NJ2X Notes:
PSK31 is one of our favorite modes. It is very narrow and works in all kinds of conditions with modest power and antennas. Free amateur radio software like Ham Radio Deluxe have also made it very easy to get started with PSK31.
Phase-shift keying (PSK) is a form of digital modulation that transmits data by changing, or modulating, the phase of a signal.
Terminal Node Controller (TNC) used with computer for PSK communication

NJ2X Notes:
We will share with you a secret that all avid DX'ers already know. Morse Code is an incredibly effective mode for DX (long distance) contacts. You can make contacts with CW in poor conditions and with weak stations that you simply cannot do with any other mode. Operating with CW also gives technician license holders access to the HF bands.
The annual IOTA Contest is here. This is a great opportunity to work DX. The contest starts on 1200UTC Saturday 27th July and runs for 24 hours until 1200UTC Sunday 28th July 2013.
