Shimming.

I mentioned SHIM6 way back in November 2006, when I was working on a project where we were doing an ‘initial look’ at SHIM6.  Well now I’m back looking at it again for a different project. So I  have been putting together a testbed here in  TSSG in order that we can complete a fuller analysis of  Sébastien’s implementation.

Unfortunately I’ve not really got ‘decent’ results yet due to a ‘comedy’ of failures of older hardware that I have re-tasked for the job, and there’s one pesky bug that we haven’t quite found yet that is disrupting things, but hopefully I’ll have more ‘interesting’ results in the relatively near future.

So far (pesky bug allowing), the fail-over aspect seems to work quite well, which is very very cool when you see it in operation.

Hams Called to Action!

From the ARRL NEWS:

“On Monday, May 12 at 0628 UTC, a magnitude 7.8 earthquake hit Sichuan, China. The Chinese Radio Sports Association, the Chinese IARU Member-Society, has designated the following frequencies for emergency services involved in the rescue: 14.270, 7.050 and 7.060 MHz. The ARRL encourages US amateurs to be aware of the emergency operations on those three frequencies.”
