Valt volgens mij wel mee, ze gebruiken het zelfde front-end.
Ze gebruiken echter een andere adc. 16 bits met 160KHz in plaats van 12bits met 10MHz. Heeft een processor met touchscreen ipv een USB aansluiting.

Op rtl-sdr.com staat ook een leuk verhaaltje over deze ontvanger.
Ook zijn de schema's vrij beschikbaar. (software weet ik niet)

Hi All
Dit zijn de verbeteringen die tot nu toe zijn uitgevoerd.

1.0a:
- added S-meter calibration
- S-meter error has been fixed due to which previously signals above 59 + 20dB were not visible
- sound indication is entered during manual shutdown or touchscreen
- sound off indication is entered
- fixed frequency correction error (parameter F correct)
- introduced the function of filling the panorama - the FFT fill parameter in the HARD menu
- added turning off the touch screen with a long press on the sound encoder
- something in the little things

1.0b:
- added RDS reception in WFM - to enable RDS, you need to click on the waterfall field when receiving in WFM. RDS reception is only possible if the RDS level is high enough
- fixed bug of filter switching on additional board
- fixed error in msi001 settings - receiver at 50MHz goes through, without hole at 50MHz
- added a parameter to the hard menu - BEEP LVL - the volume of the tone when you press the controls
- some minor bugs fixed

1.0c:
- dsp filter settings are moved to the hard menu;
- added three operatively switchable filters - selection by means of a sound encoder;
- introduced deceleration of the encoder when switching pages band;
- introduced the deceleration of the sound encoder when switching the filter;
- minor fixes in the RDS part;
- in RDS mode added frequency markers 19, 38 and 57 kHz;
- minor improvements and bug fixes;

1.0d:
- fixed USB operation - USB was unstable on version 1.0c
- protection against false switching is made - when switching on, press the button 3 times within an interval of 5 seconds

1.0e:
- a possibly critical error has been fixed - there was an incorrect work with memory and there could be problems with data processing;
- added additional characters in the font, when displaying RDS and CW decoder information;
- corrected S-meter - now more accurate S scales;
- added the ability to indicate the signal level in dBm - in the HARD menu, the "Ind type" parameter. Readings are displayed to the right of the S meter scale.

1.0f:

Do the firmware update strictly in accordance with the instructions !!!
- introduced a stylized retro scale in the FM broadcast range;
- increased the degree of averaging of the S-meter;
- changed the frequency correction mechanism - now it should be more accurate and does not depend on the frequency at which the calibration is done;
- detected and fixed error of switching DFT 120-150 MHz;
- renamed the state of the parameters: "Enable" to "Enabled", "Disable" to "Disabled";
- fixed a bug when working with a step of 8.33 kHz;
- fixed error with receiver stuck at low supply voltage;
- added selection of clock frequency depending on the processor revision: revision Y operates at 465MHz, revision V - at 480MHz;
- reduced interference from the touchscreen;
- changed the frequency of the PWM backlight for a more complete range of brightness control;
- The error of saving settings in the Visual and Audio menus has been fixed - earlier settings might not be saved when they were changed;
- S-meter correction made when UHF is turned on
- made the mode of enabling and disabling the image of the panorama and waterfall - in the Visual menu the parameter "View Pan & Wtf. In this mode, the data in
the display is only clamped when changing the settings by the user. This reduces the level of interference.
- fixed a bug with step selection - the bug led to a frequency failure when choosing a step;
- added shutdown timer - in the HARD menu the Activity timer button;
- the switching mechanism is changed - one press at a time in three;
- in the Visual menu, the bug with the backlight of the "LCD Sleep" button has been fixed.

1.10a:
- changed the inscription on the splash screen;
- changed the inscription of the Vbat control option - Standart is replaced by Standard;
- at the request of the users, the sensitivity of the touchscreen returned - please do not complain about the possible interference, we were not supporters of this return :)
- changed the setting of the reverse encoders. This is now one option on the hard menu;
- added autosearch of stations for Retroscale in VHF FM;
- added the option step "<-NEXT->" on the Retroscale for transition by rotating the knob
from station to station (if available on the scale);
- added color selection (one of three) for Retroscale;
- added IQ swap option to the HARD menu - to solve problems with Chinese clones, in which I and Q signals are mixed;
- on the main screen the AGC adjustment is replaced by ATT;
- added a DC suppression adjustment function to the VISUAL menu - this is a hump in the center of the panorama.

1.10b:
- fixed error in the S-meter readings for frequencies above 30MHz;
- the panorama scale injection has been changed - now instead of x1, x2, x4, 160kHz, 80kHz, 40kHz are shown;
- in SSB the 100kHz step is excluded and the 25Hz step is added;
- the touchscreen sensitivity is lowered again :);
- added synchronous AM detector;
- the frequency at which the low-pass filter 500000 is turned on is increased to 540,000, for better suppression of signals above the frequency of 500 kHz;
- added Auto Notch filter to the Audio menu;
- stretched grunginess adjustment;
- added DSB mode - as a kind of SSB;
- added CW mode - as a kind of SSB;

1.10c
- improved graphical display of the spectrum
- improved optimization of algorithms, increased display speed, especially in WFM mode
- added the ability to determine the type of inclusion - one or three clicks. If PD15 (pin 7 of the RESERVED field) is open, then turn on by one press;
if this pin is shorted to a common wire, then turn on by three clicks
- the HARD menu has been improved
- changed battery indication - voltage is indicated over the picture
- added the ability to control user equipment using a discrete signal - PD14 (pin 8 of the RESERVED field)
- added a button for switching audio output in the HARD menu. It duplicates the audio output switch. Made by user request.
- added modes SAM-U and SAM-L
- added engineering settings to the HARD menu
- added automatic Notch filter in AM mode
- added saving of retro scale type
- changed the management of high-frequency filters at the input of the receiver
- fixed error during frequency tuning
- fixed bugs in automatic station search in FM mode
- added Pseudo Stereo function
- added "CCIR / JAPAN" Retroscale band selector to AUDIO menu
- respectively, added Retroscale for the Japanese VHF FM band 76.1 MHz - 94.9 MHz and 6 presets for different regions of Japan, agreed with Japanese users.
- Fixed a bug when canceling the autosearch mode for stations and when exiting the autosearch without saving the found one (refusing to save the found). In previous versions, in these cases, all stations that were on the scale before the start of the autosearch were erased and the scale became empty. Now, in these cases, the original scale is restored.
- the design of the regular end of autosearch has been changed, a table-grid of frequencies for found stations has been added, messages about the absence or the number of stations found have been added.
- autosearch is no longer dependent on the inclusion of the stereo mode and the state of the activated outputs to the speaker and headphones, it works in any combination of states, after the end of the search, the original state of the stereo mode is restored.
- in some places of the editing menu, the retroscales of the CANCEL key names are changed to EXIT, as they are closer in the meaning of the action being performed.
- Added a limitation on the number of stations on Retroskale - 69 for the CCIR band and 63 for JAPAN - as the maximum number with an interval between neighboring stations from 300 kHz and above.
- fixed minor bugs of previous versions related to preserving the color of the scales and saving the step type (50 kHz / NEXT) for each scale.
- reduced the speed of switching stations in the NEXT step mode.

Update from 07/26/2021 - the operation of the synchronous AM detector has been fixed

Alternatieve Firmware voor de Malahite DSP 1 receiver

#11 Bericht door jan-nl »

Verbeteringen tov de originele FW van de DSP 1

Update for the Malahite DSP 1 receiver.

Thank you for the FW_1_10c_r2_p firmware (had 1.10c before).
Encoders are working perfectly now for volume and vfo.
Scrolling band pages and changing tune step requires a lot of encoder rolling to get one step.
Have you noticed this on your hardware?

Yes I have the same behavior. The software uses multiple routines to read the encoders - again bad written software.
I've only patched the ones that are commonly used.

P.S. These issues have now been addressed in version FW_1_10d_r2_p

You should try it again Antonio. I have finally understood how the frequency step is set.
There are 5 groups of 15 steps and you can change between these 15 values (10kHz, 12.5kHz etc) for a particular mode.
For some reason the author decided that you need 10 encoder steps to change band pages and from one step to another
and he was using a floating point increment of 0.1 to get from indexes of 0.0 to 14.0.
I've changed that increment to 1.0 and both frequency and step setting with the bottom encoder now work perfectly on my clone.
For the other encoder (the volume) the code is a mess and I don't think I can enhance that part.

I haven't noticed any change for the frequency setting between patched 1.10c and 1.10d and I haven't done anything differently.
In patched 1.10d I've only improved the step change and the band page selection.
Volume encoder works fine for volume but for other functions like filter change it takes a lot of clicks.

Als je de alternatieve Firmware nog niet gevonden hebt stuur mij een PM
