- Page 2 Operating the Ultra PicoKeyer Once your Ultra PicoKeyer is assembled, mounted in the cabinet and has the battery installed, it’s time to connect your paddles and transmitter or transceiver and take a little time to read this manual to learn how to use your PicoKeyer’s features.
- Page 3 The Ultra PicoKeyer has four memories, controlled by the four pushbuttons on the front panel. Operating these buttons is very simple and straightforward, and their use is as you might expect from a modern electronic device.
- Page 4 When playing back a message in setup mode you will hear the command itself, not its effect – message chaining, QSO numbers, pause and beacon mode are inactive while in setup mode. For example, you will Ultra PicoKeyer 27 January 2017 (Firmware V2.2)
- Page 5 To insert the contents of a MYCALL message, insert the command /Y, /Y1 or /Y2. /Y or /Y1 will send MYCALL #1; /Y2 will send MYCALL #2. Ultra PicoKeyer 27 January 2017 (Firmware V2.2) Page 5 of 21...

Page 6: Battery And External Power
The battery in your Ultra PicoKeyer should last for a long time – anywhere from several months to several years. Battery life depends on a few factors: ... - Page 7 If you prefer, you can use a 3.5 mm stereo plug to connect an external device for sidetone. This will disconnect the on-board speaker. The PIC processor chip used in the Ultra PicoKeyer can drive small ear buds or headphones with 32 ohms or greater impedance.
- Page 8 Using Your Keyer with a Handheld or FM Rig (“MCW” Mode) One of the unique features of your Ultra PicoKeyer is MCW mode (menu option “T” for sidetone, select “M” for MCW). In this mode, the keying output can be used to trigger the PTT input of a VHF or UHF handie-talkie or FM mobile rig, allowing you to use your FM rig for Morse code.

▼and ▲ buttons to change settings. “?” means you’re in setup mode, and “did dit” means you’re back in normal operating mode. Using the Ultra PicoKeyer’s setup mode is very simple and intuitive, with only a few very simple things to remember. - Page 10 Speed may be set from 5 WPM to 60 WPM. If you want to return to the default 13 WPM setting, simply press and release buttons 2 and 3 at the same time. Ultra PicoKeyer 27 January 2017 (Firmware V2.2)

Page 13: Before You Start
Before You Start Your Ultra PicoKeyer kit was designed with the beginning kit builder in mind. With just a little care and practice, even a first time kit builder can complete the project in a relatively short time. You will need to gather a few tools and supplies together before beginning to assemble your kit. - Page 14 Just soldering the pins on the bottom of the board like any other through- hole part is enough. Ultra PicoKeyer 27 January 2017 (Firmware V2.2) Page 14 of 21...
