I focused on using easily available slotted optical switches in my design. The CW50A microprocessor-based electronic keyer works with any transmitter or transceiver. Iambic is where the dash would output one pin and the dit on another pin and in combination would result in a Morse character. my paddle skills are lacking. Also I am including the circuit diagram, diagram of connections and CLEAR ENGLISH INSTRUCTION how to use this CW Keyer and using the CW Key. Only at eHam. A Arduino-based CW sidetone generator and keyer. This is a simple straight key I built from scratch. CW Interface. Yep, yet another keyer circuit! This one uses the PICAXE-14M2 chip and is programmed in "BASIC". Features of the PicoKeyer-Plus: Dual MOSFET keying circuit will key. A bit of thought and it suddenly made sense…. Born in Bradford, Pennsylvania in 1930, John Curtis became the typical boyhood ham. Morse Paddle Keyer his is a circuit that I particularly like due to its simplicity and speed of construction. A really easy way to do this is to take an old USB mouse (or even a new cheap one) and solder the key across the left mouse button. You will be able to send and hear morse. The interface end of Fig. The same circuit can be used for a straight key. This is a small demonstration of a simple morse CW keyer, homemade. The original HD-1410 keyer is designed using 5 commonly available 74LS series TTL ICs and 8 transistors. Here's the circuit I hooked up. The completed project uses a rotary encoder, another first for me and four memory buttons. I made the first keyer in 1980 and the second one in 1999, so it is an old but a very nice design and it deserves to be published more often. Iambic keying or squeeze keying creates alternating dits and dahs. Porting the code I found out that removing code from a sketch is almost as difficult as putting it in. I ordered two new chips plus a complete unit with circuit board to install in my HW8 someday. Keyer paddles are integrated into the PaddleStick circuit board which allows very compact layout. As an old flow, breadboard plug-and-play is the fastest way to work for it. Bill Ward (KD4ISF), Guy Dickenson (KD7TJJ) and Dave Clausen (W2VV) setup a club call sign N2YCR and a remotely operated computer station running fldigi for PSK31. It has tunable code speed, code weight, and sidetone frequency; it supports both direct and grid-block keying outputs. Beware I am not a programmer by profession or as a hobbyist! But the code seems to work OK. The firmware is written in C and uses less than 1k. The Icom series of radios from the IC-746 Pro on to the latest 7800 radios have a 4 memory digital voice and CW keyer built into the radio. Provides a physical speed control knob 4. The receiver RF Front End circuit is the most important element because it ultimately determines the HF Receiver performance. QRP (or not) PIC-Keyer by DL4YHF. Iambic Keyer Using 4000 Series CMOS. The voltage across pin 2 is actually slightly higher than pin 3. The Iamabic A, Iambic B and the handkey sending works very well. The paddle must be connected to a COM port as shown on this diagram. For the past few nights, I've been trying different circuits and deep-diving the design of Jim Ricks' (W9TO) original tube keyer, the Hallicrafters HA-1 and HA-4 variants, Heath's HD-10 and W2YM's keyer from the Spring, 1964 edition of RCA's Ham Tips. Firmware Beta Release. I have received an interesting email from Grant/VK2GEL in Australia. Quite a few operators have been talking about how to use a mouse for a key, on cwcom. Spiderbeam antennas and poles. Outline specification. K1EL PaddleStick Keyer with Base Kit PS2B PaddleStick Keyer & Base - A. A Arduino-based CW sidetone generator and keyer. I have long since lost the magazine and the notes that I made at the time. That being said, there are many PTT/Keyer circuits out there.
