I wonder if Yaesu has changed something. I have a low-serial number
FT-990, purchased a few years ago, and the audio on that thing is also
very hissy. This is the older AC-model that did not have a 12-volt
connector; also came with the ROM that took forever to upload data
(thankfully, I don't use that feature).
Narrowing down the switched capacitor filter helps quite a bit on CW.
I found that is the only way I could tolerate that rig when digging
out the weak ones on CW.
Next to my Omni-VI, the FT-990 sounds _really_ noisy (guess which rig
I use more of now). But the FT-990 is a nice no-fuss rig. No need
to touch up the band-pass tuning when you switch between CW and RTTY,
as you do with the Omni.
