@F4EXB - Edouard,
Does that second instance then connect itself to the second Lowband receive path on the LimeSDR (as in RX2_L)? Please let us know how to get the second receiver of the LimeSDR operating, too.
Also - and this is a completely off-the-wall question - but there are Hams I work with that would like to use hardware controls for tuning, mode selection, volume, etc but maintain the base software to work on a ARM or other portable target processors that SDRAngel can compile to. I’m not asking for a new spin of software, but would it be possible to ‘hard wire’ hardware controls (encoders, etc) to be read by SDRAngel such that the overall ‘radio control’ using the LimeSDR is partially HW controlled and ‘hard-wired’ in the code for things such as sample rate, interpolation, decimation, etc that work for HF? Please let me know if it’s possible to - instead of the QT form - to implement code that reads hardware controls and then send that to the appropriate place in the SDRAngel code to make those changes instead of from a GUI. There is interest in making this ARM-based controller such that a spectrum display isn’t necessary for receive or transmit. Let me know your thoughts on that, Edouard if this is a ‘leap of faith’ to implement if we dug into the code ourselves to perform that implementation.
I tried the Win32 Win10 version of SDRAngel this evening when I got home and was not able to see the LimeSDR on my Windows 10 64-Bit machine. But the earlier versions (that are 64-Bit) can see the Lime. I know there are Hams out there what want to use SDRAngel with their LimeSDR on Windows. Right now, I prefer the Linux installation because it appears to react faster than the Win10 version - just trying to help the Win-based Hams out there.
On testing the 3.5.5 on Linux - On my Linux box on Ubuntu 16.04, when I run transmit for the first time on a newly launched window I still get the 6-second delay until I kind of ‘kick-start’ it by adjusting the sampling rate forward and then back to its setting - then it will work perfect and stay that way without the delay. Just letting you know about that bug - it does this to me every time I start a fresh window of SDRAngel.
Also, when I looked at my HP 8530B when the SDRAngel is not transmitting, I can confirm that there is a carrier out there at a lower power level but apparent at the tuned frequency. This is an observation that I think @brendanthebig Brendan or @Axeman Lance may have pointed out already - I’m just confirming that now. When the transmit button is clicked, then it works perfectly and the power level and modulation are apparent.
Okay - that’s my load of info right now. I’m off to go play with SDRAngel again…!
