I cannot remember all of the frequencies for the bands so I created this reference. Its a small set of cards based on the ARRL band plan chart placed into a stand. I place the stand on the top of my radio and pull the card with the band I'm operating on to the front slot so I can easily see it. Then I know the limits of where to tune my radio and use it.
These are written to show the Extra Class bands but could be easily modified for other classes as needed. I print them all using PETG with 15% infill. To print the colors you need to set filament changes on layers when slicing as follows:
Black - Up to 2mm
White - 2.2mm
Red - 2.4mm
Green - 2.6mm
The author marked this model as their own original creation.
