John
Sarma,
Thank you for the suggestions. My problem has been solved with the exchange of the nano (now on headers as I have room). I have also used screened cable to the encoder and had to decouple the push button at the nano due to rfi on Tx sometimes triggering the menu. I might also decouple the encoder. What maximum values capacitors can you use for decoupling? Regards, John (VK2ETA) |

There may also be algorithm issues with the keyer in the stock firmware.

Updated firmware from Jim Sheldon or Ian Lee as posted to this group could help. Or use an external electronic keyer. On Thu, Feb 22, 2018 at 12:47 pm, Nik VK4PLN wrote: Change the CW key to using D0 and D1. You will need to add header pins and modify code... |

Re: uBITX working, question about power, PTT pop, LOUD headphone output

The problem with CW on the stock uBitx is not enough pins into the Raduino to do?
toggle quoted message
Show quoted text
everything we want it to do.? The uBitx uses a single pin for hand key, paddle dot, and paddle dash, those all drive that one pin through a resistor network, the Nano reads an analog voltage and decides which is happening.? Contact resistance can quickly get in the way of this scheme. Here's the code, down in ubitx_keyer.ino? from?? ################################### //reads the analog keyer pin and reports the paddle
byte getPaddle(){
? int paddle = analogRead(ANALOG_KEYER);
?
? if (paddle > 800)? ? ? ? ?// above 4v is up
? ? return 0;
?
? if (paddle > 600)? ? // 4-3v is dot
? ? return PADDLE_DASH;
? else if (paddle > 300)? ? //1-2v is dash
? ? return PADDLE_DOT;
? else if (paddle > 50)
? ? return PADDLE_BOTH;? ? ?//both are between 1 and 2v
? else
? ? return PADDLE_STRAIGHT; //less than 1v is the straight key
}
###########################
Here's three possible solutions: There has been new firmware developed that frees up digital pins by moving from the parallel LCD display to an i2c version of the LCD, so can use separate digital lines for paddle and handkey. Perhaps someone else here can recommend a specific firmware version that works well for CW use. Use a single digital pin, the firmware treating it as a hand key, could be driven from an electronic keyer. But I believe the pin will have to be moved, as A6 is analog only. Or use the stock firmware, but drive the single analog line with a small circuit board using 2n7000 FET's, taking in separate digital lines from your paddle or hand key.? ? ?/g/BITX20/topic/7709984#37057 ?/g/BITX20/topic/7791181 Jerry On Thu, Feb 22, 2018 at 11:55 am, Kai Nilakari wrote: I like to operate CW but hand keying is impossible due to sending errors which I get whenever I try to pound brass. |

Re: ubitx keyer
Hi,
got my transceiver the other day. It is now built in a metal box and seems to receive well although there is no AGC I guess? Operating CW is difficult. Have operated CW for decades but now I don't want to try it with uBitx because I get keying errors. Or the rig makes them, not me. What do you suggest? There must be a s/w bug which makes the errors, strange delays, too short or missing dots. Kai, OH3WE |

We are continously producing now, however, we are not able to meet the demand. Hence, the backlog still remains. I am hopeful that into early march, we will get past the backlog and start shipping ex-stock.? ? I am not very active on the mailing list these days because I am heads down, making test jibs, documenting the test procedures, writing arduino code to automate as much as we can. I hope to wrap it up and get back to homebrewing by the end of this week after handing over these jigs and software to the HF signals folks. Some of this stuff is quite neat and of interest to regular builders as well. i will post these circuits and code shortly. ? - f ? On Thu, Feb 22, 2018 at 11:01 PM, Gary Shriver <gshriver@...> wrote:

Re: uBITX working, question about power, PTT pop, LOUD headphone output

Hi Jim,
I also got the kit from India the other day. I have built it in an ex mobile vhf rig aluminium alloy case. I am not satistied with the transceiver due to the drawbacks you mentioned. I like to operate CW but hand keying is impossible due to sending errors which I get whenever I try to pound brass. Polished also the contacts and tried different keys, too. Nothing helps. Haven't tried SSB because I bought this rig for portable CW operation. Tonight I even updated the fimware. Got some new items to the menu but CW is still miserable in spite of the update. How about "hard" keying of the transmitter? Carrier on all the time and using a PNP transistor as a switch. No hazzle with processor loops or similar. 73 Kai OH3WE Lahti, Finland. |
