The simplest and quickest computer to radio interface is to connect the Line Output from the Sound Card to the transceiver audio input with a 100:1 voltage divider to reduce the voltage output, and the Sound Card Line Input to the audio output of the radio. You can use the VOX to switch from Receive to Transmit. To setup this arrangement, adjust the sound card output level using the computer 'mixer' control until maximum transmit power is reached, and the ALC is just starting to read. Then tune to a strong carrier and adjust the soundcard input gain until the red line goes away as observed on the spectrum display. waterfall (indicator) This procedure is covered in great detail in the PSK31 Help files under "setting up the sound card".

 

 

The circuit below shows the method I used which isolates the Sound Card Line In and Line Out from the Radio using a couple of Radio Shack transformers, and a 2N2222 transistor to switch the PTT radio line triggered by the RTS line of the computer Com Port. All audio levels are equalized when running either the computer, the SSTV program or PSK31.  To adjust this circuit, tune to a strong carrier and adjust the Rig Volume until the red overload lines disappear. At this point simply tweak RV1 to give the required output power from the transmitter.
The author of this page, WM2U, would greatly appreciate any technical updates and or Interface Schematics sent via e-mail. This would ensure the most current information is available to the user, however there is more Radio to Computer interfacing help on the Hook-up page. Try this if you need more information.

 

 

Qui sotto sono riportati alcuni schemi per comandare il PTT della Radio.

 

Questo con un transistor 2N2222 o BC 278 sistema classico.

 

 

Questo circuito serve per comandare il PTT, e tramite

il Fotoaccoppiatore 4N25, 4N29, ECG 3084 o equivalenti si può

isolare completamente il Computer dalla Radio.

 

 

The calling frequencies that have been decided upon for the time being are:
1838.15kHz, 3580.15kHz, 7070.15kHz, 7035.15kHz, 14070.15kHz, 21080.15kHz, 28120.15kHz, 50.290mHz, 144.144mHz, 222.07mHz, 432.2mHz, 909mHz and
10137.15kHz, 18100.15kHz and 24925kHz suggested for the WARC Bands.

 

 

  • Set sound card sampling rate to 11025Hz

  • This must be at least a 16 bit sound card.

  • No Signal observed? Check your WAVE slider is not zero.

  • Set Rx and Tx frequencies to 1000Hz.
    NOTE: This value will get you up and running but if you plan on using a filter change it to the center frequency.

  • If using LSB check the "Inverted QPSK" box.

  • Too much noise! Try using a narrow CW filter.

  • Using a Word Processor, write your buffered messages and save them as .txt files, placing em! in a folder called 'buffers' created in the main PSK31 folder.
    NOTE: This is NOT a form of type ahead buffer. It is simply a method to pre write 'Standard' messages hence saving you keyboarding time.

  • READ THE HELP FILES.

    • Your sound card output must NOT overdrive your Mic Input.

    • Do not overdrive the sound card input from the Radio.

    • Get used to the Waterfall/Phase indicators for tuning.

    • Do not use your Speech Processor.

    • Be patient. This is a new mode. You will not find all the features you are used to yet! ù
