Group Description

NVIS is not a radio or antenna, it is a technique, and approved for all ages.



However you do not need a ham license or be on amateur, disaster, emergency or military frequencies, all with an interest in NVIS communications are welcome.



NVIS, Near Vertical Incidence Skywave HF radio wave techniques. Perfect for emergencies or to transmit and receive out to a 200 mile radius without a dead skip zone. A hilltop location or beam type antenna is not required. Vehicular operation is possible. We also discuss using low profile, invisible antennas and covert communication techniques.



Picture from http://www.vcars.org/tech/NVIS.html . This a copy of the U.S. Military NVIS antenna AS-2259 which was optimized for 6 MHz and 9 MHz. For Amateur 80M and 40M operation substitute 55.2' and 31', read the messages about this.



Please no attachments (could spread a virus), use only Plain TEXT (.txt or ASCII) for your messages, keeps the bandwidth down. HTML does not work either, so convert it to .txt and send it as TEXT.



Please allow 24 hours, or more, for your membership request to be personally approved or denied, this is to stop SPAM.



"NVIS - Near Vertical Incident Skywave" is the "fake" NVIS group to catch the SPAMers and roBOTS from finding us.



Welcome to the "real" NVIS group.
