The FT-950 is an amazing radio except for one complaint, the audio stage hiss and you'll be surprised to know that it can be fixed EASILY. To make a long story short, Yaesu messed up in the gain distribution in the different parts in the audio stage. The final amplifier is built around the excellent Sanyo LA4425A.

If I press the front panel Power button momentarily, the audio is completely muted for a few seconds and I hear a couple of relays click.

This is audio low/ground. The FT-950 and some other Yaesu radios are very susceptible to RF affecting the transmit audio. I noticed when I operated on 75 meters (I do maybe twice a year!), I heard RF when using the amplifier.

I purchased a Yaesu FT-990 several weeks ago, primarily for the fine ergonomic design. The rig worked well, but then I discovered the infamous receiver audio hiss discussed in various forums. Turning on the SCAF filter changed the sound of the audio hiss, but the hiss was still there.
