[Elecraft] Calibration of KXV3 module

[James Sarte]

Hi Stephen,

 

Yes, I'm familiar with 50 ohm BNC network terminators.  This will work
without issue and get me properly calibrated?  Otherwise, I can always get
an SO239 to BNC adapter and run a cable into my 300w 50 ohm dummy load.

James,

It will only (possibly) be 50 ohms at the frequency for which the stubby
antenna is designed, which will almost certainly not be the frequency coming
out of the XVTR jack, so it won't work.  I expect a 47 ohm resistor would be
close enough, but ideal for this purpose would be a 50 ohm BNC termination
that used to be used in pc networking if you are familiar with that.
Otherwise a coax cable (via adaptors if necessary) from a good dummy load to
the transverter terminal would be fine.

Hope that helps

Dear group,
 
Page 50 of the user manual states that a 50 ohm resistor should be attached
to the XVTR OUT jack for calibration.  If I don't have a resistor, can I use
a 50 ohm BNC stubby HT antenna instead since output is only 1 mW?
