I recently simplified my desktop removing NaP3 and reverting back to primarily DXL applications.? I had been using the band change buttons on NaP3 versus the band change stepping function on the front of the K3s.? ? I began using the band change buttons located on the bottom of the Commander Bandspread window.? ?

?

I noted an odd behavior.? ?When using the band change buttons on Commander Bandspread, when you tune to a frequency then change bands, when you return to the original band, the radio reverts to a different frequency that where it was when it left that band.? ?I found that annoying, as I often listen to a particular frequency on a band, change bands to see if I can hear a station spotted on RBN, only to return to the original band/frequency to continue what I was doing.? ?

?

I inquired of Dave about the process and was advised that Commander Bandspread will not set the band stack if there is a band change after establishing a frequency on the first band.? ?The program was, in fact, designed to do just that.? ?I found that an odd behavior.? ? Why would any operator not want to return to the same frequency on any particular band when they returned to that band from someplace else.

?

Lacking alternative, I set up band change buttons in the Commander User Defined Commands using the BN function from Elecraft Programmers Guide.? ?They work perfectly, setting the bandstack when the defined dwell time has expired.? ?The band change buttons consume a lot of User Defined button real estate, but work well.

+ In the original Band Stack implementation, any frequency change that occurs after the specified dwell time is satisfied would result in the current frequency being pushed onto the current band's stack before changing frequency.

+ Many years ago, it was suggested that changing frequency by clicking one of the Bandspread tab's Band buttons (or the Spectrum-Waterfall window's Band buttons) should not push the current frequency onto the current band's stack before changing frequency to the most recent frequency on the newly-selected band. I don't recall the discussion that led to this decision, but I was persuaded at the time.

+ As Don points out, this means that if you've been on 20m frequency X for longer than the dwell time and click the Bandspread window's 40m band button, when you subsequently click its 20m band button, you will not return to 20m frequency X; you will return to the 20m frequency you were using before you QSY'd to X.

+ I'm not comfortable with unilaterally reversing a change made long ago after discussion here, so I suggest to Don that he post a description of the situation here.
