Flat audio (9600baud G3RUH) data port from SP/MIC?
Posted: Wed Apr 10, 2024 10:05 am
Hi all,
I have a question and/or suggestion on how to make the UV380/UV390 the go-to radio for the digitally oriented Amateur Radio operators.
I’m curious, would it be feasible to make “flat audio” analogue mode available on the UV380/390 models?
From my understanding, high-cut filter, low-cut filter and emphasis/deemphasis is done via DSP in the chip, and can be switched off. This info comes from talking in Matrix with one of the developers from the OpenRTX.
There was only one handheld radio that I am aware of that had this ability, the Kenwood TH-F6A in US and the TH-F7E for European markets. It had the ability to set the SP/MIC connection to Data, and then to select the 1200buad, or the 9600 baud (which was the flat audio setting). This made it a very versatile radio. It is no longer in production, unobtanium, and prohibitively expensive when you do find it.
If this is to be implemented in the MD UV380/390, it would make it the only one to have this ability, and make it very versatile. A ham operator can use one device for DMR, AX.25 at 9600 baud (G3RUH), Vara FM WIDE, 4FSK AX.25 (like MMDVM-TNC and NinoTNC are developing), M17, etc.
I’m a cash strapped ham, and I can’t afford a radio for each functionality. This would be very useful and I’d go and buy the UV380 in a heart beat. Any chance this is possible and would be done?
