Greetings –

This note is to announce that the 2014 ARRL Rocky Mountain Division Convention scheduled to be held in Laramie, Wyoming this July has been CANCELLED due to extenuating circumstances. We thank those involved with its planning for the time and effort put forward on behalf of hams across the Division.

We are grateful that the Albuquerque Duke City Hamfest has stepped forward to serve as alternate host of the 2014 ARRL Rocky Mountain Division Convention. It will now take place August 8-10 in sunny Albuquerque, New Mexico. Led by individuals who organized the 2011 Division Convention in Taos, the annual Duke City Hamfest is a standing three day amateur radio convention that occurs in one of Albuquerque’s largest hotels, so it will ably fit the bill as a Division Convention members have become accustomed to.

More details about the 2014 ARRL Rocky Mountain Division Convention in Albuquerque will be provided soon. Please mark your calendars!

73,
Brian Mileshosky N5ZGT
Director, ARRL Rocky Mountain Division

Bottom Line Up Front:

Colorado Section Emergency Coordinator Robert Wareham (N0ESQ) asks that we all keep an eye on Colorado House Bill HB14-1216 titled “Safety Markings For Rural Towers Under 200 Feet”, which has apparently passed the house and is being considered in Senate committee. This bill would affect towers over 50 ft tall in unincorporated areas. N0ESQ is working to make sure that the interests of ham operators are taken into consideration and hopefully will be able to use this bill to get a PRB-1 section added.
What is PRB-1? It is a limited directive from the FCC to local governments to give some extra consideration to zone/code limits for things like antennas because of the many services ham operators provide, especially during emergencies. PRB-1 itself does not require that local governments permit a 50 ft antenna, just that they give it extra consideration. There is a lot of legal stuff that goes along with PRB-1 regarding precedence of various courts, etc., but getting a statewide PRB-1 type of legislation would be a positive move.
(BTW, I have searched around to find out what PRB stands for and I am told that this directive happened to be put out by what was then known as the Personal Radio Branch of the FCC, making this probably the first directive put out by this branch)
Again, keep an eye out for HB14-1216 and watch/listen for emails and radio announcements in case we need to engage in a letter writing, call-in campaign. A link to the bill is:

Youth in Amateur Radio

The August issue of WorldRadio Magazine has a great article featuring Carole Perry’s (WB2MGP) Youth in Amateur Radio Forum this year at the Dayton HAMvention. This was Carole’s 25th year of presenting the Youth Forum and for that I congratulate her. Once again, one of the Youth Forum presenter’s was from the BARC Juniors (Boulder Amateur Radio Club). Gary Bailey, KDØTRO, age 10 was the youngest speaker at the Forum and he WOW’d them with his presentation on “Radio’s and Components I have built and tested”. See the link below on this year’s Youth Forum and the talented young hams.

In case you were wondering….

The Boulder A-Index Explained:

The geomagnetic A-index is derived from the K-index, which quantifies disturbances in the horizontal component of earth’s magnetic field, using a 0-9 integer scale.  K and A indices are indicators of ionospheric radio propagation conditions.

A value of 1 on the K-index indicates calm and 5 or more indicates a geomagnetic storm.  The K-index is derived from the maximum fluctuations of horizontal components observed on a magnetometer, during a three-hour interval.

The A-index provides an average level for geomagnetic activity.  Because K scale magnetometer fluctuations are non-linear, quasi-logarithmic, it is not meaningful to take averages for a set of K-indices.  Instead, each K is converted back into a linear scale called the equivalent three hourly range “a”-index (lower case “a”).  The daily A-index is an average of eight “a”-indices.

For many years, local hams had access to an A-index published for Boulder, Colorado.  Although the formal “Boulder A-Index” is no longer officially published, the magnetometer used to provide it is still operational.  Below, are web links to current Boulder A-index data.

AN EXCELLENT HOMEBREW BOOK

There is an excellent book called “From Crystal Sets to Sideband” written by long time Boulder Amateur Radio Club member, Frank Harris, KØIYE in 2002 and last updated in 2011. It’s a wonderful work of more than 400 pages starting with basic electricity working all the way up to design considerations for homebrew sideband rigs and beyond. Full of great photos, diagrams and humorous cartoons, it’s an entertaining read as well as a great reference sourcebook…and it’s FREE! KØIYE graciously and generously donated it to the public. Thanks to Four State QRP and QRPARCI it’s available to be downloaded and printed freely at http://www.wa0itp.com/crystalsetsssb.html 

A very nice write up about the author, Frank, KØIYE appeared in this World Radio Magazine Article in May 2011
