The globe, each with their own ID and each submitting daily data to Stanford. The SuperSID Project has several of these “receivers” all around The beauty of the SuperSID soundcard setup is that several stations canīe monitored at once, rather than just one as with the Gyrators (or any The files to Stanford at the close of the day.
Simple vlf receiver circuit software#
Special software that monitors VLF frequencies, records data once everyĥ seconds, 24 hours/day, then automatically sends They provide a “receiver” (actually a low-noise pre-amp) to be Run by Stanford University and SARA (Society of Amateur Radio Astronomers). Lately we have become involved with a project called SuperSID which is The output of these Gyrators is fed through an analog to digital converterīelow are photos of our versions of the Gyrator II on the left and Gyrator

Tuned with 365 pf tuning condensers like you would find in an old AM radio. Loop antennas are roughly 20” square with about 140 turns of #30 wire The designs for which can be found online (“Gyrator II” and “GyratorįAR Circuits has boards for them and the parts are easily obtainable. The Gyrators are inexpensive, very simple, easy to build, VLF receivers We did this with homemade “Gyrator” radios and homemade loop

VLF stations in order to track SID’s (Sudden Ionospheric Disturbances). Recently got involved with monitoring US Naval submarine communications Place where you guys stole the McMath scope from?) A few of us at McMath-Hulbert Solar Observatory (you remember, that old
