May I suggest that if you have nothing constructive to say, don't.

Re: COLLINS FILTER YF-115S-02
Thank you Richard. I was aware of the FT-1000 MP using the same filters.
I happened on to that same site as the link you sent to me.? I may

Re: COLLINS FILTER YF-115S-02
Hi Butch, i'm not sure if you know but the filters in an FT1000MP Mark V are also compatible in the FT847.? This might expand your ability to locate one.? I searched a long time for the 500 Hz CW

Re: loss of hf+6 tx
Hi Shayne, what current does you 847 take when transmitting, at minimum power out?.

I suspect you have a blown HF P/A unit.
