transceiver is in the transmit mode (high current consumption).
• The antenna being too close to the equipment may cause a slowly oscillating buzzing
carrier heard in the receiver. A loose coaxial connector or a broken or missing ground
may aggravate this problem. Normally, these noises will be below the background or
“band” noise. RF feedback from the transmitter may create instability in the power
supply causing a poor sounding, raspy or unstable transmitted signal. A distance of 40
to 50 feet between the antenna and equipment is generally recommended for any 100
watt HF installation. Position the antenna as far and as high from the equipment as
possible.
• The power supply may turn off due to excessive transmitter energy being coupled into
the AC and the DC lines. Either your antenna is too close (less than 10 feet) or the
antenna system is not radiating properly. First check the antenna system SWR. Then, if
necessary, relocate either the antenna or the equipment further apart.
