I am sure a bilingual document re the V6 will be useful to someone, maybe many and create more interest with Spanish speakers. Thanks, I'll also take a look at it.

Hola,

he subido un pequeño documento PDF con la descripción del proyecto. https://github.com/ramonlh/ubitx32/tree/master/doc

El estado actual es que las funciones básicas están en funcionamiento. No funcionan IFS ni ATT.

Las cosas que tengo que hacer de forma inmediata:
  • Completar las funciones que faltan: IFS y ATT.
  • Completar las páginas web faltantes.
  • Probar CW en transmisión.
Como explico en el documento, el desarrollo está hecho con UECIDE y no sé si compilará con Arduino IDE. UECIDE es sencillo y mucho más rápido al compilar. Si alguien está interesado en compilarlo estoy a su disposición.

More has to do with whether or not there is arcing in that particular powerline. If there is, you can be an eighth of a mile away and still have tremendous interference.  if there isn’t, you should be fine but you always want to be far enough away that if a wire breaks there’s no chance of contact.  And that is really serious!!

Works perfectly thanks for the info and the link to the TFT file/download locally.

Anyone else having issues downloading from the ubitx.net site.  When I try and download I get server restriction on all downloads.

Anyone have this TFT by chance?

Ok I’ll try to get the antenna up higher, I’ll need to get a telescoping mast first though before I can try that, I’ll probably be ordering one soon

Re: uBitX on CW #v6

Jerry Robinson <k4jer@...>
 

Hey Markus,  I am the "friend" that Vic is referring to.  I have made CW contacts on all but the 15 meter band with my V6.  I am presently using a keyer (a Pico Keyer that I built).  You must, as Vic suggested, tell the V6 what type of keying you want.  If you want to use a keyer go to "Cw Setup" then go to "Keyer Type" then choose "Handkey".  When this is done you can use your keyer.  The hookup for this operation is straight forward -- no surprises, etc.  Further, as Vic said the V6 is not a perfect CW radio -- full QSK would be an improvement, for example -- but with it you should be able to make contacts.  Of course, antenna and band conditions are important considerations with the V6 or another QRP operation.  After Vic installed Reed's sketch on my V6 all I had to do was adjust the "Tx to Rx Delay".

Re: uBitX on CW #v6

Vic WA4THR
 

Hello Markus. Yes, my friend has been able to use his V6 on CW now and while not a perfect CW radio, it does work. Your issue sounds like you may have the plug wired incorrectly or need to select the type of keying you want to use from the menu. For example, if you are still set for an internal keyer, but connect a straight key, the uBitX will try to send a string of dits or dahs whenever the key is pressed. What type of key are you using, how is the plug wired, and what keyer type is selected in the set up menu?

Re: uBITX V6 CW Keyer #ubitxcw #ubitx #cw

Aaron,
I believe that the v6 comes with the Iambic keyer enabled.  In the setup menu, there should be an option to set it to a straight key.  Try that and see if it works.

NOTE: I do not have a v6, so I cannot verify the menu settings.

Re: uBITX V6 CW Keyer #ubitxcw #ubitx #cw

Bob Lunsford
 

The keyer's output should look like a simple straight key to the V6. You should be able to just run a cable to the key input from the keyer's output. If this does not work, then you may need to get feedback from others who are doing same thing.

Oh the keyer is a homebrew CW Keyboard (I have nerve damage and can't send CW) When I plug in a set of paddles it works as is should.

If you don't want to make a cable with the power connector, most big truck stops carry a cable designed to go from a cigarette lighter jack to a small TV, etc.  Just check to make sure the center conductor is positive. Many small power supplies like the ones sold by MFJ have the cig lighter jack on front panel and some portable jumper boxes sold for starting cars have the jack on them, too. Otherwise, some Elmer could show you. The center pin is positive, the shell is negative.

Re: uBitx V6 20M band problem #ubitxv6 #antennas

Evan Hand
 

belthur,

One other thought, The RF could be coming in through the mic cord.  A snap-on ferrite and 0.01 uF bypass caps on the input to the ubitx could help if that is the issue.

Re: uBitx V6 20M band problem #ubitxv6 #antennas

Are you amplifying the mic at all?  Do you have another receiver that can be used to verify the output of the ubitx?

The only way to be sure is to measure the output.  What I have done is build a -50 db tap (My measurements were -45 db actual) to sample the output of the ubitx with an SDR (RSP1A) based spectrum analyzer.  If you have an SDR dongle of some sort, there are free SA software packages for them.  Here is the -50DB tap that I copied:
http://www.ad5x.com/images/Articles/Tap50dbRevA.pdf
I used a two-tone generator built from a kit to drive a BlueTooth speaker with the volume at about what I expected a person speaking to be, and then held the mic at about the expected distance from the speaker.  You may also need a step attenuator depending on the power of the amp.

Others have used another receiver with the ubitx connected to a dummy load and the receiver with little or no antenna to lower the input signal.  This works best if you have a waterfall display on the receiver.  Again, an inexpensive SDR dongle like an RTL-SDR can work.

I would first verify that you do not have any issues with the barefoot ubitx, then go on to the output of the amp.  When I did similar measurements for my rigs, I found that it was easy to overdrive both the audio and then the input to the amp.  I am currently waiting on a 7 element low pass filter for the amp, as the harmonic output was not within FCC requirements with an eBay 100watt LPF kit that was based on 5 element filters.  I also have a -6dp pad in the works to drop the output of the ubitx to below 5 watts.

FWIW

Checked. CW is just fine. How do I avoid audio overdrive?
