<div>Hi All,</div>
<div>Thanks to Phil VK6APH I have discovered the 'pan lock'
feature in cuSDR. Finally I can set the panadapter and
waterfall to monitor say all of the 40m band for example and
tune up and down without the whole display shifting to the
left or right and losing the waterfall history - fantastic for
contests. Well done Hermann! No Tx sadly though.<br>

<div>How difficult would this be to add to PowerSDR VFO A (yes I
know VFO B will sort of do this but its not the same)? I have
no idea. With the new 384k panadapter (which is also
fantastic) it would a superb feature.</div>

That has been on the PowerSDR wish list for a very long time. I
forget the details now, but I had a nice chat with one of the
software developers in Austin and he explained that this is a very
non-trivial enhancement, so don't expect it any time soon.<br></div></blockquote><div><br>mmmh, the implementation of which is just a few lines of code...just shifting frequency digitally. Look at the cuSDR sources, or from the original implementation of cuteSDR, or .... (there are surely other examples!).<br>
