Flexradio Flex-8400 with ATU SDR transceiver

Flexradio Flex-8400 with ATU sdr transceiver

with the series} 8000 (consisting of the models 8400, 8600, 8400m and 8600m), flexradio establishes the next generation of high-class SDR transceivers. The { flex-8400 is based on the architecture of the lucky Flex-6400, but has a CPU with performance about four times higher and an FPGA with double performance. This increase in performance not only guarantees shorter start and loading times, but above all it constitutes a solid base for the implementation of numerous future features that cannot be made with the resources of the Flex-6000 series. {

one of the first of these innovations is the "adaptive pre-drilling" (APD) which, according to the manufacturer, offers the cleanest signal on a radio amateur platform. All Flex-8000 models are also equipped with integrated GNSS (Global Navigation Satellite Navigation Satellite Navigation) and an integrated NTP time server as standard. This guarantees that all Flex-8000 transceivers always remain exactly on the same frequency. But even without a direct vision of the sky, the Flex-8400 can continue to use the internal TCXO. {

Receivers are designed as direct scanning SDR receivers. A 122.8 MHz sampling frequency is used; The AD converter has a word width of 16 bit. The result is an exceptional 115 dB RMDR value (with a spacing of 2 KHz). As a visible result of this high -level digital technology, the user has a mirror amplitude up to 7 MHz, more than enough to simultaneously observe different radio amateur bands and direct their activities accordingly.  {

The receiver frequency range extends from 30 kHz to 54 MHz, while the transmitter is limited to radio amateur bands.The pre -selector with 3 -pole band filters guarantees excellent immunity to large signals. Both receivers can work simultaneously on any band and in any operational way with instantaneous QSY between the VFO. The flex-8400 transmitter offers a transmission power of 100W (PEP, 25W AM), the suppression of unwanted by-products is better than 60 DBC.

the transceiver flex-8400 sdr of Flexradio has been developed specifically for the most demanding radio amateurs who want to use the radio from a PC, a laptop, mac or an iOS client, both locally and remotely. As an option, the Master console is also available, which can access the transceiver via WLAN or wired ethernet. As with all Flexradio transceivers, attention is paid to the practicality and simplicity of remote control.

There are two completely independent receivers, an important prerequisite for working on the right or to observe other gangs and other ways in a contest. Full Duplex crossband operation is also possible.

distance operation

each flexradio model, with or without front panel, It can be easily controlled at a distance. The following options are available:

• {
• SmartSdr software on PC Windows {
• Smartsdr for iOS on iPhone or iPad {
• Master Consul

Remote control can be carried out through the local network of the house, but also via the internet from a great distance. It doesn't matter where you are: you can control the rare DX station from your station, even if you are sitting in a hotel! With the latest V3 version of the Smartsdr software, it is even possible to make a transceiver work with two operators simultaneously. You can use any combination of the aforementioned devices: a PC, an iPhone/iPad or the master console.

Since the power supply is at 13.8 V cc, the operation is not limited to use as a fixed station, but also benefits from the freedom to be able to use the device in the car, van or camper.
