[TenTec] Scout

That reminds me of an old Triton digital I had the occasion to "play with."

It had a number of spurs that were annoying so... long-short...  the digital
counter display was the culprit and a makeshift faraday shield was created
around it.  That reduced the spur levels enough that they were no longer
bothersome.
