Hi, thanks for all helpful advice on antenna separation etc. but I have a problem with my FT817 on 70cms (5 watts) de-sensing my FT-480r on 2 meters. I have managed to stop the 2 meter transmission blocking the 70cms reception but I find that with even 5 watts on 70cms this is still de-sensing the 2-meter radio, any ideas, or links to some good band pass filters (low pass or high pass that you may think will work?) regards Gus M0IKB
