![]() Your mileage will vary.īut the real rub? When activating a site, you are the DX. With this said, some transceivers are better at CW decoding than others. They’re better at handling a rag-chew with a friend rather than the dynamic environment of multiple CW ops calling a site activation. In other words, transceiver decoders are simple and typically are looking for standard, electronically-keyed code that’s properly tuned-in. and depending on the operator’s skill, straight keys, semi-automatic keys, and side-swipers (or “cooties”) can also confuse them.However, transceiver decoders (at present) will get confused by: If your transceiver likes the code speed and if you’re properly tuned in, you could get a very good read of the code being sent to you. That doesn’t always happen, of course.Īlso, most transceivers will only interpret code that is completely tuned in properly–many have CWT and auto tuning functionality to center the frequency on the received signal. Some struggle with code that varies in speed–for example, it might expect received code at the same speed your keyer is set to. Transceivers decoders are typically pretty basic and not terribly adaptive. I’ve reviewed numerous transceivers with built-in CW decoders. This particular reader was asking about using their transceiver’s built-in CW decoder along with pre-programmed CW exchanges. The Reverse Beacon Network (RBN) uses CW skimming to spot CW activators 24/7. In the field, you could also use a laptop or tablet to do the same thing. ![]() Built-in transceiver decodingĪt home, you can also use powerful CW skimmers on your computer–sometimes via SDR applications–to decode CW across the bands. It’s not always as easy and straight-forward as the example above (sometimes, for example, the DX may only send back a portion of your callsign with a question mark) but it is possible to work short exchange DX and DXpeditions without knowing much CW at all. The reason why this procedure is so easy is because you only need to recognize your own callsign in CW the DXpedition at the other end is doing all of the hard work by picking callsigns from the pileup and replying.Īnyone could learn how to work these short DX exchanges in CW over a weekend. My only skill would be knowing what my callsign sounds like in CW at 20-30 WPM. When the DXpedition sends back my callsign and possibly a signal report (“ K4SWL 5NN“), I then press the memory button with my reply (“ 5NN TU“). I simply press the memory button with my callsign to call the DXpedition.
