The technology to support remote operation of amateur stations is developing and many possible solutions are around.
John G4SWX, who has run a remote home station for the last six years will review the technology options in the light of the amateur licence conditions.
John will then show some relatively simple options to add remote mains switching and metering to what would otherwise be ‘always on’ and ‘lacking in control’ systems. John will also explore why remote multi-user club stations have not yet appeared.
To accompany the talk John will have a selection of remote station equipment and 3G network permitting he will run demonstrations using his LF/HF/VHF station in the wilds of Suffolk.

OFCOM announce “Interference” consultation

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

Sporadic “E” 2012 up and running!

At last! (they all cry) the sporadic “E” season appears to have started in earnest, with Es events happening on 50Mhz most days this week.

Openings have been getting up to these latitudes, with G7DWY working into Spain (EA) and Italy (I) during the last couple of days.

More southerly latitudes have benefited from multi-hop Es, or Es / TEP to work into South America and Africa.

If you want to know what is happening, there is no substitute for sitting at a radio and tuning up and down the band, but good information can be gleaned from DX clusters, and VHF chats such as ON4KST.

Going a stage further, though, Gabriel EA6VQ has created the “DXSherlock” website which shows a graphical representation of ionosonde data showing the MUF and Es clouds, also the site lists activity by band – well worth a look if you are a HF or VHF operator.

Working Es is simple – you don’t need big antennae or high power (though they can both help!) In 2011 I had a 10 minute conversation with a German station who was absolutely end stop with me, and only running 10w!

Have a listen out – you never know what you might hear!
