Re: uBitx v6 flashing
Hi Yvon,
The linked message from Gary Anderson pointed to a possible solution to your issue.? Here is the message content: Begin Message: ============================================================================================= Frank, Please post the errors. Most common problem is that you did not select the correct bootloader in the Arduino IDE to match the bootloader on your Nano. Tools-> Processor: -> ATmega328P (Old Bootloader) 100+ posts on this, that common. Rgds, Gary ==================================================================================================== End message 73 Evan AC9TU |

Re: uBitx v6 flashing
You mentioned you tried several Pc's. Normally I would suggest re rooting and making really sure nothing is using that Com Port. Win versions tend to hang onto Com Ports. Triple check. Swap cables as this may be common in your tests. Did you get a 500 error msg ? What msg if any did you get. Try removing the Nano from the socket then try and refresh.

uBitx v6 flashing
Hello,
I bought a used uBitx v6 that is off frequency by 3KHz on 20m and 1.5KHz on 40m and so on. I did download and compile the latest version but was unable to upload it to the Nano. I am using Win10 and 'Device Manager' sees the COM port so it is not a CH340 driver issue. Same issues on two different computers. I did remove and reinstalled the Arduino IDE with the same results. Otherwise the radio is working surprisingly well. Any suggestions would be welcome. 73, Yvon AE7YD |

Re: no usb or lsb - both sides are alwas on
Hmmm.? ?I've never tried it with Linux, so I don't have any particular insight there.? ?
The only other things I can think to check are on the tools menu of the Arduino IDE, that the Board is set to "Arduino Nano" and the Processor is set to "ATmega328P (Old Bootloader)". |

Rolan, The code seems to be good in both places I am using Linux, not Windows, if that will cause any problems.

Re: Output power display
Hi scttmtclf;
The sBitx DE does not have Power / SWR detection circuitry. It is not difficult to add this circuitry to the DE, and several people have already done this successfully. Look at the message thread titled "swr_bridge.ino"? - There are 60+ messages discussing the process, with the most recent messages from Scott KE8KYP and Juan WP3DN including photos of their -SUCCESSFUL- implementations. Perhaps the sBitx software should have some way of indicating that the Power / SWR detector circuitry is not available (when there's no response to I2C address 8) but the effort to add this detector to the DE is really not that great - especially if you have some Arduino experience. 73; Steve, N3SB |

Re: Output power display
Have you installed an SWP/Power sensor?? That was not included in the sBitx DE V1 radio.? You would need to build/buy a Stockton bridge and an ATTiny85 and wire them in.? Ashhar Farhan did say there would be a manual calibration method published for us DE owners that do not want to add the sensor.? I have not seen the instructions as of today.

Output power display
So On my sbix DE v1, i upgraded to the latest software version with a fresh sd card.? I am trying to calibrate the power output, and I am running into two issues.? The first is that with the drive set at 97, it puts out exactly 20 watts.? The second issue is that the power output display shows 0 watts.? So I am attempting to follow Ashar's instructions with metercal, but when I turn the knob, the power output display doesn't change from 0.? I have attempted to search this forum, but I am not finding anything.? Can anyone provide me with some guidance?

Re: Amplifier keying circuit ideas ?!
I use the Heil FS-2 foot switch with my Icom 7600 and my 8410 amplifier and I’d use it with my uBitx v6 if I wanted to use it with an amp but for me that would be conflicting with the whole idea of QRP. Unfortunately it looks as though Heil no longer makes the FS-2. Apparently there is a replacement model FS-3 but it’s only single channel. Perhaps the FS-2 could be found on eBay.

Re: v4 Setup issue
Thanks Evan, I did have the V5 firmware loaded.? Because of your directions, I found and installed the correct one.? The problem still exists, but I now have a clue of what the problem is.? When I push the switch to go into configuration, I am in the transmit mode and that's the reason for no audio, My guess is that I have a wiring error, not a software issue.
I think you have steered me to the right path now. Thanks again, Nick Cloyes - N4CL |

I've run the new software a number of times and it will not compile. The stock software gives me no change when changing from USB TO LSB.

Re: Amplifier keying circuit ideas ?!
The easiest way to key the radio and amp (I am doing this with my ubitx6) is to use the heil footswitch FS2. I did not want to do any wiring inside the radio.
It has two output cables with one going to the amp and one to the radio.?typical application is to key a transceiver with the black lead and an RF power amplifier with the red lead. Due to their design architecture, the micro-switch controlling the red lead keys up first as the foot switch is depressed. Thus, the red lead turns on before the black lead, ensuring that the amplifier is keyed first before the drive is applied from the transceiver that keys up last in the sequence.?On FS-2 switches, one keying cable terminates in a 1/4 in. phone plug and the other in a male RCA phono-type connector. This red phono connector is common to many the amplifier keying input connectors or an adapter may be used. This red lead that keys your amplifier can easily be fitted in the field with other types of connectors. The wire is easily soldered, should you need to remove the red phono connector. The other black keying cable terminates to a 1/4 in. male black phone plug. I used an adaptor to change the 1/4 inch plug into a 3.5 mm plug. I took the mic output 3.5 mm jack and plugged in a stereo 3.5 mm splitter and one arm goes to the mic and one arm goes to the foot switch. Make sure the you connect PTT and GRd correctly to the stereo three wire connector. Just a thought..... Good luck David W9PH |
