Hi, All of the changes are covered in the changelog (see below). - The latest 4.2 beta firmware is compatible with the ATS25-AMP. - PSK decoding is supported. When the new firmware is installed, you will need to make sure you select the correct receiver type in the configuration, otherwise the recei...

Hi,
Without hardware modifications the bands shown are not available.
See the thread below for further information.

Hi Antonino, Thank you for the information. The circuit you have shown does not seem to be correct. The NPN transistors needs to be removed as per the example in your Github page. Mixer.JPG Mixer enable, GPO2 = Logic ‘1’ (3V3). N-Channel MOSFET ON, PNP transistor ON, Relay ON. The solid state versio...

This will not work automatically unless you come up with a different switching scheme for filters. The minimum that can be done is to switch manually to connect the mixer. Hi, All understood. It just seems strange that GPO2 was chosen for the mixer control if it is already being used for filter sel...

Hi, For interest, does the ATS25 Max Decoder II use GPO2 for its HF filter selection? The generic diagram generated for the mixer arrangement implies the following truth table. Mixer.JPG If like the ATS25-AMP, the ATS25 Max Decoder II uses GPO2 for its internal HF filters depending on frequency (i.e...

Hi,
When the radio rebooted after the firmware update, there should have been an option to set the receiver type.
You should be able to go into SETUP/CONFIGURATION/Choosing a model and then select the ATS120.

Hi,
Looking at the screen dump, there does not appear to be a COM port specified.
I may be mistaken, but if you run the batch file manually you will need to pass it the arguments for the ‘COM’ port and the ‘DISPLAY’ type.
Example: flash COM3 ili9341

Specifically a mixer, or SI5351? It's strange, somehow I don't quite understand the connection - modulation and mixer... Do you use it for demodulation in any way? For FM demodulation, the FMI input is used on the SI4732. Therefore for CB/10M NFM the input signal needs to be upconverted (using the ...

I have the same module as in the picture of the respected Darwin (download/file.php?id=161&mode=view). If I don't need to extend the range, but only want stability and accuracy of frequency setting, can I use the circuit from his post above ⇈ without any NE602 mixer? Device ATS25 max-Decoder II...

Hi Darwin, For the expanded frequency modification, both the SI5351, NE602 mixer circuit and associated RF switching would be required. The on-board crystal is connected between SI4732 (GPO3 - Pin 2) and (RCLK - Pin 13). When using the SI5351 for the frequency reference, the crystal would need to be...
