Re: Couple of questions for the gang

Yes, the wiper is still hot. I'm considering something similar. Since you're not going to be using the onboard audio, you may want to desolder or clip the power lead on the 2822 (pin 2). That way it won't be getting any power to go up in smoke.

Hey guys,

Talk about frustrating. My uBitx arrived today and I leave for 6 days
tomorrow. Uggg. Have to wait until I get back.



But I do have a couple of questions. I opened the box and saw that I
have the WX version of the TDA 2822. I am planning on picking off the
wiper of the audio pot and ground to feed a line input mixer I use in
the shack that feeds amplified speakers. But, as I understand it, if
the WX TDA 2822 does go up in smoke, the wafer leg of the audio pot will
still be hot for my line level audio feed right??

Also, I have a couple of 8-ohm 5-watt resistors. Should I run one of
those where the speaker should go and even run an additional 8-ohm
resistor in series to get the load at 16 ohms? That will help the TDA
2822 keep from smoking itself right?



Thanks.. waiting to dive into this thing really stinks..

73-Gary

When the box arrives, most new owners will find their way to 
     http://www.hfsignals.com/index.php/ubitx-wire-up/
and string it up.  Then put on their safety goggles and power it on. 
Hard to imagine 4000 new owners all digging around in the wiki for wire-up errata.

A pointer at the top of the wire-up on hfsignals to a curated errata/addendum webpage 
would allow Farhan to move on to other projects and ignore necessary edits.  
A good example of where this was needed would be the TDA2822 WX blowup,
the latest news was changing daily.

Sure there is. Move it to a forum. I like forums but I'm not convinced this group is broken. 99% of the posts are easy to tell what they're about (B20, B40, uB, BS, ...). If you're having a problem discerning that, it probably means you're not used to the other products. Perhaps the web interface and the provided search facilities would help you.

Good subject lines are important.
For example, "Hey, I've got a question"  is not a good choice.
Nor is "Complaint Department".

The uBitx is a hot new product, 4000 shipped and still a big backlog.
Lots of development going on, and lots of people trying to figure out what it is.
Group activity is at a peak, will fall off considerably in a few months. 

Mike's curated ubitx.net website will have much of the stuff from the forum nicely organized.
The wiki, being a free-for-all like the forum, likely won't be so organized and up to date
as well the curated ubitx.net.   But if you see a pet subject being ignored, perhaps create
a rough wiki page and point it out to Mike.

Re: uBITX Firmware CEC Version Added WSPR function, I am looking for a beta tester. #ubitx

Excellent, Congratulations sent wspr, also Thanks for finding the bug.
I confirmed your callsign at wsprnet.org. The 10 watt output is awesome.
In the next release I'll fix the bug you found and upload it.

Hello Ian,
BPF are working ok now! As you can check IK2YRA on wsprnet.

 It takes me a while to found a delta between Master calibration (175000)and WSPR calibration (149000) i write it to the ubitx and  everything was perfect, so i saved the config as a file .btx to back up. 
But it was impossible to have the wspr cal parameter back on his bitx's Manager field reading from ubtx. 
I try to read it even loading my file .btx, but no way.  The field turns to have the Master Cal value (175000).
It seem to "stay alive" on ubitx's memory but if read it from ubitx and then write it back... you loose the wspr cal value.
Hope i been understandable. 
This is the only bug that I found. 
Thanks for your great JOB!

2018-03-13 2:16 GMT+01:00 Ian Lee <kd8cec@...>:
Philip, Carlos and all

For the WSPR Beta version. Since the HEX file and the uBITX Manager link are in the thread, I send mail from here.
I posted uBITX Firmware (KD8CEC Version) which can beta test WSPR function.
(Version : 1.51W)

It does not use any device to send WSPR the such as the previous version. Only one uBITX board is required.
(A wristwatch within 5 seconds of the error range is also required.)

The problem with previous versions was that the Band Pass filter was not applied properly and the frequency was transmitted outside the WSPR band.
But Philip did the testing in ways I never thought. It is calculated by wrong frequency and entered directly.
The people who saw it in the BITX group succeeded in sending the WSPR according to Philip's method.

It looks like the problem has now been resolved.
The BPF problem was my mistake, and the frequency problem was the calibration problem.

As a result of applying Master Calibration already set in uBITX to new logic, we confirmed that WSPR is transmitted at the correct frequency.

The picture below shows the test pictures at 630M (474,200hz) and 10M (28,124,600Hz).






Before writing this article, Gerald saw the article I edited on my blog and made the test and it succeeded.

I think the WSPR implementation is not so difficult because there are already a lot of open source. I just apply the source code.
Rather, I think the test is more difficult. That's why I am so grateful to those who test me.

Please let me know your test result and I will check it on wsprnet.org and capture it.




Ian KD8CEC

2018-03-11 20:45 GMT+09:00 Philip <philip.g7jur@...>:
Hello Ian.

Is the WSPR frequency calculator in uBITX manager working correctly. Or is the uBITX transmitting on the wrong side band ?.
I would like test the update when you have done it.

Re: F R A G M E N T A T I O N !

Terry Morris
 

This group BitX20 became discombobulated prior to my joining. Upon joining its become difficult and at times frustrating trying to following the different platforms now addressed in this group. I feel each platform should have its own group, e.g. BitX20, BitX40, and uBitX. I have had no problems with my BitX40. Learning about the uBitX problem with toroids which affected delivery time was disheartening but my kit finally arrived after 2 months. Now, I am not concerned with shipping, rather issues concerning functionality of the uBitX before I begin construction and what hardware I need to replace and what software upgrades I need or will enhance my operation of my transceiver. There are no threads, therefore I have to look at every message which is a time waster. I am concerned about the uBitX only at this stage so if these messages, comments, etc. were more compartmentalized I could breeze past those that I need not read. So in general I agree with those that have commented in this thread, that is until the thread is broken.

The solution on groups.io is subgroups. However, that also requires a dedicated/active moderation staff to keep things on track.

Heck, even if we just could get the "when will my bitx arrive", "I got my ship date", "I got my bitx" somewhere else the volume would go down.

Of course, using a menu entry for switching to CW mode does not rule out
including an iambic  keyer.  That's up to whoever writes the code.

The freed up analog pin would be quite useful, I'm thinking SWR/PWR.
I'd guess most uBitx users don't use the internal iambic keyer, will be several sources of
firmware if they want it, perhaps using digital pins freed up by moving to an i2c display.
Or could use a cheap PIC uC iambic keyer to drive the ptt line.
For a basic SSB rig, straight key on ptt is plenty, ideally at the tip of the mike jack. 
This is coming from a guy who has spent much of his on-air time using CW.

Dennis:

I think you've done a good job of categorizing the fragmentation all of us have probably have noticed. I belong to a number of Forums and it's not unusual for me to have over 80 posts in the morning. I want to read them all, but it's getting pretty hard to justify the time. It would really help me, and likely others, if posters would prefix their issue with the general class of the problem, followed by its specifics. For example:

    IDE-Programming: Multiple compile error messages

for a post where someone is having trouble compiling code in the Arduino IDE. I would read this as I stand a chance of helping. Another:

    Complex: A four transistor solution to PTT Thump

I would also read this as it's a problem for everyone. If it's simple instructions, I can follow along. Another:

    µBITX Design: Class E design for new PA

While I would be interested in this, I'm not an EE, so I would likely not read it, plus I enjoy QRP and PA's hold less interest for me. I would also add a category: Shipping Info, as a lot of posts are about when they bought the rig and when it arrived.
I realize getting thousands of people to follow a convention for posting would be difficult. However, I think it would be a HUGE benefit to everyone. Perhaps Arv has some thoughts on this.
