    Um, Larry,

    7.0 to 7.3 METERS?!?

    I guess you are really excited about this radio. 😉 It’s all good. To err is human, to really FUBAR everything you need a computer…


  • Larry W2LJ:


    The data was obtained from the LNR Website.

    It’s quite obvious that they meant MHz, eh?

    For TWICE the money you get a KX3 and 10+ times the rig!
