FT-857 and QRP ?
 

I want to work QRP 5W output on my FT-857.
SWR is close to 1:1.
If I set power to 5 on FT-857 (in menu I can choose from 5 to 100) my
Pyramid SWR14 shows RF output 1W.
If I set power to 15, Pyramid SWR14 shows 4W.
Can I trust to Pyramid SWR14?
I don't want to work QRO and to give other HAMs /QRP.
Can someone who owns FT-857 and accurate RF power meter test the output. If
I select 5 is it 5W or 1W?
Thanks in advance for reply.
