Band pass filters in multi-radio environment

I haven't quite found the answer to my specific question. I will be doing small 2 radio expedition. The second radio, not a flex, will be running 500 watts and will have its own 150 BPFs between radio and amp. I will be running the AU520m. Do I need separate BPF's in this environment or are the internal BPF's in the Flex good enough?

The secondary issue is if I have to use external BPF's, i will need the big, high powered, filters which will take up too much space, since I will be running 500 watts from the AU520m.

Please advise.

    Hi Mike, the BPFs in the 520 should be more than adequate. They are 7th order filters good for 50 + dB of out of band attenuation.
