Standalone HF SDR receiver Malamute 0 - 30MHz AM / FM / CW / SSB / RTTY ........

Description

Autonomous SDR receiver Malamute in a fully assembled form.
The size of the case (box) is 120 x 90 x 75 mm.
There is a USB port connected to the STM32F407VGT6 microcontroller, which makes it possible to reprogram, interrogate the MK, or connect it to Logs to maintain a hardware log, in the case of using an SDR receiver on an amateur, monitoring station. Or observe the work of stations operating in digital modes with installed software on computers, laptops, etc.
It works in the continuous range of
0.5-30 MHz
, AM / FM / CW / SSB. Real-time spectroscope and waterfall, 48 and 96 kHz span.
For convenience, it will be distributed to all amateur and broadcast ranges. First amateur and then broadcast. Switching buttons in a circle. Display colors vary, depending on frequencies and ranges.
It is possible to listen in
FM
mode up to
70 MHz
. The specific limit value depends on the instance of the Si5351a synthesizer chip.
It is also possible to decode and display on the standard display the signals of
CW
and
RTTY
.
The power supply of the receiver is 9-12V. Current consumption - no more than 350mA.
And for the first time it is quite possible to listen to, watch the work of amateur, broadcasting and other radio stations working in
AM
,
SSB
,
CW
,
FM
.
This device can decode
CW
,
RTTY
modes and display the result on the indicator.
A wonderful "toy", which with its work can be compared with more serious developments!

If your plastic case is damaged during operation, or you want / can print with high quality, then 3D models of the case in STL format can be downloaded here:
I'll add it later !!!

This design is not a high-class reception device !!!
And to expect from his work of any high, the transcendental parameters do not follow!
The main objective of this project or design is to familiarize users / radio amateurs with the possibilities of microcontroller equipment together (in conjunction) and high-frequency, radio technique!
The structure includes only fully assembled, configured and tested in work !!!
The color of the receiver can be negotiated additionally by correspondence !!!
