Re: The sBitx Release on www.vu2ese.com
Hah! I tried that last week Don and it didn't work, I see it coming up now though, unfortunately the "Add to Cart" is failing for the board set. I have had a Pi4 and displayed stashed this long time for this project. On Tue, 26 Jul 2022 at 14:50, Don--AE4DW <AE4DW.Don@...> wrote:

Aaron: That is absolutely a terrific story! We need to encourage our young people to investigate our hobby and it can be tough sledding at times. I've told the story before, but at my club's GOTA station during (2015) Field Day, we had a young boy get on the rig. No mic-fright at all and he spent almost an hour talking to people all over the US and Canada. Later, his Mom came to pick him up, and his eyes were the size of hubcaps as he told her about his experience on the radio. Her response: "I'm sure it's a wonderful hobby, but where are you going to get the thousands of dollars it takes to buy the radio?" He looked like he had been shot. We need to do a better job of informing the public that a viable home station can be put together on a lawn-mowing budget. The entire driving force behind the T41 project was to have a 5-band HF SDR rig with enough power (e.g., 20W) to serve as a base station, but do it at a reasonable price. I know that Hans and Farhan share that same goal in their work to bring excellent radios to market at affordable prices. Anyway, your taking time to make those contacts is a perfect example of what can be done with a little time investment and I hope more of us can trace your footsteps. Jack, W8TEE

Re: New ubitx v6 no tx
Cameron,
If installed correctly, the BCI filter would not affect the transmitter.? If the receiver stopped working when you removed the BCI filter, then there is still an issue with the modifications made to install the filter. Can you post a picture of the board where you made the modifications? I do not think it would be a good idea to try calibrating now. The installation and removal of the BCIfilter should not have affected any of the radio parts that would cause a need to recalibrate.? This is assuming it was installed in the correct location. 73 Evan AC9TU |
Re: The sBitx Release on www.vu2ese.com
Hoping I'm not overstepping here, but in case Ashhar forgot to put a link on the main page, I'll mention this. I couldn't justify the fully assembled kit (but so tempting) but took the plunge for the board set. Now to source a case, display, etc. ? ? |
Re: New ubitx v6 no tx
Cameron Jaques
I removed the filter, soldered the trace back,( should be back to factory now) did the cw transmit test and am now getting about 10 watts on 20 meters, about 6 to 7 on voice. So it is now transmitting, but has stopped receiving, all I hear now sounds like digital, no voice heard, it was receiving perfectly Any ideas, re calibration maybe?

Re: uBITX v6 upgrades

I appreciate the help from someone but I think that I resolved my problem with the case with David's suggestion. It dawned on me at 3:00 this morning. I like to make scrollsaw plaques and sell them for radio and astronomy stuff. I'm nowhere what someone would consider an expert. I think of myself as being ok. Anyway not everyone understands so here are my last two projects.
I was in my shop working on another project. Because of the nonstop triple-digit heat, I work in the middle of the night when it cools down some. Since I have the tools and experience with working with wood, why don't I just make the case out of wood and line it with flashing? The flashing doesn't have to be perfect since it would be hidden by the wood.? It would be much easier for me to get a custom size or shape if needed. It could make my uBITX have a one-of-a-kind look. This should be able to work, shouldn't it? -- '72 Aaron K5ATG |
Re: The sBitx Release on www.vu2ese.com
Peter, Frankly, I am nervous. Our goal was to build a high power SDR that will sell for 300 USD. This has escalated to almost 500 USD now. This better live up to its expectations! - f On Tue, Jul 26, 2022, 5:13 PM Peter McCracken <peter.mccracken@...> wrote:

Hi Ashhar, It would be really great to get an updated date for the release on hfsignals, everyone is sort of scratching their heads at present as there have been a few false starts. P. On Mon, 25 Jul 2022 at 10:14, Peter McCracken via <peter.mccracken=[email protected]> wrote:

Re: uBITX v6 upgrades

Aaron, you could always buy a plastic case and install copper circuit board or maybe some aluminum flashing glued all around to give shielding. Plastic is easier to drill and cut and the copper sheeting or aluminum flashing can be glued to the surface before installing the guts to your system.Others might have constructed something similar in the group. 73 David ac9xh

Re: sBITX and Ham Bands
You will have to do that each time you boot up if done via commands I plan to add a telnet facility to allow a remote program to send these commands to the radio. One could operate the radio remotely with just a telnet application, at least for digital modes like the ft8. This could also be used for scripting it. - f On Tue, Jul 26, 2022, 5:27 AM Pierre FK8IH <jb.gallauziaux@...> wrote: Coming back for one more question : |

Re: sBITX and Ham Bands
Pierre FK8IH
Coming back for one more question :
I read in your "sbitx/how_gui_is_organized.txt" file? : "Finally, the cmd field is an interesting field and it goes more than what meets the eye. Lets imagine that the cmd is set to "freq" and the field type?
is NUMBER, set to max of 7300,000 and min of 7000,000 with a step of 10. Now,
this field can be used to tune the radio up and down the 40 meter band in?
steps of 10 Hz. Each time the value is changed, the function do_cmd() is called
with both the field name and the value in the same string, separated?
by an equal ('=') sign. Like do_cmd("freq=7000000"). "
and in the last manual : "\freq xxxx Sets the frequency. You can specify the frequency in KHz or Hz. So,
\freq 7050
is same as
\freq 7050000
You can also use a short-cut and use \f instead of \freq, like
\f 7050" Does this mean that we can set min and max frequencies of a band as well as the step by typing commands with the gui? That we do not have to modify the sbitx_gtk.c file and recompile a firmware? 73 - Pierre - FK8IH |
