While your decoder may scan, it could happen that it connects to fewer than usual number of bouquets it usually does. In some cases, such as where a single LNB signal is shared by two decoders, it can be corrected by disconnecting the other decoder. MRP40 is an Amateur Radio software program to receive morse code via soundcard, it allows to transmit morse code from the keyboard. This is usually associated with low signal strength to the decoder and can be rectified by dish realignment. I connected the DFU USB port to my PC running MRP40 morse decoder software that copy perfectly after just a couple of seconds of speed setup. Sometimes too, the decoder takes too long to scan and after scanning may experience picture cracks or signal disconnection on some channels. The red LED is flashing in absolute synchronism with CW signal and the speed (after some time) is closely locked to actual speed. You can verify if the fault is from the decoder or the LNB by connecting another decoder to the same signal or the decoder to another verified signal. The LNB is the device on the front of your dish that receives microwave signal from the satellite, amplifies it, converts it to a lower frequency band and sends it down to the decoder.

It may also occur in the event of cable disconnection between the decoder and the LNB (Low Noise Block) or a faulty LNB. MRP40-SDR also can transmit morse signals via I-Q output. This could be as a result of a change in the dish position and is rectifiable by having the dish re-aligned. In certain situations, the decoder searches for signal on various frequencies, but fails connecting to any bouquet. Another problem common to decoders is scanning difficulties.
