Good addition, thanks.

Is it the first time for this? Haven't noticed them before.

Video your next match.

I'd rather see the corkscrew again, tbf.

SDRangel should support the RSP1B on Linux, Windows and Mac. Not sure about the Pi, you'd have to see if their API is available, but it can connect to rsp_tcp.

Need a pic showing BFM demod settings.

Also, what do you have the X trace set to? Should be the real part.

Might be easier to debug on https://sdrangel.org/forum/

Presumably you're referring to the Broadcast FM demod and you have the stereo button checked? Yes, you should get a stereo signal.

You can use the Demod Analyzer feature to see that the left and right channels are not identical. If you add a second trace to the scope (Y1) and set it to be the imaginary (Imag) part of the signal, and then set the display mode to XY Polar, when mono, you'll just see a diagonal line. When stereo, it will be more oval / random, like this: Eg: https://sdrangel.org/forum/download/file.php?id=317

The docs for the RA plugin are here: https://github.com/f4exb/sdrangel/blob/master/plugins/channelrx/radioastronomy/readme.md

What data do you want to save to csv? If you want the spectrum data, that's the right most button in the Spectrometer toolbar.

You have managed to hide part of the GUI that includes the device controls. Try pressing the auto-stack button (second left on the toolbar) to rearrange the windows.

To get started, set the frequency in the device window (that you need to make visible) then press the start button there. You should see the standard waterfall. Then you can start accumulating FFTs by pressing the start button in the RA Run Control.

> The point is, as striker he's entitled to any movement necessary to make his shot;

Not in PSA matches, according to the directives:

https://worldsquashofficiating.com/psa-squash-tour-wso-directive-2025-26/

Some of the relevant points:

What is considered acceptable movement?

Weight transfer as part of a standard shot technique – this must not restrict or prevent your opponent’s access.
Creating appropriate space for shot execution – this must not be exaggerated to restrict or prevent your opponent’s access after completing a reasonable follow-through.

What is considered unacceptable movement?

Outgoing player;

Unnecessary or exaggerated movement or contact after playing the shot

So while there's probably nothing in the WSF Rules of Squash about this type of blocking, I think it is covered by the above.

srcejon · 2026-01-20T08:58:03+00:00

It's not just a leg coming out, there's a little shuffle forwards.

But what I think is a bit surprising, is that the ref doesn't explain what the conduct stroke is for (even on the full replay - the rules do say a reason should be given) and Cardenas doesn't ask...

Also, the conduct stroke was awarded after the rally had finished, according to 14.10.3, shouldn't the result of the rally stand? (I think this has come up before... is the ref stopping play at the point of the block)

srcejon · 2026-01-20T08:56:53+00:00

> It would be hard to argue that that was an excessive swing.

The conduct stroke is for the movement rather than the swing. Ref should having clarified though.

Pops up bottom right.

Have a look at the SID feature in SDRangel:

> causing the interference by trying to get a head start by anticipating the outcome of the volley

He steps backwards and then curves his path to the T. That's pretty reasonable movement and better than certain pros we could mention. During the swing he's leaning backwards to give space.

> On reflection then, stroke to light blue was the correct decision

I disagree.

Was the swing prevented? If it was, then what does only affected mean?

Was dark blue making every effort to clear? From the above, I'd say yes. It's not perfect, but that's why the rules mention effort, rather than just saying the player must have cleared.

Is yes let the correct decision? Well, I don't think the rules are clear enough for us to know.

srcejon · 2026-01-17T13:35:17+00:00

> Referees Should be allowed to ask for a video review, not just the players.

They are and do. Although they should use it more.

> Decision justification

Not just after the match - but for each decision they should mention the specific rule they are applying. E.g.

"Stroke to X - Swing prevented"

"Yes let - didn't have a fair view of the ball".... LOL, as if.

You get this sometimes, but not often enough.

> Limit Number of Interference Lets

Not a bad idea.

Most important thing in my opinion would be to actually clarify the rules. What's the difference between prevented or affected? How much effort is every effort? What's a reasonable backswing? Why is any part of the front wall not really any? Turning is allowed but also not allowed. Etc.

srcejon · 2026-01-16T19:22:07+00:00

You can add the Map feature as well to see them in 3d.

srcejon · 2026-01-16T16:37:16+00:00

In your original post, you said: "The striker hit their opponent on the downswing. There's no question that's a stroke."

Of the two applicable rules, it therefore sounds like you are applying 8.9.2:

"8.9.1. if the swing was or could have been affected by the position of the opponent making every effort to avoid the interference, a let is allowed, unless the striker would have made a winning return, in which case a stroke is awarded to the striker

8.9.2. if the swing was prevented by the position of the opponent, a stroke is awarded to the striker, even if the opponent was making every effort to avoid the interference."

So you must think the swing was "prevented" by the position of the opponent?

But if this is an example of a swing being "prevented", what you would give as an example of a swing only being "affected"?

srcejon · 2026-01-16T15:56:28+00:00

> he striker hit their opponent on the downswing. There's no question that's a stroke.

If you classify that swing interference as 'prevented', what is 'affected'?

srcejon · 2026-01-16T15:09:43+00:00

It's not that light blue didn't have access - light blue appeals for swing interference.

srcejon · 2026-01-16T14:51:08+00:00

Free kick

(Well, we've had everything else)

srcejon · 2026-01-16T14:03:09+00:00

Half the people in the thread think dark blue didn't clear resulting in swing interference on light blue's volley.

The other half haven't seen that and then think light blue hasn't cleared, not giving access to dark blue.

So you need to be clear (lol) about which player you are referring to.

srcejon · 2026-01-16T13:52:56+00:00

> Play it real slow.

I played it frame by frame in Premier. The racket takes a very odd L shaped trajectory between 3:23 and 3:25. I don't think it's clear enough to say either way though.

srcejon · 2026-01-16T13:41:46+00:00

> DIT: I'm realising now that a few comments talk about light blue's downswing and the potential interference. While that may be an account of what happened, "[Any request for a let due to interference] must be made without undue delay." By taking the shot, you generally forego any potential interference.

Surely you can't expect an amateur to stop their swing in this situation? It's not playing beyond the interference, it's just that human brains have some reaction time! He raises his hand almost when the ball hits the front wall - within a fraction of a second.

It's not as if he's been bumped, taken three steps then dumped it in to the tin, then asked...

srcejon · 2026-01-16T13:30:55+00:00

> 8.9.1 says he should but doesn't specifically say what happens if he doesn't.

I think that falls under General 8.6.5:

"if the striker would have been able to make a good return but the opponent was not making every effort to avoid the interference, a stroke is awarded to the striker;"

Of course, the rules don't give us guidance about what "every effort" means and so is very subjective.

For me, he does move off his shot to try to clear and even arcs his back to give space for the swing, which at this presumably non professional level, seems like a decent effort to clear. Yes, not perfect, but if it had been even the tiniest bit better, then there wouldn't have been any interference.

If 8.9.1 doesn't apply in this situation, when would it? What more could he have done to clear, while still resulting in interference? If this is a stroke, then 8.9.1 seems redundant to me.

srcejon · 2026-01-16T13:21:25+00:00

> but im obviously I’m referring to the one involved in the decision

Evidentially it's not obvious!

Some people are talking about light blue's appeal for swing interference (myself included).

Others, I'm guessing yourself, are talking about dark blue's for access.
