks over the summer months when members are on holiday, so please check back here regularly for the new calendar.
But why not join us on the first and third Thursdays of the month for a noggin and natter night? There is usually all sorts being discussed from Microwave EME through contesting and DX on HF and VHF, Aerials and general electronics. There’s even talk about none radio related things!
This evenings meeting was just pencilled in as a ‘noggin and natter night, but we started with a bit more of a radio theme…..
Stuart, G0TAL has decided to get rid of some of his old radio equipment that is sat gathering dust in the attic, but before being listed on eBay, it needed testing to ensure it worked ok….
To this end Ian, G7DWY brought his Bird Thruline power meter and Doug, G4DZU provided an element to cover the HF bands.
The radio was then tested on transmit into a 50ohm dummy load, and the results were pretty good with the radio delivering its full rated output on the HF bands, but being a little down on VHF – it probably needs a little tuning.
We then connected it to the club aerial and verified reception on the HF bands.
The meeting continued, debating many diverse subjects, not all radio related, but all of interest.
As the meeting was finishing, I turned up the volume control on the club HF rig and had a tune around 17m (18Mhz). One call got a response from Tony VE3AXW in Brantford, near Toronto in Canada. Not bad for a non resonant dipole and 100w!
This evenings meeting has been a talk by Doug, G4DZU about time and frequency standards.
The talk focused on Doug’s quest for a reliable frequency standard, and how this had progressed from his early forays on 2m in the early 1970’s, and the acquisition of different types and accuracies of standards through his amateur radio life, culminating in the current standard locked to an accuracy of 1Hz in 10Ghz – useful for 23cms EME!
Doug then went on to cover how to lock modern radio equipment to a GPS based frequency standard and the importance of time synchronisation in modern digital modes – very enlightening.
Please feel free to come along to any of our organised talks, and many thanks to Doug for this evenings informative and interactive presentation.
