VO1NA from Newfoundland with 10uW must hold the record for the longest running VLF transmission! Coming in well the last couple of days - http://78.46.38.217/fbins3.html#p=1536487200&b=280&s=sp&m=car
I've not been mucking with the tx or tuning so perhaps Mother Nature has provided an ERP improvement -- the wx has been quite dry recently. Thank-you for the report and the spectrogram service. It ke
Currently testing an active antenna for a research application. Just 80cm long. It picks up VO1NA just as well as my regular E-field receiver. A very useful beacon Joe, thanks a lot! -- Paul Nicholso
Hello Paul, Commercial or home brew? Will you be able and willing to post details of it at some point? Thanks. -- Best regards, Chris mailto:[email protected]
Hello Markus and Paul, group, That's a much better explaination than Doppler shift. What would cause a 180 degree phase shift? Is there an XOR gate in the sky. A few more dB will depend on getting so
Hello Joe, Fine signal! "What would cause a 180 degree phase shift? Is there an XOR gate in the sky?" Might we say "D" Flip Flop (comparatively slow rise/fall). Attached is roughly how the effective
Hi Jim, Markus and group, Thanks for your explanations and Jim's effective height plot. This was used to estimate the interval (07-22ut) for which the phase was inverted. Between 17 and 24 September,
