Amazing, all on single sided board!

Nice...

Hi Colleagues

Bore Lezaic from Montenegro is working on the uBitx PCB designed by Heriberto -CM2KMK- from Havana, Cuba

Here some pictures he(Bore Lezaic) have posted in my FB wall.

Any question regarding uBitx PCB please send to Heriberto Gonzalez Mendoza at cl2kmk@... (please take care with the email address it is slight different to his actual call sign).

NIce looking and simplified using SRA-1 (Hi-Rel)? It is almost equivalent and pin compatible to SBL-1. Only issue is coat and availability of these minicircuits' components. Perhaps Farhan (VU@ESE) aimed at good performance and lower carrier leak using BAT54. His design helps in cost reduction.

All the best.

Excellent.

What I suggest is that the pcb design be made available as a PDF or word file for those who would like to build one.

This applies to all designs if the designer is willing to share them because it makes life a lot easie.

Thanks and regards

Lawrence?

Nice Job, multi-band 4 leg critter

Silly question, When does it appear on HFSigs?

I am not sure that it would make it to hfsigs yet. pcb is a only a small part of the entire job to get it on hfsigs. it took me months to train the 'girls' to figure out the transformers, coils, etc. there are five different windings on the T30-6 toroids, they can easily mix up a 9 turn coil for a 10 turn coil. the logistics are daunting.

Cost escalation can bring manufacturing peace, but that will defeat the whole point. It would be sweet if the board could be delivered at the 100 dollar mark. i would love that very much.

btw, just as a note. there are no restrictions on anyone kitting the ubitx. i hope somebody else does it soon enough. i'd like to buy one too!

?Ask them to use different colored wires for different coils,

?like Green would be 9T and blue would be 10T etc

Board looks nice!
Does the Raduino plug directly into the board with no intervening cables?
Looks like you've got the extra LPF's in place now,?
Is that a single crystal 45mhz first IF filter I see?

I assume the connector to the right of the display is for front panel mike, phones, gain, etc.
Maybe we could cook up a daughterboard that plugs directly in with all such connectors and pots
soldered directly to the daughterboard. ??

Perhaps you could auto-stuff the surface mount parts and sell initial kits with sorted crystals
and some assembly required, such as winding coils and adding through-hole parts. ?
Some scrounging for connectors and such would be fine.
That would give you some experience with the board before committing to full production.

Regarding coil troubles in manufacturing: ?maybe they need an inductance meter on the bench.
A quick measurement of each winding to verify they have the correct coil with leads properly identified
before soldering to the board.? Maybe a jig with an Si5351 plus diode RF probe(s), built specific to?
each coil assembly, instead of the inductance meter.
