I saw at http://www.radiointel.com that Liypn told Russ
eBay has stopped allowing the word "Degen" to appear
on eBay auctions, due to a complaint by Degen. Not much
information other than that.

I went to eBay and checked Liypn's auctions. Sure enough
he's selling DE1103s etc. with no mention of "Degen". Then
I checked Brochhi's stuff. He's still using the Degen name.

Here's what it says at radiointel.com:

Ebay Bans The Use Of The Word "Degen" On Auctions
Thanks to Ebay seller Liypn we learn that Ebay as prohibited
the use of the word "Degen" on their auction site. This is result of a
complaint filed by Degen GmbH Communication with Ebay as
unauthorized use of intellectual property rights, copyright, trademark, etc.

Does anyone know why this happened?
