Well here in my Duo 4K not (7.2 or 7.3) ... only if you don't "like" MSTIF ... then I test it on Uno 4K SE.
Like:
What has that got anything to do with a device working or not?
An MTSIF tuner can only be used on the Vu receivers with this connection socket on the circuit board. A USB tuner can be used on any receiver with driver/kernel support. As well as other devices.
It cost about £70. I bought 3 of the USB tuners for less than £20.
Yes, an internal tuner looks better.
These are the packages I installed
opkg install firmware-mn8847x
opkg install kernel-module-mn88472
opkg install firmware-dvb-demod-mn88472-02
opkg install kernel-module-tda18250
opkg install firmware-dvb-usb-dib0700-1.20
opkg install kernel-module-dvb-usb-dib0700
Here is a screenshot of it on a duo 4k on RC 7.3. If it is not working for you, post your install logs and dmesg messages.
