I did what you suggested, and now I'm getting the following error. I think it should
be an easy fix, but I haven't been able to figure out how to correctly install osmosdr
so that it works.

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

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.
Thx
Max

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.
Thanks,
Theresa

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....
Max
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!
