Thanks for the info.Something new for me to try.

It was shipped via DHL on the 12th and I got it today the 14th!!!!!!

I did a card stock mockup of a front panel design and I can make it fitl? ?The large black circle on the top right is
the outline of a 1.5" knob centered on the encoder (white? rounded rectangle).? The smaller black circle below
it is the volume control.? The large white circle in the upper left represents the mounting nut for a 1/4", switching
jack for the headphones and the smaller circle below is the 3.5mm TRRS mike jack.? I will install an APLOP
board and I have not decided if I will install the key jack (not a CW operator) or where.

the picture is for demo only. Notice the arduino board in behind is not connected to anything but the display. I suspect Al is using the default firmware for display purposes only so missing all the software mods. This method is basically plug n play - no soldering or rework. I like easy!?
If you want to melt some solder then flip the LM7805 5V regulator to the back side so a heatsink can be easily added. Runs alot cooler now.

Try Googling "Laser Waterslide decal paper". ?

It sounds like what you were using for labelling instrumentation was more like "Letraset"
or something similar. ?Waterslide decals are more typically used for plastic model planes etc.?

As Arvo suggests, there are some advantages to using Laser printed decals as the toner
is effectively baked-on rather than sprayed with a water-soluble ink (if you have ever gotten
an ink-jet page wet after printing you know what I mean). ?With some Laser Waterslide decal paper
there is no need to "fix" the printed decals with something Krylon. ?

Just be aware the you will need to use a Laser printer specific version of the paper (i.e. something?
that specifically says it is for use with Laser printers) otherwise the heat from the printer may
damage the decals and possibly your printer.?

It's a mess, but I have my ?BITX working now.

It's a "bunch of wires" but I'm glad to see you have it
fired up and working. I just received a confirmation
that mine has shipped, but I didn't go for DHL so
I'm sure it will be a few weeks.

The encoder appears to be optical (?) as there is
feel of detents when tuning.

Perhaps Ashhar can confirm that. I could be wrong, but
I would have assumed it was mechanical.

Those are some cool knobs.

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.

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!!?

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.

Those look very nice!? Thank you for sharing about the decal edge spray!

Does the PC or cell phone mic need any special circuitry beyond what's already in the BITX40 or ?BitX?

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

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.?

I wouldn't bother them. They must be overwhelmed.... this is the
response I received:

"Hopefully, we will be able to include in the first run before
Christmas. The tracking details will be updated on the Paypal
Transaction after the shipment is done. "
