I am using an Astron SS30. When its fan comes on, it is a little noisy, but
even in contesting activities it is running less than 50% of the time. I
can hear some RF birdies from it, especially on the AM broadcast band, but
they are not that hard to avoid. I bought it when I bought the FT950 4
years ago.
