Re: #sbitx sn 0071 is alive!
#sBitx
Farhan - Yes, I do see the console activity on port 7000 - yet another cool thing that this amazing radio does. The text interface capability would make possible remote digital modes QSOs and control through simple devices - maybe an ESP32 based handheld device or a simple smartphone app. So many possibilities for experimentation and hacking have been made possible with the sBitx. I'm doing something right now that I would have never thought possible with a ham radio - I'm responding to your email using a browser running on my sBitx! 73; Steve, N3SB On Tue, Aug 16, 2022 at 7:50 PM Ashhar Farhan <farhanbox@...> wrote:

Re: apt update/upgrade
#sBitx
Mark, Go ahead and do it. You have two safety nets. First, the original sd cd image is on the gdrive link on (it is too large to be on github. Second, you can make an SD card backup from the menu (I dont remember where exactly it is). Or you can use the venerable dd command (look up the usage on rpi forums). Except for the config.txt, I don't see why apt update should change anything. Try both. On Wed, Aug 17, 2022, 7:05 AM Mark Earnest via <mark=[email protected]> wrote:

apt update/upgrade
#sBitx
Mark Earnest
My sbitx basic kit arrived today and works perfectly (sbitx #77 is on the air as I type). I'm keeping it under 10w for now until I replace the voltage regulator, but so far so good.? The linux admin in me wants very desperately to run an apt update/upgrade on this, but I wanted to make sure first that the currently sbitx software isn't relying on the specific versions of anything that were pre-installed on the sdcard that was shipped with it. Is it expected that we would maintain these as any other raspberry pi and perform that update? My intention is to have this connected to the internet and remotely accessible so I would want to apply security/bug patches from the apt repositories regularly.? |

I believe it was an ARRL award, but it was long enough ago that it was probably one of the first FT8 WAS awards. Did the rules change? (I don't follow those things.) Jack, W8TEE

Any suggestion of a link where to buy it? Where is it located in the main sbitx board? Btw, this radio is a dream! I really like the way you used the 2 LR channels of the audio codec! Rafael On 8/17/22 03:15, Ashhar Farhan wrote:

Re: 66W on sBitx
I'd be more concerned than impressed - that seems way too high, given the components used.

Re: 66W on sBitx
Rafael, I would suggest installing a switching regulator before you pump up to such high levels. The transistors need to run cool. On Wed, Aug 17, 2022, 5:27 AM Rafael Diniz <rafael@...> wrote: Hi everybody, |

Max, Keven Loughin, KB9RLW, did a Youtube video, "Ham Radio - The doublet vs EFHW noise rejection cmparison."? where he shows the effects his and his neighbors inverters have on reception. He lives in a RV and has converted just about everything in his RV to run off 12V and seldom runs his inverter. -- Jerry, AC9NM 手中的鸟在灌木丛中值两个 |

Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
I do not see a problem. As long as we are gentle when winding the coils and add shielding per Ashhar’s instructions for the filters, we can just use minimal ‘fill’ for a nearly hollow PLA toroid form, right? Or maybe I missed something (it would not be the first time)?

Steve, You might want to telnet to port 7000 of the rpi while sbitx is running. This an easter egg yet, I am not sure if I should produce a telnet remote or a web/http based remote facility.? It only shows the console output yet. The source code is at? On Wed, Aug 17, 2022, 5:03 AM Ashhar Farhan via <farhanbox=[email protected]> wrote:

Re: #sbitx mod
#sBitx
To track down the hum and spurs, I had a trick. I use a spectrum analyzer with its input connected to the DC power line through a 0.1uf capacitor. The important thing is that the RF cable between the Specan and the radio should be connected grounded properly at the radio end with a BNC connector, its ground tab directly soldered to the ground plane. This is an important detail. - f On Wed, Aug 17, 2022, 5:11 AM JerryP <jponko@...> wrote:

Re: #sbitx mod
#sBitx
Scott, I think you're probably good to go at this point. Extra bypass filtering on the output never hurts. In the olden days of HAM radio, 60/50Hz hum was the big problem with power HV power supplies. If your scope has Math functions you could use the FFT math function to look at the 200kHz signal and its harmonics. Otherwise, an AM radio would work to see if there are harmonics being generated around 600kHz- 700kHz and 1000kHz-1750kHz. Just tune across the AM band and see if you pick up something then turn the buck converter off to see if it's the source.

Re: DAYLIGHT RADIO - PLASTIC TOROID MASTER
David, I did a bit of experimental work on this. The toroids need more than 15 turns or so for the self-shielding to work well. At fewer turns, the shielding though better than that of a conventional inductor, wasn't good enough to be used in a bandpass filter. In the Daylight radio, I had to add shielding between the three sections. - f On Tue, Aug 16, 2022, 11:48 PM David McGaw <david.g.mcgaw@...> wrote:
