KF8CEC¡¯s firmware question
|
Hello everyone!? I¡¯m trying to use uBitx firmware for another rig restoration, and I¡¯m having issues with the CW mode¡ long story short: How can I disable TX line during CW and just get the CWkey pulses? The radio I¡¯m working on requires just one signal instead of Tx+CW keying pulses. |

There appears to be a bug in at least 1.2 that the "STOP function does not prohibit TX. This is true if you use STOP from the Nextion and also if you disable it via the Encoder ("Yellow Window") option that appears after you enable "Setup".. Perhaps not a bug, just never implemented.?
Perhaps some of the OM on this list have some history on that function?? If I get some time in the next couple days I will poke at it and see if I can at least fix this in V2 CEC. 73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040, Teensy 4.0, and Raspberry Pi Pico https://github.com/aj6cu |

Hello Mark, I¡¯ll have the whole Saturday off, maybe we can exchange ideas on how to make this work¡ I¡¯m working on a RFT SEG15D. That radio have it¡¯s own CW switching method, means when you select CW mode and press PTT it start to send code. It was designed for straight keys.? But uBitx needs to be put on TX and use CW key to unbalance the first mixer.? In my board I managed the 2 pulses on the same line with transistors on switching mode¡ so if I use a keyer, I¡¯ll have a continuous pulse (TX) plus a switched pulse (keyer) and the rig will see only a continuous pulse¡ I need to stop the Tx pulse on CW mode in order to use the keyer ( and of course stop shutting down those 2 oscillators that are down for CW originally) That¡¯s basically what I need. This is btw the second rig I modified. The original synthesizer is 50 years old technology and shows a lot of problems, no mention that is huge and allows to work from 1-11.999MHz¡? Thanks for your reply? 73¡¯s de Eduardo/W5EGM On Thu, Jun 8, 2023 at 8:30 AM Mark Hatch <mark2382@...> wrote: There appears to be a bug in at least 1.2 that the "STOP function does not prohibit TX.

Eduardo,
Wow!? That is a different approach!? Not sure I can help a lot here as I am starting to pack up for moving from California to a new QTH.? The XYL is "strongly" encouraging me to disassemble my lab as its the biggest eye sore for potential renters or buyers.? The best I can try to do is find out why the obvious "button" to stop TX and allow the radio to go into CW practice mode was never implemented.? I suspect as I dig into this, I will find a cryptic comment about "had to disable this feature to support xyz"...? But from your further discription sounds like this has nothing to do with your problem... There was another HAM? a few weeks back that was trying to add in a specialized CW filter and it required some changes to the code that drove the Si5351. You might search back through the prior positing and see how far he got.? I suspect what he was trying to do is at least in related area. 73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040, Teensy 4.0, and Raspberry Pi Pico https://github.com/aj6cu |

I have to backtrack on that "bug".? Everything appears to function as expected. STOP prevents any TX (no relay clicking in). Interestingly, it does light the TX light on the Nextion like it was really in TX mode. But without that Relay switching it is not.
However, it does look like the code assumes that the default value of a variable is Zero (never assigned before using...)? Got me thinking about why doesn't bootinto SDR mode work..... Need to review the code a little more... At the very least, the Nextion shouldn't pretend like it is going to TX and make the TX light red.... Maybe that is the only bug... 73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040, Teensy 4.0, and Raspberry Pi Pico https://github.com/aj6cu |
