Alright, another bit of info which might be useful. Back a couple of years ago when analyzing the Davis packet structure, coding, FSK parameters, etc., I did a very simple test in SDR#. I set it on the center of the EU band, zoomed around +-500 kHz into view and observed the small sausages originating from the transmitters around the house. They were all over the place until I learned to correct the offset of my SDR stick (since then I purchased a 1ppm one). After I found applied the proper offset of my stick (used Kalibrate, but there are better tools now), the spots started to appear within about 5 kHz of their expected frequencies (I'm fine with that precision, it's a cheap stick, not a calibrated VNA). I calculated the frequencies from the Davis Arduino code table. For me it alone confirms that the frequencies are right and well known. Thus they can be used for rtldavis, too, as is. For anyone in the mood, I suggest trying this simple method out to re-verify the frequencies.
Of course I'm eager to try your code as well, soon.
