Thanks, Colin: I know one of those persistent stories about SWR is that quote inexpensive meters add forward and reflected power. I did test on a couple of antenna systems matched with an external tuner to 1.0 to 1. Now wonder what price defines inexpensive! Thanks. I am having fun with the new toy. 73 Bob Martin EchoLink Node - 55127 Please visit http://www.wan-leatonks.net. ----- Original Message ----- From: "Colin McDonald" <[log in to unmask]> To: <[log in to unmask]> Sent: Saturday, September 29, 2007 8:43 PM Subject: Re: Initial Tests With My LDG TW-2 > Bob: > I would tend to take the tw2 reading as the more correct of the two. > This because I have never really trusted internal power or swr meter > readings from the radio. > The tw1 and tw2 are very well made instruments and I would bet probably > more > accurate then anything inside the rig. > Also, one thing you must bear in mind, is that if the swr is even slightly > higher then 1.1 to 1, the power reading on the tw1 and I am guessing > probably the tw2 as well, will be skewed slightly. > this could also account for the 10 percent difference. > 73 > Colin, V A6BKX > ----- Original Message ----- > From: "Bob Martin" <[log in to unmask]> > To: <[log in to unmask]> > Sent: Saturday, September 29, 2007 4:31 PM > Subject: Initial Tests With My LDG TW-2 > > >> Well it is here and tested.
