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

I am looking forward to receiving my Antuino :) I guess I would power it with rechargeable Eneloop AA batteries. I think that keeping the voltage at 8 or 9vdc would keep it without overheating if used

Chris, The power connecter leads have to be resoldered on BOTH sides of the PCB. The reason is that PTH has been drilled out wile fitting the socket. Raj

Damn. Guess I could have done that, too. Thank you! Chris

Just replace the Nano and see. While desoldering leave the pins on the Raduino board and remember to order a Nano without soldered pins. Use some help if you are not confident! Raj

Yer 9 volts 500ma should handle its operations just fine. Ed N7SNT

Hi, From the schematic you can see that the power input goes directly, and only, to an lm78l05acz voltage regulator.? The datasheet for that says it will take a maximum input voltage of 35VDC and and

Guess we need an #antuino hashtag. Thank you for the answer that it does NOT charge the batteries. Does anyone have the specs for the power input? Thank you, Chris Shaker KJ7BLE

Hi Christopher, The schematic shows that the ground connection for the battery pack comes from the power input jack and this becomes disconnected when a plug is inserted there.? So there is no

I appear to be having the same problem with my Antuino. It won't power up with the battery pack. I reflowed the solder joints. The diode appears to be operating like a Capacitor, ie - it conducts

I meant +1 to Evan's help, AND I am slow to post an agreeing comment that was in draft stage.

+1 on what Evan kindly said, but I'm slow to post.? Use version 1.2 for your V5 hardware. It should default to V5. You've already mastered most of the common stumbling blocks. But, before one of us

The CEC v1.097 is not compatible with the v 5 board.? You need the version 1.2 or higher Here is the Hamskey link: http://www.hamskey.com/2019/04/release-cec-firmware-v1200-for-ubitx.html 73 Evan

I have yet to purchase anything....from what I read, i think I'm going to have to study the project more closely, as there seem to many more options/addins than I realized. I appreciate the
