Re: Tempest

Thank you, Chuck.  That is a very kind offer and I so wish I could take you up on it.  Unfortunately, I'm in Houston and won't be anywhere near Herndon this weekend.  Maybe if KLOV holds a party nearer to me, I could get it done then.  It's just hard to justify a $600~$1200 investment in a soldering station for one board.

There is a KLOV party in Herndon, VA this weekend if you are close to that, you can take it with you and get it desoldered there. At least two, possibly three desoldering stations will be there.
