Amateur Radio Victoria's Morse code beacon VK3RCW is being used by radio amateurs to to increase their speed allowing them to join the CW mode on the bands.
This interactive beacon is at Waverley in Melbourne's east. On 145.650 MHz and operating 24/7 the VK3RCW beacon invites access to its menu via DTMF codes on 433.050 MHz.
Well how does it work?
Built by David Byrne VK3DRB using his expertise with things digital, it has wide coverage and features the well-known voice talent of Jane Holmes.
Using DTMF codes via the control input of 433.05 MHz you press 1 to select the menu, 2 to change speed, 3 for the tone of emission (400 - 600 - 800 Hz), 4 to change content and 5 to read back the text.
The DTMF tones can be generated using a DTMF microphone, mobile phone or be computer generated, with a microphone held in front of a loud speaker.
In a clear voice Jane Holmes will ask a user to 'hold the line' and this is where you need to listen for the result on the VK3RCW output frequency of 145.650 MHz.
