BDR seems to be the weak point for SDR rigs.

Larry,
You are correct, any transceiver has problems when being used simultaneously
in close proximity to another. A few years ago our club had a building
project where we constructed several filters for use at Field Day. I think
we were running 8A (100W) that year with all operating
Larry,
I should have added in my previous post:
While the SDR-1000 will experience some overload interference from nearby
transmitters, its excellent hardware design (read wide dynamic range)
makes it less susceptible than many other hardware boxes on the market.

Just wanted to say thanks for all the suggestions and answers to my contesting
question, both on and off the list. I really appreciate the value I get from
this list. I hope to be able to contribute more as time goes on.
Great radio, great group of people!

With the D-44 I have been able to work for example 75

I've never operated in a high RF environment before, so
