W2 setting SWR alarm trip points

[Chuck Guenther]

I just fired up a new W2 wattmeter, and it seems to be working ok,
except that I can't seem to adjust the SWR alarm..

I'm using the W2 utility version 1.3.2.27 and my W2 firmware is version
1.00.  I have the PTT keying cables connected to the W2, and am trying
to set the SWR trip point that will open the amplifier keying
connection.  On p. 8 of the version D2 manual it says I can toggle the
alarm on / off by sending the character "a" to the W2.  This seems to be
working okay in that I get the expected responses "a1," and "a0."

The manual does not specify what the factory default trip point is.  It
does indicate that I can move the trip point up or down by send the
bracket characters "}" and "[" to the W2, and that the response will be
a number with an implied decimal point.  But all I get is 00 in response.

What am I doing wrong?  This is very confusing.

TNX & 73,

Hi Mike,

Thanks for pointing this out.  I did try both bracket characters anyway,
though. I did solve my problem, though.  After searching the archives, I
found that one may need to send repeated bracket commands to the W2.  I
tried this and it worked!  I was able to set my SWR trip point where I
wanted it, at 3.5:1.
