Re: Determine best values of VFO_A and VFO_B

Bob Shaw
 

Thank you Ralph for your reply. I have MASTER_CAL as 92 68 00 00 from an attempt to calibrate by zero-beating an AM broadcast station. Is there any procedure to get new values for LSB_CAL, USB_CAL and SIDE_TONE that you know of? I do have a GSP referenced  RF signal generator.  Too bad there wasn't a warning about these values with the uBitX, or perhaps these values printed on each board, since they are so important yet vulnerable to loss.     Bob VA7SU

Re: NEXTION DISPLAY UPDATES For KD8CEC ver 1.094 up

Jim Sheldon
 

I enlarged the window of one of my earlier uBITX rigs (that had been installed in a Circuit Specialists extruded aluminum case) to fit the 3.2 inch Enhanced Nextion. Originally I had used a 4 line by 20 character I2C LCD display and I was able to make the Nextion fit in that case by seriously enlarging the opening.  It isn't as neat as if I would have been able to start with a blank panel, but I have a Bezel on order (should be here today) that I hope will cover most of the old screw holes and then I can re-label the jacks & controls.

I got complacent when I wired it originally and was off on the blue "TX" wire from the display to Raduino display socket by 1 pin.  I had the Nextion's TX going to pin 5 (ground) rather than pin 4 (RST) and it displayed everything just fine but would not (of course) command the rig.  Once I got my head removed from a dark place and wired it correctly (LOL) it now works really well. 

I had to go back and re-read Ian's info on the Manager program and do some configuring (still more to do, but I'm on the road now) to get it running smoothly.  Hopefully the new Bezel will help me make it look as nice as the original did with the 4 X 20 display with it's original bezel.  The color Nextion will definitely spiff it up quite a bit with a cleaned up front panel.  Here's a couple pix of the work in progress. Even with the old, vacated holes in the panel it still doesn't look too bad.

Re: CEC firmware with RadI2Cino board? #ubitx #firmware #radiuno

Jim Sheldon
 

Jeff,
We haven't had the time to attempt getting CEC software to work on the RadI2Cino.  It's different in hardware than the original Raduino enough that We'd have to re-work a lot of Ian's CEC code to make it work and we'd rather not modify his code as that would make US responsible for maintaining updates to it and also, it would eventually cause it to diverge from Ian's original code to the point it would not even resemble the good work that Ian has done.  We don't want to have that happen. 

If Ian wants to write code that will work on the RadI2Cino, all he has to do is email me (w0eb (at) cox dot net) and I'll gladly send him at no charge, a wired and tested RadI2Cino board so that he will have something to use as a test for his code.

That's all I can really do at this time.  That offer has been extended before (a long time ago) but Ian has never responded.  The offer remains open.

Re: Lousy Band Conditions #ubitx

 

Doug,

We are experiencing a solar storm right now and band conditions are bad but not completely gone. Yesterday I threw a cheapo 10 meter rig in my car and a Mag mount on the roof and worked a special event station at the Jet Propulsion Laboratory at NASA in the LA area of southern California on 28.400 while on my way to Dr's appointment. About two hours later I could still hear the guy calling CQ, This on a paltry 7 watts out. When I got home I checked into the Noon Time Net on 7.285.5 on the west coast of the US on 5 watts, got a 57 signal report. Even later in the day I checked into the Maritime net on 14.300 using my FT-817ND running 5 watts, and last night I checked into the YL System net on 7.245 using my uBitx and a EFHW antenna laying on top of my roof. So, while the band does indeed suck it's not impossible to make contacts. Just keep trying, it will get better. BTW, I strictly run QRP.

Having the si5351 on the main board is particularly nice because it keeps the RF traces shorter.  The Arduino on the mother board makes less sense since everyone seems to be modifying that part of the radio as their first step. I like the whole concept though…

That is a very nice layout. I'm torn though because I really like the ease of soldering SMD parts, it is much faster, however I like having the si5351 and Arduino onboard. This would make a nice uBitx with a Nextion display.

Lousy Band Conditions #ubitx

Gwen Patton
 

I had luck enough to make a couple of contacts last weekend, but since then the bands seem to have dug a hole, crawled in, and pulled the hole in behind them. I can't hear *anything* out there except for a few squeals of heterodyne and a lot of hash. Even if my antenna was a two-foot piece of rebar, I'd expect to at least HEAR things even if I couldn't get out more than a block, but I'm not hearing diddly.

So my question is, did I blow out the front end or something? I checked the band conditions and last night they were practically zero across the board. I think 30 had a "4" or something, but the rest were flat at the bottom. I suppose the website could be broken, too, so I'm still going to ask if anyone else has been hearing anything worth mentioning, or have I built a wonderful radio and some nice antennage just in time for the bands to die like a squirrel on a six-lane highway?

Never fails. If I buy a raffle ticket, the Monsignor wins the Cadillac.

Actually, once you fix the broken line, the code should work. However, let's make sure the Nano is getting the compiled code. Try this:

Load the Arduino IDE
Plug the USB connector into the Nano
Check to make sure the Arduino Nano is selected (Tools --> Board)
Check to make sure a COM port is assigned to the Nano (Tools --> Port)
    These last 2 steps must be set to go any further
Load the Blink program (File --> Examples -->01.Basics --> Blink)
Compile/upload Blink sketch

If you can do this and the Nano red LED blinks in a 1 second rhythm, you know your Nano is good. Assuming that all is well, then try:

Load the LCD Hello World program (File --> Examples --> LiquidCrystal --> Hello World). Note that this program may be pretty far down the list.
Compile/upload the Hello World sketch.

If this works, then I don't know why the Bitx code doesn't work. If this does not work, then start looking for some kind of wiring/connection error between the Bitx board and the Raduino board.

Elmar,
None of us were born knowing how to do this.  I will try to explain with more detail to see if we can get you through this.  Let us first see if your computer is recognizing the nano.  This will help determine if you have the correct driver.

First go to your device manager.  In Windows 7 go to control panel, then systems and security, and finally device manager.  Most likely you will have one of the two situations described below.

Find a heading labeled Ports (COM & LPT).  Do you see Arduino Nano listed?  If so, write down the port number shown after it.
If you did find the Nano in that section you have the driver.  Now go to the Arduino IDE (the program you installed to compile and load sketches) and check the following under the Tools tab at the top:  For board make sure it shows Arduino Nano, select it from the list by clicking the arrow.  For port make sure it shows the port number you found in your device manager.  Once you have the board and port selected you should be able to upload the sketch.

If in your device manager the Nano does not show up under ports it is probably under Other Devices.  If that is the case you do need to install the driver.  That is also a relatively easy step but that will be for another post if you need it.

The existing filter can be used to make one for either 40/30m or 30/20m.  You cannot cover
40 and 20m with the same filter as the 40M harmonics fall in or near 20M.   Of course
external switched filter is easy to do.

The 13.56mhz is generally used for heating and other processes allowed in the ISM band.
Those less than 100W amps are likely used as drivers for KW sized (induction heating
and sputtering).  As a result linearity is not a factor and class B or C is often the case.
