The March 2004 issue of QST has an article on rescaling and customizing meter faces. This is an excellent article, and I recommend reading it before you customize your meter. This section illustrates my experiences with creating a new scale for a meter that I’m using in a homebrew receiver.
The first picture is a meter that I found at a hamfest. It was probably used in a CB transceiver, as it has scale for power output, modulation percentage, and signal strength. I just needed to indicate signal strength.
In order to create a new scale, I removed the scale of a Hammarlund HQ-170 receiver and placed it on a flatbed scanner. I scanned this image into a graphics program (in this case, Adobe Elements Version 2.0).
I cleaned up the image and added red coloring for signals above S-9
