Luc,
Long time since we spoke, hoping all is well with you.
Trying rtl-davis again after long while. One note is that I just set up on
new clean P13 Buster install as noticed earlier by you and Steve it fails
to see any Transmitters.
Had read earlier in a sdr forum that this was fixed in a new
This is great I love it!
Wondering if you would consider extending it slightly with 2 additional
tags?
historical_min_avg
historical_max_avg
As mentioned earlier Probably only useful if your database covers many
years.
I have done so on my local copy and like it because I can now produce

We had some rain today and noticed that rtl-davis was reporting very low

looked at databases vales for both my normal production and the development

That sounds OK. Slightly nervous about running a modified weewx-vantage
driver on my production machine, but I guess I will get over my fears:) BTW
both machines run ntp to the same server list , so times are always close
to identical. Also please be aware that on both machines WeeWx logs to
Thanks for explaining it to me. I just did a " grep 'packet missed '" on
the log file and thought I understood:)
Thanks

Had been doing the testing on a laptop which didn't have Weewx installed
on. Today I installed everything on my PI3 development machine. I can't
seem to get humidity to report correctly.This message shows in weex log:

Luc,
Funny story. Actually my ISS is 1 and my wind is 2 as we thought. But they
seem to differ enough in actual transmitter frequency that if I am well
tuned on ISS I can't see wind, however I pick up an unknown neighbor
station of ID:4.
Because of your great advice to listen for tr 2 only I
Hi Rich,
Mine is
RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio
Claimed ppm less than 1. Yours are calmed .5 ppm so there better spec.
However on a less than $25 device I never really trust the claims.
Thanks,
Paul

Kobuki,
A ppm calibration offset would be great! Unfortunately the program does not
provide one as of yet, I am well aware that my Freq list may be of little
use to anyone else. It's just a temporary terrible hack to get some
decoded output for now.
Luc,If I take your current US test Freq
