I was just talking to Mole about MFJ's beacon locator ($119) the other day, then I stumbled across the same thing (as far as I can tell) for FREE on the Android Market.  https://market.android.com/details?id=com.wolphi.clock&hl=en


Going to their website, I found that they offer this as a free download for tablets, Iphones, Windows & Mac computers, etc...  Available here ---> NCDXF/IARU International Beacon Project - Tools for Listeners


If you're not familiar with these beacon maps, they're pretty simple.  There are 18 NCDXF/IARU Beacon Locations across the global map.  Each sends a 10 second CW broadcast on four different frequencies (10, 12, 15 & 20m) with it's call sign and three different tones at different wattages (50w/10w/100MW?).  You simply tune in to the broad cast frequency (shown on the map) and listen for the beacons on your radio.  When you hear the signal, you can look at the map to see which beacon is broadcasting.  They move across the map from East to West and the whole cycle (worldwide) takes three minutes to complete.


Pretty cool software to check propagation in conjunction with your station.
