There is about 0.2 dB difference between using one value or the other,

13k is a standard value in the progression of 5% resistors (10, 11, 12,
13, 15, 18, 20, etc.). It is difficult to get 10% resistors anymore,
and 5% tolerance is normally used.
If your local parts source does not have them, perhaps they are only
stocking those values from the list of 10%

I took the 5% tolerance to mean the value is somewhat critical.

If you look at the sheet that came with your TCXO you might notice that
it does a good deal better than 0.5ppm without any calibration over the
temperature range that your radio goes through during operation.

I want to make an observation on the recent discussion concerning the K3 and

The price was right and I carried it home. This is a nice unit and works

hi, fellow elecrafters,
if you should have a problem with the 13 kOhm resistor,
take two.
47k in parallel with an 18kOhm resistor, both SMD, solded together as

It fits great.

The K2 has no provision for aural monitoring of digital mode audio. You
can get that from your computer speakers if you want to hear it. BUT -
that is only for inbound audio, and has nothing to do with the

As a frequent VHF contester, I know what you mean! Fortunately,
there is a setting on the K3 that lets you simply send CW while in SSB
mode, and it takes care of all of the offsets for you! Alas, I don't
recall what it is, but it was added to the firmware several months ago.
Try it!

Maarten,
There are two related but different configuration options for the
situation you describe. The first option lets you use your CW paddles or
key while the radio is in SSB mode. The newer option (so far in beta
