- KC0KJF Doble Bazooka
- The Double Bazooka Dipole is a very efficient single band antenna which is very quite,and does not
require the use of a balun. This antenna consists of coax (RG58) with the shield split at the center and the feedline attached to the open ends.

- 20m Half-Wave End Fed
- A Half wave antenna has a high impedance feed point. This can be matched using a 1/4 wave stub matching section and converts the 40m vertical into an L-shaped 20m J-Pole antenna. The 300 ohm feeder used for this purpose must be kept away from the ground.

- VHF Yagi from Old TV Antenna
- 6m/2m/70cm Yagi Antenna Built from Old TV Antenna
This turned out to be a great little antenna. It works the 6 meter, 2 meter and 70 centimeter bands. You can use one common feedpoint or two seperate feedpoints depending on how you would like to connect this antenna to your transceiver.

- The W3EDP Antenna
- A wire antenna feeded with an unsymmetrical feed and a 1:4 balun can be tuned from 6 to 80 meters band but can be noisier than a dipole and cause RF in the shack

- Ham Call Lookup - Windows Phone
- Ham Call Lookup is an windows phone app that allows you to perform amateur radio callsign lookups via QRZ.COM. It also incorporates DX cluster feeds, DXCC information retrieval and Solar data all within one application on your Windows Phone. For callsign lookups, the application uses the QRZ.COM XML interface, please register at QRZ.COM for an account if you do not already have one. The application will happily work with a free QRZ.COM account although it is recommended to use a paid account, as a minimum the XML Logbook Data paid option, in order to access the full functionality of callsign lookups within the application.
