Re: Support for R-666 Dragonfly SDR - Update
As long as Moore's Law holds true, the number of semiconductors on an IC doubles every two years, our electronic toys will be "obsolete" in a couple of years.

Re: Memory channel highlighted
Francesco, for quite a while I was in favour of this proposal (that must have come up before).
There is an interesting similarity between Memories slots and Receivers under the Receive menu:

That is a time honored technique. For example look up "Madman Muntz". Muntz TVs were cheap. NOBODY ever accused them of being quality products.

Re: Memory channel highlighted
Oops - mea culpa - I misread your original message. You are speaking of the memories panel. Now, if you make changes to the memory selection is it still your original memory selection?

Re: Memory channel highlighted
In the matrix the highlighted channel is very obvious and has nothing to do with the pointer. I see it is equally obvious with the receive pane. The region within the receive bandwidth

This is getting like the early days of personal computers. A new and better one every month or two. Gets expensive and you always hope this is the one but it isn’t. Eventually they get so good it

Both the 666 and 888 get brief mentions in this months RadioUser mag. Also half a page on the Polish-made Silphase R1. This is an SDR with knobs and a 5” screen, 16bit ADC, DSP, four (!) internal

Re: Memory channel highlighted
Yes,but if you move the pointer the default color returns.
I have requested the colour of the selected memory button stays steady.
This way, if you move it on the screeen you knos always which channel

Ah,
Interesting. This will affect Doppler of course, I’m surprised at the result.
