Oh, one more thing. If you do tackle making a larger icon set, it is important that all background pixels be pure white (RGB(255,255,255)). The program uses this as the transparency color when copying the icons to the screen.

What format are you using for the icons?
Perhaps you could send me a copy and I could start working on a larger
set for you?
I just posted APRSISZoom.zip that contains a zoomed icons for screens larger than 320 pixels. As your scale gets smaller than 2 miles, the icons will begin to expand (the actual scale code is listed below for C programmers). See if they look ok on your higher resolution screen before diving into the editor.
But, just to cover all bases, I've also included the .BMP files from which the icons are drawn. The icons are clipped out of these composite pictures automatically by the program. My intention is to allow users to specify external Icon files as well, if they ever want to customize them. For that reason, I'd really rather not build the support for two sizes of icons unless it is visually necessary.
Of course, if you do take the time to expand these BMPs and clean them up manually, I could always make the larger set the standard and scale them down on smaller screens!
The program assumes that the icons are laid out in a 16x6 grid. It divides the image width and height by 16 and 6 to get the actual icon size. It then assumes a 2 pixel border all around. In the end, it gets a 17x17 pixel icon out of a 21x21 repeating square.
Let me know how the expanded icons look on your screen. They didn't actually look as bad as I thought they might when I previewed them here (not on a phone screen, though!)

PS. Here's the current brute-force code that does icon scaling. I want to make it a more dynamic scale based on circle size, device resolution, and the scale of the screen, but, as I mentioned before, I haven't worked out the details yet. It's striking a balance between recognizability and showing lots of stations in a small area.
Of course, if you click on a station icon, the popup does tell you what the icon is supposed to be!
if (scale >= 128)
{ Mult = 1; Div = 2;
} else if (scale >= 64)
{ Mult = 2; Div = 3;
} else if (scale >= 32)
{ Mult = 3; Div = 4;
} else if (width < 320) /* Drop out all 320x240 screens */
{ Mult = 1; Div = 1;
} else if (scale >= 8) /* Bigger screens begin to magnify */
{ Mult = 1; Div = 1;
} else if (scale >= 2)
{ Mult = 5; Div = 4;
} else if (scale >= 0.5)
{ Mult = 6; Div = 4;
} else if (scale >= 0.125)
{ Mult = 7; Div = 4;
} else
{ Mult = 2; Div = 1;
}
