It should be good..............I am shooting for a +40dBm IP3 on the loop

Cool!

About that 6790, the IP3 on that unit is rated at +30dBm, which
isn't bad, but they do have a wide open front end.

Yeah. I know it has a pretty solid front end, but no preselector.
I'm just returning the favor for phil needling me. The only real
problem with that receiver is that it generally is bare-bones when you
get it and you have to fill out all the filter options.

Still, I haven't had any
overload problems with mine. It is my favorite receiver, but it so is
BIGGGGGGGGGGGGGGG. Maybe, when I buy a house, I will build a nice deep night
table to keep it on. When you open up the 6790, you see that the
construction is very good. All of the RF modules are enclosed in a die-cast
"egg crate construction" style of assembly. The 45MHz I.F. filter is at
least 8 poles, so the 2nd mixer is protected quite well from out of bandpass
stations. I got mine from Ken G. down in St Louis. He is a great person to
deal with.
