Small question about LCD mounting
I used one of the plastic cases from Bangood and cut the opening for the display with a?
coping saw. I made it just a little bit small for the display. I was then able to enlarge and even it out using an exacto knife and sandpaper/file so that it was just big enough to friction-fit the display. I didn't bother to use screws or any sort of glue.? Michael VE3WMB? |

4-40 screws and a 1/8" drill bit.? John On Dec 12, 2017 1:40 PM, <sulu82@...> wrote: Same here. Just a push fit .No screws . |
Michael, nice finished look! What does your wide/narrow switch toggle? I'm guessing you did some hardware mod for a CW filter? On Tue, Dec 12, 2017 at 2:36 PM John McFadden <johnamcf@...> wrote:

David :
The switch controls ?a SotaBeams DSP audio filter module. I have the General Purpose one installed which has a 2.4 Khz SSB filter (WIDE) and a 300 Hz CW filter (Narrow). The switch is actually a three pole switch so the top position bypasses the filter. These little modules work amazingly well and only draw about 30ma of current. I have another one on order for my uBITX. Here is a link for more info : https://www.sotabeams.co.uk/dual-bandwidth-filter-modules-ssb-cw/ Cheers Michael VE3WMB? |
Yes. I would also like to know how you put the lettering on the plastic panel Michael Babineau .

The decals for my BITX40 were done using Ink-Jet Waterslide Decal paper.? The end result is similar to decals that we all probably remember putting on plastic model kits as kids.? I do this for all of my projects and I found that the cheapest way to do this is to buy the paper on eBay from China. What you want is the stuff with the clear (transparent backing) that comes in A4 sizing. There are sources for this stuff in letter size from the US but costs to ship to destinations outside of the US?is expensive. Every ink-jet printer sold in North American can handle A4 sized paper so it doesn't matter.? The procedure is pretty simple. You use your favourite graphic/text editor to create and print a sheet of decals (you want some extras for each decal in case one rips during installation). After printing I recommend letting the ink dry for at least 12 hours. The sheet then gets a?couple of coats of clear Krylon spray to fix it?(remember ink-jet ink is water-soluble) and is allowed to completely dry overnight.? I also spray the panels that the decals will be installed on with a thin coat of clear Krylon as it gives? a better result and makes it less likely that you will tear a decal during installation. Everything has to be very dry before you attempt to install the decals.? The installation procedure simply involves cutting out the decals and immersing them individually in a small bowl of warm water for about 20 seconds. Remove the decal from the water with tweezers and then ?then slide off of the paper backing onto?the panel with the help of a tooth-pick, which can be used to position it. You then carefully blot out the excess water & air bubbles with a tiny piece of paper towel. ?Repeat for all of the decals and then set it aside to thoroughly dry overnight. Once it is very dry you want to spray a couple of very thin coats of clear Krylon?over the top to keep the decals in place. You can print in whatever colours your inkjet printer will support, which unfortunately normally doesn't include white. ? I usually do several prints on plain paper, cutting out the paper decals and? moving them around on the drilled front and rear panels to get an idea of placement and making sure I am happy with the fonts and sizing. The last print is on the actual decal paper, but only once I am satisfied. As I mentioned previously since you have to print a full sheet of decals anyway it is a good idea to replicate individual decals a few times on the sheet so you have spares in case one gets torn during installation. ? Cheers? Michael VE3WMB? P.S. You can get Waterslide Decal Paper with white backing instead of transparent.? This would work on a smoked plexiglass enclosure, however the end result will look like? stickers because of the white backing, which will be visible.? |
I forgot to add that there is one additional step the can be added if you want a very professional-looking result for your water-slide decals. ?After the decals have been installed and before you?
put the clear Krylon coat over the top, you can apply a product to the decals that softens the decal backing material. I am not sure exactly what it is called but it is available at hobby shops. What this does is to pretty much eliminate any visible "seam" at the edge of where you cut out the decal. Once this has dried and has been fixed with clear Krylon the end result is very close to what you would get if the lettering was printed onto the panel? via a silkscreening procedure.? Cheers Michael VE3WMB? |
One of the biggest advantages of using Water-slide decals over some sort of label-maker
is that you can print whatever graphics you want, whereas label-makers are limited in the choice of fonts and generally only print text. ?Here are some photos of another (non Bitx) project that I recently completed. It is a W8TEE (et al) Modular Transceiver from the? March 2016 QST article. I opted to use simple graphics instead of text labels, for a change, to keep the front and rear panels clean-looking. Note that the light angle was bad for these photos and the backing on the decals appears much more visible in the photos than it really is in normal viewing (it looks much better in real life than in these photos).? Cheers Michael VE3WMB? P.S. Before anyone asks ... the red Chinese characters on the front panel are the number 49. This is a tribute to the use of the rockbound Chinese Forty-9er DC 40m Rig (available on eBay for $9) that this project is built around. ?I like to make up a logo for my home-built rigs.? |

Also a company called Microscale makes decal application products. Hobby Lobby used to carry it. Can't get carried away with it. You'll destroy the decal. It does soften it after all.? In modeling you use them to snug down and into panel lines and such. Well if you're a good modeler you do. I mostly just messed them up! LOL! Dan Reynolds -- KB9JLO -- Dan Reynolds -- KB9JLO <>< |
