On the main System page for the system in question, near the bottom, in the "Radioreference.com" section where "SID" is shown...Trying to download Los Angeles County (CWIRS - Municipal Services) into Unitrunker. I see this is an EDACS system, and I see that the RRDB SID is 341. I know I have to enter 341 when I press download system and the message comes up "Please provide a SID for downloading the system." But I cannot seem to find where I enter the number 341. All the "Please provide a SID for downloading the system." says is OK. Where does the SID number get entered?
