Re: AE7EU Top Level PCB Mod

Diver Martin <diver.martin@...>
 

Willy,

Unsure.  I haven't ever had anything made in china before.  The only experiences I've had with china manufacturing is from others experience, which usually involves 'tread carefully, for there are counterfeit components _EVERYWHERE_'.  

What little I know, typically they want a larger volume of PCB's to be made, like more 1k units, instead of 100 as I was originally planning.

100% of my PCB experience is with US-based manufacturing for one-off low-volume specialty stuff, or where I pass a design along to other people who actually go to market with it (or don't, as plenty of cases go).

I want to simplify some of the parts as well to have them be bigger footprints to simplify replacement if necessary... Sadly, Si5351A's are MSOP10's, and the SSM2617 is also MSOP10.  I might try to find an SOIC8 mic amp to replace the SSM2617 (which I mostly decided to try as something different from what everyone else was doing with the MAX8914).  

Gotta get everything else working first though :)

In any case, a revB is inevitable.  In my many many many years of PCB design, I've had a new design work exactly right the first time it was powered up happen exactly once in my life.  It was quite a time for celebration... (that board/product is still in use today too no less!)

Partial kit is about the only way I could sell it.  A full kit, toroids wound and installed, would simply cost too much, I don't think anyone would go for it.  

Right now, if everything works out, there are a few options.

1) Release the board files, schematic, design files/gerbers, BoM and let someone in china clone it, walk away.
2) Same as #1, but just sell bare PCB's.
3) Sell PCB's with all SMT components installed, and a baggie of TH parts, toroids, and couple feet of magnet wire.
4) Sell the entire thing fully assembled ($$$).

4 is unlikely to happen, period.  I would rather redesign the entire system and include the uBitx portion with the mods.  3 is possible, but it'd have to be done on kickstarter or something (5% overhead there), simply because I'm not willing to risk the $10k on a build of 100 boards, 2 is just work without any real benefit, almost the same as #1.

3 & 4 both will have board files/etc released, but not until after the first round ships out.

That looks really nice and thank you for putting in so much work!

Have you considered a partial kit?  I’ve seen a few where all of the SMD parts come mounted with everything else being through-hole.  That would both cut down on the assembly costs and avoid SMD construction for those who don’t want to do it.

Also, I am very interested in this and would order a board or partial kit.

Re: Creating Gerber files for pcb construction

August Johnson
 

I've used ALLPCB http://www.allpcb.com/ and they've had great quality too. Same thing with extra boards, I ordered 5 and they shipped 8. Sots of other people have the same thing with the quantity. I suspect it has to do with what they can fit on the panel size they make. If the have extra space, why waste it if they can fit something in?

Gordon,

I'm very curious about the jclpcb order you made.  How is the PCB quality?  That's a vendor I wanted to try, but haven't gotten around to.  They offer many of the same features as my current pcb house in china (DFRobot) but at about half the cost.  Are the boards pictured from jcl or pcbway?

This is all new to me.   Soldered in header sockets.   Wished I'da thought of that for ALL the i/o connections.

Found at least one error so far -- forgot to ground pin 5 of the LCD display.   Have not soldered in the op amp portion but got the LCD working (after adding little ground wire) and verified that the Adafruit Si5351 is bring controlled --- communications receiver hears  it right where I send its frequency to.

This so SO cool.....

Can't believe how much this forum has taught me in just a few weeks.
This is going to be huge for our local ARES group.   Loads of skills they can learn.

Re: Creating Gerber files for pcb construction

Gordon Gibby <ggibby@...>
 

First set of boards arrived today -- not sure why they shipped me TEN boards, I only ordered five.
This is all new to me. Soldered in header sockets. Wished I'da thought of that for ALL the i/o connections.

Found at least one error so far -- forgot to ground pin 5 of the LCD display. Have not soldered in the op amp portion but got the LCD working (after adding little ground wire) and verified that the Adafruit Si5351 is bring controlled --- communications receiver hears it right where I send its frequency to.

This so SO cool.....

Can't believe how much this forum has taught me in just a few weeks.
This is going to be huge for our local ARES group. Loads of skills they can learn.

Gordon

Thanks for yet another great suggestion.


I have now created a "flying jumpers" breadboard version using a couple of different resistive bridge designs --- the K6BEZ design driven by the Si5351 directly didn't produce enough voltage to make the reverse measurement accurate and I gave up after several hours on that. Would need to add an amplification stage I believe... The easy swr indicator kit from https://urldefense.proofpoint.com/v2/url?u=http-3A__www.qrpkits.com_ezseries.html-23ezswr&d=DwIFaQ&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=3ELgZgmTnPzGsfvQxkd1S_2NGLYM8sHTxVCQKFxhVXQ&m=E2shNumHkU2z89FEz9fB1rmv1B9-9CwkXYgBQ56sX18&s=wATr3kl2cd5RzPMIGfxbDzykiABvusgbH-fnLXPAkSA&e=<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.qrpkits.com_ezseries.html-23ezswr&d=DwMFAw&c=pZJPUDQ3SB9JplYbifm4nt2lEVG5pWx2KikqINpWlZM&r=3ELgZgmTnPzGsfvQxkd1S_2NGLYM8sHTxVCQKFxhVXQ&m=McWMTsaWY88BIHjI9RhDX8BXq0BroHl6MaH6P7zGTVo&s=iOg3ff6bkbrqV9BQbMsupWJHkEUhFqFcHTVOepLM0YM&e=> (no LED, just take the rectified voltage and run into an op amp with a gain of about 6) produced a voltage that seemed to work. My circuit is sorta haywire (with egloo jumpers everywhere) and the pcb version would be FAR MORE STABLE but I'm able to measure shorts, 25 ohm, 50 ohm, 100 ohm, 220 ohm and open circuit and get "sorta close SWR" measurements at frequencies up to maybe 30 MHz. There is so much haywiredness to the breadboard that I can't make any better observations at the moment. The PCB should be a ton more mechanically stable. Earlier today I put it on a real antenna and it did find the resonance.


A friend is working on the "single meter" SWR version using a toroidial swr measurement head (which I also have built and should also work). The goal there is to emulate the $129 LDG big meter display of SWR..... The pcb that I cranked out (and now being built in China, fingers crossed!) should work with both. (2 different inputs).


You folks are a lot brighter at this stuff than I am but it has been a ton of fun just getting this much to work! I think this is going to be a great building project for our ARES group.

I have just received 10 boards for a mere $2 total, including DHL shipping. Note the there is a sixe limit of 100mmx100mm, and two layers, green solder resist and 1.6mm material.

This offer I think is limited to your initial order. A subsequent set of 3 boards, 10 copies each, cost me $29, including shipping.

They are the ones who do the purple PCBs which look really great and also pretty cheap, only a few dollars (around $9.50) for three 35mm x 35mm boards with shipping included.

Re: AE7EU Top Level PCB Mod

Diver Martin <diver.martin@...>
 

I'm actually changing some components to through-hole, simply because they're cheaper, and it would save some assembly cost on the SMT side to let it be a kit.

I want to simplify some of the parts as well to have them be bigger footprints to simplify replacement if necessary... Sadly, Si5351A's are MSOP10's, and the SSM2617 is also MSOP10.  I might try to find an SOIC8 mic amp to replace the SSM2617 (which I mostly decided to try as something different from what everyone else was doing with the MAX8914).  

Gotta get everything else working first though :)

Richard:  A top level mod PCB that's designed to be a solderless add-on to make things clean mechanically, and add a bunch of useful features.

In any case, a revB is inevitable.  In my many many many years of PCB design, I've had a new design work exactly right the first time it was powered up happen exactly once in my life.  It was quite a time for celebration... (that board/product is still in use today too no less!)

Have you considered a partial kit?  I’ve seen a few where all of the SMD parts come mounted with everything else being through-hole.  That would both cut down on the assembly costs and avoid SMD construction for those who don’t want to do it.

Also, I am very interested in this and would order a board or partial kit.

Re: BitX40 voltage booster implementation

Clark Martin
 

One thing to watch out for with these type of converters.  I have one where the -input and -output are not wired straight through, it has a current sense resistor in between.  It won’t work for this application as you need to have a common “-“ between input and output.  If you just short them together it willl, at the least, render the current limit inoperative.  At worse, it will mess up the inverting operation and/or regulation.

I’ve only seen this in one converter but it’s worth verifying before you wire it up.

I had planned to include a switchable voltage booster in my BitX40 build to offer a choice of either 5w or 20w when external power permits by providing either 12v or 24v to the PA power line. I plan to use one of these:

I am interested in if others have already implemented this. Some choices I see:
1. Run 12v power to the voltage booster whenever rig power is on, switch the PA to either 12v or 24v. (booster always on, added load?)
2. Wire the output of the booster to the PA power line, but switch 12v to either the PA line or the input of the booster (booster output capable of having voltage applied when input is zero?)

The booster notes just say the output must be higher than the input, but the allowable load specs look OK for SSB.

I am also working on getting 4X the heat sink on the PA transistor.

If you made it through hole as much as possible I’d go for 2 nd option.

Partial kit is about the only way I could sell it.  A full kit, toroids wound and installed, would simply cost too much, I don't think anyone would go for it.  

Right now, if everything works out, there are a few options.

1) Release the board files, schematic, design files/gerbers, BoM and let someone in china clone it, walk away.
2) Same as #1, but just sell bare PCB's.
3) Sell PCB's with all SMT components installed, and a baggie of TH parts, toroids, and couple feet of magnet wire.
4) Sell the entire thing fully assembled ($$$).

4 is unlikely to happen, period.  I would rather redesign the entire system and include the uBitx portion with the mods.  3 is possible, but it'd have to be done on kickstarter or something (5% overhead there), simply because I'm not willing to risk the $10k on a build of 100 boards, 2 is just work without any real benefit, almost the same as #1.

3 & 4 both will have board files/etc released, but not until after the first round ships out.

Re: Perfect speaker grill

Should have said that I print out template in PowerPoint and a fix before drilling and cutting. Use a good center punch to start drill bit with hole saw, lesson learned hard way.

Re: #ubitx-help Strong Audio Tones in and outside audio receive passband #ubitx-help

James Lawrie
 

Hello,

Get good quality braid and use extra flux. I have done this to several shields and clones, use toothpick to put a little extra flux along pins and use a 40 watt iron. I start with a inch of braid along pins place iron on braid when solder starts to melt I slowly pull braid towards me while moving iron away. 

Usually works first time round and when done use alcohol to cleanup mess just don’t hold iron in one spot to long the plastic and pins can separate. It’s kinda a skill you have to learn but a little extra flux pull melted solder all the way through the hole.

I will check the frequencies of the Arduino and BFO with another transceiver.

I have tried to move cables around but this had no influence on the tones.

Please note that the strongest tone is at 5,426Hz and with more up to 15KHz. So if I go the audio filter way it will have to be pretty steep I suspect.

In desperation I have thought of cutting the traces of the BFO line and one of the two other oscillators and wire swap them around, then changing the sketch accordingly. Would this prove/disprove a coupling issue?

I could buy another Raduino, my only issue is then what if this is on the main board?

So if the frequency test does not show anything out of the ordinary I will buy a header-less Arduino Nano and attempt the swap.

How do you de-solder the arduino? Is a de-soldering braid effective?

To Bill: I used "Spectrum Analyzer"  from Rasberrywood (the free version seems fine for radio audio analysis).

All the best,

Weird that you have a range of frequencies between 5khz and 15khz, I would expect a single tone.
Will be interesting to know if you hear some warble when listening to the 16mhz Nano and the 12mhz bfo.

I doubt switching the clk0 bfo out of the si5351 with one of the other si5351 outputs would help.

You might try wrapping most of the Raduino and display in insulating tape and then tinfoil
to keep the Nano's 16mhz from radiating.
But leave the LM7805 regulator sticking out the side cuz it needs airflow to keep cool 

Ultimately, I think we may need either better shielding, or move the 16mhz clock frequency
of the Raduino to something else.  We've heard from two with this problem, are there others?

Pretty consistent info from all builders; I haven’t built up my uBitx yet because of this issue; looking at alternative PA drivers.  Good news is that my Bitx40 is working well despite a noisy receiver;
