A nifty way to bring out any impurities in a carrier is to null it with your
notch filter. The carrier is nulled but the modulation is not.

Subject: [TenTec] CW Note on Jupiter
|
| I just had a nice cw qso with W8KEB on 80m. The keying on the Jupiter is
| very nice. No clicks or dit chopping like the JA rigs however it sounds
| exactly like the Pegasus. It has a slightly rough sounding carrier. If you
| are picky about how you sound on cw then you need to give it a listen. Ken
| had a nice 15db over S9 signal with some QSB. The rough note is more
obvious
| during deep fades.
|
| This is exactly why I sent my Pegasus back to the factory. Their engineers
| worked with it for some time before concluding that all Pegasus's have the
| same characteristic and apparently this has carried over to the Jupiter.
| I would have not noticed this problem were it not for some honest reports
| from seveal other OT CW OPs who gave me reports of "fuzzy carrier".
Perhaps
| the Fuzzy Carrier Commission should look into setting new standards.
|
| I suggested to Ken that he listen to his own carrier on another rig.
| Sometimes this can be deceiving however due to ground loops and overload.
| Employing the aid of a nearby ham is a better method. Trading stations and
| listening to your own rig on his is more telling.
|
| I must admit my disappointment. I will stick with the Omni C until
something
| better comes along..
