I used EasyEDA for the designing. The are associated with LCSC for parts and JLCPCB for boards. I don't know who owns who but it's a booming business and they know what they (Dillon does anyway) are doing (in my opinion).

Which company did you end up using for the PCB? I've been using Seeed Studio, but they have really been slow lately.

OK, "the button has been pushed" and the Gerbers are sent. They still have to accept the Gerber files. Based on DHL shipping experience, the boards should be at my door in 10 working days. The average cost of the two boards plus DHL shipping works out to about $0.12 each. However, that means that they accept the Gerbers and that the boards are correct. I really don't need any more neat 100mm x 100mm coffee cup coasters.

The boards will still have to be cut (on my shear) or snapped apart before use. Now to see about getting some more bulk parts in here and see what the total price will be postpaid, getting some testing done, and figuring out inexpensive payment methods.  

Gary, KJ5VW, is still compiling a spreadsheet of those who expressed an interest and we'll probably post that in the files section soon.

We have plenty of boards coming for the first pass .....320 AGC boards and 280 Click filter boards. 

Looks like these guys WILL DO step and repeat at a reasonable cost so I don't have to do that manually again (bummer of an activity since the part ID's increment).

Re: Removing nano from radiuno #nano #radiuno #ubitx

Hello Art,
I am in VK land so time difference may make this exchange a bit slow due to time differences, but I am happy to help you.

You are almost there, since you have the Arduino IDE installed and the software opened in the IDE.

You need to connect the Arduino to the computer via a mini-USB to standard USB cable.

Before plugging the cable in, you may need to install the driver for the CH40 chip doing the USB communication on the Arduino board. 


Here I assume you are running Windows.

My driver's file I downloaded is called ch341ser.zip and is 187,867bytes long. It should be easily found via Google.

When you plug in the Raduino it will give you a new comm port that is visible in the Arduino IDE in the tools/port section (they typically have high numbers like com12).

Select, it. Then ensure you have board "Arduino Nano" in the Tools/Board field, "ATmega328P old bootloader" in the Tools/Processor field, "AVR mkII" in the Tools/Programmer field.

Now you can compile and upload the program with a CTRL-U.

It should show you the progress in the bottom section of the screen.

All the best,

73, John (VK2ETA)

Rather than loose key information in a long list of messages.....135 ??, I'm going to list all the pertinent info.....schematics, spreadsheets, delivery status, how to order the mini kits, etc in the files section under my call  K5BCQ  That will probably be the easiest to handle.

If you really want to work with through hole parts, you should look at Ion's
AGC board.
May have to fab it yourself using his gerbers, and then order the parts.
Maybe order enough for a few dozen (could cost you an extra $20) and set up
your own kitting business?

You should look at Howard Fidel WB2VXW driver mod. It consists of adding a capacitor across both emitter resistors R87, R88 of Q911 & Q912 and an inductor in series with R86 the collector base resistor. This mod will increase the output on all bands, on 10 meters I’m seeing 4 watts out now. That is with my output on 40 meters set to about 14 watts out.

That's seems to me a lot of power on 80m. I have found about 12w on 80m, a little more than 10w on 40m, 5w on 20m, 2w on 15m and less than 1.5w on 10m. Using a transverter 144/28mhz I made 14 qsos in one hour, I was told that modulation per se was very good but not continuous. In fact my transverter needs about half watt to switch to tx, a level that is not reached at all times during a ssb qso. A compressor would be a nice addon. Any idea for one not terribly expensive?

If you use something like FLdigi to watch the modulation, which can graphically show you the frequency of the modulation, you can probably calibrate pretty accurately.

Using WWV or WWVH for frequency calibration is a bit confusing unless you know
about their modulation scheme.  They transmit carrier with 500 Hz modulation during
part of the even minutes and carrier with 600 Hz modulation during part of the odd
minutes.  Minutes 43 through 52 are un-modulated carrier.  These are the times when

Re: Protoneer Nano-Arm #ubitx

Gary Anderson
 

Also received my Protoneer  in the mail today with a 20 Apr order date. 
I just plugged it in and downloaded / installed the Arduino SAMD board version 1.6.18, running in Arduino 1.8.5
Using the blink demo, I changed to a fast blink rate and confirmed the basics work.

When I get some time, I will first try getting the SlowSoftI2C  working on something.  I have a ADS1115 ADC board.

Of the various versions of Raduino code out there, what do the interested parties think should be the first code to get converted to the Arm M0?
I was thinking either the factory code as a test case or a released and non-Beta version of Ian's code.  I'm heavily leaning to Ian's code, since I think most  Arduino hackers will start with that.

I think many would be interested in a 6m-2m-70cm version. Of course those transverters may work. But I have a 70cm of these transverter and never worked in TX. In the end I gave up and opted for a Kenwood ts-811.

If looking for a compressor, a search on eBay for SSM2167 will produce a few results.

The "Orange board" has been used  a few times and produces good results at around $5 each.

I increased the compression ratio to 4:1 by changing one resistor (instructions on eBay) and it really keeps the average power up.

Memory CW - Island Keyboard by WB9KZY

Straight Key and paddle work. However I wanted something automatic like contest macros. In Linux I could not manage to send correct cw with the Ubitx. In windows was a bit better, not perfect (I was using the DTR port, I have not tried the RTS yet). Btw tonight I tried an old kit called 'Island Keyboard with the optional tube keying output' by WB9KZY and It works perfectly! It does work with an old keyboard not PC. It uses a solid state relay and I suspect this is the key for a neat cw, 73 Franco
