The poor mans Flex Radio

A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.

Many WebSDR Nodes are available around the world

A WebSDR server consists of a PC running Linux and the WebSDR server software, a fast internet connection (several hundred kbit/s uplink bandwidth per listener), and some radio hardware to feed antenna signals into the PC. This radio hardware is typically a quadrature mixer connected to the PC's soundcard, like the popular SoftRock kits.

The first K5BAY tailgate sale is over…

Saturday, 16 October 2010 18:06 by G7EIX

And I am sure all will agree that it was a great success.

We had well over 20 sellers and a very good number of visitors and friends turning up from 7am in the morning.  Personally I like to open the blinds and see daylight, but this morning it was still dark when I climbed from my pit to make my way into Baytown.

Anyway, it was a good first event and I am told that this will become a regular occurrence – possible once a quarter from now on.   That may change, but keep an eye on the K5BAY website, group and blog for up to date information.

Here are a few photos from today.
