Keying sidebands

[Bob Henderson]

I notice a frequency based anomaly and wonder whether anyone else might have seen the same effect and perhaps know what causes it.

On all bands except 12m TX keying is cleanly displayed on the Thetis pan adapter as are received signals.  On 12m both the transmitted signal and all received signals appear to be very wide with multiple sidebands.  A separate RX tells me that transmitted CW on 12m is clean, sharing characteristics common to other bands and suggesting the anomaly is just HL2 RX based.

Hi Bob,

There is no known anomaly regarding 12M and the HL2. All bands are handled in the same way internal to the HL2. If there is a difference for 12M, it must be in any unique 12M hardware filtering you have or 12M software settings.

Thanks Steve.  I will investigate further.
