 TX/RX CW signal (VFO A only) on 14.012MHz but I also see my signal on 14.008 and 14.016MHz.  Is that normal?

    Steven,

    How are you "seeing your signal"?  If you are using the pan in TX monitor then I believe this is totally normal.  You are talking about a sensitive receive circuit enabled next to a  transmitter.  I think you will see lots of little overloads.

    I agree with Mark, you will see very a very wide signal with spurs when looking at your xmit signal in the panadapter .  If your concerned, listen to your signal in another receiver with lots of attenuation.

    Also make sure your DSP filters are not enabled which also causes artifacts in the Display

    Yes, that is totally normal.  You have a very high dynamic range spectrum analyzer/receiver inside the same enclosure with a 100W transmitter.
