KL505 Broadband use:
The KL505 is designed for operation on the 10m Amateur radio band,
from 28.000MHz to 29.700MHz however the amplifer has useful gain
covering all of the bands from 160m to 10m, (See the diagram ‘Gain vs
Frequency’ on the previous page). The amplifier does not feature Low
Pass Filtering so it is essential if the amplifer is used on other HF bands
that a suitable Low Pass Filter is connected to the output in order to
supress the harmonic output of the band being used, to avoid unneccesary
interference and comply with current regulations which should be know to
the operator before use.
It should be noted that the gain of the amplifer increases somewhat on the
lower bands so less input power is required for the same level of output
power. Input drive should be adjusted accordingly in order not to
overdrive the amplifier, the input attenuator
]
may also be used to adjust
the drive level so long as the input to the amplifer does not exceed 10W.
We reccomend that the amplifer be driven with about 7W from the exciter
or optimum performance on the 10m band.
