Part A Introduction
PT-8000 S E R I E S O F T R A N S C E I V E R S - C H A R A C T E R I S T I C S
Hans Hilberling, DK7LG, the founder of Hilberling GmbH and a veteran Amateur Radio operator and RF
engineer specified the design requirements of his “dream-transceiver”:
1. It must include a single high-quality transmitter with two independent receivers covering the
entire HF and VHF spectrum.
2. VHF operation must be an integral part of the design, not an afterthought. VHF performance
must match HF.
3. Its operational frequency range must be easily expandable through the use of transverters.
4. It must include independent sideband (ISB) capability.
5. The design must incorporate both analogue and digital signal processing, using the best of both
technologies.
6. It must provide high output power on HF through the use of modern, efficient HF-MOSFETs at
50 V (PT-8000A) and 100 V (PT-8000B) drain voltage .
The result is the PT-8000 series of HF/VHF-Transceivers featuring cutting-edge design!
1.1
Receiver (RX)
Each of the two identical receivers are double super-heterodyne Rx with 70.7 MHz 1st intermediate
frequency (IF) and 10.7 MHz 2nd IF. The PT-8000 incorporates high quality, state-of-the-art receiver
design, including:
1. An automatically tuned preselector which is a series tuned circuit from 1.8 to 30 MHz. The main
inductance is based on a T-200 toroid. Research has shown that the IMD characteristics
correlate with the mass of the material and the transformation ratio used. The IP3 of this
preselector is outstanding +50dBm. The series circuit is tuned through software by 5 inductor
taps (5 bit) and an 8-bit capacitor set. A noise generator is used to tune and store all settings in a
table. In order to enhance the filter characteristics the circuit is operating at approximately 3
ohms – there are down and up transformers at the input and output.
2. Precision-matched first and second mixers with third intercept points at +40 dBm. The mixers are
designed specifically for Hilberling by Synergy Microwave, a respected name in the industry.
3. Three 6-pole roofing filters at 2.7 kHz, 6 kHz and 12 kHz for outstanding inband IMD and BDR
performance.
4. Six hybrid amplifiers from LF to VHF with third intercept points at +50 dBm
5. The first local oscillator is designed with quadruple microwave VCOs which offer excellent phase
noise characteristics: -130 dBc/Hz at 10 kHz and –145 dBc/Hz at 50 kHz. The first local oscillator
design features microwave VCOs designed specifically for Hilberling. It includes a 0.05 ppm
reference oscillator with organic DDS. Phase noise suppression is enhanced by means of 300 Hz
crystal filtering.
6. The PT-8000 uses ultra-sharp 10.7 MHz IF filtering. The key to the receiver’s performance is its
seven 16-pole ladder filters working in combination with DSP filters in the 10.7 MHz second IFs
of each receiver. The filter shape factor is an excellent 1.3 at 2.4 kHz. The same high-quality
filters are used in the transmitter stages as well. 17 of these filters are used in the PT-8000.
A–2
1.2
Part A Introduction
Transmitter (TX)
The transmitter frequency scheme follows the receiver design. In addition, the transmitter is capable of
transmitting two sidebands independently (ISB-operation). For example, one can transmit an SSTV
signal on LSB and a voice (phone) comment on USB for example. The transmit power is 100 or even
600 Watts with enhanced filtering:
1. The PT-8000 transmitter stage starts with a Class-A 10 W driver amplifier operating from 1.8 to
150 MHz. IMD3 is less than –50 dB at 2.5 W.
2. The 100 W power amplifier utilizes a 50 V HF-MOSFET which is actually a “Gemini” package
hence comprising two HF-MOSFETs working push-pull (SD2932). This HF-MOSFET is capable
to dissipate 500 Watts and delivering up to 300 Watts output power. The PA of the PT-8000A is
limited to 100 Watts hence presenting a signal with outstanding IMD characteristics.
3. The 600 W final amplifier includes a pair of high-efficiency (70%) SD3933 HF-MOSFETs — a
breakthrough in transmitter design.
4. The PT-8000 assures clean output thanks to innovating filtering, including the use of additional
three 70.7 MHz roofing filters in the transmitter stages.
5. A diplexer-filter guarantees optimum performance of the finals. An automatic antenna tuner
(ATU) is an integral part of the output design. In terms of power handling capability of these
components there is no difference between the 100/600 W models.
6. For VHF operation (144 MHz to148 MHz) a 13,8 V VHF-MOSFET (RD70HVF1) is used,
designed to deliver 25 watts output.
1.3
Power Supplies And Growth Potential
The HN-8000 consists of switching power supplies with full power factor correction (PFC) as demanded
by many energy suppliers. It is capable of delivering up to 1,000 W 13.8/50 V DC-power for the PT8000 A. The HN-8000 designed for the PT-8000 B is capable of delivering up to 2,000 watts DC power
at 13,8/100 V supply voltage. Both power supplies are rugged in design and deliver ample power for the
PT-8000 series. The DC-input power can easily monitored with the large front panel power meter.
As your operating horizons expand and new demands occur, your PT-8000 will respond:
1. The PT-8000 is the ideal platform for exploring the world above 50 MHz. Not only does it offer
outstanding 6 and 2 meter transceiver performance, the PT-8000 is designed with UHF and
microwave transverters in mind. It offers 1 Hz frequency resolution and the ability to connect
transverters to both receivers simultaneously.
2. The PT-8000 provides output taps at the first and second IFs for analysis, monitoring and
experimentation.
3. The PT-8000 firmware is easily upgraded – as described in Part D of this manual.

About This Manual
The PT-8000 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 RS232 interface. Owners will be informed about firmware upgrades as they
are released – please have a look at chapter Part D.
The latest version of PT-8000 Operating Manual will be posted as a PDF-document at Hilberling GmbH
website (www.hilberling.de)
In this handbook the following signs and symbols are used:
The STOP sign indicates a warning that must be obeyed for safety reasons

Initial Installation Considerations
When selecting the place for operating the PT-8000 bear in mind the general limitation concerning
environmental conditions as outlined in the specifications and the cautions at the very beginning of this
manual.
Select a power outlet that is capable to handle the power requirements especially for the PT-8000B.
Connect your PT-8000 to a proper ground system – which is important for optimum operation of any HF
transceiver – especially when operating high power either with the PT-8000B or 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 PT8000 and the HN-8000 by unfolding and locking into
position the front stand under the cabinet as shown on the picture.
Picture 1
Allways handle the PT-8000 with care – consider the weight of more than 50 lbs, please!
3.4
Antenna Considerations
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-8000 is equipped with an
automatic antenna tuner (ATU) which does not actually tune the antenna. The ATU instead matches the
feedline to the final amplifiers so they always “see” and SWR of 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 feedpoint 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-8000 and antenna system. Never try to
hook up a symmetrical open feeder line (balanced, twin-lead, ladder line etc,) directly to the PT-8000.
Instead use 50 ohm coaxial feeders only. The connectors supplied on the PT8000 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.

General
Each model PT-8000 A/B is equipped with its appropriate power supply all named HN-8000. The only
difference in appearance for the PT-8000A-model and the PT-8000B-model is the final amplifier DC
input power instrument at the front panel.
The HN-8000 is a switching power supply with industry standard. It complies with special regulations in
some countries regarding power factor compensation (PFC).
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. The HN-8000 operating temperature is controlled by
up to 4 fans (PT-8000B). The HN-8000 accompanied with the PT-8000A and PT-8000B delivers 50 VDC
@ 15Amps and 100 VDC @15 A for the high power B-model.

MAIN RX

The PT-8000 incorporates a transmitter and two independent receivers (MAIN
and SUB). Both receivers are permanently operating. Even if a receiver is „in
the background“ i.e. not fully accessible through all main controls the receiver
is operating with its last settings when it has been the „active“ one.
One transmitter and two receivers are operated in three main modes:
•
•
MAIN-RX is active and SUB is
background (green MAIN-RX
or
SUB-RX is active and MAIN is
background (yellow SUB-RX

• TX is operating (red TX-LED is on).
Note: The MAIN RX VFOs will always determine the transmit frequencies
The red LED EXT REF will be on when the PT-8000 20 MHz system clock is
no longer the internal one. An external 10MHz signal is representing the
frequency reference when this LED is on.

The PT-8000 incorporates a transmitter and two independent receivers (MAIN
and SUB). Both receivers are permanently operating. Even if a receiver is „in
the background“ i.e. not fully accessible through all main controls the receiver
is operating with its last settings when it has been the „active“ one.
Two controls are doubled, hence for these functions MAIN-/SUB-RX are
always accessible regardless of their status:
1. The selected VFO of the RX working in the background is always
accessible through SUB VFO.
2. The volume of MAIN- and SUB-RX are permanently adjustable through
the respective controls MAIN and SUB.
3. Both knobs have a “push” function: Depending on the AUDIO setting
NORMAL/SPLIT the audio from MAIN and SUB are allocated to the
speakers and are turned ON and OFF (see page C42)
Picture 25
The push button MAIN/SUB (see picture 27 page C11) toggles between the
two RX changing their status „active“ or „background“. During initial start up

Part C Installation And Operation
When toggling between MAIN- and SUB-RX the actual settings of the controls
used at last are not transferred to the new active RX – instead the former
settings of this RX are the actual one – until they are overwritten by the
respective control.
Example
The squelch threshold set to the RX working in the background will stay the
actual one when this RX becomes the active – until one touches the squelch
control to set the threshold to a new setting.
The large S-meter is always allocated to the active RX. The smaller S-meter
is indicating the fieldstrenght of the RX working in the background.
Pressing PTT when SUB-RX is the active one will toggle MAIN- and SUB-RX
instantaneously. As mentioned before only the MAIN-RX can operate with the
TX as a transceiver.
When transmitting SUB-RX may be used to monitor own RF-signal. Receiving
with SUB-RX on a separate antenna is limited however: Excessive field
strength may trip the protection circuits. Receiving at frequencies adjacent to
the tranmitting frequency may be limited even by the superior dynamic
characteristics of the PT-8000 receivers - which are of course finite.

Primary means of tuning the active RX (Main- or SUB-RX) is the main tuning
knob.
General frequency coverage is 9 kHz to 54 MHz and 110 MHz to 170 MHz.
Due to the frequency scheme of the PT-8000 the frequency from 54 MHz to
110 MHz is blanked out.
Transmit operation is only possible on the allocated amateur radio bands (see
Tab on page C20)
In case the transmit boundaries are to be modified (commercial application;
new amateur radio frequencies) please contact Hilberling GmbH for further
information about a software update.

SPLIT Operation
There are various ways to split between transmit- and receive frequencies.
Keep in mind that the PT-8000 represents a transmitter with two identical
receivers. However, to link a receiver with the transmitter as a transceiver is
only possible with the MAIN-RX. Hence only the MAIN-RX VFOs can
determine the transmit frequency.
Three ways for SPLIT operation are available:
• Operating with MAIN-RX using SPLIT VFO
function
as
described
in
11.6.
This is the “regular” method which gives you
quick
access
to
the
desired
SPLIT.
This way the resources of the PT-8000 are used
economical.
• Tuning MAIN-RX on the desired transmit
frequency and using SUB-RX for receive.
This way you can listen to the transmit and to the
receive frequency simultaneously which can give
some advantages in difficult (crowded)
environments. However all resources of the PT8000 are used. The SUB-RX can not be tasked
with other valuable operations like band
monitoring, transverter operation etc.
• Using MAIN-RX and detuning RX or TX through
RIT
and
XIT.
The least elegant method. SPLIT is limited to
10kHz.
SPLIT Operation using VFO SPLIT function
Tune with VFO A to the station you would like to call. Select VFO B and tune
to the desired transmit frequency. Make sure the same mode is selected.
Reselect VFO A. Press SPLIT. Now VFO A is for receive and VFO B is for
transmit.
Of course you can tune with VFO B to receive and tune VFO A to the
(split)transmit frequency. Selecting SPLIT will always chose the alternate VFO
for transmit. Pressing VFO A/B will alternate RX and TX frequencies.
Pressing SPLIT again will terminate SPLIT operation.
The actual operating frequency in RX/TX will always be displayed as the
selected VFO frequency; i.e. during SPLIT the display will change with T/R
switching.
SPLIT Operation using MAIN-RX and SUB-RX
Tune with SUB-RX (either VFO) to the station you would like to call. Tune with
MAIN-RX to the desired transmit frequency. You can monitor the stations
calling and the station to be called simultaneously. This might give
advantages in crowded environments. Use the volume control for MAIN and
SUB to adjust convenient monitoring.
SPLIT Operation using RIT/XIT
Tune with MAIN-RX to the frequency of the station you want to call. Engage
XIT and select an offset that you desire to call the station.

To prevent missing of weak signals during tuning the MAIN- or SUB-RX AGC
hang time will be always 100 msec.
RF-AGC
The AGC-voltage is derived from the RF-signal after it has passed the
channel filters (10.7 MHz). The DSP will narrow the passband – hence out of
(DSP)- filter signals may still derive AGC voltage. This can be annoying
especially during CW operation. The solution is to switch to Audio-AGC.
Audio-AGC
AGC is derived from the audio to overcome situations described above.
Normal operation is RF-AGC.
