Hig Performance 2 m Transverter
Several decades of engineering and production of Transverters result in t is new designed ig
performance Transverter TR 144 H +40. Its outstanding tec nical data make it usable for many
applications. T e transverter was originally designed for VHF amateur radio applications, for example
ig performance contest stations. T e receive pat of t e transverter provides very good large-signal
performance. T e new design of our transverter for 144 MHz features better performance and many new
functions.
Now, an external 10 MHz reference
frequency can be connected to ac ieve
ig est frequency accuracy. T is is
necessary for EME and WSJT. T e
frequency of 10 MHz can be supplied by a
ig ly stable OCXO, a reference oscillator
of a frequency counter, a rubidium
frequency standard or a GPS controlled
frequency source.
T e new design includes t e “old” options 02 (TX IF input power 60...1000 µW / 0...-12 dBm) and 06
(common IF-connector for RX/TX). So t e Transverter is compatible to most of t e used HF transceivers
wit transverter output. T e TX IF input ranges and t e IF connector configuration can be done wit t e
internal switc es of t e transverter. T e “old” option 04 (drive gain control on t e front panel) is
standard now.

TR 144 H +40
Oscillator
A temperature-compensated low noise butler oscillator generates the 116 MHz LO signal. A thermostat crystal with a 40 °C
precision crystal heater is used. Phase noise of the output signal is -1 6 dBc/Hz @ 10 kHz. This value is better than that of
the HF transceivers. The oscillator output power is 100 mW.
Receiver
In the receiver frontend there is only one balanced super low noise stage with two Power GaAs-FETs. A noise figure (NF) of
0.9 dB and an output IP3 of min. 40 dBm are achieved. To prevent interference in case of multi-band operation, there is a
notch filter for the 70cm band at the input. The prestage is followed by a high-Q helical filter and a matching network. A high-
level triple-balanced GaAs-FET ring mixer with an IP3 of min. 3 dBm converts the signal to the intermediate frequency (IF) at
28…30 MHz. The total gain of the receiver path is limited to 2 dB to avoid overdriving of the HF transceiver. An internal
preamplifier of the HF transceiver has to be switched off. The transverter provides excellent large-signal performance. Gain
and sensitivity are ideal for contesting and DXing. For EME operation the use of the preamplifier MKU LNA 144 A is
recommended. This drops the total noise figure to 0.3 dB. A second N-connector permits the use of a separate cable for the
preamplifier.
Transmitter
In the transmit path of the transverter a second 17 dBm ring mixer is used. The TX IF input power ranges (0.06 … 1 mW and
1 … 0 mW) can be set with an internal switch.
The TX gain of the transverter can be adjusted with the potentiometer on the front panel. For further power adjustments the
HF transceiver can be used. At the mixer output there is a matching network and a helical band pass filter. It is followed by an
MMIC amplifier stage, another helical band pass filter, driver amplifier and power amplifier. LD-MOSFETs are used in driver
amplifier and power amplifier. The available output power is 60 W. To achieve optimum intermodulation performance, the
output power is limited to 2 W. Overdriving is prevented by an ALC circuit. The transmit unit of the transverter has a
protection circuit. If the antenna SWR is bad, the power amplifier switches off for 3 seconds. This is indicated by a LED. A
final low pass filter guarantees spurious and harmonic rejection of more than 60 dB. The output power is indicated on a
calibrated meter.
Sequence Controller
The built-in sequence controller allows time-controlled operation of a high-quality power amplifier and a coaxial relay with a
preamplifier, which is placed directly at the antenna. The required connectors are on the rear panel of the transverter.

1 Connect the control cable. Please follow the description in the handbook of your HF transceiver
2 Connect a suitable antenna or a dummyload (power meter) to the antenna connector.
3 Open the transverter by removing the top cover (4 screws).
4 Set "CON SW" and "TX IF SW" compatible to the HF transceiver.
(see "Internal Switches CON SW / TX IF SW")
If needed:
- set the switch for pin 2 (see "connector wiring")
- change the receiver input to a separate input connector
6 Connect the HF transceiver.
7 Connect a 13.8 V DC / 8 A stabilized power supply to the transverter.
8 Adjust the output power of the HF transceiver to maximum (after having switched the transceiver to
transverter operation).
Important: The HF transceivers TS 8 0 and YAESU FT 1000 provide a distorted ("unclean") output
signal to the transverter if the power is adjusted to maximum. We recommend to adjust the power to
minimum by turning the power knob CCW.
9 Switch the transceiver and the transverter to transmit; adjust the transverter to 20 W transmit power by
turning the "TX power" control. The output meter of the transverter may be used for this step. When in
SSB mode, a tone should be used to drive the transmitter to full output; a CW carrier would be
preferable. Replace the top cover after the adjustments.
10 Almost all HF transceivers feature the option of continuously adjustable output power.

Informationen zum 10 MHz Referenzeingang der DB6NT-Transverter
Es besteht die Möglichkeit den Transverter an ein 10 MHz Frequenznormal (Referenzfrequenz) anzuschließen.
Wird eine externe 10 MHz-Quelle angeschlossen, so wird automatisch auf PLL-Betrieb umgeschaltet. Die
Frequenzstabilität ist nun von der Referenzfrequenz abhängig. 10 MHz können von hoch stabilen OCXOs,
Referenzoszillatoren von Frequenzzählern, Rubidium-Frequenznormalen oder GPS-gesteuerten
Referenzquellen eingespeist werden. Die externe Referenzquelle muss eine Ausgangsleistung von 2 bis 10
mW an 0 Ohm liefern. Steht keine 10 MHz Referenzfrequenz zur Verfügung arbeitet der Transverter mit der
Frequenzstabilität des eingebauten Quarzoszillators.
Nach Einschalten der Versorgungsspannung dauert es ca. Minuten bis der Quarzheizer QH40A
seine Betriebstemperatur von 40°C erreicht hat, dann ist der Transverter betriebsbereit.
An external 10 MHz reference frequency can be connected to the transverter to achieve highest frequency
accuracy. When an external 10 MHz source is connected to the transverter, the internal PLL will automatically
be activated. Then, the frequency stability depends only on the reference frequency. The frequency of 10 MHz
can be supplied by a highly stable OCXO, a reference oscillator of a frequency counter, a rubidium frequency
standard or a GPS controlled frequency source. The output power range of the external reference source must
be in the range from 2 to 10 mW on a 0 ohms load. If no 10 MHz reference frequency is available the
transverter works with the frequency stability of the built-in crystal oscillator.
At the beginning, when the supply voltage is connected and the transverter is switched on, it takes about
minutes until the QH40A has reached its operating temperature. After heating up the transverter is ready for
operation.

Some examples of transverter configurations

TR 144 H +40 with HF-Transceiver FT-7 7GX
When connecting the FT-7 7 GX with the transverter all modification instructions in the HF-transceiver manual must
be observed. Very important is the removal of the wire jumper which disables the power amplifier.
TR 144 H +40 with HF-Transceiver TS 8 0
When connecting the TS 8 0 with the transverter all modification instructions in the HF-transceiver manual must be
observed. Especially important is the provision of 12 VDC to the drive output which disables the power amplifier. It is
suggested to study the DJ 9 BV modification proposal published in DUBUS magazine 2/1992, page 30.
Important: By using the device Kenwood TS 8 0 experiences shows, that on maximum transceiver output power a
distorted transmit signal will be delivered to the transverter. We recommend to lower the output power to a minimum
(turn left) at this transceiver.
The IF OUT power of the HF-transceiver TS 8 0 is significantly higher at the beginning of operation. After some time
the internal temperature rises and the IF OUT power drops. Keep this effect in mind when adjusting the power levels
for transverter operation!

Beim Verbinden des FLEX-1 00 mit dem Transverter sind die Betriebshinweise im Handbuch des FLEX-1 00
zu beachten. Diese Kurzanleitung setzt voraus das Sie das Handbuch des FLEX-1 00 gelesen haben.
Die Kurzanleitung des SDR reicht für die Konfiguration des Transverterbetriebs nic t aus.
Für den Transverterbetrieb des FLEX-1 00 muss in der Software des SDR ein Transverter im „XVTR Setup“
angelegt werden. Dem neu angelegten Transverter muss im „Antenna Selection“ Menü der SDR Software die
Eingangs- und Ausgangsbuchse zugewiesen werden. Die soeben angelegte Transverterkonfiguration kann jetzt
als neues Band im VHF+ Bereich angewählt werden.
Unser Beispiel unten zeigt eine Konfiguration mit gemeinsamer ZF-Buchse für RX und TX. Andere
Konfigurationen sind auch möglich.
Des Weiteren sollte der Vorverstärker des FLEX-1 00 auf 0 dB eingestellt werden,
um die Großsignalfestigkeit des Systems voll ausnutzen zu können.
Alle oben genannten Hinweise zum Betrieb des FLEX-1 00 im Transvertermode sind ohne Gewähr.
The TX IF SW switch of the transverter must be set to position A, the CON SW switch must be set to position B
(see "internal switch CON SW / TX IF SW").
To connect the FLEX-1 00 to the transverter, please follow the instructions in your FLEX-1 00 manual.
Please read the whole manual of the FLEX-1 00 before configuring the SDR. The quick start guide does not
provide all information for transverter mode.
First you have to configure a transverter in the „XVTR Setup“ of the SDR software of the FLEX-1 00. After this
you have to set the configuration of the input and output connectors in the „Antenna Selection“ menu. Now, the
configured transverter can be selected as new band in the „VHF+“ area.
The example below shows a configation with one common IF connector. Other configurations are also possible.
Switch the FLEX-1 00 preamp to 0 dB gain to keep good large-signal performance.

TR 144 H +40 with HF-Transceiver TS- 90S
 The cinch connectors DRV and RX ANT are intended for transverter
applications. We don’t recommend the standard antenna connector (ANT 1 / 2)
for receiving because if there is a wrong menu setting there might be a signal
with W at this connector. This would destroy the transverter!
 Connect the transceiver with the transverter accordingly to the below-mentioned
wiring example.
 Do the menu settings as mentioned in the manual of the transceiver.
 Attention: For transmitting the key [METER (DRV)] must be pressed long to
activate the DRV connector. As soon as DRV is shown in the display the DRV
connector is used for transmitting. If DRV is not shown in the display there will
be an output power of W at the standard antenna connector (ANT 1 / ANT 2)
even if the menu is set to transverter mode! When activated there is a drive level
of about 700 µW (CW) at the DRV connector. We recommend to use the
transverter adjusted to the IF power range 1 … 0 mW (switch position B). If this
is too less drive power level to get sufficient output power from the transverter
the switch position A can be chosen.
 For receiving the key [ATT (RX ANT)] must be pressed long to activate the RX
ANT connector. Without this the standard antenna connetor (ANT 1 / 2) is
active. If the RX ANT connector is active RX is shown in the display.
 To control the transverter via the PTT signal the transceiver menu No. 3 (menu
No. 9 @ TS- 90SG) must be set to “2“ or “3“. This activates an internal control
relay of the transceiver.
 We recommend not to switch on the internal preamplifier of the TS- 90S to
achieve good large-signal perfromance.
 We cannot guarantee the coreectness of the description about the handling of
the TS- 90S.

TR 144 H +40 Schaltausgang / change-over output
Sicherung des Schaltausgangs (Pin 3 am Sub-D-Stecker)
Der Schaltausgang kann zum Umschalten eines Kurzwellentransceivers (z.B. IC7800) in den Transvertermodus
genutzt werden. Er liefert 13,8 V DC (12 ... 14 V DC), wenn der Transverter in Betrieb ist. Der Ausgang ist im
Transverter intern gegen Verpolung (Diode) und Kurzschluss (Widerstand) geschützt.
Reverse voltage and over current protection on the change-over output (Pin 3 on the Sub-D-Plug)
Some HF transceivers (e.g. IC7800) can be switched into transverter mode with a control voltage. The
transverter provides 13.8 V DC (12 ... 14 V DC) on Pin 3 when the transverter is switched on. The change-over
output of the transverter is protected against reverse voltage (diode) und over current (resistor).
