I know that a while back there was a grc flowraph of op25 that handled DES. Any chance of a pybombs recipe for op25 that handles RC4 as implemented in Advanced Digital Privacy?

balint256 op25 repo is several commits behind the osmocom.org op25 repo

by ikj1234i＠yahoo.com [op25-dev]

Greetings It looks like the balint256 'op25' repo tracks the op25 repo at op25.osmocom.org only up to commit 2051a96198c. The op25.osmocom.org repo has more than a dozen additional commits beyond that, which means that the balint256 op25 install is approx. one year out of date. All of balint's changes don't affect the op25_repeater, so there shouldn't be a big hassle when the time comes to merge everything into master. It looks only like one or two CMakeLists.txt files might have merge conflicts, YMMV. Accordingly, I recommend as follows (until such time as the merge may happen) - use only the op25.osmocom.org build when running scope.py - use only the balint256 one with balint's associated changes - keep them otherwise separate Max ps. Knuckle Punch to Balint!!

p25_frame_assembler performance problems

by lukekb＠gmail.com [op25-dev]

I am trying to record a Phase 1 P25 Trunking systems. I have a bunch of OP25 records hooked up to the different channels that the system could use. I have a Valve in the flow graph that will allow samples to pass or dump them to a null_sink. This lets me turn P25 recorders on or off. The problem is that the recorders using OP25 seem to using a ton of CPU even if they are not getting samples. I tracked it down to the p25_frame_assembler block. Whenever it is connected to a flow graph, it seems to be using a lot of CPU, even if it is not getting any samples. Any ideas why the p25_frame_assembler block would be using CPU cycles even if it is not getting samples in? I am running it with the following params: bool do_imbe = 1; bool do_output = 1; bool do_msgq = 0; bool do_audio_output = 1; bool do_tdma = 0;

Ok I know I asked this before but im still stuck, why when I launch op25_25.PY I just get the waterfall app, im using the black rtl sdr how do I tell it to tune o a frequency? Where could I find the op25.grc file and just run op25 in gnu radio companion? Yea I know, I suck, I ask alot of dumb questions , but im tryin! Cant wait for the live cd to come out!
