Marine VHF radio - Wikipedia
Saved by uncleflo on October 12th, 2019.
Marine VHF radio refers to the radio frequency range between 156 and 174 MHz, inclusive. The "VHF" signifies the very high frequency of the range. In the official language of the International Telecommunication Union the band is called the VHF maritime mobile band. In some countries additional channels are used, such as[1] the L and F channels for leisure and fishing vessels in the Nordic countries (at 155.5–155.825 MHz).

DMARC - Wikipedia
Saved by uncleflo on December 23rd, 2018.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email-validation system designed to detect and prevent email spoofing, the use of forged sender addresses often used in phishing and email spam. It is built on top of two existing mechanisms, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). It allows the administrative owner of a domain to publish a policy in their DNS records to specify which mechanism (DKIM, SPF or both) is employed when sending email from that domain; how to check the From: field presented to end users; how the receiver should deal with failures - and a reporting mechanism for actions performed under those policies. A DMARC policy allows a sender's domain to indicate that their emails are protected by SPF and/or DKIM, and tells a receiver what to do if neither of those authentication methods passes – such to reject the message or quarantine it. The policy can also specify how an email receiver can report back to the sender's domain about messages that pass and/or fail.[2]

Equipment Ideas - Albuquerque Transmitter Hunting Homepage
Saved by uncleflo on July 17th, 2014.
As mentioned elsewhere on this site, there is a rumor that transmitter hunting is an expensive aspect of Amateur Radio. This rumor is simply false. Most equipment can be bought surplus, or can be built from scratch, as most of our hunters have done. Below are various examples of equipment that are either commercially produced our the design data can be found on the web. Sometimes the equipment can be obtained at major ARDF events.
