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…

Peter,

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.

what mode?  what bands?
Lately I've been working mostly digital on 30m and 20m with a little 17m and 15m sprinkled in for variety because I can do that and work my day job.  While all the bands do seem worse than a month or so ago they are far from dead.

Lousy Band Conditions #ubitx

Gwen Patton <ardrhi@...>
 

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.

.Jack,
First, upload Raduino software v 1.27.7 how is described in github was
Not possible because I can not select the port. (Win7 and notebook) why.?.?
With win10 on my sons pc it was no problem.
Now I have fixed the hardware and hope only the nano board was killed.
Shame on me old guy.
Thanks again

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.

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.

I forgot about that possibility. Some old Nanos could have been set with the old bootloader and they are not backwards compatible. If he still has problems, that might be something to try.

Re: Inexpensive eBay Amplifier Kits

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.

This one features a built-in LPF, which seems unusual - but really convenient. The provided LPF is for 13.56 MHz, but retuning for a ham band seems fairly simple. I have not had time yet to built this kit, but I have contacted the maker a couple of times and they seem responsive.

That said, I think getting them to provide a different filter will be a long, drawn out process, and not in keeping with a $20 kit. The 13.56 MHz filter is not far from what's needed for 40, 30, or 20 meters, so the provided toroids could likely be used.

Hi Allard!
Thank you for the fast response. 
Yes, I did adjust LSB from 180 ppm to 90 ppm and USB from default to 1310 Have.
Also changed the LSB drive level to 2 mA, frequency span to 100 KHz and scan interval from default to 7.150 - 7.250 MHz. As before, after each change I pressed the FB to go back to settings. Once all these changes are in place the radio works as it should until I power down. At the next power up it loads again the factory settings.
I went and modified the factory settings in the sketch, so I am left with the annoying issue of starting with VFO A = VFO B = 7.125 MHz and the message.
I can probably go and change those things too, but I would like to have the radio remember where I left when power down.
