Re: Resampling
Hi Steve, I noticed the reversed StreamInit/Decimate function calls, but thought it might actually be correct. Once you call StreamInit, it's off to the races - the API immediately starts sending samples, probably with decimation = 1. Can you really change the decimation at this point ? This is anot...

Re: Resampling
Hi Steve, Thanks for the code - that is a huge help. A few questions/comments for you and/or the SDRPlay team: - When in the LowIF mode, why can't the decimation be user specified ? The man page says: "Also for IQ output in Low IF mode, enable must = 0 as the decimation is automatic within the API."...

Resampling
I have an application that needs I/Q data at 192 kHz. The lowest that the RSP's go is 500 kHz. I don't need any FFT or demodulation - I just need 192 kHz I/Q. Resampling ? Suggestions on how to do this in software ?
Thanks,
Steve

Question for Heinrich, DanubeBCL
Sorry to waste the bandwidth here, but I haven't found another way to contact DanubeBCL. I am working on a bridge between HDSDR and CW Skimmer. Specifically, I would like a change in the HDSDR LO frequency to cause a change in the CW Skimmer LO frequency. Will one of the existing HDSDR DDE mechanism...

Problem with current RSP1 ExtIO and API
I am the software developer for a popular ham radio program called Waterfall Bandmap. I recently installed the current RSP1 ExtIO and API on Windows 7. I am seeing a problem if I initially select the RSP1 ExtIO (but don't call StartHW), then select a different (non-RSP) ExtIO, then reselect the RSP1...

Re: RSP2 front-end protection?
Hi Ian,
I'm sure you know that the TS-590SG has an RX-output (shared with the low power DRV output). I have been using the RSP1 since June with the TS-590SG RX-output. I run 1500 watts, with monobanders, high duty-cycle, in contests. No problems with the RSP1.

Re: HDSDR 2.75 is final now
Let's hope we don't have to wait another 3+ years for the next release.
Looking forward to the open source that was promised for HDSDR.

Re: New ExtIO for RSP1
The EXTIO plugins search for available devices and use the first one available. That seems a little non-deterministic when you have multiple RSP's, since "first" depends on which one is first seen by the OS on the USB bus when booting the computer. I would like to see an extension the ExtIO to be m...
