John,
While I own and love my TX-500, it is definitely not a CW-Learning type of Radio for new Hams!
If I were honest, I would say the TX-500 is more a 'custom-radio', designed specifically for outdoor (field) use and has a 'less than most' accessory list!
I also have "Elecraft KXLine" and would seriously suggest you consider this route - A KX3 has everything they need to take them (and you) from Home-Station to Camping Trips!
Its a breeze to operate Digi-Modes (with or without an interface like DigiRig) and the Internal ATU will effortlessly load up a simple wire antenna, bed-spring or variation..? ?
"Made in USA" and support is just a phone-call away!
You wont regret it!
