If you want to use TinyFSK (which has its own problems), connect a Mortty to the K4 ACC port, same as you would on a K3. If you don't want to solder your own DE-15 connector, or if your ACC port is already occupied, use a Y-BOX <https://bit.ly/Y-BOX> plus 3.5mm stereo to dual RCA cable to connect Mortty to K3 or K4. I have a few of both still in stock. It will take a few weeks to order more boards if there is sufficient demand. It could present multiple serial ports. one for CAT, one for FSK and one > for Keying. This is already in plan. The K4 provides two virtual serial ports via the USB cable (FTDI), one legacy 9-pin serial port, plus the 15-pin ACC port. Any of them may be used for FSK keying, PTT, and CW keying, using MMTTY or your logging software. This is keying via TXD, DTR, or RTS pins, with no external hardware required (unless using ACC pins). EXTFSK will be required on the virtual serial ports. The 9-pin legacy port will not require EXTFSK if your PC serial port or USB-to-Serial adapter doesn't require it (example: Edgeport/4).

TinyFSK has a problem. Using it with MMTTY and a Mortty, try the "send RYRYRY... forever" macro while using TinyFSK.FSK. Hear the problem? It hesitates every 32 characters or so. So its timing is not as "perfect" as claimed, at least not with that configuration. While I despise the following phrase as a SW guy (specifically embedded > real time operating systems): Hey, it's just S/W.

Lots of devices have attempted to emulate the WinKey interface, but none of them are 100% compatible with the chip. This includes RemoteRig boxes, the YCCC SO2R Box, the Mortty, etc. None of them will pass the WKTEST program ( https://www.hamcrafters2.com/WKTESTX.html), last time I tried. The RemoteRig emulator works OK with N1MM+, but not with Win-Test or DXLog.net (unless you select a unique option). These programs all use the WinKey chip differently. They work fine with a real chip not with the emulators. The only devices that pass the WinKey 100% compatibility tests are devices that use a real WinKey chip inside, such as those provided by the microHAM devices. Retooling the K4 to put a real WinKey chip or Mortty hardware inside, or attempting emulation via firmware, could delay K4 shipment or distract from other higher priority issues. It could also raise the price a bit. I don't think anyone wants to see either. Finally, there's no reason for Elecraft to try to take sales opportunities away from the manufacturers of WinKey and Mortty devices, is there? 73, Bob, N6TV https://bit.ly/Y-BOX ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
