K3: PSK D ASCII mode

[Barry Pfeil]

The owners manual (Rev D1) that came with my SN1774 K3 says, on page 31, that "...PSK D lets you transmit via FSK IN, ASCII, or the keyer paddle".  I take this to mean I don't really need a transmit audio connection from the computer my PSK31 software runs on to the K3.  Apparently the transmit data would travel over the same RS232 interface I've implemented for my contesting software and the K3 would create the PSK "warble" internally.  Very cool, BUT, everything I read in the reflector archives talks about audio, not ASCII, interfaces for transmit on data modes.  Is this ASCII feature implemented in the K3?  Do the PSK programs now have such an option implemented?  My hands-on PSK experience is dated and with Digipan only.
  Thanks es 73,
Barry, K6RM

The K3 utility that you use to update firmware has a sample
implementation under the "Terminal" tab. I've not heard of any "real"
software adding support yet, but the potential is definitely there...

My Elecraft logging program KComm supports the KY command used to send data via ASCII to the K3 and could be used in PSK D and RTTY D modes but there are some shortcomings in the K3 implementation so I haven't really tested it as I don't consider it usable for any serious purpose. There is no way for the computer to send the equivalent of the IM prosign you can send on the key to terminate the transmission, so you have to wait for it to "time out". There is no support for newline characters and everythging is sent in lower case so the output looks odd in PSK31. And there is no way to get the received data back into the logging program so you have to watch the scrolling 7 character display on the K3 - if you miss it you've lost it.
