fix(profiler): avoid 100% CPU usage when missing certs

1

The previous implementation relied on .createProfile() sleeping a bit, which in turn relies on gax.Invoke's retry behavior and the initial backoff in the retryer used. This works most times, except...

Implement server side of rigctl protocol

3

I'd like to be able to use fldigi or wsjt-x with my SDR. These programs support hamlib, and I can get them to control the SoftRock directly (set frequency, tx/rx,...

GNU Radio code can block reactor

9

As noticed here: https://github.com/kpreid/shinysdr/pull/82#issuecomment-306489971 Demodulators are instantiated within the reactor thread. Since demodulators are also GNU Radio blocks, this involves calling GNU Radio code which isn't designed with Twisted's event...

UI notes

I've been thinking I should keep a log of UI things that have confused or surprised me. No particular action required, just things to consider. - Sometimes I try to...

Demodulators aren't notified of any events

For the WSPR demodulator (#82) I have use cases for three kinds of events: - The receiver was deactivated due to being out of range, so it can stop invoking...

IQ balance correction

Using a SoftRock receiver I get some pretty bad signal mirrors:  There's a blind optimizer available: http://cgit.osmocom.org/gr-iqbal/ In my experience it works pretty well, however it takes a little...

Aliasing in waterfall can hide stations

2

If the waterfall resolution is high, and there's a narrow-band signal (like CW), then the fine tuning of the receiver can cause stations to disappear. Here's how I reproduce it:...

Work is my own, done with FreeCAD, based on the mechanical drawing at http://suddendocs.samtec.com/prints/sma-j-p-x-st-em1-mkt.pdf Some of the dimensions aren't specified in the drawing so I guessed. I don't have this...
