2HS3433 How to connect a paddle/key to HamSphere CW system! 2013-09-19 19:52	Registered: 12 years ago Posts: 89

Here is a nice set of instruction on how to connect your keyer up to HamSphere.................... by Peter 9H1RN/BV Nothing could be simpler. Sound out of headphones socket on Laptop to Radio In of Keyer Unit. Sound out of Radio Speaker on Keyer Unit to Microphone/Line-In socket of Laptop. This forms a closed loop as the photo of the circuit diagram shows that the sound passes straight through the Keyer Unit. The keyer side tone being added to the sound (line TxAUD) as it passes through the Keyer Unit. The problem is you can’t hear any sound because of the closed loop so a breakout has to be added. Hence the 2 into 1 stereo connector at the Laptop. As it is a closed loop the connector can be placed into either Laptop socket. This is where I plug in the headphones so I can hear the received signal. When I go to transmit the side tone then goes to the Line-in socket. Hereafter it’s just a matter of getting the right audio levels. I set the Hamsphere Volume to Max and use the laptop buttons to set the receive volume. The level is the minimum to light the Lock LED on the Keyer Unit. The Keyer Unit then decodes the Morse received. I have a volume control on my headphones to adjust to a comfortable listening level. I set the volume control on the Keyer Unit to the same minimum level to light the Lock LED when the paddles are operated. This gives the same audio level as the received sound. I set the correct level of ALC in Hamsphere on keying with the PTT pressed. When operating I have the VOX active with a level of 2, the PTT hold is off so Hamsphere automatically transmits on the start of keying the paddles. The advantage of this method is that my Morse sounds do not upset anyone else in the household or vicinity and I can operate into the late hours without disturbing anyone. If you have further questions about this set up you can contact Peter - 9H1RN/BV . Like to thank Eric - 44HS852 for submitting a request to post this information.
