Steps to set the internal clock on a Malachite SDR
« on: September 07, 2021, 2232 UTC »
The Malachite SDR has an internal clock that is displayed.  However, there are no instructions on how to set it.  I have
found how to set the clock by accident.  Here is how to do it:

Long press HARD button to enter the time setting, then rotate the volume encoder to increase or decrease the number, and press inward to switch which moves to the next entry value.   When finished, press and hold the encoder, and release it when the beep sounds.

I hope this is a help to others that have the Malachite SDR.  It is a nice receiver, but, the documentation for it is limited.

Have you been to this dude's site?      https://www.qsl.net/n9ewo/malahit.html      This is a very tempting receiver, indeed.
I was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

Thanks for reply.  I did look at the web site.  My version is a Chinese clone, but it has  registered software,  It works fairly well.  As far as the lack of dynamic range, I found enabling the Digital Mixer GR help to reduce the intermodulation products.   You also need to increase the RF gain a bit.  I am using my receiver with a 50 foot end fed random wire antenna.  I have no problem listening to Free Radio stations.'

The V3 in this format, with the speaker to the left, knobs at the right, is indeed probably the best of the clones at this point.  If you get the upgradeable version, the receiver can be updated to 1.10D which is the latest for the DSP-1 Russian Malahit receiver.  As usual, STM32 Cube is a bit challenging to figure out for the newcomer.  Sometimes, the update will proceed normally with a "successful" confirmation.  Other times you have to disconnect and reconnect, or restart STM32Cube.
