Problem

Possible Cause

Solution

No or poor UHF signal when in line of sight of repeater or transmitter.

You may be in a dead-spot where a direct signal is cancelled out (out of phase) by a reflected signal.

Move by approx. 1m - this should be enough to bring the two signals into phase.

NiCad battery going flat quicker than normal.

The battery may have developed a 'memory' from not being discharged fully before recharging.

Discharge battery fully (refer to equipment manual for discharge cut-off voltage) then recharge fully. You may need to repeat this process a few times.

Poorer than expected signal strength from an HF transportable.

- No or poor earth on a travelling wave long-wire antenna.

- Ensure the earth element of the antenna is properly earthed, preferably in damp earth, or unpainted metal.

- Antenna not pointing in the optimal direction.

- Orient antenna in the direction of the receiving station.

- Incorrect frequency (HF frequencies are affected by distance, time of day, seasons, solar activity, etc - see our Tech Info page for more details).

- Consult a current HF prediction chart for the appropriate frequency for the time of day and distance of the receiving station. Use beacon calls to test predicted frequency plus frequencies either side.
