Important note regarding technical support and repair:
If you need technical support in usage or a possible repair need, please report your problems first in the Telegram channel. There the designer and some other users can be helpful. We believe that more than 90% of the problems are caused by usage and can be solved by the community. For more information, see "What should I do if I encounter problems?".
A ready to use device. Complete to enter the world of DUC/DDC. Brick3 SDR TRX by EU1SW is a 15 W HF transceiver for the shortwave bands from 160 to 6m.
DDC/DUC transceiver with Ethernet interface. The hardware developed by Linoobs. The firmware (gateware) for this transceiver is based on original Hermes and was modified by Sergey EU1SW and published here.
The receivers are designed as direct-sampling SDR receivers. The AD converter has a word width of 16 bits. This results in an excellent MDS value of -134 dBm (at 500 Hz spacing). As a visible result of this high-end digital technology, the user has a spectrum width of up to 384 kHz at his disposal. The frequency range of the receiver extends from 30 kHz to 60 MHz. A low-noise oscillator contributes significantly to the good receiver. A 10 MHz reference clock generator (TCXO) is available for exceptionally high requirements.
The power amplifier consists of field effect transistors RD16HHF1, the output power is max 15W in range from 160m to 6m, which is more than enough to drive QRP or pump an external power amplifier. 7 low pass filters for 160m-6m band and 1 high pass filter. Full frequency extension.
Separate 2 x 16-bit ADC, 14-bit DAC. Works with Thetis, LinHPSDR, Console and other control programs, Panorama 48-384 kHz, LNA, ATT, audio codec. SWR bridge allows to display power and VSWR in the program.
Well suited for transverters, thanks to the integrated TCXO the frequency stabilization is no worse than 0.1 ppm.
An gigabit interface is used to communicate with a personal computer and is operated in a local home network. Sound transmission and control works both on the device itself and remotely; no cables need to be laid other than the Ethernet cable; you can throw it in the attic and continue to use it at your workplace. With this transceiver you benefit from all the advantages of direct digital signal processing that are not possible with classic transceivers.
