Acurite TXR, 5n1, 6045 and possibly others like the new Atlas weather station use parity in addition to checksums for integrity checking.

Currently the parity isn't verified, it's only looked at in verbose mode.

I've noticed I seem to get messages for non-existent devices from time to time. I suspect the message is mangled but the checksum still passes. The parity check in addition to the

I noticed since v0.0.10 release, GNSS-SDR supports Enabled extended coherent integration times. How can I do that? for example, if I am going to use coherent_integration_time_ms=5, besides the following configurations,

Acquisition_1C.coherent_integration_time_ms=5
Acquisition_1C.doppler_step=150

what else should I do?

And how can I configure the non-coherence integration coun

Why is there zero documentation on how to configure after installation? I have a USRP B200 and I suppose there is some place I need to specify that such as in the Settings dialog user device. However, there is no hint as to how to do this. Entering obvious strings like 'b200' or 'USRP' doesn't do it. A couple sentences added to the readme file would go a long way to making this actually do som

I believe the documentation might be incorrect when it states the default value is 8 for the DigitalLevels setting.

I needed to boost my volume, so set it to 11 and it was very loud. I worked my way back on it and ended up with a value of a 3 giving a nice sized boost. Then I looked inside main.cc here and noticed that perhaps line 308 shows a default value of 1?
