Just for grins, put together a dummy load from a couple of amazon items, an aluminum heatsink & 50 ohm resister (RFP 250N50) & parts laying around. Parts cost, delivered, was < $18 Construction mainly consisted of designing/printing the 3D printed bracket for the SO-239 & drilling and...

I got around to testing a printed "V" antenna base design today. The base was done with M10x1.5 threaded inserts, but I have adapters to permit use of whips with a 3/8-24 thread. This was an initial test print with modification. The current model is more refined. I mounted the base on a...

I did another DC powered charging base, this time for a UV-K5. It is based off the TP5100 lipo charging module. .STL files & source were placed on Printables: https://www.printables.com/model/1268044-uv-k5-dc-charging-base

Just got an AT-6666PRO in & did a initial test on a set of protective "handles" I drew up. They extend far enough to protect the knobs and have a provision for adding "pegs" to elevate the front. Although I have a large format printer that could print them in one piece, I split the model to...

I recently drew up & printed parts for DC powered charging bases for a couple of HT's. Their OEM bases had either broken mounts or were AC only. I did a couple for the BF-888S, mainly due to the OEM base being 110v AC only. The DIY version has a USB-C socket for 5v input. Contacts used...

My G90 came in this week & I got a chance to finish up a little project I started when I ordered it. I needed to finalize some dimensions and do some test fittings that had to wait until the radio was in hand. What I put together is a desk stand with cooling and power distribution. The stand...

I just finished up a new version of components to build a 3D printed Anderson PowerPole distribution box. It differs from the previous versions I've done in that it has a flat profile and is modular. The basic housing framework has slots for "modules". There are modules for holding powerpole...

I put together some handles for a couple of radios. They can be handy with a radio that is not permanently mounted & being used in a temporary fashion. They can provide some front panel protection & elevate the bottom above a flat surface for better cooling & sound from bottom mounted...

I recently acquired an AT-5555N II and downloaded a copy of the QPS5555N_II_2.02 programming software. Most elements are fairly self explanatory, but what is the function of the work group selection? Band use seems obvious but work group not so much. Is it just a way to set up the default...
