[Elecraft] Wattmeter Calibration

[Geoffrey Downs]

In my view the manual is not wrong in that respect. It tells you to set the 
TUN PWR menu item to NOR before you start.

However, I have always found a different problem. The last step of the 
procedure tells you to hold TUNE and adjust the menu parameter (WMTR: LP or 
HP) for exactly 5w or 50w. But holding TUNE takes you out of the menu. So I 
adjust the menu parameter when the K3 is not txing and then hold TUNE again 
to see what the effect has been, repeating the process as necessary to 
achieve 5w or 50w. Anyone else see this? Or have I been doing it wrong these 
last 5 (nearly 6) years (quite possible hi).

73 to all

I finally figured out what was happening. The procedure in the manual is 
wrong!

On step 5, the power is set by the FRONT PANEL POWER CONTROL

On step 7, TAP tune, do NOT hold it. If you hold it, you get the tune power 
which
is a separate menu item.

To key the tx in CW I had to insert a shorted plug in the key jack on the 
rear
panel.

The WMTR LP menu item is evidently controlled by the circuitry that switches 
the
100 watt PA in and out. If the power control is set above a certain level, 
the menu
item switches to WMTR HP.
