To work a DXpedition in CW, for example, I would only need to program the following two messages in my CW memory keyer: How do they do this? It’s simple, really: DX exchanges are incredibly simple and formulaic.įor example, in order to work a typical DXpedition the only CW one really needs to know is what one’s own callsign sounds like in CW at a relatively high speed. There are a number of DXers who effectively rely on CW skimmers, keyboard sending, and pre-programmed exchanges in order to work DX. It would likely be frustrating.”īefore getting into a field activation, let’s talk about one area where even modest CW skills can be used to snag contacts. His question was simple, “Could I activate a park with this sort of setup?” At present, he doesn’t know CW at all, but he’s starting to learn. The idea would be to get on the CW bands for experience as he’s learning CW. He even thought about using a keyboard-based keyer as opposed to paddles or a straight key. The learning curve is actually more modest than you might think, which is the reason there are so many new operators employing this earliest of communication modes.Ī reader recently asked if he thought he could get away with doing a park activation for POTA using the built-in CW decoder in his transceiver and an external memory keyer pre-programmed with a wide variety of exchanges and signal reports. Thing is, CW is a skill so there is a learning curve associated with it. Uses 12 VDC or 110 VAC with optional MFJ-1312D.Ĭopyright 2005-2021, Universal Radio, Inc.The Xiegu G90 in CW Decode mode (note the text at the bottom of the display)Īs more and more radio operators hit the field to activate parks and summits, many want to turn to CW to benefit from Reverse Beacon Network (RBN) spotting and also to take advantages of the inherent efficiencies of CW at QRP power levels. All commands, functions & memories can be done through the keyboard! Compact and handsome all-black metal cabinet measures just 6.25 x 2.5 x 6.25 inches.
MFJ CW READER PC
Keyboard input lets you plug in any AT PC keyboard (the keyboard is not supplied). There is a 190 character type-ahead keyboard buffer with low-buffer warning. Push-To-Talk (PTT) hang time to 5 seconds. Keying output delay up to 20 milliseconds. Farnsworth Mode with speed adjustable from 10-99 WPM. Input queue lets you storeĭigital linear speed control from 5-99 WPM. MFJ-464 supports direct keying output, has PTT output, built-in speaker, sine wave sidetone and more! Iambic keyer with dot and dash memories: automatic, semi, or hand-key mode.
MFJ CW READER SERIAL
You can repeat messages continuously, insert timed pauses within messages, insert an auto-incrementing serial number, have messages call other messages or insert embedded commands to change speed, weight, etc. The MFJ-464 has 4 message memories of 256 characters each. Keyer functions can also be changed from your keyboard or computer.
You can send CW or load messages using a paddle, keyboard, or through your computer serial port.Įasy-to-use menus and LCD display let you set all keyer functions merely by pushing buttons.
MFJ CW READER FULL
The MFJ-464 combines the latest millennium microprocessor technology with non-volatile EPROM memory for a full featured, low cost, high reliability design. Of course, nothing can clean up and copy a sloppy fist, especially weak signals with lots of QRM/QRN.
You consistently get solid copy from MFJ's high performance PLL (phase lock loop) modem. Simply plug in your MFJ-464 to your receiver speaker until the lock LED flashes in time with the CW. MFJ AutoTrak automatically locks on, tracks, and displays CW to 99 WPM. * Single or Iambic paddle or computer keyboard operation * Large 2-line LCD shows send/receive messages
MFJ CW READER CODE
A type-ahead buffer, message memories and adjustable speed get you ready to compete with the world's best hi-speed CW operators - and they won't even know you just passed the code test! The MFJ-464 gives you everything you need to have the ultimate CW Station: It makes working high speed CW a breeze - even if you're rusty. then watch CW turn into solid text messages as they scroll across an easy-to-read LCD display. Is your CW Rusty? Relax and plug-in the MFJ-464 Morse Code Reader/Keyer your operating station. MFJ-464 Morse Code Reader and Keyer MFJ464
