Keeping track of the baseline between RX/TX

I've read most of the threads here about baseline jumping around with changes in the resolution bandwidth, but with regard to RX vs TX:

160m is noisy tonight. The noise floor on my inverted-L is around -103 dBm. Ok, let's scroll the baseline so that it sits about -105. Looks fine.

Now key the transmitter. The baseline drops to around -127 dBm, which I assume is normal. The "problem" (if it's indeed a problem) is that the baseline now snaps up and down on the display between RX and TX.

Like I said - I "get" what's being said about the baseline changing with the RBW. I may not buy into all of it, but we'll see how it works out over time. This RX/TX thing, though has me reaching for the Dramamine... ;-)

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
