Informations about additional DSP Software links      wanted !

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. 

New! MIXW New!   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 fr 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.   

BKPCSDR50A by G8JCF, good AM, best SSB and CW demodulator, also software AGC. Several filter and noise reduction equipment. Also recorder mode supported. New ! Latest version supports DRT1 tuning by mouse wheel  and also  optional shaft encoder !
