Thanks folks!! I so much better understand now what I am looking at, really appreciate that. Will have a dummy load arriving any day now.... ?

The only thing I changed was the channel frequency, to get those two different readings, using that small antenna that came with the MXT500. Whatever ohms that antenna represents... I take that this is "normal" to see, that the further the frequency gets away from the ideal tune of the antenna (higher SWR) that the power shown is not the actual power of the radio that is displayed? If so, to determine the actual power the radio is by getting as close to 1:1 as possible.. Right??

I am testing my radio, using the antenna that comes with the MXT500, using a DuraComm LPX-25 (13.8v 26A) power supply.. On my Surecom SW-102 on freq 462.700. I get SWR of 1.00 and 41.02W output... But on 642.650 with an SWR of 1.96, it shows it is putting out 49.69W? See photos. Isn't power supposed be less from the transmitter with higher SWR? What can you guys teach me.....

Marc, Did you get your radio back yet? Results? I sent mine back (only getting 30W) and still waiting....
