NF8M/B Six Meter Beacon

spectrum_tnCurrent status:  up  as of 1905z 24 Mar 2017.  Last downtime was 24 Mar 2017 1810z-1905z.

Note: The beacon is still running at somewhat reduced power (3 watts TPO) due to an ongoing issue with the exciter. This shouldn’t affect receivability of the beacon during band openings too much. I’ll post an update when appropriate. – 28 Oct 2016

The NF8M/B six meter beacon (grid EN82il) operates on 50.0763 MHz running 5 watts into a groundplane vertical at 40 feet AGL. (737 feet AMSL). Because it’s not located at my home QTH, it doesn’t need to be shut down when I want to operate on 6. Note: Although the beacon is on the air more or less continuously, it could go off the air for maintenance at any time, so please do not consider its absence as an indicator of lack of propagation. I will post a notice of planned downtime if possible.

TNX: The NF8M/B beacon was mentioned by Jon Jones, N0JK in Tad Cook’s December 18 , 2015 ARRL K7RA Solar Update. TNX for the FB 599 report and glad to be of service to the 6 meter community. Reports are always appreciated.

If you hear the beacon, please post a spot to your favorite DX cluster or website. In the comment field, please indicate grid squares and propagation type as follows:


For example, if you are in FN20 and copy the beacon via sporadic-E, you’d enter FN20<ES>EN82 in the comment field. (If you use to post spots, it will format this automatically.)
