TR 144 H +40 with HF-Transceiver FT-757GX
When connecting the FT-757 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 850
When connecting the TS 850 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 850 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 850 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!

When connecting an externally supplied 8-12 V DC to B+,
the relay in the unit will be activated and 0 to 10 dBm will
be provided to A during transmission.
Please note that even during the absence of the voltage,
the antenna connector will still provide power output
during transmission.
