Ditto here. My 13-509 never suffered any ills for over 20 years continuous repeater operation and it was an old original brown face model. No external BPF on front end, an 80 dB null set of duplexers with a 6 dB antenna on a tower that had 450 MHz, 800 MHz, 900 MHz and 150 MHz systems running 50 to 100 watts and pagers up to many 100's of watts on antennas just above the 220 antenna. Never heard a peep of Intermod. Never used PL. A 0.2 uV max. signal produced a noise free signal out of the receiver.

I completely disagree. I've built a couple of 13-509 systems & continue to service a couple of others. Given what it is, it performs exceptionally well. I have one literally sitting in the middle of downtown LA @ 1000 ft. AMSL with nothing but a notch duplexer between the RX & the antenna, & it hears quite well with no IMD.
