VLF, Since 22:45 UTC i'm running a plain and stable carrier on 8270.00500 Hz. The antenna current is 410 mA, in the moment. It is a test of the new coil. The coil is built to manage 700 mA. Maybe i j
...sorry, it is on 8270.0025 Hz. A signal peak is already visible on the DF6NM grabber: http://www.df6nm.darc.de/vlf/vlfgrabber.htm 73, Stefan Am 15.01.2017 23:56, schrieb DK7FC: VLF, Since 22:45 UTC
Hi all, ...running 700 mA again since 18:50 UTC. I am testing my new PVC coil housing. It protects the coil from rain and sunlight. Fortunately it is already proved that there are no dielectrical dis
VLF, There is a trace very close to 8270.005 Hz on the 47 uHz spectrogramm of the RC4HAA VLF grabber, http://136.su/grabber/ This is a land path distance of 2877 km, http://no.nonsense.ee/qth/map.htm
Hello Alex, Thank you for the capture! About 15 dB in 47 uHz, so we still can transfer EbNaut messages, 5 characters should be no problem :-) I would like to test it again but there are really many t
Hi VLF, Once again a plain carrier is now running since 19:30 UTC on 8270.005 Hz. I am not on the maximum level of the coil, just running 600 mA for this night. I need to make some improvements on th
Hi Markus, Are you monitoring from 4X? Is this maybe the actual reason why you ask for a daytime carrier? :-) Well i started this 300 char transmission now. It could be a bit to optimistic to assume
A great big signal here, 0.30 fT http://abelian.org/vlf/fbins.shtml#p=1509778800&b=120&s=fd In 34.7 uHz (22:00 to 06:00): H-field: 26.66 dB 93.1 deg E-field: 24.99 dB 96.0 deg Combined: 31.70 dB. Poi
Hi Stefan, unfortunately I will be here only for a few days, and won't have the opportunity to rig up any kind of useful VLF RX-antenna. The DL0AO grabber is online again. Interestingly, this time be
Paul, many thanks for the feedback. Amazing! It never gets boring. 73, Stefan Am 04.11.2017 10:35, schrieb Paul Nicholson: A great big signal here, 0.30 fT http://abelian.org/vlf/fbins.shtml#p=150977
