SITUATION: The Sound Card interface you just installed (SignaLink, RigExpert, Soundblaster) is not sending digital tones through the transceiver. The natural conclusion you may draw is that the sound card interface or cabling is at fault. First, let’s verify that the software you are using is actually generating tones to transmit. To confirm your software […]


When working with circuit boards, particularly with ICs or MOSFET transistors on board, it’s a good idea to keep yourself and the circuit board at the same electrical potential. This is especially important in winter, as static electricity can build up and account for a few hundred to a couple thousand volts. As you’ve probably […]
