Catching Up #firmware

 

I had to set aside my uBitx project since last Summer. Picking it up again, I want to add the SWR sensor to my 4.3 Nextion Display. I am currently running firmware version 1.095. Do I understand correctly that I need to upgrade to at least 1.097 to get the I2C Type Stand Alone Signal Analyzer Firmware V0.7+ necessary for the SWR display to work? If so, does 1.097 or newer still support the 4.3 Nextion Display (i.e., Nextion NX4827T043)? I cannot find any documentation regarding this. Thanks for any help the group may offer.

If you are in or near the US, try tuning in WWV on any of it’s frequencies.

VNC and port forwarding will do what you want.

Re: Britx 40 assembly files?

I found it easier to follow a YouTube vid. It was ~12 minutes long and just showed each component wired up. I don't even know if the vid had sound, I just skipped ahead to each component to see what color wire went where.

Do you mean BITX40? Instructions are right on the page you bought it from.

Britx 40 assembly files?

mtngentleman@...
 

The Britx 40 Kit states that kit assembly files and other documentations from " http://k1el.tripod.com/WKUSBX.html  

This is an invalid URL. Does anyone know the correct one?

Just for testing if you plug in a piece of wire, the longer the better, to the antenna scket you should hear some signals on one frequency or another.
Try different bands and see if you can receive anything.
The lower frequency bands are better at night.

Mark -- I have about the same setup running wspr 24/7 when I'm not otherwise using the rig.  It would be cool to be able to remote into Ubuntu (my Linux flavor on an atomicPi) with some sort of Remote Desktop utility, and control WSJTX or even fldigi and use the rig remotely, but I haven't figured that out.

Re: Antuino 2.0

Rob Bleumer
 

HI all,
I had the experience that the AD8307 is verry sensitive to HF signals. For my sweeperino I had to protect it by puting it in a shielded box. Even my WSPR transmitters 0.2W were disturbing the messurements in my shack with mij Sweeperino build with RAZZIES solution of dragons . Here I see no protection at all and many HF signals coming from SI5351.
I propose puting it in a seperate shielded compartment even so the 25Mhz filters to avoid problems.

I have experienced the same thing and at times thr SWR just jumps all over. I keep resetting it and calibrating it and when it does settle down it is solid and gives the same results as my other meter (YouKits FG-01). Am waiting for more info on how to deal with this issue. It also happens with a good MFJ 30 watt dummy load.

At 50 Ohms with a dummy I get 1:1 sometimes 1:1.1 right across the spectrum.
Tried 30Mhz +- 25 then 50 and also 100 mHz.

at 75 = 2.3
at (50 || 50) 25 = 3.5 << should be same for 100 ohms

Sometimes the values are erratic.

Recalibrated both. Little difference. Occasionally reads 2.3:1 then goes back to 3.5 (wth 100 ohm non inductive load.) Pretty much the same from 8-30 MHz. 200ohm load shows 8.7:1 SWR. Same loads on VK5JST analyzer shows 2:1 and 4:1 (+/- 2% and pure resistive) over same frequency range.

Wear a mask with good ventilation.  Neither the dust from grinding off the paint or the fumes from the paint remover are life extending.

 Hi Jerry,

   Aren't Sunil's cases awesome??! My slacker's solution to the chassis grounding issue was to apply a little methylene chloride based paint remover to the
interior side of the mounting holes with a cotton swab, give it a couple of minutes to work, clean it off with a wet cloth, and give the bare metal a touch of emery cloth.
  Worked like a charm.

Hi,

I would like to set up a permanent QTH and probably just work 30m for QRSS and WSPR

Has anyone created a setup like this where I can remotely control my setup over the internet?

Re: Grounding

KD2QMZ
 

To get a good ground on the case, make sure that from the power negative wire to the neg of the antenna connector, there is a wire with the right gauge. Also, I prepared a wire with terminals, so I can screw those in very tight to the antenna connector, which also brings ground to were the antenna wire from PCB starts at.

If you notice, the wholes for the screws on the board, also connect to ground, so again a wire with terminals from any of those after checking it is connected to ground, then to the antenna connector will do.

If it is a metal case, yes scrape the paint off where you want earth connections. If it is a sinthetic case like plastic, nylon ect. Then is will serve no purpose. Then you have to construct a metal post an connect the post to the negative connection of the connector of the 12V supply.
