Does Wayne have any goodies for us as we wind down to Field Day? It

Everything is so quiet. I guess its time to make 3.14 production.

Hi Tony,
3.14 will be going to production shortly, and there will also be a new
beta firmware release in the next day or two.

To make this even easier, seeing the station you wish to work, with miles,
short and long path, location and beam heading etc, order Comm Cat and
really enjoy ham radio. When I see the station I would like to work, I
click on that station and it changes the K3 to that freq and all the
setting.
Oh boy, this is fun!

Truly smart chargers such as those using the uc3906 IC understand this and
adjust accordingly.
This does presume that the IC and the battery are located in the same
environment, which isn't always exactly the case, but often close enough.

A few countries allow experimental amateur radio operation in the 500
kHz band (600 meters). This is a fascinating and historic band that is
used for beacons and ground-wave communications. For hams, there are
very specific mode and power restrictions, and an experimental license

500 kHz is near the top of the 600 meter marine band which extends down

Of course, once you get to 400 kHz there are those who love spooking the

Hi Everyone,
I am about to perform some overdue mods on my K3 #371.
I notice that this mod (Rev B FP Modification for curing Hang VOX
problems) is required for K3 #'s 660 to 782 but not on those before or
after this range.
As I will have the FP off and the DSP board removed should I do it
I guess I'm confused as to why it does not apply to earlier K3's
The earlier K3s had a capacitor hand-soldered to the FP board. Later,
the capacitor was added to the FP PCB layout, but an error in that
layout required the jumper to correct.

It's great they're keeping it alive for newer Hams and radio buffs in
general. Be sure to drop RD an e-mail saying you appreciate it and don't
