So now that sds100 is here and will be getting at least one more x36 model, ive been trying to decide what to do with my other scanners. I decided to take my aor8600 and program for summer listening like USCG, marine channels, etc. Sometime ago a friend challenged me to add the p25 pcb option to my aor like he wanted to for his. Only mine was the test model first. Lucky for us electronics and radio are my life and career. I installed the modules with success and the p25 sounded great, so this helps with monitoring USCG astro. Now if i could just decide on the others??
