Re: Anyone with a good working configuration for CW with the KD8CEC software

 

David

1. If the reception frequency of CW is different from the transmission frequency, it can be easily solved by uBITX Manager.
In uBITX Manager, if 'Shift Display Frequenc on CWL and CWU Mode' is checked, uncheck it.
I had this option so nice that it was used automatically.?

2.uBITX_Manger Backup file contains Calibration values,?
Please make your own uBITX configuration information as a backup file first. and upload another user backup file to your uBITX after modifying Calibration and BFO.

I have uBITX configuration backup files for several users. If you want, I will send my configuration file to your personal e-mail.

3.A new version of KD8CEC with WSPR functionality will be released in a day or two. Several bugs have been fixed and some improvements have been made.
?In the new? version, I are considering not to use avove #1 Option ( ?'Shift Display Frequenc on CWL and CWU Mode'??) automatically.
?I will listen to users' opinions and make a decision.

I'm having trouble getting the TX and RX frequencies to match on CW.? If anyone has a good configuration for this, would you please post or send me the uBITX_Mgr .btx file.
Many thanks,

Sorry you got an Internal Server Error.? These occur periodically when the server runs out of memory (i.e. whe 6000 BITX20 list members go to the website all at the same time!).? They clear within a few seconds to around a minute, and only occur every couple of days.? Sometimes they are the result of Denial of Service attempts.?

Some things to check:

1) Have you checked that you are connecting to your uBITx (e.g. in the Arduino IDE)?
2) Have you selected the Hamlib FT817 as the rig and the correct port?
3) Have you the correct baud rate setting and stop bit?

??? 38400 baud 1 stop bit.

I don't have HRD so can't really comment on "how" you do this! may be helpful

Re: Modifying Bitx40 BPF band pass filter

 

Final update: I restored the resistor values to their original sate and instead added an amp stage (half of Bitx bidirectional amp) and that gave me a much stronger (+15 dB) and more stable DDS/VFO signal. Instead of adding windings to the toroids in the BPF I increased the the capacitance of the 3 tuned circuits in the BPF to 125 pF (instead of the 100 pF in the original design) and that placed the 7.000 to 7.200 exactly in the peak of the filter. It was a matter of trial and error but got it working.

BPF is perfect now. Thanks all!

Re: a Little Gun Shy #ubitx-help #ubitx

 

Ok.
I've checked out your site before...
Just was gun shy to ensure i had the farhan load..
So your steps are fine ..
reloaded Farhan no problem. all good
then did IanLee's version...uploaded fine now to review his site for the menu settings.
Still No CAT control with HRD..;=((

Mike,

Getting this on your link.

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@... and inform them of the time the error occurred, and anything you might have done that may have caused the error.

The KD8CEC Memory Manager requires mods to the stock firmware or installation of Ian's firmware to work.

Check out the guide at:? ? and feed back with any issues, as I want to get this right!

a Little Gun Shy #ubitx-help #ubitx

 

So,
My uBITX is working fine, so I should just leave it alone...Of Course not..
1.? Before I start mucking with the sketch, I want to be able to get it back to what came with the rig.
so went to?
downloaded the zip as usual.?
Inside there is the ubitx_20 folder the .ino with the ubitx_20, is, I assume that is what should be uploaded to the nano?
Is the CAT function an original part of the sketch that will get loaded with the ubitx_20..that i haven't tried to use? as I would like to have HRD control of the uBITX..
ugg..
?
Must not be thinking this through, Allard's changes on my 40 seemed to be easy enough.
quick answer would be appreciated.

Re: Dirt cheap uBitx case #ubitx

 

Thanks!? Ouch, always when you think you're getting close to done...?

I've added the rj45 jack for my spare handheld mic along with a mini usb port on the back. I still need to wire up the up/down buttons off the jack.


I left the front plate with the original jacks in case I want to ever use them again.? If I don't I'll end up creating a new faceplate and have the rj45 jack directly on the front.

There is now a 1" fan in the top along with a 2" speaker.? I ended up replacing the green screen with the blue and it's quite a bit easier on the eyes.? The case was painted hammered black on the top and bottom pieces. The front and back plates got coated in hammered silver.? I wanted a bit of an old-school vibe with the hammered paint.??



I realized I never gave the case dimensions - it's 7"wide x 6.5" long and 3" tall ( ~17.5 cm x 16 cm x 7 cm)
When I make it back to the office I'll be printing up laser water slide decals for some last minute embellishments and labeling.?
At this point I'm not sure I'd do another scratch built and recycled case due to the effort and extra time.???(lies, all lies)?I definitely spent more time and labor costs building and assembling than I would have if I bought a pre-made case. I've still got some more cable management to do on the inside but had to throw it all together for a quick distraction.??


Re: uBITX Manager

 

Ian,
I am having difficulties trying to get uBITX Mgr v0.2 to read from UBITX.? I've tried the resisitor solution and the capacitor solution with no data showing in Manager.? The display does show db:40000000 and second line the standard LSB and Frequency.
any suggestions (from anyone would be appreciated)

Re: Solving problem with when plugging in a headphone causing a shorted to ground of C77 470uF to ground and may damage U1 TDA2822

Best bet is to plug in mic and headphones & antenna before you turn on power.?

If you don't use a? speaker? with your uBITx and use only a headphone. best idea is to add a 1K resistor to the negative lead of C77 (470uF capacitor) to charge the capacitor slowly when? first power up. Now when you insert the headphone ,any accidental shorting of the sleeve and tip to ground will not create a surge? from the U1 TDA2822 since? c77 is already charged by the 1K resistor. this will prevent a loud pop on your headphone as well as possible damage to the audio amp chip.

Well....... with all said and done..... this is what I finally decided to purchase for my beginning setup:

a simple set up for this beginner...... trying to keep things inexpensive for the time being.

That looks like a great kit for the price. I spent more than that for just
a Weller SP40NK 40W soldering iron (with 3 tips) from the local Home
Depot. Of course, I already had all the other things on-hand, such as
third-hand, brass tip cleaner, Kester 63/37 rosin core solder, desoldering
wick, soldering iron stand, temperature controller, and so forth.

Recently, I got into SMD soldering, so I added a hot-air gun,
a toaster oven (re-purposed as a reflow oven), and a syringe of solder
paste.

If you are new to soldering electronics, be aware that there are practice
kits available for both through-hole and SMD soldering practice. These
kits come with an etched PCB, as well as all the components. Usually,
they will also be a functional circuit of some sort or another, so you can
test to see if you have done a good soldering job, or not.

Good lighting, a clean work area, and a magnifying glass or loupe to
inspect your work as you build your kit are also must-haves.

Good Luck with your new Soldering Station!
