VK9CZ  -  Propagation

Enter your 6-character Grid Locator in the box below, then click Run for VOACAP charts and detailed propagation
information for your location - thanks to Jari OH6BG/OG6G for this excellent new DXpedition propagation tool.
Note - depending on server loading, internet speeds, etc. it may take up to 20 seconds for the charts to appear.

Eu stations - we live in Scotland, so are fully aware of how difficult it can be to work DXpeditions from NW Europe.  We will make every effort to work NW Eu stations through the pile-up of stronger SE Eu stations.

U.S. stations - we are also very aware of how difficult it is to work NA from VK9C. In 2013 under favourable conditions on the high bands, 22% of our QSOs were with NA, but in March 2016 VK9CK did only 10%. In 2016 propagation was much poorer than in 2013 and it will be even worse in Oct/Nov 2017. We will figure out when we have the opportunities to focus on NA.
