[Elecraft] Has the KX1 changed in 5 years?

[cockpitbob at aol.com]

Greetings all.  I recently fell in love with QRP CW and have outgrown my TenTec R4020.  I'm an engineer and use a soldering iron a lot at work, and I'm busy these days so a build project doesn't excite me. right now.  I have a lead on a 5 year old KX1 and was wondering if they've changed much in 5 years.  I'm fine with little mods and tweaks but want to make sure it isn't dramatically different from the new ones.  Have they changed much in 5 years?

Thanks!
Bob
