QRP ARCI HF Grid Square Sprint
QRP ARCI Contest Manager - Jeff VA3JFFThis short CW sprint runs from 1500Z to 1800Z on Saturday March 13th 2010.

This contest is now in its' fourth year and is proving very popular. If you operate in the event please send in an entry to show support. All entries must be in by 13th April 2010.



Unsure about Grid Squares ?

Maidenhead Grid Square map of North and South AmericaDon't worry - it's just a way of locating your position on the planet using a 6 character code. They have been used for years by VHF/UHF DXers, now grid locators are being exchanged on the HF bands too. For our purposes we will be exchanging just the first 4 characters (e.g. FN02). In the USA this equates to a roughly rectangular area 70 miles by 100 miles. Steve Ford WB8IMY wrote an excellent article explaining locators in the April 1994 issue of QST. There is also a good explanation on Wikipedia.

If you know your latitude and longitude then you can easily work out your grid square using either the ARRL or AMSAT calculators.

www.voacap.comHere's the easiest way of all - there's a really great propagation prediction program called VOACAP. Go to their QTH Locator web page, it shows Scandinavia by default. Drag the map over to your location and zoom right in. You will find your latitude, longitude and grid locator displayed on the right hand side of the page. Great stuff !

Any questions should be directed to the QRP ARCI Contest Manager Jeff Hetherington VA3JFF (pictured above).

Solar Activity & HF Propagation
Propagation is a fascinating subject. It affects us all, is discussed at length on QRP-L, but is understood by few ! Just what does that Storm graphic mean ? That's bad isn't it ? Er, or is it good ? What about that K-index - or should we use the A-index ? Just what do those numbers mean anyway ?

Paul Harden NA5N is one of those rare individuals who really understands his subject and has a talent for explaining in a way we can all understand. He's also a whizz at presentation. This feature is set to become a classic, full of hints and tips - you will become your local club's propagation guru !
