Thanks for this information.
In fact they seem to be very easy to edit with notepad.
It's a shame that various programs didn't agree on a common file format and store them in various places.

Re: Unable to select Bandwidth INPUT sampling rate. Only OUTPUT rate.

No it is the header of *.WAV files that limits the size to 2 Gb not the file system of the hard drive. There is another problem with files recorded by sound cards. The accuracy of the sampling rate. If you make a 24H recording at 8 Khz jumping at the end of it can result in errors of +/- 10 minutes....

Re: SPDPlay Device Controller for Dummies

Hi In fact what you are asking for is hard to do. Soft ware Defined Radios are mainly limited by what you run the software on . On the SDR hardware side basic rules of radio applies: Use an antenna as suited to what you want to receive as possible. Use as little amplification as possible Use as litt...

Re: Mac Users - DO NOT BUY!

That's the main advantage with MACs :
Each time you buy a piece of hardware not supported you have no problems to sell it to somone else :D

Re: SDRPlay lost SDR#-support ?

I hate it when new versions of softwares are actually less useful than the old ones. I should get used to it as each new versions of Windows obliged me to dump quite a lot of good hardware. Instead I stick to old ones and I'm happy that way :D Of course the author of a freeware is free to do what he...

Re: Unable to select Bandwidth INPUT sampling rate. Only OUTPUT rate.

I have been posting my observations and findings in using my SDRplay to work amateur satellites at: https://forums.qrz.com/index.php?threads/sdrplay-as-satellite-downlink-receiver.490793/ Nice topic. I agree that Wide band IQ recordings is the main advantage of SDR's. It allows careful studies of r...

Re: Gap Removal - Best SDR sub $200

I totally agree with this opinion. The gap has never been a big problem for me but as a side effect I noticed that in some cases the new OL frequencies helped to get rid off some surious responses. But I don't like the user's interface : too many interleaved boxes. Keeping everything in the main win...

Re: SDRPlay As Spectrum Analyzer

So if I understand this correctly, I will not be able to measure the level of the signal? In fact as contrary to most receivers in .1 to 1500 Mhz range the AGC can be totally disabled that can be done by using a generator of known level on a frequency close to the signal . Most of the time absolute...

Re: Filter Selection

I can confirm that the LO setting is used to determine which of the RF filters is selected. A 1 Hz resolution is used, so 11.999999 MHz setting will select the 0-12 MHz filter and 12 MHz will select the 12-30 MHz filter. Hi I think the usual way of paralel switching overlapping octave filters is wr...
