Logging functions Q's
by scancaster＠scancaster.net 23 Jul '19

Before I go down a hole and end in a dead end.... I have some questions on using the -L option for "logging." Logging in my universe means logging the audio to Dictaphone/tape/disk/CD/what ever physical media... NOT the -v option, thats a log, not logging! :) ;) So after reading about 30 different files on this -L option, it appers that it will act as A LOGGING RECORDER and RECORD the audio to disk... Great! What I am after is to record UNKNOWN GROUPS for analysis for ID purposes.... My question(s) are what options are used with this for: rx.py trunk.tsv whitelist.tsv blacklist.tsv ie: rx.py example ./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -f 8xx.xxxxe6 -o 25000 -q 72 -L 4 -v 10 -T trunk.tsv -V -2 -U -O loop0 -M mysystem.json -l http:192.168.0.26:8080 -x 3 2>> stderr.2 trunk.tsv then REQUIRES a "center frequency" for the system... 8xx.xxxx based on the channels of the system... I've determined this for this system, and it will just fit the way this is setup. This will then RECORD the various groups that are NOT BLACKLISTED to disk as WAV's from what I understand... Correct???? Ie: OP25 tunes to a group, it records it. Anything that is exlusive of each other on this -L option with other optons for rx.py???? Any thing I am missing in this????? Goal is simple to log any group I've not blacklisted as known user/use.. Thanks.

A couple Q's - RID Aliases? CC Data
by op25＠zellners.com 26 Feb '19

In reviewing the various setups of trunking_file.tsv, id_file.tsv etc... and looking over various documentation, I am not seeing a means to do RID(LID) or Radio ID aliasing... I am I missing this some place??? The systems can be setup to alias out $47E136 as "Helo1" etc... The systems have places to do this from the start and update from consoles etc... Any way to do that in OP25???????? ie: rid.tsv 47e136 Helo1 47e137 Helo2 etc... Turning RID into an alias would be a plus to ID units... ie: Ladder1, Ladder1_Portable, FF152521, etc.. Many of these are pretty static.. now some depending on you agency(s) may not be... in on a particular group would need some updates each year, as they change based on a progression system. CC Data is there some sort of aggregate that determines the quality of the CC data coming out???? That can accessed programmatically??? Or maybe that question is better referenced as is the there something that documents the API to OP25 that the various python scripts are using to possible do what I want... The plots are not useful as I desire text data to use in another place.... So I guess something that documents interacting with the underlying mechnations of OP25 would probably help to do what I am after with the CC. Thanks.

Audio Dies Pt2 and JSON meta tags????
by op25＠zellners.com 25 Feb '19

As the next round of P25 PII systems take hold in my area... OP25 is the goto solution... but... Audio dying is not a good thing... to send out silence on feeds.... Seems this is related to the metatag update when using -M tags.json option with rx.py... Whats frustrating is Pi3B+ with a cheapo junky asian dongle WORKS with -M tags.json and the audio goes on... .. I have another issue not related to that, which a commit fixes, just can't update to handle that right now... A DUAL CORE laptop with a junk asian dongle... the audio dies after awhile. SAME DUAL CORE laptop with a V3 Blog dongle... audio dies after awhile SAME DUAL CORE laptop with V3 blod dongle, REMOVE the -M option and the audio seems to be stable out to loop0! URRRGGRRRHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH! The only thing I can seem to possibly pinpoint is my standard A1 whipping or flogging boi,,, puslecrapdio! RURRRRRHHGHHH! The laptop has it the Pi3 doesn't.... Any one else seeing similar ? ? ? ? ? Once I have a new image setup for my Pi feed boxes.. and if that works reliably great...it seems to on my existing feed, other issue not witstanding..... Jusy annoying that a laptop has these issues where as a Pi3B+ doesn't...... I am grasping for answers here... and as I said... my standard A1 whipping or flogging boi,,, puslecrapdio! just gets my attention and foucs as the problem area. So to wrap up my screed and vent BS post.. .:) ;) Any seeing similar with xUbuntu's 18.04 or even other distros on lap/desktops v. Pi3B+??? Welp... there goes my theory in the time it took to type this OP25 is now not playing audio out loop0 again, and no -M option was used.... CC channel did rotate... (Harris nee M/A-COM system)??? So maybe CC rotation kills audio ? ? ? ? Any one with ideas? ? ? ? Bueller????
