hello tom, do not pay any attention to the ldg pw1, it is a very in 
accurate device.  its readings are frequency dependent and even 
though they say that it will handle a kw on 50mhz thats not true.  i 
purchased a pw1 and compared it to my byrd 43 wattmeter and it was a 
joke.  and on 50mhz i ran a kw through it and in a flash it went up 
in smoke.  i spoke to ldg and was told that the unit will not handle 
a kw on 50mhz  even though they claim that it will.  i think that 
most folks on the list are using a pw1 and put way to much faith in 
its readings.  it is just a relative device and a very poor one at 
best.  the rf applications unit was a much more accurate device and 
was not so frequency conscious.  take care, c u 73 mike w6quv
