Remote Control:
The remote head is not supplied from RM Italy however the circuit diagram below shows the requirements
of creating a remote front panel if required. The connector is an RJ45 type and cable length should be no
more than 3m in length. The remote front panel controls offer the same functionality as the front panel of
the KL805.
The function of the pins present on the remote connector as as follows:
1.
Ground
2.
Preamplifier ON input
3.
Wattmeter signal output
4.
Power output for the remote command
5.
Hi power input
6.
Linear amplifier ON input
7.
Low power input
8.
SSB input
At no time should should voltage appear on pins 5 & 7 at the same time.
When using the remote control, the switches on the front panel should be set as follows:
Preamplifier OFF
Linear Amplifier OFF
SSB / AM AM Mode
Power set to Mid, (center), position.
The digram below shows the circuit diagram of the remote control circuit and pin out of the RJ46 front

Pin 8
Warranty:
The KL805 is covered by a 24 month warranty against manuafacturing defects, from the
date of purchase. The RF transistors, external and asthetic damage are not included in the
warranty.

KL805
The KL805 is a 24Vdc narrow band HF Linear amplifier covering 25-30MHz.
Maximum output power is 600W from 15W input power. It may be used in
AM,SSB,CW and FM modes of transmission. The KL805 features a independant
receive preamplifier that provides about 26dB gain for the received signal. The
diagram below and the front and rear panel descriptions on the following page show
how the amplifer should be connected. The KL805 features an internal RF switch
so when the linear amplifier is switched on, it will automatically switch to TX and
amplify the output of the transceiver when there is RF on the RTX input connector.
The KL805 features internal automatic VSWR protection and will shut down if the
antenna VSWR increases about about 2.5:1 protecting the transistors from damage.
It is also protected from excessive temperature that when reached will disable the
amplifer and increase the fan speed to maximum speed, automatically resetting
when the temperature falls to within the normal range. The KL805 is also protected
against accidental DC input reverse polarity.
