Why not instead a memory scan (with increased number of memories) or frequency scan capability?
A SWSkeds database import with SWSked  label in the Source field , not custom.
Custom I want to reserve to my own records.
Just to name a few features...

I find the 3D superb because I learnt about Direct3D programming, and education is an important part of ham radio.

 

Also you don’t know if it’ll be useless until it’s written, so a ‘chicken and egg’ situation.

 

The good thing – I now have 3D in my coding armoury for the future.

Francesco,
If you think that was the proper way to request additions to this software iyou are sadly mistaken.
Your expression of gratitude is matched only by your obvious lack of

Mike,

 

When you program with Direct3D 12 it’s quite different – very, very efficient but you’re down inside the innards of DirectX. I’m sure this can be done, I just haven’t determined to very best solution.

Placing a legend on a 3D grid was a problem I had some years ago on a work project. The 2D solution projected to 3D was the one I used and it was not as nasty as I thought.

 

In that instance I was just interested in numbers so I created 1-9 in line graphics looking like an old 7 segment display to limit the overhead. I used an existing 3D library I had already written that projected 2D lines (x1,y1,x2,y2) into 3D (x1,y1,z1,x2,y2,z2) space. This application was to display two orthogonal antenna radiation patterns as a 3D picture, ie it was not a solid just two planes. The user could spin the diagram round in x,y and z with slider controls/mouse. Any of the available libraries seemed massive overkill so I wrote one that did what I wanted and no more. It was done in VB.net and the 3D bit was relatively small at about 500 lines of code. The beauty of doing the legend this way was that used the same classes as the plot itself. This situation is rather different but I would not dismiss the maths as too awful. I met the dreaded “gimbal lock” problem in the rotation controls but I could avoid it by limiting the available spin and having a user return to zero button. Also I had the luxury of being able to plot always in 2D and then let the user spin it around.

 

I have attached a not very good picture of the axis render to give an idea what it looked like.

 

Interestingly I have a similar feeling about the 3D waterfall as I had about the 3D radiation patterns, quite pretty, but how much does it add? In my case our marketing department wanted a killer USP so it had to be done...

Only two thing are missed :

The 3-D scope should have on/at the baseline a frequency-scale and markers ...

and it should be available to switch the mode also between “Fix”-Mode or “Center”-Mode ,

like the same in the 2-D waterfall and/or scope .

Um, isn't nearly every VHF and higher frequency software defined Radio using what amounts to pure transverter technology?

That said, do remember that a 10 meter to 2 meter converter suffers heavily from the fifth harmonic if the 28 MHz signal. It is worst from 28.8 MHz (think typical rtlsdr dongle clock) to 29.2 MHz. A good transverter design is not a trivial exercise.

Re: 3.0.28 Release

Well,

 

Run the 16-bit ADC at 1GHz, nice low-noise pre-amp and some decent software – can’t do much better than that unless you have a DOD contract.

 

I’m loath to spend any money on VHF / UHF at the moment – had only 3 days sporadic-E here on 2m this year, not much tropo to write home about either. DAB+ brings me some good jazz stations and, with luck tropo ducting to France so I can receive their multiplexes.

Well, actually yes. {^_-} If you think about it a transverter is indistinguishable from a normal front end on a multiple conversion superheterodyne design. And it does not matter if the downconverters and IF strips are digital or not. At least digital processes can be FAR cleaner than analog. (And you can perform tricks such as pushing filters through downconverters and decimators. That gives your filtering the equivalent of multiple 0 frequency IFs.)

I tend to take a VERY generic view of radios. One way or another they gotta do a certain set of operations as a minimum. And so far I've not run across good discussions of what the A/D and D/A converters' nonlinear conversions really does in these settings. IMD, yes. But does it setup problems further down the reception chain?)

No. There are some exciting new chips from ‘Asia’ which make DDC affordable for the ham community. Obviously SHF+ will be downconverter-based, but 2m & 70cms can be DDC.

 

There’s an amazing 0 to 6GHz SDR receiver coming this year, I am not allowed to say who is developing it. I am prodding the develops for a companion transmitter.

Um, isn't nearly every VHF and higher frequency software defined Radio using what amounts to pure transverter technology?

That said, do remember that a 10 meter to 2 meter converter suffers heavily from the fifth harmonic if the 28 MHz signal. It is worst from 28.8 MHz (think typical rtlsdr dongle clock) to 29.2 MHz. A good transverter design is not a trivial exercise.

Hi Simon,

 

I thought you might like the attached screenprint, while running the 3D option, all the icons on the screen turned to a microphone icon - No idea why, and when I rebooted the program all was well.

 

New version v3.0.28 is running great, dog biscuit allowance sent via Paypal.

Hi Simon ,
 
...  so far all works very fine and looks nice with version 3.028 , also with 3-D-Scope.
Only two thing are missed :
The 3-D scope should have on/at the baseline a frequency-scale and markers ...
and it should be available to switch the mode also between “Fix”-Mode or “Center”-Mode ,
like the same in the 2-D waterfall and/or scope .

Re: 3.0.28 Release

Well, actually yes. {^_-} If you think about it a transverter is indistinguishable from a normal front end on a multiple conversion superheterodyne design. And it does not matter if the downconverters and IF strips are digital or not. At least digital processes can be FAR cleaner than analog. (And you can perform tricks such as pushing filters through downconverters and decimators. That gives your filtering the equivalent of multiple 0 frequency IFs.)

I tend to take a VERY generic view of radios. One way or another they gotta do a certain set of operations as a minimum. And so far I've not run across good discussions of what the A/D and D/A converters' nonlinear conversions really does in these settings. IMD, yes. But does it setup problems further down the reception chain?)
