I'll confirm this on the Main RX.
I also have the 250Hz filters. With a similar station very near I could get
up within 300Hz of his signal and still make the DX contact, Fortunately we
are both friends and we were and he knew I was playing with him, His Mk V
just couldn't handle the overload. Only thing the Orion picked up from him
was his clicks and that was not detremental.
The Orion's RX will be a standard for some time to come.

Subject: [TenTec] Orion Main- Sub-receiver differences
Date: Mon, 22 Mar 2004 7:10:06 -0600
I happened to experience a big difference in the performance of the two
receivers in the Orion this weekend. Our club traditionally makes a
"serious" effort in the Virginia QSO Party every year, and a good friend of
mine, who lives about 500 meters from my house was also on the air. We
usually coexist pretty well sharing bands and modes and don't have any big
problems with with interference.
Anyway, I was working 40 CW late Sunday afternoon, and things were slow (as
they tend to be in the VAQP). So I put the subreceiver on 80 CW (LCW, ~1200
Hz BP) to see if there was any activity there while still listening on 40.
Well, I could hear a couple of stations around 3550 kHz, but my friend was
operating down about 3540 and absolutely wiping out the these signals that
were ~10 kHz higher. To make a long story short, I switched the main
receiver over to 3550 (LCW, ~1000 Hz BP), and his signal completely
disappeared. I tuned down to 3540 just to be sure, and there he was at
S9+30, but only in the normal passband of the filter. Awesome.
