r82xx_set_freq: failed=-1 [3 Attachments]

Greeting all, I am able to establish a op25 Receiver but, it does not tune to the correct frequency, I believe that this is because "[R82XX] No valid PLL values for 2293470628 Hz! r82xx_set_freq: failed=-1" My command line is: ./scope.py --args 'rtl=0,buflen=65536' -g 65 -f 851.18750e6 -N 'LNA:49' -V -v 0 -S 288000 -q 39 -T trunk.tsv I am attaching my trunk.tsv file and the error from Terminal. I also have a concern about the NAC of the group that I want to follow, on RR, the "System ID" is 348, 5A1, and 649. The WACN is BEE00. I am interested in the Cincinnati / Hamilton County system. On the UniTrunker setup, the NAC is showing as 342. Any help would be appreciated. Mel

Wireshark P25 patch
by 'Rucker, Karen (Assoc)' karen.rucker＠nist.gov [op25-dev] 30 Jun '16

30 Jun '16

I've been attempting to modify Wireshark to sniff P25 packets a la http://op25.osmocom.org/trac/wiki.png/wiki/WireSharkPage. I have the same version of Wireshark that the patch is made for, 1.8.5. My latest issue is 9 "redeclaration of enumerator" errors that come up when I attempt to compile Wireshark w/in Fedora. I have no idea where in the patch these are even declared. Any help? Sorry if this is a repost, I can't see any prior messages. Karen Rucker Intern National Institute of Standards and Technology - NIST | CTL | PSCR 325 Broadway, MS 671 | Boulder, CO 80305

Well i finally got scope working, turns out the problem was when i plugged in my rtl it installed the dvb driver, so I had to use the sudo rmod probe command and remove the kernel I have scope up and running , I want to listen to 139.5600,(mhz) its p25 1 non-trunked, but I cant seem to find it with scope, and my fft plot is in khzAny sugestions on what to use for a ./scope command? Im using ./scope rtl=0 -f 139.5600M Did anybody get the grc file I posted to work?
