Yes the S-BOX is designed to key FSK and PTT on a K3 ACC port, providing the traditional NPN keying circuit, with no Y-BOX required (though it may be convenient to have as well, depending on what else you need to connect to the K3 ACC port). Straight 9-pin and 15-pin D-SUB cables handle everything, no need to use the S-BOX RCA connectors if you have a K3 or K3S. There are four independent keying circuits inside the S-BOX, so you can key FSK on two radios with the one box, or CW/PTT on one and FSK/PTT on the other, if you like.
See these links for a sample connection diagram and schematics: https://www.kkn.net/~n6tv/S-BOX/Features.html#RemoteHams https://www.kkn.net/~n6tv/S-BOX/Features.html#SO2RRTTY Many other configurations are possible. If you use a USB-to-Serial device by Edgeport, MMTTY can open open the serial port directly at 45.5 baud Baudot. If you use one based on FTDI, such as the one built-in to the S-BOX-USB, you need to use EXTFSK or EXTFSK64 with MMTTY since MMTTY standalone cannot open these directly at 45.5 baud. The K3 produces very clean FSK. AFSK can also work but there is more potential for RFI problems and getting the audio levels set just right. 73, Bob, N6TV https://bit.ly/S-BOX On Thu, Aug 30, 2018 at 6:53 PM, Peter W2IRT <[email protected]> wrote: > I went a similar route with a MicroKeyer MK-II.
