SHOWCASE

 

Wow, check out these works of art!  Getting any ideas for modifying or accessorizing your own Old Friend Transceiver?  I sure am!

  1. Ken WA4MNT ... Ken is right on top of things with us by already adding the volume control, and he's a step ahead of us by adding one of his own magnetically-attached paddles to the outside of his custom case, making for a more portable rig.

    Ken describes ... "As per the George (N2APB) post, I added the volume control. Both my earbuds and headphones were very loud on strong signals, and this is a welcome modification well worth the effort to anyone experiencing the same issues. I used a 9mm vertical Tayda 50K trimmer pot (A-1869) with the shaft extended through the case cover, and I secured the pot with some small dabs of epoxy on the inside of the cover."

    What a fabulous homebrew enclosure Ken!  // Ken's has lots of cool QRP accessories for sale on his web page at QRPBuilder.com

    During the Christmas season, I enjoy building radio kits and finally got to use the chassis I designed in November. I obtained a perfect size, bare chassis from Ebay and designed it to use my OT-30 radio in it.

    I started by making drawings using Corel Draw CAD software and laid out the front and back panels complete with all the lettering and hole placements. The design was then printed onto clear plastic to make a "positive" photo stencil for the silkscreen production. 

    I first drilled all my holes in the chassis and then painted it flat black. It was now ready for the silkscreen process.

    Once the silkscreen was produced, it was used to print the lettering on the chassis sides.

    After printing, a thin coat of polyurethane was applied to finish it. 

    During Christmas, I got the PWB all soldered up and was ready to start installation into my chassis.

    I mounted the switch and pot/switch, encoder and display module and finally the PWB.

    I wanted to make the PWB removable with no loose wires so, I used DuPont connectors and header pins to connect between the chassis and PWB.
