Hi
     Generally, to get the most accurate measurements one will want to use
CW, FM, or AM. These all give a solid carrier. ON AM though if there is any
sound going in to the mic it will throw off the readings.
     The other thing to consider is if perhaps you have a loose connection
in the antenna system somewhere. They can sneak up on a person.

God bless,

God Loves you!

Subject: using a tw-1?

Hi all,
I've just gotten a tw-1, have it connected, and the thing is talking as it
should.  However, I'm quite startled of the inaccuracy of the readings that
i am getting.  Sometimes, I will see my antenna 250:1 etc.  This doesn't
make any sense at all.  Sometimes, I will see my power output at 130 watts
when my radio actually puts out only 100.  I'm using this with a Kenwood
ts2000.  Can you help?  I'm not expecting this to be as accurate as a bird
watt meter, but I would imagine it should be relatively accurate.  Also just
to clarify, you can just hit the forward, reverse, or swr button while using
an SSB transmission?  
Thanks much,
Justin
