Dave just sent me instructions so I'm good to go.

Provided switch is a 3-way DPDT on/on/on. My kit arrived today. Anyone got wiring instructions?


Re: Kit projects AGC install - extremely frustrated.

 

Hi,

Three throws means three separate contacts for each pole.  So this would require three contacts for each pole and one contact each for the pole itself.  Thus eight contacts are needed for a DP3T switch.  The on-on-on specification does not change that.

Perhaps the switch is like one of those below?



Cheers,


Mark.

It hides the cw info while on. You can pluck the code off of the hmi's below

The hmi I was working with from CEC didn’t have the spectrum on the main page.  I suppose I can figure out how to get it there. Is there a link to a hmi with it included I can load up. Any size will do. But then it will hide the CW info unless it goes away when in CW mode.

Kevin,

That pic was from the amateurradiokits install picture repo. I'm pretty sure I tested for polarity before soldering and it was correct. I don't remember the physical orientation of the fan.

MRM, I like your approach, which looks pretty foolproof to me.  I used a different approach - SS resettable fuse, PNP FET reverse polarity protection followed by 5V regulator to supply just the nextion.  You have spurred me to re-examine the PNP FET connections.  A job for later on.

Sam, thank you.  I will reverse the wires, add a resistor and a cap.

Hi,

Saw this referenced on ubitx.net. How is the project going? Sounds like a great addon. Be happy to be the test subject on a V4 board. :-)

Hi,

Where are the latest tft? I looked on github and they were dated back in August. Looking for 3.2 enhanced.

Hi Ted. I briefly saw your screen layout and understand Sams questions. Yes your S meter is slightly off. It runs over the white lines that which are part of the image. Also the frequency dot Sam is talking about is a image on the layout of the screen. If one wants to move the frequency around they have to adjust the frequency dot graphically as well. 

This is a screenshot of my 5” layout. I’m working on the other screens but will make this 5” layout available soon.

Hi, Sam.

Please explain what you mean by painted items.... do you mean things like the S-meter path that gets overlaid with the moving meter graphic during operation?  What does controlling a decimal via a button do?   This may sound silly, though it's all to do with me figuring out how the programming works and what can be done with it. 

Retaining CW settings after a reset would be handy, as would a quick and easy RIT to account for the difference  between one's own freq and the other guy's setting (600-800hz) especially when using a narrow RX filter.

Re: Kit projects AGC install - extremely frustrated.

 

Mark, it is a DP3T on/on/on often referred to as a shorting switch.

 Jack, the schem we use is the same as nd6t's with the addition of a 5v reg and not as many decay setting options that's it. Once I get back to my computer I will send it to you. Also will add same as Tim has. Make a new thread or email us don't derail another's thread. may be try to be less insulting or rude.

Hi Ted,

Yes...s-meter, etc. Funny...just did this last night. I wanted the freq display more to the left and down a bit. If the decimal is painted, I have to move the freq controls and then figure out where the painted decimal needs to be and then edit the picture. With a button, I just control the x,y,w,h and I'm off to the races.

Re: ubitx version 2 - substitute darlington for Q70 (MMBT3904) to increase stage gain?

David Feldman
 

Thanks, Tom -- that's what I'm seeing. Through the transverter, with an old HP 8660 synthesizer providing -140 dBm, I am just barely able to hear the synthesizer (so I think noise figure is OK), however, the overall audio level is not very high (just barely adequate.) If I put the output of the ubitx through a PC amplified speaker, it works very well - plenty of audio. The TDA2822 audio output amp is able to provide adequate volume with a higher RF input to the radio, so I figure getting some additional audio gain would suffice, and perhaps be simpler than manipulating the RF line-up. Hope that helps explain my goal!

Thanks again,

Dave
