When I built a single level paddle, I decided to use silver for
the contacts after hearing that all the corrosion products of
silver were conductive. I soldered two short pieces of silver
wire, contributed by a jewelry maker in the family, at right
angles to each other on the contact bases.

Don't forget that the balun may be breaking down with power and show no

No, that’s not it. The right is ALREADY in split mode when i attempt to use the

You get the N/A flash if VFO A and B aren’t set to the same mode, other than

I have a 9700 and since it looks nearly identical to 7300 assume the UI is
similar. Intuitive? Not at all. K3 has lots of buried items but they are easy
to find and mostly set once & forget. Only gripe would be all the
abbreviations, but that was obviously limited by a practical display choice
Hi Don,
I just tried the same Macro (TU DON CWA) and sent it a few dozen times and it
completes each time with no problem. Have you tried re-entering the Macro in
another Macro slot. Can you describe what happens when it stalls? Does the
displayed text in the text fields complete?
David,

OK - general consensus is that it is working as is supposed to. I guess someone
slipped me some whacky weed when I wasn’t looking. I’ll crawl back in my hole
now. :-)

Nope, that red line should move off to the right on the P3, just like it does
when the XIT is enabled. What happens on your P3 when you turn on RIT on the K3
and true the knob to increase frequency?

I didn't get any response to my query below, but I have a solution in place
finally. I'm no electronics wiz but I found some circuits and constructed
something based on a 555 that works nicely. If any else is interested in
this, let me know.Dana

Thanks everyone! The Ref Lock board was included with the kit I purchased! I
was too dumb to know it was there!
Thanks and 73

As is often the case, connecting directly to the battery for the negative
lead is misunderstood. In today's world, it depends. The Battery
Monitoring System (BMS) is a big deal in most of today's vehicles. To
function properly, we should NOT CONNECT to the battery's negative terminal.

The K144RFLK is showing as available on this page. However, clicking the
item takes you to a page suggesting to “signup” on an interest list.

Also, to use an external 10MHz reference, K3EXREF is required.
My K3S is currently in
OK, I am curious…
Why was not this reference clock board not built into the 2-m option board in
the first place. Overall I can’t imagine that the net cost would be as much as
designing and separating out an optional PCB and all that goes along with that
as the combined cost of the 2-m option

It is "highly recommended" (was), so that IMPLIES that the 2M module can
be used without it, but at some sort of reduced accuracy in frequency I
would guess.
My 2M module install turned into the need to ship it in and
