David, The switch is for power On/Off, not for choosing the power source. The unit should draw power from the battery pack until another power source is plugged in via the barrel connector. My battery

Mitch, The “power switch” switches between the internal battery pack and the external power supply (I think). I put batteries into the battery case inside and mine wouldn’t work even though

HFSignals web page: http://www.hfsignals.com/index.php/antuino/ has a brief description.? Also, Ashhar posted a pdf of the basic schematic in message #63028 . (

The jre are just the runtime packages. Sounds like you need the development packages. If Symantic is installed on your system, run it in sudo mode.

Check your mic element connection polarity. Raj

If power out on CW and SSB are both low then the PA gain is lower than expected or something with filters. Raj

Bah! Humbug! Same difference. Do I have to have the raduino plugged in and the 'Board' selected? There has to be someone here who has used the Pi to load the CEC firmware. ??? Dex, ZL2DEX

Found jdk. Trying that.

Thanks Keven. Look like full java needed. jre not enough. Wilco. :) Oops, no 'java' package-have to delve for an appropriate armhf package? There's all sorts of 'stuff' in the repo. Like Jake The Peg,

Raspberries run linux. You HAVE to use sudo to install anything because that gives you root access. Type 'sudo apt-get update' Then follow it with 'sudo apt-get dist-upgrade'. That puts your OS at the

Just noticed a load of java errors. Not upgraded? <raspberry> me! Not even installed! Sort of essential, no? OK, in goes jre. Reboot. Try again, same difference. HELP!

Please be gentle. Raspberry Pi 3B, sudo-updated and upgraded, installed Arduino. Noted no icon on desktop: should I have done that non-sudo? At terminal, git clone from CEC's web-address as

That's a pretty good explanation, thanks so much.? It explains it exactly what I needed to understand.? Tim highlighting the regulator and looking up the datasheet had me look up the datasheet

Just found posts on Antuino and it being a spectrum analyzer

Where did you find the glc LIB? There seems to me many versions around. A link would be handy glenn vk3pe

Any reviews? Even descriptions would be nice. tnx jer aa1of

The switch is a simple ON/OFF switch, enabling power to pass into the circuit from the battery pack / DC barrel jack (since they're wired together).? The battery only works when something is not

So starting at the Barrel/Battery pack connectors we go through some 1v4148's as Reverse Polarity detection. From there we go to a switch which turns off the Antuino when running on battery or the

$21 for an all metal enclosure is pretty good in my book. Yeah, Nextion displays cost a bit more than parallel or even I2C touch displays but they're a full computer running your UI for you. Makes
