Re: 630M with CEC firmware #v5

Evan Hand
 

The next thing that I would try is to go into the sketch and change the limits in the software.  From a prior post:

I checked the source code on Ian's, KD8CEC, github account and found that there are two different limits for frequency limits:
Lines 112-118

// limits the tuning and working range of the ubitx between 3 MHz and 30 MHz
#define LOWEST_FREQ  (3000000l)
#define HIGHEST_FREQ (30000000l)
 
//When the frequency is moved by the dial, the maximum value by KD8CEC
#define LOWEST_FREQ_DIAL  (3000l)
#define HIGHEST_FREQ_DIAL (60000000l)

Based on the descriptions only (I will need to dig in deeper to see if this is true), I would suggest you go to the 80 meter band and tune down manually from there.

The alternative is to change the #define LOWEST_FREQ  (3000000l) to a value lower than the station you want to receive.  Then recompile and download.

If I set up WSPR Beacon mode to TX on 630M it does put out RF

if your display switches between U and L - we can trust that the rig may be switching also - so this is a horse of a different color. 

if you cannot tune in a SSB signal - I am concluding your BFO calibration is off.

while maybe you have not seen a receiver with a BFO in years - well they have them hidden inside now.  if the last mixer's oscillator is misaligned badly with your IF filter - well you get no signal.  look up instructions for BFO cal for v6.  likely you can do it by ear (as I did) but there are others using a PC tool to adjust it.  be patient with the adjustment and you can get it correct.  if someone can provide a hint on a starting point for v6 BFO that would help here.

Go to HFSigs and click on the uBITX V6 link.  Standard browsers should direct you to
the proper page.  This works for me using Firefox and using Chrome browsers. 

Software for the Raduino is located at https://github.com/afarhan/ubitxv6

Admittedly the above URLs do not include a Heathkit style step-wise instruction set with
check-off boxes for every action and photos or line-drawings to identify each component. 
I think the intent was that hams with some skill at reading schematics and identifying
components would be able to build their uBITX from schematics and pictures.  For
non-hams and very new hams this may not be enough to insure a successful build. 
But there are a number of on-line videos and documents that may help with your project.

https://www.youtube.com/watch?v=JBD6wLeZ1k4 provides a video of the build process.
https://www.youtube.com/watch?v=8urnR299fbI is a video on his working uBITX
https://www.youtube.com/watch?v=Yfhmcili8x0 shows plastic box to finished uBITX activities.
https://www.youtube.com/watch?v=sXJmAhpAjeI video talks about setting the BFO adjustment.
http://www.f6hoy.com/ubitx/ uBITX pictures, cabinet, modifications and build comments.

And so much more info available on-line with just a few Google searches.

Disclaimer...There will always be a few who complain about various issues.  Some of these
complaints are valid and do deserve help.  Others are the result of a bad dinner, lack of
sleep, and so on.  These too deserve at least offers of help with their BITX builds.  We
cannot solve all the world's problems, but we can try to make sense of BITX issues.

630M with CEC firmware #v5

Glenn VE9GJ
 

Hi
I have a v5 ubitx with CEC v1.2 with a Nexiton display. I am doing a bit of experimenting on using the uBitx for 472khz.
Right now I am using a dummy load of course and watching the output with an O'scope. I can CW TX on 160M NP and can TX on 501khz.  Power is produced as seen on the O'scope which also show a LPF is absolutely required below 80M.
If I CW TX at 500khz it will go into TX and produce a sidetone but zero RF out.  I have looked through the CEC source quickly but I can't find where the < 501khz TX restriction is located.  Anyone have any ideas?  BTW I am entering the frequencies direct from the touch screen.
