Ha ha ha. Its a test. If every one put LF in their subject line my filing of mails would be perfect. It won't work for some reason when using just the address. use the mail headers for filtering. i
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
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
Decoded fine the 20170226 transmission (text send offline to Stefan). the Eb/N0 is small probably because of some problems with the receiver (it says that 9984s, or almost 3h were padded), probably b

would it be possible to use the phase shift from a strong VLF signal to compensate the phase shift for an amateur VLF transmitter? for longer transmissions (when the ionosphere height changes etc) ov
But I do find that Windows10 is not quite kosher regarding continuous operation. I'm running the slow VLF stuff on a convertible laptop under Win10 Home. Within a week or so after a restart, memory u

I'm already dancing on another party, the transmitter is running 'key-dwon' since almost a week now. On the weekend there will be a rain period but i want to risk to continue with the transmission,
