The G4JNT Programmable Beacon Keyer
New QRSS (SlowCW) Option now available
Beacon Keyer with Analogue Input
Using a 12F675 PIC with internal A/D converter. A voltage in the range 0 - 5V is measured and can be sent back
in the CW message in a number of different formats offering user-defined accuracies and complexity.
The reading can be embedded anywhere within the CW message and can be sent at any speed.

12F629 PIC based beacon module offering CW messages, Programmable pauses, Tx/Rx control.
The module can be re-programmed over an RS232 link so a PIC programmer isn't needed to alter
the message data.
Please state on ordering if you want the QRSS version. PIC Code for both is included within the archive
Use, for example, to allow a beacon to transmit its own measured RF power as a user confidence check.
