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.

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.

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): 0000000 2e 2f 64 76 5f 74 78 2e 70 79 20 2d 70 20 70 32 0000020 35 20 2d 2d 61 72 67 73 20 e2 80 98 75 68 64 e2 0000040 80 99 20 2d 74 20 2e 2f 31 30 31 31 2e 64 61 74 0000060 20 2d 72 20 2d 51 20 34 33 30 31 33 37 35 30 30 0000100 20 2d 71 20 31 20 2d 67 61 69 6e 73 20 e2 80 98 0000120 50 47 41 3a 39 30 20 2d 76 20 33 20 2d 69 20 34 0000140 30 30 30 30 30 0a On Monday, July 22, 2019, 6:13:53 PM EDT, Bender, Theresa <tbender(a)wpi.edu> wrote: I’m trying to make a OP25 Transmitter with a B200 mini, as in the video.
