Missouri Radio Amateur Petitions FCC to Designate “Symbol Communication” Subbands

James E. Whedbee, N0ECN, of Gladstone, Missouri, has petitioned the FCC to designate Morse (radiotelegraphy) Amateur Radio band segments as “symbol communication” subbands. The FCC has invited comments on his Petition for Rule Making (RM-11769), filed on May 2. Arguing that retaining the current regime of “legacy” CW subbands has proven to be grossly inefficient, Whedbee said he’d like to see the FCC delete all privilege restrictions that limit any part of the Amateur Radio spectrum to Morse code to the exclusion of other modes.

“Nostalgia for retention of Morse code telegraphy-only subbands is also an insufficient reason to avoid moving forward to [the] elimination of such subbands, because nothing about this Petition suggests the elimination of the mode itself, only that it not be the sole authorized mode in the subject subbands,” Whedbee told the FCC.

HOW LOW CAN YOU GO?

The online Blog HACKADAY.com published an article by Dan Maloney talking about “THE WORLD OF QRP OPERATION.”

Newly minted hams like me generally find themselves asking, “What now?” after getting their tickets. Amateur radio has a lot of different sub-disciplines, ranging from volunteering for public service gigs to contesting, the closest thing the hobby has to a full-contact sport. But as I explore my options in the world of ham radio, I keep coming back to the one discipline that seems like the purest technical expression of the art and science of radio communication – low-power operation, or what’s known to hams as QRP. With QRP you can literally talk with someone across the planet on less power than it takes to run a night-light using a radio you built in an Altoids tin. Now that’s a challenge I can sink my teeth into.

New repeater: 146.970- PL:100

TRYON ARC is honor to announce our new repeater 146.970 with negative offset and PL: 100Hz. The repeater is located in Fultonville, NY.

The club would like to thank everyone who helped getting this repeater up specially Rocco (WU2M) for fixing and configuring the repeater and Jim (KC2JJQ) for providing the location for this repeater.

Please program and use this repeater. We are looking for reports. We are trying to get an idea of the coverage of the repeater.


Near-Real-Time F2-Layer Critical Frequency Map

Ray (NM2O) has provided a link to the “Near-Real-Time F2-Layer Critical Frequency Map” website. The website shows the Critical Frequency. This information supplements the band conditions, flux, K, etc. graph to the left.

The definition of Critical Frequency is: The highest frequency that is returned when a signal is sent straight up. To work in close on HF, you need to be below the critical frequency.

The Space Weather site generates a new plot every 10 minutes or so. The plot takes into account the solar flux, the K index, the time of day and the date.
