Hi. I am running mine on 13.8v with no problems. Murray ZL2IQ. ________________________________ Sent: Friday, September 6, 2019 9:29:42 AM To: [email protected] <[email protected]> Subject: Re: [BITX20]

Hello Chris, Do you mean both crystals on the Raduino proper and on the Nano's board? For comparison I do have birdies (mine is a V3) here and there as I have on my FT-817, albeit not as significant

Hi, Here is a thread where the person powered the whole uBitx from 15 volts and raised the output power substantially. This was an earlier revision, so should re-evaluate if any components on the new

Hi Jerry, I've thinked a lot about your post and here is a diagram of the setup I want to make on my rig : This setup gives me the possibility to choose on S2 weither to use an external PSU or not for

Rechargeable AA batteries are nominally around 1.2-1.25v, 6 of them would provide 7.2-7.5vdc. Would it be too low?

I'm actually working on the PCB to add the AGC mod and also a Smeter for my uBitx. I've choosen the VK2ETA AGC mod and the KD8CEC Smeter. Here is my schematic made with Kicad and the board which will

Hi all, whats your thoughts, while using wsjt-x for ft8 I have been noticing a peroid of not receive data on the water fall, until I click the tune button on and off. Then all works as it should.

No.. gonna try moving the radio.. it is a bit high noise in the spot it is in.. on my 450d it would be s5-s7

It sounds like an internal spur. Do you have the same thing on any other radios in that room? -a

I should add its there through all volumes, and is same with or without nextion firmware. relative to the earphones its not loud but noticable... Am I over thinking?

Ashhar: Thank you for designing the Antuino for us! Chris Shaker

Chris, here is the Antuino group forum on : /g/Antuino/ Garry

Another point of view is to stay with the standard LCD as it works decently. The color displays add appreciable power consumption. Someone with motor skill issues may do better with the standard unit,

The Antuino draws 0.080ma at 5v. With a linear regulator to 5v, the regulator is dissipating (12v-5v)*0.080 = 0.560 Watts. Much over 12v going in and the LM78L05 will soon overheat and go into thermal

Hi everyone, I am experiencing something odd, when tuning around on dummy load or no antenna/dummy load attached i hear a high pitched squeal that goes up in frequency as you tune a couple khz up

Thom Yes, it can be a a bit overwhelming the options for the build. We are adding the JackAl board and 7" screens. I also have a Bitx40 that I was planing to build as portable unit. Since new Ham's

https://n2htt.radio/2019/05/26/hello-antuino/ This gent says 9-12VDC, but the voltage regulator data sheet says it will take up to 30VDC.? Take note of the milliAmp rating.? It is low, so I'd stay

Adrien -- I did exactly this with a old 16v laptop brick power adapter. The 16v from the power adapter went direct (well, thru a fuse) to the brown wire, and direct to a? DC-DC down converter making

A 12v power supply is recommended. It draws about 80 ma of current when in operation. Most of it goes to light up the display. I didn't have any spare pin on the Arduino to turn the power to the

Raj: Thank you. I did actually resolder both sides, and used a solder sucker to remove the excess. I'll look at it again tommorow. It powered up and worked with a 12 vdc power supply. Chris Shaker
