And the video of KA4UDX’s contact with PJ7E – Sint Maarten on 15 Meters Band
* A special note: Normally on SSB/HF radio we operate simplex – transmitting and receiving on the same exact frequency. In this case PJ7E was transmitting on one frequency and listening on another frequency slightly higher up the band. An operator that’s paying attention would hear that he was saying “350” – pay close attention when you listen to the video and you will hear him saying that. So I used my dual A/B VFO capability and dialed in that frequency and went into “Split” mode to listen on his TX and transmit on his RX frequency. This is kind of like Half-Duplex. You can’t really listen while you are transmitting but you are in a duplex mode with split (2 independent) frequencies. You can do other things as well such as use independant RIT and XIT – Receiver Incremental Tuning and Transmitter Incremental Tuning to do similar things. U.S. Stations will often use XIT to go slightly “off frequency” to catch the attention of the DX station. You can also use a sort of “Social Engineering” by timing your transmit to “miss” the pack of all the other stations calling – or say something special that might be heard in his or her headphones to set you apart from the MANY other stations that are calling them.
It’s a game. It’s a sport. And you are there to win. Be polite but win. You want them to hear you … you want to get the contact in your log. (As a valid contact.)
