Re: low output only on 40m

Vic WA4THR
 

I have been following this thread with a little confusion, and I am not sure what the resolution is or if there is one. I have a V4 uBitX and the 40m CW output has always been low. Where I see 3.5w out on 40m CW into a dummy load, I can see 12w when on SSB and "Ahhh"ing into the microphone. I see a similar disparity on 17m. Since the SSB output is reasonable, I haven't worried about it too much and assumed something about the way CW is generated isn't unbalancing the mixer enough or something. Is there a fix?

FWIW, i am using KD8CEC v 1.1 software.

Re: uBITX V6 Sideband Issue

Jim Sheldon
 

I am sorry Farhan, I just downloaded and installed your LATEST from GitHub (V6.1).  The TRANSMITTER is still being offset by the sidetone, NOT the receiver.  You have NOT fixed the CW offset issue and until thatj is corrected, you will still be getting complaints.  

I TESTED this on the air with a local ham and he confirms the fact (he was using a Yaesu FT-5000 commercial transceiver). I had him tuned in on exactly 7025.00 matching the 800 sidetone to the incoming signal, CW and LSB selected.  The V6 uBITX was transmitting on 7024.20 KHz.  That is a TRANSMIT offset, NOT a receive offset.

Sorry, but it ain't fixed yet and has always been like this since way back in Version 3

The Saga continues.... uBITX v5 Firmware update

Daniel Flanagan
 

Hello again,

I now have all the tools I need to update my uBITX V5 firmware to
KD8CEC's V1.2 firmware thanks to the help of this group.

My new problem is my computer(s). I am using Windows 7 Professional
service pack 1.

I want to use XLoader to upload hex files to my uBITX V5, however I
can't get the CH340 driver to install properly. No com ports are
recognized after installation (none show up in device manager). When
I install the CH340 driver it tells me that the driver has been
installed in advance, i.e. pre-installed. When I installed the
Arduino IDE it installed a bunch of drivers. I thought that might be
the problem so I removed it (using Revo Pro which removes everything
associated with the program).

I have also tried doing this on my Windows 7 Home premium computer
with the same result. Can anyone tell me what I am missing?

Thanks,
Dan (W3DF)

You NEVER offset the transmitter by the sidetone value in CW. That makes the dial inaccurate and can cause inadvertent out of band operation very easily.

The way CW works on ALL, repeat ALL properly designed transceivers that include CW as a mode is, when in CW mode, the keyed carrier MUST be on the exact frequency shown on the transceivers dial or whatever frequency indicator is used. The RECEIVER is offset by the sidetone frequency and in the direction from the transmitted carrier to put it in the center of whichever (USB/LSB) sideband is being received at the time. This allows the operator to tune in a CW signal to match his/her sidetone frequency and be basically zero beat to the received signals actual transmitting frequency.

Until the people supplying the software used get this fixed, CW will never work right.

By the way, our TSW group has done it right from the first time we came up with working software for the uBITX and all our software has CW transmitting on the dial frequency with the receiver being properly offset.

I'm working on the CAT interface that Hans added to his QCX. My goal is a CAT interface that doesn't require you to lug a laptop with you into the field for a SOTA activation. So far, it looks like this:

Inline image

and I've been following this thread to see what the consensus is for frequency changes. Like they say about us economists, "If you laid all of the economists end-to-end, they'd never reach a conclusion!" It appears to be the same here. I think my solution will be a NO push button on the front panel that advances the increment value by one digit (e.g., a 10x change) each time you press the button. After a user-defined number of presses, it "wraps" back to the starting position. I would probably start with the 10Hz digit and have 4 presses (e.g., 10KHz) before wrapping back to 10Hz. Since this will also be Open Source, the user can easily change the "press" count factor. My version uses the Teensy 4.0, which has a mega-munch of memory and a 600MHz clock, so adding features isn't an issue on the display side of things. I think this approach for a frequency delta is better than an encoder switch press because my tests suggest it obviates the "rig sliding" problem which forces you to hold the rig with one hand as you press the encoder switch with the other. Given what I've read in this thread, the NO switch seems to be a viable solution.

The T4 is overkill for what it currently does but, because it will be Open Source and in C, you could easily substitute a cheaper chip (STM32??) for the $20 T4. However, I need the resource depth and horsepower for the bottom half of the screen. I still have a lot of work to do, but, man, where can you have this much fun for $50?

Barry,

Did another quick test to see if the Si5351 drive might be the issue (this was one of the theories put forth before).  Measure both signals at TP2 with my scope.  Only real difference was the frequency, though the 3.55MHz signal was closer to a square wave, as would be expected. Values were about 480-490 mVpp.
