[VHFcontesting] ARRL June VHF QP Participation Question

[Floyd Rodgers]

I have 847 857 and 817 and all are dramatically better in crowded band 
conditions with the collins mechanical filters installed. In my opinion 
the filters are worth the money and all the rigs hear well on 6, 2, and 
uhf. Digital rigs like the ic7000 IC7100 etc don't use filters. You will 
need to learn how to optimize your receivers digital front end.
