Span and center frequency jumping

[sm6fhz]

Hi.
Is there a way to lock the center frequency of a desired span from moving when changing receiver (receivers spread across the full band) from one at one end of the span to one at the other end of the span?
As illustrated in the attached screenshots the wanted center frequency of 1100 kHz to another frequency when choosing a receiver at the far end of the desired span.
This results in one or more receivers fall outside the span and the spectrum and waterfall gets black.
I would like to be able to keep the same center frequency and span even when jumping between different receivers.
The span also changes from the wide setting (first screenshot) to a more narrow setting when stopping and starting the radio again.

This is the reason - see attachment.

Thanks Simon.
Seems like it cured the blank extreme receivers Easy when you know how to.
However, the more narrow span shown when stopping and starting the receiver still is in effect. But, that is not important at all. Would be interesting to know why it does like that, if there is a reason for it.

Let's put it down to inadequate programming by me .

OK Simon. It is not a problem at all. Just curious.
Spend you time with more valuable things

Thanks. Some aspects of UI code require quite some thinking and making changes can be very dangerous. I'm hoping to get 3.0.26 stable so I can release 3.1 in January 2021 and put 3.1 on long term support.

Currently doing a little programming for myself then later today taking down the HF antennas and concentrating on VHF and above.
