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 trying to make a OP25 Transmitter with a B200 mini, as in the video. I’m using the
same command line as in the video (./dv_tx.py -p p25 --args ‘uhd’ -t ./1011.dat -r -Q
430137500 -q 1 -gains ‘PGA:90 -v 3 -i 400000). I keep receiving the error “Attribute
Error: 'file_source_sptr' object has no attribute 'set_gain_adjust'”.
I’m new to using SDRs and the B200 mini, so I’d appreciate any advice! Thanks!
