ii Precautions / Content

Important

Read and save this Operating Manual carefully before attempting to operate the HF/VHF PT-8000

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.

NEVER apply AC to the DC socket (13.8V and 100V for PT-8000 B) 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-8000 A/B 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.

AVOID placing the transceiver against a wall. This may inhibit proper air circulation and could cause

overheat.

USE CARE when connecting the transceiver to a linear amplifier. Set the PT-8000 A/B 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 T-9 microphone. Others may have

different pin assignments and connecting to the transceiver may cause damage to the transceiver and

the microphone.

For U.S.A. only:

CAUTION: Changes or modifications to the PT-8000 A/B not expressively authorized by

Hilberling GmbH could void your authority to operate this transceiver under FCC regulations

For Canada only:

This class digital apparatus complies with Canadian ICES-003.

Cet appareil numériqué de la classe est conformé à la norme NMB-003 du Canada.

ERIES

RANSCEIVERS

HARACTERISTICS

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 Part A Introduction

1.2 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 PT-

8000 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.
