I/Q recorder utility

[Victor]

Hi

I’m using the I/Q recorder utility in Spike.
When opening the utility the default “Max File Size” is always set to default value of 140000 kb. Is there a way to save a pre-set or similar so every time I open the recorder it is set to what I have saved?

Hi Victor,

There is not any way to do this right now, I will see about improving this for the next release.

Thank you 🙂

This functionality was added and will be in the next release of Spike.

Hi

Is there a possibility to implement this to the the iq recorder, that the Center frequency and sample rate Is saved to the file name?

Thank you

[Andrew]

Thank you for the feature request Victor. I will update this thread if we add something to address this.

Hi Folks,
Im using the I/Q recorder utility for satellite downlink receptions – the SNRs are often just above the noise floor….

The Preview spectrum one sees whilst setting up/making the I/Q recording is very basic – and it can be hard to distinguish if the target signal is present or whether one is simply looking at noise.

I believe ADDING a new option for AVERAGING to this preview spectrum would be a great help in this regard. Ideally with user selectable values e.g. 4 or 8 ……

Hope this might be possible

Also I would like to “upvote” the idea of having the centre freq and sample rate at which a recording is made, included into the auto-filename.

Many times Ive found myself unsure of what S.R. was used – “just a few minutes later”…..

It would be great if we didnt need to make a note of it – and it was just captured and put in the filename as a standard.

Many thanks
Alan

Thanks for the feedback Alan. I’ll get this into our request log. I think these are reasonable requests.

Hi

Thank you for the update, with cf and sr included I have been looking forward to this a long time it will simplify my work a lot.

Sorry but I have another request regarding this. Is it possible to implement to get more frequency accuracy? So that we can have at least kHz accuracy, the complete frequency that is printed in the “Center Freq” box.

Also regarding the sample rate, it’s rounded of to 2 decimals, is it possible to get the full correct sample rate, for example the printed sr is: 1,56Msps and the real is 1,5625Msps?

Thank you and best regards

Thank you for the follow up feedback Victor.

I will see about making these changes, but can’t guarantee when they will be available.
