For several years, I ran SO2R with 1 KW to yagis on my tower and 100 watts to an HF9V on the roof of my garage. They were separated by some 250 feet, and both receivers had RX protectors in the RX antenna line, but it worked OK. Had to stay well away from harmonic frequencies, though.

Most station combinations used to simultaneously listen and transmit will use 
at least some additional filters to reduce cross-band interference.  Long years 
of experience at the under-100-w levels on Field Day suggest that it isn't 
enough to count on horizon vs. vertical polarization to reduce signal.  Filters 
provide easily 30 decibels of additional attenuation and are important to your 
results.

I'm new to this email group...

Can I start SO2R contesting...with no major problems...with only >>

- 2 CAT controlled Radios
- dipole ants (rig #1)
- multiband vertical (rig#2)
- DX doubler (audio controller)
- low power...under 200 watts

How can I make sure I don't fry the Rx front end(s) ?
If I add soft rock SDR to monitor "band openings"...how make sure I don't fry 
soft rock rcvr as well ?

I believe dipole & vertical with
no-coupling is ok.
(Horizontal vs. vertical polarization)
I don't believe band-pass filters are a must until power is 500 watts or more 
(?)

Thanks for any practical advice/inputs.
