My K2/100, SN 3777 works great. No complaints
However, I am a bit leery of the indicated SWR.
The indicated SWR seems to tell me that my antenna match is better in
nearly all cases than several other SWR and power meters I have
laying around.
When SWR is measured using a MFJ 962 tuner, a Daiwa 101N meter, a Bird
43, Autek RF-1, or a MFJ 249 analyzer, the indicated SWR is always higher
than that shown on the K2.
For example, pressing TUNE on the K2 may indicate a 1.0:1, but the other
meters all consistently indicate a value significantly higher - lets
say 1.4:1
If I happily ignore the other SWR measurement tools, and only use the K2
SWR indications, everything still works great, I make lotsa contacts and
all is well.
However, at the home QTH, I do have a fairly well matched antenna, and I
do know that it is resonant in the band segments that I work.
Taking he K2 into the field is another question altogether. At this
point, I don't trust the K2 SWR readings and have been dragging along
other SWR meters when loading a temporary or unknown antenna.
Please advise.
