I guess, we need a better post mix amplifier? probably increasing the current there will help? I am not sure where this non-linearity is coming from. I suppose at least 70 db of linear range will be

I had experienced two cases of random errors. The first when I did not solder correctly the two resistors. The other when the jack contacts were not doing a perfect contact. Note that I am not using a

Looks like that 256 bytes of EEPROM is not a typo :(, it says the same at https://www.microchip.com/wwwproducts/en/ATMEGA4809 73 Goran VE6GPO

Yes...mini usb. Just to confirm the raduino is ok. Then, we can go after the wiring and main board

How do I hook up the 5v directly to it? Is it the miniUSB? I verified that all the pins are lined up for all connectors. With the power on, I verified that I have power to main board using the black

To answer my own question.... Yes, it will work! ?Connect everything in parallel as Lee explains, *Including* routing the yellow wire on the second display through the second nano's DS9 pin. Works

Use your dvm to verify continuity fron dc input to the board, power off just use ohms setting. Its easy to misinstall raduino one pin off in the connector. Patiently look for a simple cause. Curt

Pic of your wire up? If u have a cable, plug the raduino to 5v and make sure it fires up on its own.

I'm not sure. I don't have my kit yet (due in Thu) to do a closer inspection. [email protected]> wrote:

I couldn't see exactly what he did in the video. Is there somewhere else that I have to run a ground wire other than the black and brown wires on the 2 pin connector? I'm using a plastic case if that

Ensure you have your antenna jack grounded. At least that's what the Ham Radio Crash Course podcast found - he did a live build during the podcast: https://www.youtube.com/watch?v=ZJRak2571Sk

Hi everyone, I just built my uBITX kit, but it won't turn on. So far I have been able to check voltage at the power jack and the volume pot. Is there a guide for checking the radrino or other parts?

Mark QSL - I will have to read out of general interest on the v4 solution with ND6T.? honestly I like the VK3YE solution, its a third option for AGC but a road less traveled here.? as for the v3 and

Kelly let's not keep score on misteps - I might be pretty high on 'errors' also.? I am doing okay using the ubitx on cw with a straight key - it is enough to calibrate us this is not a QSK rig.? but

Kelly, you might want to use Dr. Lee's memory manager and in that you can specify at what point the adc ( from your front panel readings) will trigger a dot, dash or alternate between dot and dash.?

Dale, hello. I may be able to help out. I too had that problem at first on this mod. I have two questions for you. First, did you load the raduino firmware that ended with "_S", which denotes the

Farhan, I tried a the mod you suggested and bypassed the IF stage. In my case I removed the coupling caps on either side of the stage (C27 and C11), and soldered a new 100nF coupling cap between them

Yes, please. I would appreciate that! Again thank you Sam. 73, Kelly KD5AJ

I had no power up on mine .found two reasons 1 battery holder not making contact on + battery tips and cold a solder joint from external DC input jack and battery cable header .Best to reflow these
