A–1 Part A Introduction 1 PT-8000 SERIES OF TRANSCEIVERS - CHARACTERISTICS 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.

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 This sign indicates an important explanation or a specific advice which should be obeyed An additional information or explanation is indicated this way

B–2 Part B Installation 3.3 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. 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. Picture 1

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. 5.2 Rear Panel Electret Mic Dynamic Mic

C–20 Part C Installation And Operation Because the operator should be aware of some major functions whether they are active or deactivated certain push buttons incorporate a LED: MEM MENU CHANNEL METER DATA FILTER LOCK NOTCH RIT/XIT NR TUNE AGC START SCAN 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 working in the background (green MAIN-RX LED is on) or • SUB-RX is active and MAIN is working in the background (yellow SUB-RX LED is on) • 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. 9 MAIN- AND SUB-RX OPERATIONS Picture 24 MAIN RX and SUB RX

PT-8000 A·B·C User Manual C–21 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) 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 the PT-8000´s MAIN-RX is the active one. • LED MAIN-RX and LED SUB-RX indicate which RX is the active one • The Display shows in the upper left corner MAIN or SUB • Frequency, mode, filter bandwidths are displayed for MAIN and SUB respectively Activation of noise blanker, DSP, DSP-notch and the squelch marker are displayed for the active RX exclusively. Picture 25 Settings from RX which is in the active one Settings from RX which is in the background Picture 26

C–22 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. 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. Example

The control enables to tune in 10 kHz, 100 kHz and 1 MHz increments. Pushing the knob activates the STEP-VFO function: • A curser appears at the 100 kHz digit of the frequency display. Turning the knob will now tune the VFO by 100 kHz steps. Pushing the knob a second time will move the curser to the 10 kHz digit. Turning the knob will result in tuning the VFO by 10 kHz steps. Pushing the knob another time will display the curser under the 1 MHz digit – hence tuning can now be established by 1 MHz steps. Pushing the knob again will result in a movement of the curser again to the 100 kHz digit, then 1 kHz and 1 MHz again. Neither pushing the knob nor turning the control for more than 3 seconds will terminate the STEP-VFO function. If re-activated by pushing the knob the cursor will be at the place used at last. When power up the PT-8000 the curser will initially alway occur at the 100 kHz (default value) position when activating STEP-VFO. Picture 44 Picture 45

C–40 Part C Installation And Operation 11.6 VFO Management Both receivers (MAIN- and SUB-RX) have its own VFOs – VFO A and VFO B. Switching between VFO A and VFO B is established through VFO A/B pushbutton. The button is located in the cluster VFO. In addition to the frequencies the VFOs store the filter (bandwidth) and mode information. When pressing VFO A/B: • In case the VFO softkey menu is already displayed the respective RX will change its VFO (A=>B or B=>A). • If a different softkey menu is displayed the first push of VFO A/B will call up the VFO softkey menu. The second push will alter the VFO A an VFO B. • Both frequencies displayed for the active RX will alter its position. The white display always shows the selected VFO. The VFO can be identified through the red nominators A/B. • The smaller green display always shows the alternate VFO that is not selected and in red its identifier. Only the SUB-RXs selected VFO frequency is displayed without its identifier.

C–42 Part C Installation And Operation 11.7 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 PT-8000 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.

PT-8000 A·B·C User Manual C–43 RIT/XIT menu / RIT/XIT offset Tune MAIN-RX to the desired transmit frequency to call a station that works split. Engage RIT and tune RIT to receive the station you want to call. The offsets for XIT/RIT are limited to 9.999kHz. 11.8 RIT / XIT RIT (Receiver Incremental Tuning) allows to shift/adjust the receiving frequency plus/minus 9.999 kHz from the transmit frequency. The MAIN-RX and the transmitter are no longer „transceive“. RIT is only possible with the MAIN-RX. XIT (Transmitter Incremental Tuning) allows to shift/adjust the transmitting frequency plus/minus 9.999 kHz from the receiving frequency. The MAIN-RX and the transmitter are no longer „transceive“. RIT is available with the MAIN-RX only. The tuning range of RIT/XIT is always plus/minus 9.999 kHz When pushing RIT/XIT located in the cluster VFO: • RIT/XIT-LED will be on • The RIT/XIT softkey menu will be called up - RIT or XIT are displayed inverse to show status • CLAR control is enabled • RIT or XIT and the offset is displayed right next to the frequency In case of RIT only the display will show the actual frequency resulting from the RIT offset. During XIT always the receiving frequency will be displayed. The status RIT or XIT will be shown in the display together with the offset adjusted.

C–44 Part C Installation And Operation When activating RIT/XIT the last used status (RIT or XIT) will be selected. Pushing RIT/XIT again will terminate the RIT/XIT function. To adjust the offset frequency turn the knob called CLAR (clarifier) located next to the cluster VFO. The tuning increments of the CLAR control is identical to the selected STEP rate. RIT/XIT are not available for SUB-RX. In case the SUB-RX is the active oneXIT/RIT and the offset are no longer displayed. In case the SUB-RX is the active one and XIT is activated for the MAIN-RX, pushing PTT will display the MAIN-RX as the active one. XIT and the offset are indicated. If the RIT/XIT softkey menu is displayed pushing RIT/XIT will terminate this modus. If the menu is not displayed pushing RIT/XIT will call it up and a second push will terminate ROT/XIT operation. The RIT/XIT-LED will extinguish. Changing MODE will always terminate RIT/XIT operation 11.9 LOCK Function All controls that will have an effect on the frequency selected can be locked through pushing LOCK which is located in the cluster VFO.

PT-8000 A·B·C User Manual C–47 13 FILTER BANDWIDTH AND SHIFT FUNCTION (WIDTH/SHIFT) Filtering in the PT-8000 is obtained by Roofing Filters (1st IF @ 70.7 MHz) and Channel Filters (2nd IF @ 10.7 MHZ). The channel filters can be further enhanced by a DSP (Digital Signal Processing) working in the audio range. The DSP filtering will: • Interpolate between analogue filter bandwidths • Sharpen the filter flanks • Shift the placement of the filters Acitvating DSP filtering is accomplished by the pushbutton FILTER in the cluster called DSP. If DSP filtering is engaged, FILTER-LED is on. After power on the DSP filters are off (Default value). Appropriate roofing filters are selected automatically WIDTH and SHIFT control located in the cluster MODE is used to adjust the filter bandwidth and to shift the passband across the spectrum. Pushing the knob will toggle between WIDTH and SHIFT function. In case the FILTER-LED is off only the analogue (Xtal) filters are active. The selected bandwidth is dispayed and graphically expressed. The position of the passband relative to the carrier frequency (represented by a vertical line) is indicated as well. Pushing FILTER button will activate the DSP. Additional filter will enhance the overall filter response: FILTER-LED will be on The display will indicate DSP operation Depending on the MODE there are analogue filters available which are interpolated in bandwidth by the DSP. Pi t 58Picture 59

PT-8000 A·B·C User Manual C–49 14 NOTCH / NOISEREDUCTION / NOISEBLANKER 14.1 Notch Filter Functions Two Notch filter of different type are available in the PT-8000. One is working at 1st IF 70.7 MHz – it´s the classical type of manual notch filtering using a Xtal bridge – the IF-NOTCH. The other one is part of the DSP – it´s an Automatic Notch Filter (ANF) – here called the DSP NOTCH. DSP NOTCH and IF-NOTCH may be engaged simultaneously. Notch filtering is not available in AM and FM. In case NOTCH filtering is active and modes are changed to AM/FM both NOTCHs will cease operation. After power on both NOTCH filters are off (Default value). 14.1.1 IF-NOTCH The IF-NOTCH will be activated by pushing the control IF-NOTCH which is located as depicted. On the display it is outlined as NOTCH 2. • The display will show NOTCH 2 • Turning IF-NOTCH will adjust the varable notch through the passband hence the interference will be almost nullified. 14.1.2 DSP-NOTCH Pushing the button NOTCH located in the cluster DSP will activte the automatic notch filtering. On the display the DSP NOTCH is outlined as NOTCH 1.

C–52 Part C Installation And Operation AGC menu Picture 71 The AGC (Automatic Gain Control) is active after power on, its hang time is 2 seconds (default value). Manual control of the AGC system is initiated through the AGC pushbutton located in the cluster FUNCTION. AGC-LED is off during standard operation. Pushing AGC will call AGC menu • AGC-LED will be on. • The AGC softkey menu will be called up: Select AGC hang time 3 sec Select AGC hang time 2 sec (default value) Select AGC hang time 1 sec Select AGC hang time 500 msec Select AGC hang time 100 msec The key toggles between RF-AGC / Audio-AGC (see below) To prevent missing of weak signals during tuning the MAIN- or SUB-RX AGC hang time will be always 100 msec. 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. AGC is derived from the audio to overcome situations described above. Normal operation is RF-AGC.
