I'm using a long wire with a 9:1 balun. The main reason I'm running the 9:1 balun is just so I can connect my antenna and ground leads to the terminals. I've loaned my WSPR desktop to a friend with 20 foot of wire that he threw in a bush. And he still was heard all over the world.

I want a 6 meter capable beacon too! Now that Solar Cycle 25 is peaking, it would be nice to be able to transmit on 6 meters. My dream ZachTek beacon would be 6 , 2 and maybe 440. That would go great with the HF ZachTek beacon I already have.

I won’t be using them on a balloon anytime soon. A drone is limited to 400 Feet in the US. The batteries are for drone flights.

I looked for the tty device and it wasn't there to add. Plus, I was already an admin user. The answer in case anybody else runs across this is to install the OSX Arduino driver from GitHub. https://github.com/adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver/blob/master/CH34x_Install_V1.5.pkg When installing the driver you have to go into the security panel under system preferences to allow it to install the unsigned driver. That fixed the problem and allowed the serial port to be selected from the WSPR_TC_Config program drop down menu.

I am running High Sierra on an Old MacBook Pro. I am running WSPR_TX_Config as an admin user but the only serial port I can access is the bluetooth one. When I run Win 7 on the same laptop the ZachTek WSPR beacon works on Com3. Is there a command I can execute in the terminal to fix this? Thanks!
