Ron,

Sounds good to me, in fact quite good.

One of the items on my "wish list" for the Orion II is to fix the AM receive audio, which sounds to me like a problem in the DSP code that causes distortion and 'muddy' sound. It's most noticeable during selective fades that cause a serious clipping effect. Last night, I made an MP3 of a local AM radio station comparing the O2 to a TS-870, and sent it to TT service. This morning, TT said they couldn't hear any difference between the two receivers. Is it my ears or what? The link to the clip is below. The O2 is the first 60 seconds and the 870 is the second 60 seconds. Bandwidth on the O2 is 6 kHz, while the 870 is 3 kHz, although as you'll hear, it sounds just the opposite!

Can anyone besides me hear the difference?
