[Yaesu] FT-897D transmitted noise

[Deon Erwin ZS1ZL]

My FT-857D once behaved strangely and transmitted harmonics out of band.
I  performed a master reset and all has been perfect ever since.

I just read something about that on one of the lists and I
thought I'd saved it because it applies to the 857 as well.
Anyway the gist of the post was that turning on the  receive
digital band-pass filter noticeably reduced the  transmitted
noise. It went on to describe setting the HPF and LPF
frequencies to minimize the BPF effects on receive.

I don't know if it works, but it doesn't cost anything and can't
or shouldn't hurt anything so give it a try. I'll see if I can
find the original post so they can receive the credit.
