Now is where the interesting part comes in. Trying to get MMTTY or
WinWarbler to run FSK has been a total disaster. I did manage to get CW
working, so PTT and the serial connections are OK. Have disabled the
on-board RealTEK HD Audio card, and installed a Creative Audigy ZS which has
Line In/Out, as well as MIC in. This card worked well on the old computer
under XP, so no suspicions as to the cards??? function.
Are you running the current version of WinWarbler (5.8.7)?
WinWarbler soundcard is set up with ???What You Hear??? for Reception and
???Speakers (Creative SB Audigy )??? as Transmission under the soundcard setup.
If you are transmitting via FSK, there will be no audio output.
I am getting good audio to the decoder and it decodes incoming RTTY fine.
MMTTY set up OK to do FSK. However, when I transmit (both programs) I get
PTT activation and a steady carrier out ??? no modulation. Audio in from Rig
(ACC plug) is OK to the RigBlaster. Line Out from the RigBlaster to the
soundcard has audio, but at perhaps ??? the level of the audio coming into the
RigBlaster. Anyway, getting receive audio OK. When I check line in from
the soundcard, there is no modulation ??? nothing out of the soundcard back to
the RigBlaster while transmitting, so no FSK input on the PRO III. Also,
nothing on Line Out of the RigBlaster to Line In of the Soundcard when
transmitting.
Transmitting by FSK (as opposed to AFSK) means using a serial port TxD,
RTS, or DTR signal to convey the "information to be transmitted" through a
level converter that then drives the RTTY or FSK input on the back of your
transceiver. It sounds like you have Winwarbler configured for FSK but are
"cabled" for AFSK.
