The Malahit team has made a change in the SMA cable – whereas before an extremely short length of wire attached the antenna to the PCB board, there is now a longer, though it appears even thinner, length of wire making that connection. From February you can also expect an optional additional board where reception on 6ghz is possible with additional filters. A 16 bit ADC will also be built into the Malahit DDC from February.

I also bought it with a view to using it as a piece of test equipment for locating noise sources with a WD8DSB mini-flag antenna. At 3.6 volts current draw is 9 mA. The signal levels are very similar as with the original mini-whip at 12 V / 55 mA.Something the pc can actually see if I disconnect the usb cable, this wording “STM Device in DFU mode” disappears. I understood that the problem is because “MALAHIT RECEIVER DFU” does not appear but “STM Device in DFU mode”.

Sensitivity and selectivity are surprisingly top drawer; I am hard pressed to find much difference between my IC-7300 receiver and the Malahit-DSP. Performance in the ham bands is excellent as is in the AM broadcast band. LCD connected to PCB with 3 times longer then original flat cable, making radio noisier from digital signals getting into RF and waterfall looks lot busier but reality is – it just own noise.

The capacity of the ADC. I will go into this characteristic in a little more detail. Very often the ADC bitrate is used as a marketing ploy that is misleading the user. It is logical that the more the better. But as we see, even with a 14-bit DDC, a better dynamic than 16-bit DSP. And that's why not only the ADC capacity is important for classic or analog SDRs, but also the properties of the ADC radio path. If you use 24- or 32-bit ADCs in the Malachite DSP series, the radio receivers do not get any better - MSI001 does not allow this, in which case it limits the connection. So, you need to carefully analyze the build of radio receivers and not trust misleading promotions - many bits are certainly good, but you shouldn't forget the location of the ADC either. The main properties of radio receivers are determined in particular by the first input stages. These upgrades show again that the Malahit team is serious about improving the current DSP-2 model, though it’s clear development continues for new hardware that will likely be available in coming months. The result: indeed the numerous noise spikes that are seen so prominently when using the receiver with a whip antenna, indoors or out, seem to disappear or become subsumed in the noise floor of the receiver.
