G3B11: What happens to HF propagation when the Lowest Usable Frequency (LUF) exceeds the Maximum Usable Frequency (MUF)?

No HF radio frequency will support ordinary skywave communications over the path
HF communications over the path are enhanced
Double hop propagation along the path is more common
Propagation over the path on all HF frequencies is enhanced

G3C07: What makes HF scatter signals often sound distorted?

The ionospheric layer involved is unstable
Ground waves are absorbing much of the signal
The E-region is not present
Energy is scattered into the skip zone through several different radio wave paths

G4A14: How should the transceiver audio input be adjusted when transmitting PSK31 data signals?

So that the transceiver is at maximum rated output power
So that the transceiver ALC system does not activate
So that the transceiver operates at no more than 25% of rated power
So that the transceiver ALC indicator shows half scale

G4B12: What problem can occur when making measurements on an antenna system with an antenna analyzer?

SWR readings may be incorrect if the antenna is too close to the Earth
Strong signals from nearby transmitters can affect the accuracy of measurements
The analyzer can be damaged if measurements outside the ham bands are attempted
Connecting the analyzer to an antenna can cause it to absorb harmonics
