John,
the issue with SO2V is that you want to stay on your run frequency, but
be able to slightly tune up and down to hear callers which are not
exactly on your TX freq. RIT comes in handy h
is Excelite.
Yes, if you are working on Japanese radios, you will need JIS.

Good advice on shinny Phillips drivers.
Are the screws in the Elecraft products American Phillips, or JIS
Japanese Industrial Standard?
JIS which all
Elecraft - it may be less expensive than ordering the screws one by one.
Congratulations on finishing the K1.

Hi Don,
Thanks for prompt reply.
No KAT3 installed.
I'm aware that it is not a big deal, it's just annoying.
However, I would like to understand what caused it and how to fix it - if it
is a simple

have to be 1:1. In fact there is a low SWR point where the ATU will not
attempt to tune.
See the K3 manual page 22 and the CONFIG:KAT3 menu (K3 manual page 56).
If you have the K3S, the manual pages may b a bit different.

So now that I have 5 pole filters, I seem to recall that entering the
offset freq is not required any longer on the K3S, is that true?
Also does a K3 upgraded with K3S features need the offset freq?
I should mention
improvements have simply been moved to a lower
priority.

A similar situation exists at the transition between parallel feedline

Thanks to all of for your prompt answers
On CW it works great thanks to the carrier adjustment control
On SSB: it goes to 150W out very easy
Yes it is just for fun.
The K3 is great but the TR7 is funny and special.

I have not switched

The OCF antennas are infamous for conducting RF into the shack.

Not during break in, just sitting there in receive... If the radio is

gives you the voltage seen inside the K3 and if you have voltage drops
at the connectors for the power cable, it will be shown there.
The usual setting for BAT MIN is 11 volts.
You will NOT be "good to go" even if you replace the lithium 3 volt battery.

Dave,
That depends on slow or fast AGC and the setting of the AGC DCY menu
parameter.
Fast is very quick - just watch the S-meter to get some visual indication.

Then check the power supply voltage (Use the alternate VFB B display)

That message has nothing to do with the RTC battery.
There is no internal battery in the K3 other than the tiny RTC battery.

It is a K3

Set BAT MIN for the type batteries used. The default of 10 volts is
good for external Lead Acid batteries. All other types require a
different setting.
