144 MHz or 2 metres is probably the most popular amateur band for local or semi-local contacts.
However, tomorrow it will be full of low power or QRP stations trying to make contacts far and wide in the annual Practical Wireless 2m QRP contest.
All modes from FM to SSB and CW are allowed and it’s a great opportunity to snag some new squares or work some hilltoppers. All you have to remember is that no more than 3w is allowed as your output power.
This is a great chance to get out onto some high spots for an hour or so too and see how many stations can be worked.
So if you are at a loose end tomorrow, why not take part? Even a small antenna such as a tiny yagi or halo for horizontal polarisation will work. The usual antenna types for vertical polarisation will also give good results.
See http://www.pwcontest.org.uk/144MHzrules.html for more details and remember, have fun with RF!
