Belt Clip - Sporty's JD-200 & SP-400 Aviation Handheld Radios

thingiverse

This is a belt clip for a Sporty's JD-200 and SP-400 handheld aviation COM and NAV radio. Pilots often carry a spare handheld radio in case the electrical system goes out they can still talk, especially in a rented or shared plane. These Sporty's radios also have an OBI to let a pilot use VOR beacons for in flight navigation and also line up with the runway localizer on ILS runways, the SP-400 even does glideslope. Sporty's shop sells a $10 +shipping metal clip accessory for their radios but I am too cheap to bother with that when I might break it off. I want to be able to clip to my headset bag or lower leg cargo pocket more than I need to clip to my belt, also to clip to my collar so the antenna is up if I need the radio in a power outage. Piston planes have magnetos like a lawnmower so even if the power from the alternator and battery is out the spark plugs will still fire and the engine and most instruments will still work though there are no lights, radios, or avionics. Untested design, but should be close enough that if you really need you can just bore out the screw holes or grind no more than a mm of plastic. This might need more plastic on the top side of both the base and clip for the spring to lever against. I also need to print and verify the screw hole placements. Don't forget to acetone/ABS glue the leverage pad to the base if you make this. No warranty, I am not responsible for the loss of your radio or anything which results from that. My radio, an older Sporty's JD-200, has markings that a belt clip assembly requires 2x M3 screws which extend no more than 3mm into the radio, that means no more than 3mm of thread sticking out of the clip assembly. I found this on Thingiverse when listing the belt clip, an external power supply which looks to work with other Sporty's radios including the JD-200, if you like to listen when at home or you work at a FBO. https://www.thingiverse.com/thing:1092186
