A simple dart library that transforms the reverse beacon telnet CW and DIGI servers into a controllable broadcast stream.
This library is designed to be used in client applications, hence the exposed exception types.

this project is in no way officially associated or supported by Reverse Beacon, but I certainly appreciate everything they do. And obviously this wouldn't work without them
import 'dart:io';
import 'package:reverse_beacon/reverse_beacon.dart';
import 'package:reverse_beacon/src/cw_spot.dart';
void main() async {
var rb = ReverseBeacon();
try {
await rb.connect(callsign: 'n1bri');
} on TelnetCommunicationException catch (_) {
print('Telnet Communication Exception');
exit(-1);
} on InvalidCallsignException catch (_) {
print('Invalid callsign');
exit(-1);
} catch (ex) {
print('unknown issue');
exit(-1);
}
int spotCount = 0;
rb.listen((spot) {
//filter
if (spotCount < 5) {
if (spot.band == Band.meters20 && spot.mode == Mode.cw) {
if ((spot as CWSpot).wpm >= 15) {
print(spot);
spotCount++;
}
}
} else if (spotCount >= 5) {
if (spot.band == Band.meters20 && spot.mode == Mode.ft8) {
print(spot);
spotCount++;
}
}
if (spotCount == 10) {
rb.close();
}
});
}
Output Ex.
