ASSEMBLED
transverter with
highly stable
frequency synthesizer
.
This allowed us to obtain a long-term stability of
0.2 ppm
and to extend the operating range of the transverter
222 - 224
MHz
with your HF radio frequency
21 - 23 or 28 - 30 MHz.
This model has
2 LO frequencies
that can be easily switched using jumpers on the transverter board -
194 and 201 MHz.
This allows you to use HF radio with frequencies
21 or 28 MHz
.
High frequency stability allows you to work in FM, SSB, CW and even
digital modes FT8 JT65 and etc
.
In this transverter model we have added an
additional input
for external frequency synchronization
. If you need very high frequency stability, you can feed a
highly stable 10 MHz
frequency to a dedicated transverter input. In this case, the stability of the frequency of the transverter board will be determined by the stability of the external 10 MHz generator.
This transverter specially developed for severe conditions of reception - contests, DXing, the neighboring powerful broadcasting and amateur stations. The mixer is made on special HI-frequency
ADE chip
with whopping dynamic range
IP3 + 17dBm typ
.
Transverter includes
everything you need
to use in conjunction with a HF transceiver with output power of 5-10 watts. Contains the input attenuator and the switch of the bypass on the HF antenna. In the
bypass mode
, the permissible power is
100 watts
.
When turning the
transverter power on
, the
HF antenna is turned off
and the transverter output is connected. The PTT control of the transverter is automatic with RF power or
or external forced closing to ground (switchable). Also, both modes can work simultaneously
.
We are offering completely built and tested in UR3LMZ lab assembled transverter that comes with the
English description
which contains the circuit diagram of this transverter and diagram of how you can connect to your HF radio.
