The design of the SignaLink allows easy access to the internal components.

This modification also requires the use of a serial port adapter, you can build one for pennies read this article, and two 1N4148 diodes. This method works quite well, but it must be remembered that the SSB frequency may need tweaking to align with the CW frequency.Īny modifications will invalidate any warranty and are carried out at your own risk.

Using this “standard” method of connecting the unit CW with the unit is only possible by configuring the PC software to send the CW as an audio tone and transmitting using SSB. If the RJ45 cable is terminated to the correct pins and the jumpers installed correctly inside the SignaLink everything should work fine. However any audio passed to pin 11 is transmitted making this socket ideal for digimode operation. What is interesting is the fact that by connecting pin 9 to ground, the radio is placed into transmit, with the microphone input muted. Of particular interest are pins 3, 4, 9 and 11 of the ACC socket. This is of interest as although it was originally designed with using a TNC it can be used quite successfully with the SignaLink. The Kenwood TS-850 transceiver has a 13 pin accessory (ACC) socket on the rear panel. The logic within the unit also places the transceiver into transmit mode while it’s receiving the data stream. Suitable software then decodes the digitised signal.įor transmission the software sends the data to the SignaLink unit where it is converted into an audio signal and then passed to the transceiver. When the radio is in receive mode the unit converts the received audio to data and sends it to the computer via the USB cable. In use, the SignaLink is essentially an external USB soundcard and transmit/receive controller. Tigertronics also supply pre terminated RJ45 cables and pre-configured jumper blocks. Wire jumpers inside the unit allow the SignaLink to be used with any radio. The other end of the RJ45 cable is terminated to suit the radio. The connection to the transceiver is made by a RJ45 (ethernet) socket on the rear of the unit. The latest version of the SignaLink connects to the computer using a standard USB cable.

All the spacing was locked to ideal morse code at the speed it averaged from receive.A SignaLink is a small unit manufactured by Tigertronics which functions as an interface between a computer and transceiver to enable the use of digimodes. It took what it got timing wise from the sender and used that to transmit back. The program would do a guess to supply a missing dot or dash to generate a character based on what it heard and looking up valid Morse code characters. Those who used iambic keyers, vibroplexes and such it would do real well in getting a proper decode. It even calculated the approximate speed in WPM and displayed it. I used a subroutine that checked once a second to see when the characters were actually arriving and the length of dots, dashes and spaces the operator was sending adjusting the sample timing to fit. It started out at 8 WPM using the weights suggested for sending proper CW. Click to expand.Way back in the dark ages of 8bit I wrote a 6502 machine language cw decoder program on the Atari.
