You might want to try one of these C5000 it likely will be 1/2 & 1/2 learning and prebuilt. Just have to google search correct two pins to cross connect in order to power the card from the USB port 5 VDC supply when in use.  see att.  I believe it may be avlbl at digi key for about $10-$15

I need to buy a cable to bring the usb out so I can plug my pc in. I know things have changed sine I used packet radio so woot! As soon as I get the guts to open the case.

how to access plot screen data from Antuino?

Stephen Dubin <dubinse@...>
 

Is there a way, preferably without recoding,  to acquire the data from the plot screen of Antuino? For example, can it be downloaded through the USB port as a text file?

If you learn how to use some low signal digital modes, such as FT8,JS8 and even narrow ARDOP WINMOR.... You are likely to have a lot of fun

To pay it back, study, learn all you can, rub shoulders with other Elmers, and don’t be afraid to tell about your mistakes.  Then when you find other like minded new hams introduce yourself and make yourself available.  A lot of the hams I have met were shy and not outgoing, but once someone showed them a little attention they blossomed, and some of them passed me in knowledge and learning and went on to Elmer others.

Isn’t this fun?

I hope this works, this is my first attempt to post. I received my bitx v3 yesterday and took a long time before connecting it to power because I didn’t want to smoke anything. With help from the original Elmer whom can be identified if they wish, and another ham cheering me on I had the guts to power on my first uBITx v3. I have tuned to wwv and with my dipole a mess across the floor I can clearly hear it at 10.000 with a half wave 20 meter dipole.

I am over the moon, the case is even the color of the tempo one my dad purchased for my twin and I as kids. I want to thank the community at large and the ham that sent me a rig. I have to find out how to pay it back now.

Hams are the best.

Great news. Now educate them both to the advantage of your now being a communications node when other means fail.

That is a good idea, but again I can’t change my environment. I didn’t hear a lot of noise today but it’s a little late to try now. 

I am going to hang my dipole and get a pass through opened tomorrow. 

I’ll start working on noise issues as soon as I have the rig set up at least on 20.

Re: Antenna Question #antennas #v3

Hello

I’m aware of the possible issue. I thought the same, however the equipment and batteries are all 3 floors down and on the back of my building. I tested my bitx today and while there was a lot of noise I could easily pick out wwv at 10 MHz. I’m obviously not going to be a prize winning station. However considering the fact that I live in a slum and my landlord is allowing me to hang an antenna on my apartment building at around 40 feet is progress.

Now to laminate signs with the rf symbol on them.

I have placed an o ring under every socket for the motherboard, aprox .7mm thick. More is a problem couse of the holes for the mok,phones and  volume. And yes this is bad cause of bad measering or bad screen production, i have this problem now.
So i put the radio together problems are not soleved. Other thinking, maybe place an nextion screen with the other software? But again, when this is not realy the problem, i spend again money for nothing😣😣. Next weekend i have some off days and i go try again. Thx for helping you all.

Measure the noise during the day and during the night and if it is vastly different that will let you know that you’re picking up noise from the inverters. 

You can measure the audio output AC voltage with the volume control in the same position each time, at empty places in the band.

there is a bit of 'science' to feeding an effective antenna, particularly if coax is involved.  as well as Gordon's query regarding metal on the roof (but if there is maybe you can be much more than about 5 feet away).

do network with the gang to implement an effective antenna.  glad your new friends are using your fun for a break in the monotony.  keep everyone safe.

The roof is covered in solar panels. The plan as it stands is to run the dipole along the edge of the roof. This is not ideal but works. The main drive is to keep idiots from getting ref burns.

This seems like my best option.

Re: uBitx v6 Microphone #v6

 

Ugh!

That would mess things up :-(

Good luck getting it all straight.  The main thing is to keep the connections well plugged in, and to make sure you get a good ground connection at each screw or stand-off.

That mis-alignment is pretty bad though.  Are there different size stand-offs in the kit?  Maybe different ones on the main board would raise it enough so the front will line up?

Re: CW Filter

Hi Reg,

tnx for your reply; I saw this LED AGC, running at audio stage, before choosing this one, running at RF stage:
https://shop.kit-projects.com/index.php?route=product/product&product_id=101

I'm quite confused as this last AGC has a wire connected to the yellow wire of the volume pot:
I'm not sure I can insert the Sotabeams filter in line between the tip of the pot and the wire coming from the AGC PCB ?

Did you insert yours this way ?

Be mindful of a lot of metal on the roof. We have installed antennas on the top of two professional buildings, that both had extensive metal flashing and extensive  lightning arresting systems.  

These appear to create RF coupling to the antenna that we placed, and we had to move the antenna as far away from them as possible to get in and impedances to look anything like what we are used to.   When the antenna was 5-8 feet or so above all of this metal, impedances in the five ohm range were measured which should have been 50 to 75     We were forced to move antennas way off the roof to the side or above to get manageable impedances.

This is true, the maintenance manager is in fact a cber. I am still thrilled at the prospect at having a dipole at 40 feet. And my landlord wants it.
