The radioclub has a CW robot since 2006 for bilateral telegraphic links on the 10m radio band. Frequency is 28,110kHz in JN18bw.
|Frequency (TX & RX)||28,110 kHz|
QSO logs are available here:
What is a CW robot?
The robot is made from a vertical antenna, a transceiver on fixed frequency, linked to a computer running a program. This program decodes morse coming from the receiver into strings (and the other way around). The decoded strings are compared to the ones stored in a database in order to generate the right answer according to what was received, and to transmit it into morse.
The robot imitates a real telegraphic operator by trying to sound like one and adapt in several situations. It has to:
- decode a transmission not always perfect (timing issues)
- manipulate at the same speed as the correspondent
- check the validity of the callsign, check the right repetition of the callsign and check if the QSO has already been made
- keep track of calls and archive them
- answer questions aksed by the correspondent
- when a received message is not understood, it repeats what it heard
- create a QSL card on a website to confirm the bilateral communication and keep a log file on a website
- make beacons (CQ) at regular intervals giving instructions on how to make contact
