 DRM compatible cable splitter  installation  

Universal downmixer unit  from  455 KHz or 10,7 MHz to 12 KHz  (input of a PC- soundcard), designed for modification of existing AM- broadcast receivers to be able of DRM- receiving by use of the softwaredecoder from Fraunhofer Institut für Integrierte Schaltungen  or other softwaredecoders. Dimensions of the board 20x20x6,5mm. Oscillatorfrequenzy  eligible  467 KHz,  443 KHz or 10,712 MHz.  Power supply 7 to  20V. Current consumtion  < 6 mA . Optional crystal  467oder 443 KHz instead of LC; then   8,5mm high.

You want to adapt the tuning algorithm or want to create a customer own, please ask for well commented sources of our tuning software. This could be helpful in fast implementation of customer specific systems. N

New! MIXWNew!   Supports following digital modulations: SSB, AM, FM, CW, BPSK31, QPSK31, FSK31, RTTY, Packet (HF/VHF), Pactor (RX), AMTOR (FEC), MFSK, Hellschreiber, Throb, Fax (RX), SSTV, MT63.

DRM-Discoverer    Now the latest version of DRM- Discoverer from Carsten Knuetter tunes  the DRT1. So You can tune comfortable out of  a transmitter table also by use of the Fraunhofer Softwareradio and all other software, that is not able to tune the DRT1. Also a easy step- tuning (1, 5,9 or 10 kHz steps) is suported ( I use this together with DReaM in the AM- Mode).

DREAM   Best AM, good DRM demodulator. AM demodulator supports DSB, USB, LSB CW and FM mode. Also selectable bandwidths. DRM demodulator includes measurement utilities. A  *.dll for HAMLIB that also supports tuning from stations dialog is implemented.

IFDSP by IK2CZL , good CW and SSB demodulator with software AGC, AM demodulator sounds not so good. 

SDRADIO by  I2PHD and IK2CZL, practic skin, made for für I/Q direct mixing concepts, demodulates also by set an offset of middle frequency to 12 kHz single  12 KHz IF very well.  SSB, CW and AM demodulator.   

Attention !  Refer to the laws of Your country, in some countrys also for 1mW radiation power a transmitting licence is needed !
