Time to brush up your education?

PROBLEM: You’re trying to remember how to calculate the great-circle distance between you and W1AW using polar coordinates…  …but it’s been a few [or perhaps a few too many] years since you last sat in on a math class.

Like many, my hectic schedule leaves me with little time to deal with my ‘honey do’ list, let alone keep my educational skills refreshed/updated.  How many of us hams have procrastinated over the years that we don’t have the time or money to go back to school / correspondence; and yet, we all recognize that education is a lifelong pursuit.  What to do?

Allow me to share something – it’s called the Khan Academy.  [link opens in new window]

The Khan Academy is a non-profit organization, with the sole intent of changing education for the better by providing a world-class education to anyone, anywhere…

…honestly, it’s as simple as watching a video clip…  …but the best part…

 …it’s completely FREE! (donations appreciated)

So what does the Khan Academy offer?  Have a peek here.  [link opens in new window]

Having a difficult time with a particular lesson or teaching point?  No problem – the Khan Academy’s structured lesson plans ensure students won’t be pushed into the next level (read ‘more difficult’ material) until they’ve mastered the current material.  In a nutshell, unlike the traditional classroom, every student can learn at their own pace!  And if you’re really having a problem getting your head wrapped around something, simply ask one of the hundreds of online volunteer coaches for assistance!

Watch Salman Khan discuss the Academy here.  [link opens in new window]

Happy learning!

MRARC’s 2m Repeater is on the move!

On 1 May 2012, during our monthly business meeting, the MRARC membership overwhelmingly approved project funding towards building a new repeater, at a new secure site, atop Thornhill (aka Grant Hill).

A tremendous amount of work has been quietly going on behind the scenes over the last couple of months by members of our Repeater Committee:

- A brand-new Kenwood TKR-750 repeater system and antenna system have been generously donated to our organization.

 

- Approval to use the new site has been secured. Our new site is located 7.27km (4.52mi) ESE of the current repeater location, and provides some 290m (952ft) in additional elevation.

 

- Installation of our new antenna on the tower at the new site has been arranged (the funding for which was also generously donated).

 

In addition:

– Burn-in, bench testing, and calibration of the new repeater system is currently underway.
– A new controller, linking system and cavity are now being sourced.
– Discussions with the British Columbia Amateur Radio Coordination Council (BCARCC) and other groups are being undertaken at this time.

Our current 2m repeater system will continue operating in situ until the new repeater system/site is fully operational; then powered down and maintained as a cold backup at it’s current location. While our current repeater site has sufficient coverage of the immediate Maple Ridge / Pitt Meadows area; it’s EIRP footprint throughout the region has been somewhat spotty at best, with numerous holes and barely readable beyond Bellingham to the South, Sumas Mountain to the East, and Nanaimo to the West (the Longley-Rice coverage diagrams below are generous, with the 90 percentile diagram closest to actual). The majority of our coverage problems can be tied to our current repeater location (and multipath related to adjacent structures in the immediate area).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Once antenna installation is complete at the new site, our new repeater system will be installed, configured, linked and tested. Phone-patch, IRLP and Echolink will then be migrated over to the new repeater and tested.

Projected coverage gains for our new repeater system/site should be significant towards the NW, W, and SW; with moderate gains to the E and S (once again, the Longley-Rice coverage diagrams below should help illustrate).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

MRARC members are now eagerly anticipating the new repeater system and site, which should provide continuous 2m coverage throughout the entire Lower Mainland – from Chilliwack to West Vancouver; and with a clear shot to PEP in both Surrey and Victoria, assisting both our organization and membership towards better fulfilling our EMCOMM commitments.

Our membership wishes to recognize the many hours of hard work that have already gone into this project by members of the Repeater Committee; with special thanks going out to: Nick [VE7TE], Graham [VE7WGJ], Earl [VE7QJ], Marty [VE7XX], and Eric [VA7EW]

QSX, more to follow….

MRARC Proudly Announces….

On the 5th of April, 2011, during our monthly business meeting, the membership of the Maple Ridge Amateur Radio Club (MRARC) unanimously adopted a resolution, calling for the twinning of and a bilateral cooperation agreement between the Ipswich & District Radio Club (IDRC), located in South-Eastern Queensland, Australia, and ourselves.

Originally proposed during a conversation between Warren Heaton [VK4GT] and MRARC Vice President, Mike Stenner [VA7BZ]; the matter was further broached with IDRC President, Michael Charteris [VK4QS], during Mike’s visit down to Australia in March.

An agreement in principle was reached between Michael and Mike  on the 19th of March, during a barbeque event at the IDRC clubhouse; where it was mutually agreed that this proposal should be tabled within our organizations, for discussion and ratification by our respective memberships.

MRARC proudly acknowledges this historic event as it’s first bilateral agreement with another organization; wherein MRARC will henceforth recognize IDRC as a sibling organization and the IDRC membership as our brethren, with shared purpose and common values.

Both organizations have agreed to the free exchange of information and cooperation on matters of common interest, including [but not limited to]:

- the shared exchange of social, cultural, and traditional friendship, such that both organizations will openly welcome and recognize each other’s membership as our own, with diplomatic privilege accorded any visiting member while in-country;

- joint cooperation on matters of regulatory, technical, and operational importance, such that both organizations will recognize our common challenges and aspirations; and jointly welcome the opportunity to share in the learned knowledge and advice of our brethren;

- the fostering of bilateral communication and participation within each other’s activities, such that both organizations would mutually benefit from these shared discussions and experiences; and

- the open exchange of ideas and proposals, towards how we collectively, as organizations and individuals, can further both Amateur Radio and our local communities.

This twinning of these clubs within Ipswich and Maple Ridge is somewhat ideal, given our many common traits:

-the City of Ipswich is located approximately 40 minutes drive outside of the third largest city in Australia - Brisbane.  Similarly, the District of Maple Ridge and City of Pitt Meadows are located some 40 minutes outside of the third largest city in Canada - Vancouver.

-both communities are built alongside a major river system

-both communities are within close proximity to the Pacific Ocean.

-both countries share a common lineage and language

-both countries rank among the least populated places on the planet, relative their size; with only 3.4 people per sq km in Canada & 3 people per sq km in Australia - ranked 229th and 234th respectively.

-both organizations are of nearly identical size and demographic

- both organizations are attempting to instill both knowledge and interest in Amateur Radio within our youth.

-both organizations are of nearly identical age: IDRC being founded in 1962; and MRARC being founded in 1964

L to R: IDRC President, Michael Charteris [VK4QS]; Lord Mayor of the City of Ipswich, Mr. Paul Pisasale; and MRARC Vice President, Mike Stenner [VA7BZ]

Mike Stenner [VA7BZ], as ambasador, accepting a Challenge Coin gift Michael Charteris [VK4QS] on 19 March 2011 - a gift from the Ipswich & District Radio Club to the Maple Ridge Amateur Radio Club

During the MRARC business meeting on 5 April 2011, Mike Stenner [VA7BZ] presented MRARC President, Lynn Wold [VE7LYN] with the Challenge Coin from IDRC.

Both sides of the beautifully crafted Challenge Coin presented from IDRC to MRARC; this limited production of coins was commissioned by IDRC as part of last years recognition of the Wireless Institute of Australia’s Centenary
