Re: New ham, Ubitx issues #ubitx

Dear Jerry, KE7ER
You are exactly the kind of person I hoped to encounter in Ham radio. I love DIY, and I love the sharing of knowledge. This is was brought me to the uBitx. Also, your post was the PERFECT step by step guide to finding my problem, and solution!

So, I don't know if anyone has noticed on the V4 boards, but RV3 is crooked from the factory to clear the heatsink. Well, somehow, over time, one of the legs on that trimmer broke so it was now feeding Q94 with around 5v! no bias adjustment possible! All I had to do was swap it out for another one and we are back in business! set the finals to 100mA each and all seems good! Thanks again from everyone who chimed in. I have asked the Ham that did my exam and he said, as far as he reads it, the ubitx falls under "assembly of commercially available transmitter kits of professional design". I will get him to check it over anyway, but I'm not about to stay in bed afraid of the world. I will also be studying towards my advanced, as homebrew QRP is what I am most interested in.

Thanks again,
Dayne, VE7DNT

Re: Question about power output #v5 #ubitx

Ted
 


Bonjour,

The proper setting of the BFO is very important for output power as well as for receiving, it seems.

I would suggest setting this to 11,056400 and see how the output power is on the bands.  I have one V5 set for 11,056560 and another V5 set for 11,056210, so my suggestion here is about the middle of those.

After this, if the output has improved, one might find an audio spectrum graph application (or the HF Signals web page tool for the purpose) and find your specific BFO value that performs the very best on TX and RX alike.  



Bon chance,

It’s not an idiots guide, it’s a learning process. We’re all going through it, some have just started earlier. I went through this exact issue about a month ago. 


Best of luck. Enjoy!

I hope we get to talk on the air.

Bill,

Thank-you again.  i see that it is a "basic" 2.8" unit.  I know where to get the KD8CEC firmware for the Nano, are you saying that the source on Git hub had the tft file for the Nextion as well?  When I downloaded what was there I could not get it to work with my 2.8" Enhanced display.  I also could not get the source to compile, as it said that there was not enough memory.

I am new to the Nextion editor, so it may be something simple on the settings that I do not know about.  I have built 3 units, a 2.4", 3.2" and now a 3.5", however all have been from tft files.  I did not have the issues that are happening for me now.

Question about power output #v5 #ubitx

Anthony F4HUY
 

Hello,
got my ubitx v5 one month ago, almost finished ...

it's sell with "More than 10 watts up to 10 MHz, 7 watts up to 21 MHz, 2 watts on 28 MHz" ,
i get 2w between 21 an 30Mhz, then the power drastically decrease under 2w under 21mhz, around 800mw at 7.1mhz, and close to zero on 3.5mhz

what's happen ? it's should be the opposite.

i have already checked and re*tuned rv2/rv3, my microphone is a baofeng, test with cw give same result

i want to operate mainly on 20meters, hope 5watts, should be nice.

any idea ???

Re: KD8CEC ‘s SWR senser

Vic WA4THR
 

Whoops! My error, now discovered. Nothing like making a post for help to dicover the problem on you own!

I assumed I had the latest DSPMeter sketch (v1) but it appears by looking at the upload dates that (v0.8) is a later version by about 11 days. I guess I didn’t understand the naming convention. I have now installed v.08 and I am getting good SWR indication.

Re: uBitX on CW #v6

Jim
 

Would the (now discontinued) CW Conditioning Board (here) help fix this?  Seems easy enough to home brew this circuit.  Still waiting on my V6 to arrive, but I'm a CW-only kind of op and keenly interested in this.

Re: KD8CEC ‘s SWR senser

Vic WA4THR
 

I read your post that you have the SWR function working on your uBitX. I have a V4 that I built a year ago and added the Nextion display, then added the second I2C Arduino and I am able to do all functions with that including CW decoding, audio spectrum, S-meter and so forth. All has worked well for many months. In order to eliminate taking a separate SWR bridge for use with my loop antenna when going portable, I decided to add the SWR bridge in KD8CEC’s website. I built up a Stockton bridge and I am measuring good results with itI, with FWD power in the 1.7v range and maybe around 0.5v in the REV pad in a typical check. SWR caculations by hand match actual SWR pretty well. I wired the FWD and REV pads  to pins A2 and A3 on the second, I2C Arduino and on transmit I see nothing…no deflection of the S-meter graph at all.

Did you have to do something different that just connecting the 2 wires? I didn’t run a ground wire as the SWR bridge is already connected to ground through the antenna connector, and the second Arduino is connected to its own ground as well. Is there a switch in software?  I am using version "UBITX_CEC_V1.100_NX_S" of the KD8CEC sketch and “dspmeterv1” dated 4/1/2019 on the second Arduino. Thanks for your help.

Legal risks are not something I would worry about, especially at QRP power levels.
Cease operating if you get a complaint, verify your equipment is not at fault before resuming.
If that's too much risk, you'd best stay in bed.

Most of us take far more risk everyday when we get behind the wheel.
Or make our way on foot using a crosswalk.
