Hi all...
Another choice might be something called REW (Room EQ Wizard) which is an AMAZING, free program that is Java based, so it should work across different platforms. There is a Mac dedicated version, but I know little about Macs, whether yours might be compatable or not. It is a very capable and complex program, originally designed for EQ'ing speakers and subwoofers with your room, for good, balanced bass. It of course, has a very capable audio measurement and spectral display capability, with a whole lot more. The designer has been adding things as he's been working on it for a long time now, it has a pretty amazing list of features, especially for a free SW. Beautiful and flexible graphing, I might add. Check it out, help files are pretty good. Might be a little daunting, but you won't be needing to deal with some other things that would be part of a usual setup. You don't have to do any mic setup and cal, of course, since you're not measuring room responses, and it's pretty basic to just get your rig speaker output into a computer line input, to measure response like with Spectrogram. Of course, you could use the built in signal generator to put pink noise into your mic input to measure your TX response, as a more advanced usage, later perhaps.... https://www.roomeqwizard.com/ is the site. There is a pretty active forum on a site called AV Nirvana, used to be you had to make an account there to download REW, but he now has the stand alone site. Worth the signup to get on the forum if you need to post a question, they've never bothered or mailbombed me.

Thankyou to everyone for ideas. In the end, I found a version of
Spectrogram16 which worked first time under Windows 10 running with Parallels on the Mac. I had forgotten how much of a joy it was to use when setting up the filters. 73 Ian On 22 Feb 2021 at 01:52:44, Jon <[hidden email]> wrote: > Hi all... > > Another choice might be something called REW (Room EQ Wizard) which is > an AMAZING, free program that is Java based, so it should work across > different platforms.
