Hi John, that is fantastic!! I have never experienced anything near what you

Hi Wayne,
I enjoyed your 2018 Field Day report, especially the part about your solo trek
with the KX2 and the prototype 2-band, 4’ antenna.
For the KX2 with the short whip, please tell us what bands you operated on and
what you used for a counterpoise.

Your proposed speaker looks interesting. Thank you for offering it.

Dear KX2 or KX3 owners,
If you own a KX2 or KX3, do you find that the built-in speakers produce sound
of sufficient loudness and good intelligibility?
I do not (yet) own one of these fine radios, so I must ask others for this
information.
Thank you and 73,

Dear Elecraft Friends,
Up through last weekend I had been operating my K3 #820 with MCU 4.31 and DSP

performance, and saw no reason to upgrade.
But Reflector reports praising recent improvements in NR and NB operation
