@F4EXB - Edouard,
Thanks for the recent post. I have to agree, and I’ve become more appreciative, that the GUI you’ve built SDRAngel on has A LOT of capability to it and I’ve found that it’s very flexible toward other ranges and modes with all the available controls. I’ve also become more accustomed to the multiple demods running and just mute the demod I’m not using and just use the demod that I’m listening to - that is a handy feature. There are a lot of features that at first seemed like ‘too many controls for whats needed’ but as I have used SDRAngel I’ve come to appreciate why they’re there. Many other Hams may not have made this transition so quickly - while I now understand why those controls are there, others may still find the GUI challenging because of their familiarity with other GUIs and how they seem intuitive to use because - let’s face it, and as you’ve described, they all look alike. You’re branching out with a completely different user/GUI approach and I think some have not yet come to realize that different bands have different underlying settings and you’re given the power to the user to make those changes without you, the author, making that decision FOR us…frankly, I appreciate that.
So given all that, I would think if one was to use SDRAngel as the underlying app for a headless radio setup, then the approach would be to setup the receive and transmit with all the possible modulators and demodulators instantiated, tuned, and then available for use and then just ‘select’ them by muting the audio to everything that isn’t used and allow mic and speaker audio to be used from the mod/demod of choice. Is that a reasonable assumption? Please let me know for the purpose of SW architecture of this headless design.
Also, is there any budget for each modulator and demodulator that is instantiated to a target (portable) platform? What is the processor loading if one has all the normal modulators and demodulators (AM, FM, SSB) if just those six (3 modulators, 3 demodulators) are instantiated? Please let me know that, too, as the target for this will likely be the ASUS Tinkerboard (the RPi-clone that runs on the faster processor).
Please let me know your thoughts on this, Edouard, as I’m gathering this info as a means to prepare for that next phase of the development toward a headless SDRAngel design for portable LimeSDR field use.
Again, I appreciate all the hard work that’s gone into this, Edouard - without SDRAngel there would be a flood of LimeSDRs on EBay from all the Hams that would have given up by now - including me. SDRAngel has brought all the excitement back for LimeSDR being used for Amateur Radio HF to SHF.
