Thanks to all who replied off-list to my question about choosing a Mark
frequency. Now on to a new question....
Last night I was receiving RTTY using MMTTY and the AFSK-A mode on the
K3s. This morning I am trying to get the K3s to transmit, but not having
much luck.
I'm using the internal USB sound card in the K3s. I have successfully
configured MMTTY to:
1. Receive and decode tones from the sound card.
2. Key the K3s when I click the TX button in MMTTY.
3. Send tones to the K3s when the TX button is clicked. I can hear the
tones in the K3s speaker and headphones. If I choose a different Mark
frequency in MMTTY, I hear the expected tones on the K3s.
Clearly audio tones are being sent to the K3s. But no RF comes out. I
have PWR set to 50W (into a dummy load), and when I hold TUNE, the RF
bar graph shows that power level (half scale, 5 bars).
But when I click TX in MMTTY, and hear the tones on the K3s, the RF bar
graph shows 0 (one bar).
What must I do to make the K3s transmit the audio it's receiving from MMTTY?
Thanks in advance.
