Reply to: RE>>FT-990 noise floor
Joe, I also have an older 990. There is no DC connector. Can you tell me who
you contacted to receive the update bulletins and parts?
Thanks

Kok,
My FT990 is apparently the same vintage as yours. I bought it used and it
had no DC connector. I contacted Yaesu and got all the bulletins regarding
upgrades and modifications, including some diode changes. I ordered the
needed parts and up grade the unit. The ROM has to be upgraded by Yaesu, but
they will do it free. You need only send that card in, not the whole radio.
My service manuals and bulletins are in Indiana, so I don't have them here
for more accurate information.

I have the 250 Hz filter and still need to use the digital filter from time
to time, but because of air noise, not the radio's noise. I have dug out
signals that were not perceptible with out the digital filter.

I wouldn't trade my FT990 for anything, except, maybe, an FT1000D, maybe....
