Usually when this happens, your messages are full. Delete some and you should be able to send.
Using the supplied LDG cable attached the red end (radio) in to the left most mic jack input on the back of the radio, then attach the black end of the cable (tuner) to the Radio port on the back of the tuner.
If you want the tuner to control the radio then update the Tuner Select property to LAMP (Linear Amplifier) in the FT-891 deep settings. Now when you press the tune button on the tuner it will lower the power and send a CW carrier to tune the frequency.
If you don't have cable the tuner will still try to auto tune when you transmit but it's sub-optimal. So you'll need to drop the radio's power down (below 35W, if you don't you'll ruin the tuner) and change the mode to CW by long pressing the BAND button. Then PTT and the tuner will perfomr a proper tune.
80M = 16 radials at 1/4 wavelength length = 2 wavelengths of wire
40M = 8 radials at 1/4 wavelength length, 16 1/8 wavelength length
It really doesn't matter try it out!

I've been having a hard time getting the Uniden SDS100 serial over USB to work with my Windows virtual machine, but finally figured it out.
My virtual machine setup
Using VirtualBox with Oracle VM VirtualBox Extension Pack installed. The first thing you'll want to do after installing the Oracle VM VirtualBox Extension Pack is to enable USB via the virtual machine's settings. I selected USB 3.0, but depending on your use case, you may have to try another option.
