Yes. Can you do it without "a maze of impenetrable software solutions"? No, but once you get it set up, it won't be too bad.

Since W2IRT has a K3S and KPA1500, no serial connection is needed between the K3S and the amp. The 15-pin ACC cable between the K3S, KPA1500 and Y-BOX handles all required communication. Did mean VSPE <http://www.eterlogic.com/Products.VSPE.html>? Here are the steps to share the K3S virtual serial port between N1MM and MMTTY and use AFSK RTTY. This method uses the K3S virtual serial port RTS line for "Hardware PTT" from MMTTY to avoid potential command conflicts that are possible if you try to use "Radio Command PTT" from MMTTY. *K3 Setup:* CONFIG:RS232 USB (In the VSPE setup below, I assume *COM5:* is the FTDI serial port created by the K3S) CONFIG:RTS-DTR PTT-OFF (for computer-generated CW, you will have to change this to CONFIG:RTS-DTR PTT-KEY) MAIN:MIC SEL LINE IN (make sure *nothing* is plugged into LINE IN or LINE OUT on the rear panel of the K3, otherwise you get zero audio on the K3 USB sound card) MAIN:MIC+LIN OFF (for SSB, you may have to set MAIN:MIC+LIN ON) *Windows Setup to make the K3 USB Sound Card work in Stereo Mode so you MMTTY can decode both Main and SubRx:* 1. Windows Key + R (run): mmsys.cpl (shortcut to open Windows sound control panel) 2. On the *Recording* tab, select the K3's *USB Audio CODEC* and click *Properties* 3. On the *Advanced* tab, select *2 channel, 16 bit, 48000 Hz (DVD Quality)* and click *OK* 4. Click *OK* again *VSPE Setup:* 1. Device | Create | Splitter 2. Virtual Serial Port: COM6, Data Source Serial Port: COM5 (or whatever the K3 USB cable created, check Device Manager) 3. Check *Redirect Modem Registers* 4. Under Initial modem registers state, *uncheck* both RTS and DTR 5. Click OK 6. Click Start emulation *N1MM Setup:* As you were doing before, but use COM6 for rig control instead of COM5 (For CW, specify CW keying on the DTR pin of COM6, PTT on the RTS pin) *MMTTY Setup:* 1. From the menu, *Option | Setup MMTTY* 2. On the *TX* tab, under PTT & FSK, set Port to *NONE* 3. Click the *Radio Command* button 4. Set Port to *COM6* using the same settings as N1MM, (e.g. Baud: 38400, Data Length: 8bits, Stop: 1bit, Parity: None, Flow control: none) 5. Very important: under *DTR/RTS*, check the box labeled *PTT* 6. Very important: at the bottom, set *Group* to *Clear* so no radio commands will be sent by MMTTY and only hardware PTT will be used 7. Click *OK* 8. On the *SoundCard* tab, set Reception and Transmission to *USB Audio Codec* 9. On the *Misc* tab, select Source: *Left* for Main Rx (VFO A) and click *OK* 10. If you also want to decode Sub Rx (VFO B), you must configure a second independent instance of MMTTY (launched from a separate directory) but select Source: *Right*. Perhaps you already had that working. Of course you'll have to do further fine tuning to adjust audio levels as required.
