Barney, Re the first problem, I suspect your LINE IN level may be sitting on zero. With the radio in DATA A or AFSK A mode, make sure your MIC SEL is set to LINE IN (I believe this is the default in DATA A and AFSK A modes, but if not you can set it using the MENU button). Now turning the MIC gain control will adjust the LINE IN level. You should set the meter to display ALC and then adjust the LINE IN level (and/or the SignaLink's output level) until you see 4-5 bars of "ALC" reading on the K3. Use the PWR control to select the desired output power. In modes that require high linearity, like PSK, stay below one-half the radio's power rating (i.e. between 12 and 50 watts or below 5 watts) to avoid clipping on momentary peaks.
Re the second problem, is your SignaLink connected to the radio's PTT input? If it is, you should make sure that your software is *not* configured to control PTT. In particular, make sure that it is not using software commands for PTT. Also, you should turn the radio's VOX off. The SignaLink has its own VOX circuit that controls PTT for you. There is no need for an additional PTT method, and in fact using two methods simultaneously can cause this problem. The K3 appears to be vulnerable to a "race condition", in which sending a software RX command simultaneously with switching hardware PTT (or the radio's VOX) can leave the radio in transmit. 73, Rich VE3KI K3LA wrote: > I recently tried to set up my K3 for data usage and two problems arose.
