IMPORTANT NOTE AND PRECAUTIONS
Important
Read and save this Operating Manual carefully before attempting to operate the HF/VHF PT-8000A
transceiver. This manual contains important safety and operating instructions for the transceiver.
Precautions
WARNING HIGH VOLTAGE! NEVER touch an antenna or internal antenna connector during
transmission. This may result in an electrical shock or burn of your skin by high-frequency.
NEVER apply AC to the DC socket on the transceiver rear panel. This will ruin the transceiver and
may cause fire.
NEVER allow any object touch any internal parts or connectors on the rear panel of the
transceiver. This could cause electrical shock and severe injury.
NEVER expose the PT-8000A to precipitation like rain or any liquid nor operate the transceiver in
excessively dusty or very humid environment.
NEVER allow children or any unauthorized persons to operate the transceiver.
AVOID placing and using the transceiver in areas with temperatures below -15°C or above +50°C. If the
environment temperature drops so low that the dew point is undercut, avoid operating before the devices
are dried completely.
AVOID placing the transceiver and the power supply against a wall. This may inhibit proper air circulation
and could cause overheat. Do not cover any air inlets and outlets at top, bottom and rear panel of the
devices.
USE CARE when connecting the transceiver to a linear amplifier. Keep in mind the performance limits or
operating ranges of electrical connectors and interfaces. Set the PT-8000A RF-output level to less than the
linear amplifier’s maximum input level to prevent amplifier damage.
USE CARE when not operating the transceiver with Hilberling T9 microphone. Others may have different
pin assignments and connecting to the transceiver may cause damage to the transceiver and the
microphone.

3.2 About This Manual
The PT-8000A represents primarily state of the art analog RF-design. However digital signal processing
and microprocessor controlled circuits add to this transceiver in a synergistic way. Hence, features and
functions can be easily improved and/or tailored to customer needs through updating the Hilberling
GmbH firmware using the USB interface (please have a look at Appendix A2).

In this manual the following signs and symbols are used:
The STOP sign indicates a warning that must be obeyed for safety reasons.
This sign indicates an important explanation or a specific advice which should be obeyed.
An additional information or explanation is indicated this way.
3.3 Notes On Locating
When selecting the place for operating the PT-8000A bear in mind the general limitation
concerning environmental conditions as outlined in the specifications and the cautions at
the very beginning of this manual (P. ii).
Always handle the PT-8000A with care –consider the weight of more than 50 lbs, please!
Please make sure proper air circulation. Do not cover any air inlets and outlets at top,
bottom and rear panel of the devices.
Choose the place of installation so that all connectors of the PT-8000A are reachable any
time.
Select a power outlet that is capable to handle the power requirements. Connect your PT-
8000A to a proper ground system –which is important for optimum operation of any HF
transceiver –especially when operating high power by using an external amplifier. In the
past, a ground connection to a copper water pipe was often used for this purpose. Recent
revisions to the National Electric Code has made this practice a code violation. Bear in
mind that modern supply water installations utilize plastic pipe –which do not function
grounding purposes. Never use a gas or electric pipe since the connection could cause an
explosion or electric shock. A good grounding system not only prevents electrical shock but
also helps to ensure trouble free operation and will diminish television and broadcast
interference (TVI/BCI).
For your convenience you might raise the front of PT-8000A and HN-8000 by unfolding and locking tilt
bails mounted at the front equipment feet into front position as shown on Fig. 1 (see next page).

PT-8000A Operating Manual v2.00.33 3
If a large resistance will complicate the unfolding, please spread the bail easy for hurdle the
locking nib to avoid damage of the equipment foot.
3.4 Antenna Considerations / Antenna Tuner
Standing wave ratio (SWR) may increase significantly when using an antenna outside of the specific
frequency range for which it is tuned. The final power amplifier will operate at peak performance only
when its load is resistive –i.e. the SWR is close to 1.0.
Therefore the PT-8000A is equipped with an automatic antenna tuner (ATU) which does not actually tune
the antenna. The ATU instead matches the feed line to the final amplifiers so they always “see” a SWR
close to 1.0. The ATU has its limits –tuning mismatches with SWR greater than 2.0 become difficult and
will exceed the capabilities of the ATU. Using a tuned or resonant antenna with 50 Ohm impedance at the
feed point for the specific frequencies is highly recommended. The purpose of the ATU is to ensure that a
resonant antenna can be used at the limits of the band selected with optimum performance of both PT-
8000A and antenna system.
Never try to hook up a symmetrical open feeder line (balanced, twin-lead, ladder line etc.) directly to the
PT-8000A. Instead use 50 ohm coaxial feeders only. The connectors supplied on the PT-8000A are all
Type N.
With the ATU it is acceptable to use a broadband antenna system like a log periodic or T2FD system which
trade wide bandwidth for an SWR ranging as high as 2.0.

5 POWER SUPPLY HN-8000
5.1 General Description
Each PT-8000A is equipped with its power supply HN-8000, which delivers 13.8 V DC @ 8 Amps internal
/ 5 Amps. external and additional 50 V DC @ 14 Amp. max., i.e. the overall performance is about 900
W.
Operating voltages from the mains can be in the range of 90 VAC to 260 VAC without any degradation in
output power. Only the efficiency will vary slightly. It complies with special regulations in some countries
regarding power factor compensation (PFC). The HN-8000 provides triple HF shielding and feedthrough
filters.
In addition the HN-8000 provides an auxiliary output 13.8 VDC @ 5 Amp at the back panel, e.g. to
deliver further shack equipment.

7.1 Introduction
Prior to any operation of the PT-8000A read this Operation Manual carefully
notably before activating the transmitter.
The PT-8000A will be delivered with the following presettings:
The preselectors of both RX are aligned and all data are stored in RX-
CPU memory which is buffered through a NiCd battery.
The transmitter is unlocked according to the band plans of that IARU
region (see Page 36) the PT-8000A is delivered.
The IARU region can be changed by software update.

Prior applying main power to the power supply HN-8000 please verify the
following points (7.2).
