 OK that doesn't appear to be a current version of OP25.
The line in question 
    if options.protocol == 'p25':should instead be    if options.protocol == 'p25' and not options.test:
That line is correct in the osmocom version of OP25 (branch 'max').
Suggest that you try something like this
   cd to your current top-level op25 directory        [the directory named 'build' should be a subdir of this]
   cd build   sudo make uninstall
Then clone the repo 
    cd ~
    git clone https://git.osmocom.org/op25
    cd op25    git checkout max
Then run the install.sh script from there......

Here's the command that i typed: 

./dv_tx.py -p p25 --args 'uhd' -t ./1011.dat -r -Q 430137500 -q 1 --gains 'PGA:90' -v 3 -i 400000

Here's the output from that command:

Here's the results from the command to verify the code level:

Subject: Re: [op25-dev] Attribute Error: 'file_source_sptr' object has no attribute 'set_gain_adjust' OK, did you receive a backtrace in addition to that error message?   If so, could I have you paste (not retype) the entire sequence, including the full command that was typed and the full backtrace?  The set_gain_adjust() operation should really not even be getting invoked in the first place since you're using the "test" (-t) option . . . .

Also, let's have you verify the code level of OP25 that you're running - please issue the command
    git log | head -15                 [from within the OP25 directory structure]
and include the results.

Hi Max, 


Thanks so much for your reply. I’ve been emailing using a different computer (Windows) than what I’m running the TX on (Linux). I had quickly typed out the command line on this email so you’d know what command line I was talking about. I just verified it on the Linux, and they are all single quotes and I do have the unquote after the PGA:90.

Hello Teresa


We don't have a huge number of success reports for the TX - so accordingly this is high priority and I'd very much like to get it nailed down.  Looking at the command line, I copy/pasted it into a terminal and some of the single quotes appear to have pasted as strange backtick characters (‘) rather than as single quotes (').  If these characters actually appear in your command (as opposed to being an artifact of copying/pasting) they will cause trouble.  Looking at these characters on-screen they also appear incorrect, but I need a magnifying glass to see them in detail.   Could I have you try fixing this first before we proceed to look at the actual error message.   Noting also that there should be a matching (un)quote following the string "PGA:90" that also appears to be missing lends some additional corroboration to the possibility of a malformed command line....




p.s. I ran the results of the paste thru "od -t x1" and there appear to be several non-ASCII characters (anything greater than or equal to 0x80 is invalid):

I’m new to using SDRs and the B200 mini, so I’d appreciate any advice! Thanks!
