Is it possible to decode an ebnaut transmission using only the sample rate correction using external VLF transmitters in Spectrum Lab? VY 73 Jacek / SQ5BPF
Hi Jacek, Yes but then the transmitter must be available during the whole transmission time and a single soundcard glitch can cost you to decode, so it is a high risk to use that method. I would prin
I'm not sure. Maybe the frequency accuracy will be enough. But there will be no timestamping so the user will have to search for the time offset. Maybe not a problem when using long symbols. Sounds
Many cheap GPS modules have an awful lot of jitter, not being designed for accurate 1PPS timing applications. I tried several with SpecLab and was not happy with the jitter performance. I have not tr

Hi Jacek, short answer: Yes (if you have a soundcard without dropouts on the input). It will work on many modern PC's. For example, RN3AUS has achieved successful decodesd from DK7FC using samplerat
Hi Jacek, Yes, he picked up my signal with the help of GBZ one one of his two PCs. However the next thing is that GBZ of whatever reference must be available all the time, of course. Alex' spectrogra
I have a uBlox UP501 it's not good but not as bad as some for jitter. it works very well with vlfrx-tools (haven't looked at the code, but probably Paul included some magic code to average out jitter
