For the last 3 days or so i no longer pick up site 8 Niagara falls or site 23 UB cooke hall. Upon playing with the sds100 i discovered site 8 control channel of 461.975 cc8 would show up for less then a second and disappear. I have the hold time set for 5 seconds. I did a "search for" and entered in 461.975. It shows cc 3 on site 23 which is UB cooke hall. According to the database that freq is not associated with site 23. IT is on site 8 niagara falls. IT seems like the control channel for site 8 has been relocated to site 23. Has anyone else having issue with these two sites or know if they changed frequencies on these two sites?
