Maintaining Freq span

[N1IA]

Hello:

Perhaps it is just me, but I am having trouble figuring out how to keep the freq span in the display after zooming in. The default seems to be 0-100 khz. I've tried all kinds of things to keep the span coming up every time I go to that band, but it keeps snapping back to 0-100 Khz (i.e.: 20 meters). I wish to set it to only the CW portion on each band, namely 14.000-14.072

Can anyone tell me what I might be doling wrong?

Thanks
Scott N1IA

The easiest way to set up a preset span and make it recall that way every time is to use Favourites as your bandswitch rather than inputting the frequency direct. Favourites can store a good many parameters, including the frequency span (assuming you have that top tick-box selected when you save). So set up span of 75 kHz (or whatever) before you press "Save".

Thanks for the reply Max. Here is what is happening:

I have tried to ADD a new favorite but the only SPAN it shows is 000-100 khz with a check box ntext to it.
Should I be changing the parameters at the bottom of the display? There are span adjustments there but they won't hold when going back. When I do that it only holds until I click on the existing favorite which brings me right back to 14.000-14.100. And there is nowhere to change that that in the ADD FAVORITES menu that I can see.

Ideas?

Thanks
Scott

Firstly, you can either ADD or UPDATE a Favourite, so to change an existing one, recall it, then make adjustments to whatever you want to change, then, making sure the tick boxes are checked for the parameters that you want to update, press UPDATE and then OK. If you are programming a new Favourite then same procedure except it's ADD then OK.

The easiest way to adjust the span on your already programmed Favourite prior to saving is to set your centre frequency first, then looking at the "span" bar right at the bottom of the display (the highlighted, light gray slider bar) left-click and DRAG the outer edges to set the span you want, then UPDATE and OK.

I hope this helps a bit? Just for sake of clarity I attach picture of the bar that you need to drag the outer edges on. In mine I first entered frequency of 432.180 MHz then dragged out the edges of the span bar to 10kHz up and 10kHz down so the span is now 432.170 to 432.90MHz.

Also have a good read of the link I sent in my last post. It does pretty much explain the steps needed to save and/or update what you want to. I have my Favourites all set up to be bandswitches this with varying spans for varying modes, so for FT8 for example, my span only covers about 10kHz display width. For the general band switch, 20m band for example, it's set to cover exactly 14.000 to 14.350MHz. For 20m CW, 14.000 to 14.100MHz.

Hope that makes sense.

Thanks Max. I couldn't edit the existing the way you described. However, after first setting up the spans and THEN creating the favorite, I was able to get them all set properly.

I greatly appreciate the help!

Hi Scott. One thing I did not ask is which version of SDRC you are running? If not 3.4 Beta then I strongly suggest updating. It is very well tested and stable for many months with no unresolved issues reported. I recall that a few months ago Simon did some work on the Favourites and you may not be seeing what I'm seeing when it comes to updating and selecting options, as Simon added several optional tick-boxes that allow saving of different parameters. That may explain why you are not able to do what I've described.

Suggest update (if not already on v3.4) to:

Hi Max:

I checked my version and it is the latest "3569" update. Anyway I have my CW, FT8, and FT4 settings all complete now. I do see that I would need to use the FAVORITES to change bands instead of using WSJT-X to do so. That's fine. Incidentally, have you tried WSJT-X Improved Version? It has band buttons and more.

Thanks,
Scott N1IA

Thanks Scott. I do use WSJT-X to change bands on SDRC but I select my preferred span and filter for WSJT-X and that does not change when I call a frequency change from WSJT-X so that works fine for me. But I also have Favourites set up for it too so that I can quickly check for activity without running WSJT-X.

I downloaded latest version of WSJT-X. Did not see any ban buttons, just the usual dropdown list. Maybe I need to enable them somehow? Anyway, academic as it broke Hamlib somehow and I kept getting coms error "Retry" dialogue from WSJT. Messed about with it for quite a while but gave up for now and went back to previous version when it started working again, so not sure what's gone on there except to say I can see from Googling I'm not the only one! Will try and sort it soon as I suspect others with SDRC will also have problems with it. Seems you do not though.

What hardware are you running? All SDR or external radio and SDR receiver?

OK had another go with latest WSJT-X 2.7.0. For some reason I needed to make a couple of changes in the "Radio" settings from the previous version to get it to work with SDRC but all now OK again. I guess they made some changes of some sort in the latest version of Hamlib incorporated with WSJT-X. Anyway, it's all good now.

I can now see that the band buttons that you referred to are not in the regular release version but in 2.7.1 "Improved" version from DG2YCB. I'm not sure if that version is officially sanctioned but I will give it a try anyway.
