[1000mp] SWR Meter and FT-1000MP

[Pawel, SP7PS]

Hello FT-1000MP Users,

Because I have problem with one of my antennas I wanted to check, if the RF
cables between my MP, FL-7000, external SWR Meter and antenna box are right.
I put 50 Ohm dummy load instead of antenna and made a test. And it was a big
surprise for me to see difference between MP's SWR and external YAESU YS-60
SWR meter. First I tried with 50 Watts and external SWR meters shows 1:1.
But MP shows 1:1.3. So I increase the power to 100 Watts and external SWR
meter still shows 1:1.0, but internal rised to 1:1.7. Is that something
wrong with my MP?

What is your opinion or suggestion?
