1.? You print them.
2.? You coat them after application with very light layers of clear spray paint, like Krylon.
3.? Laser has the advantage of being waterproof, so it's likely a little more foolproof.

Extra space was made to allow front panel controls to avoid the 8-pin
connector.? Since this is a temporary enclosure I added extra space
to make it easier to play with some near future modification ideas.

I would like to know
more about the Decals.? I used to make lots of Test Equipment.
We bought packages of
rub on decals from the electronics parts store.? They had
numbers letters, and common words.
You rubbed them on
with pen or hard tipped object and then coated them (like
clear finger nail polish).
These water decals??
Do you print them or can you get them with words, numbers and
letters?
Do you coat them?
Do I have to worry
about printer, I only have B&W Laser, no inkjets.
Thanks for any info.?
I looked at Amazon?? Some there but not much detail?

I'd just configure the relays in the uBitx for 80m (the 80m LPF will pass 160m too),
then add an external LPF when using the uBitx for 160m.
If you have a separate 160m antenna, there is no loss in convenience.

?Arvo:? ?every mic is different but there are common themes.? ?Lots of mics these days use electret elements which require a load resistor and DC voltage (the Bitx has a resistor and DC source) --- but you'd be wise to LOOK at the schematic of your chosen
mic and ascertain how it is built, what it wants, what the internal technology is (electret, crystal, ceramic, dynamic, internal transistor amplifier, etc) ---? ?
On my Bitx? I specificaly provided dc-coupled output to run the standard electret mic, and then used a small electrolytic capacitor (a few uf) to DC isolate to allow a powered CB-style mic to also be used.? ?
And because I do some digital, I put a wall-mount 8-pin RJ45 female there to which the mic or the soundcard system can connect (and there you need the DC isolation because the soundcard output is a TRANSFORMER and will drag the bitx input DC way to ground.?
? )??
That's ham radio -- look at the circuitry, try to figure it out the best you can, give it a whirl and see if your understanding is correct!!?

Re: uBitx Wireless Memory Management

David,
Thanks for the info.
The Bluetooth LE stack portion of the EPS32S might be the way to go. And your i2c ¡°gap¡± approach is what I used on the ten-tec in the vid.
But controlling from a Browser or voice assistant over WiFi, although a little beyond my comfort level, would be ideal.

Re: Small question about LCD mounting
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.?

Re: uBitx Wireless Memory Management
#ubitx
Many "Arduino compatible" things out there simply mean they work in the IDE - they don't ensure any kind of code compatibility. Any lower level code that's fiddling with registers or making assumptions about an underlying AVR architecture won't work with ESP32. I think for the most part the Raduino code is free of such low level code - you might end up changing things for interrupt handling or possibly the included libraries.
As for the ESP, not a "horror story" really, but prepare to debug many strange crashes on the ESP especially when using the WIFI stack :). For me, I was working on a APRS modem using an ESP32 and never got the WIFI working at the same time as the on-board ADC. Something to do with timers... I forget.?
Personally, I would "gap" a wireless module from the radio control and talk to it over I2C or Serial.
Good luck! Sounds interesting!
David, KM4NKU

I¡¯m thinking of replacing the Radino Arduino with the EPS-32S chip (WiFi and Bluetooth) for memory and memory group creation, editing and recall. The control rf is passed through seams in your uBitx chassis (if you haven¡¯t put copper tape everywhere!).?
?
I¡¯ve never used this chip and I wonder about:
Power consumption, Arduino IDE and code compatibility, rf hash. Or any horror stories.
?
Here is a video of my implementation (using another chip) on a Ten-Tec QRP rig. Vid is only 55 seconds and NO TALKING.
Hmmm. Voice control with google voice assistant?

Re: Small question about LCD mounting
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.?
