QRQ Keyer
Advanced CW keying with Bluetooth connectivity
WinKeyer3 Compatible Bluetooth Keyer
Keyer is primarily developed for learning and practicing telegraphy (high quality side tone and built-in AF amplifier) however, the ability to connect it wirelessly to a PC or smartphone (not iPhone) via Bluetooth virtual RS-232 serial port (internal Bluetooth serial port module) gives keyer wide application.
The aforementioned features make the 9A5N QRQ keyer completely different from other keyers on the global market that use a USB wired connection to a PC and have square waveform side tone that plays on the buzzer.
