How can I tell if I have jitter with my K3 running FSK? Exactly what is
jitter?
Tnx
N2TK, Tony

TinyFSK only solves the timing issues.  FSK bandwidth is determined by the
radio.  Fortunately, you use the K3 which is the rare (only?) one that
filters the FSK signal.

I understand that MMTTY FSK and Windows results in transmit jitter.

I use MMTTY K3 FSK. 2Tone tells me I have jitter.

I understand that my jitter reduces copy-ability (somewhat) for stations I'm
working.

Question: Does my jitter increase my transmit bandwidth?

Or put another way: If I switch to TinyFSK, will my transmit bandwidth be
reduced?

If yes, by how much?

Diddle Exuberantly,
