Next time you call CQ and get no reply, try announcing your presence on the QRP Spots website.
Tell other QRPers that you are on the air and looking for contacts. Of course you can use the QRP Spots website from the shack, but there are other options for /P portable stations and backpackers. Post your message via Twitter or, to keep things entirely ham related send an APRS message from a compatible handheld.
