Lower Potomac Marathon Support Needed

Featured

The club has been supporting the Lower Potomac River Marathon for many years
now and it’s time to start putting together a support team.

http://www.cbrcmd.org/lpr_marathon_2015.htm

The date is Sunday, March 8th, 2015.  Race start time is 07:15 AM (Show up
at 6:30AM).  Keep in mind this is the start of Daylight Savings Time, so
you’ll lose an hours sleep the night before.  The course stays open until
13:00 (but we’re usually done around noon-ish).

The start/finish is the Paul Hall center in Piney Point
(http://www.seafarers.org/paulhallcenter/phc.asp)

We are looking for 12+ volunteers (and you can work a partial day if you want).
At the end of the marathon you’ll get a nice T-shirt and a buffet-style
lunch is served

Please email Tom Shelton (ND3N) at (gl1800winger@verizon.net ) with your call, name, availability, and t-shirt size.

Southern Maryland QRP Challenge

Featured

The St. Mary’s County Amateur Radio Association is proud to sponsor the Southern Maryland QRP Challenge. The challenge will start 0000 UTC on 1 Feb. 2015 and will end 2359 UTC on 28 Feb 2015. This is a two part challenge:

Challenge 1: Miles Per Watt (MPW) Challenge

This category will be judged completely on miles archived per watt. With a Maximim of 10 Watts being used! Power output should be determined be you rigs power setting if it has a read out, or by adjust your power output on AM before switching to SSB or CW. To calculate Miles Per Watt (MPW), look up the callsign you have contacted on QRZ.com, click on the Details tab, and scroll a little over half way down the details page looking for Distance. Use that distance shown, and divide that number by the amount of watts used for that contact, giving you your MPW. The calculations will be verified just to check our math.

Challenge 2: Points Challenge

This challenge will be based on point values per contact. See below for points breakdown. Track you contacts and points and submit your totals each Saturday in February starting with the 7th. By submitting contacts each week, this will give others a goal to shoot for and some weekly bragging rights!

Antenna Build Off Proposal

Joe Moraski (KY3F) spent a portion of him career at the base range testing antennas. He was the individual who proposed this build off and pointed me in the direction of how we should go about testing those antennas that we build. Tom Shelton (ND3N) took the idea and ran with it putting together a proposed set of categories and rules. We will be meeting at the Base Museum Saturday January 17th @ 10am to discuss and finalize the details for the contest. Attached to this article are the proposed rules and proposed test procedures.

Antenna Handbook Section 27 (Focus on section 27.8)
SMCARA Antenna Challenge (Proposed Rules)

See you Saturday.
