Thanks Rich.? I understand that what I am seeing is what fldigi intends to send, and that's why I am asking about this -- I am trying to figure out if what fldigi intends to send has more spectral artifacts than desired before it even gets to the radio.? ?I indicated that it is not connected a radio to rule out the possibility that there being some sort of sample rate incompatibility with the virtual audio connection.? And when I say "carrier", I mean center frequency, understanding that no carrier is present.? The picture of the signal scope is just transmit with no on data going out, while the spectrums are showing sending data.

The "dropped samples" even occur for multiples of 31.25 Hz.? Here's 500 Hz:

Hi Curt, A couple of comments come to mind. Bear in mind, these are based on my understanding of fldigi...I'm not a dev. 1. The picture below is with no transceiver connected -- only the output of fldigi affecting the waterfall: ...but that is always the case. fldigi can't sample what the radio is sending for several reasons. So the fldigi TX audio stream is limited to just what fldigi ~intends~ to send. In fact, fldigi can't tell what the CODEC is sending to the next device downstream. It might be some piece of hardware, such as digirig, and it might be going directly to a radio. fldigi doesn't know. So for output, what you see on the waterfall is what fldigi has composed to send. 2. What psk? Is this just a Tune tone ? Remember...this is what is sent to the radio, so there is no carrier in play here. 3. harmonics (low level though, <-60dbc ) far away from the carrier in the waterfall when I transmit. It looks like you are showing us the SIG display. You will see the harmonics on the FFT display. Remember, fldigi composes the waveforms digitally. Someone else will have to ring in with the details. But IRL, the audio stream consists of fldigi composing a waveform at some freq (here I mean the sampling freq, not the waterfall freq), then the CODEC in play (you mention a CODEC with "native" sampling rates; I use 48000)...those 2 will create a complex wave with an approximation of the envelope you want for the chosen modem...then any intermediate devices, and finally the radio (which I understand is not in play here). 73 Rich

artifact.? Try setting the center frequency of the bpsk31 signal
to 500.

Some stations do if they really are looking for contacts. There are settings in fldigi to tell it if you want to jump to the station freq or just be notified of if and what the mode is.

Re: FLRIG OK, FLDIGI quit working?
Hmmm... To delete all the files just delete the fldigi.files directory. Fldigi does not use any files outside that directory unless you have specifically told it to do so and that would be configured by settings within the fldigi.files directory.

Jay,
Could be a corrupted fldigi config file.
You can test for that by going to c:\Users\<loginname>\fldigi.files and rename the flidigi.prefs file then try to start fldigi. If that works then you're good to go. If not then rename the fldigi_def.xml file in the same directory. That will cause you to need to setup fldigi from scratch. Just do a basic minimal setup then close fldigi and restart it. If it's ok then finish reconfiguring fldigi. You'll still have macros, logs, etc from the old config. It that doesn't solve the issue then go back and delete the newly created fldigi_def.xml file and rename the old one back to fldigi_def.xml to restore the old config.
Hi Group,
Had something unusual happen: I had FLRIG-FLDIGI working just fine with an IC-7300. Yesterday, FLRIG seemed OK, but FLDIGI pops up for two seconds and then disappears.??
Any suggestions?

Fldigi 4.2.05 Fails to run on Win 7?
I am attempting to run the latest version of Fldigi 4.2.05 under Win 7. It seems to load okay, but at startup I get the error:
?
Assertion Failed! Program ...
Fldigi.exe ? src/hostapi/wdmks/pa_win_wdmks.c, ?Line 1061
?
The decode works fine, but it will not transmit. The application looks like it is sending sound, but no sound is going out, even though the sound-card is set properly. This works fine with Fldigi 4.1.11 and the same configuration settings.
?
Is there any resolution besides using a later version of windows or Linux instead?
?
Thanks, Corky

Reduce the monitored transmit signal level.? This is actual just an
FFT transformation of the transmit audio signal.

Thanks Mike-
Moving the left control (UPPER SIGNAL LEVEL) to -51 shows
dark blue background and received signals in yellow.? ?(SIGNAL
RANGE) was at 60.??
My transmit signal with these settings is red with yellow

Bottom left of FLDigi when the button says "WF" there are two controls for the waterfall view. You are correct that you should not need to change anything on the rig.
Adjust the two controls up/down to see the effect.
Normally you would decrease the left (upper level) until you see a blue background -- then increase the right (signal range) until you see the signal the way you like.
