Hi all,  I got in an FT-1000MP Mark V Field and output is normal on the low bands but drops off as you go up the bands:

Approx
1.8mhz    125 watts out
3.5mhz    125 watts out
7mhz       70 watts out
10mhz     45 watts out
14mhz     40 watts out
18mhz     35 watts out
21mhz     35 watts out
24mhz     30 watts out
28mhz     20 watts out

Same in FM/CW/SSB, Ant A or B, tuner NOT on, did CPU reset of course.

Using an accurate dummy load that works 100%. Other radios I have show full output on all bands using same equipment, problem is with the radio

Anyone familiar with the Mark V Field that can help?

Thanks,

I didn't check the other reference, but it sounds like the PA low pass filters aren't switching correctly.
