Thanks.
I have an ASUS router, which I am not using, but I don't know if OpenWRT is available for it.
If you already have a router, this is an interesting option, but probably an OrangePi using PiStar (Raspberry Pi) is cheaper than a router

asus flashed Padavan firmware also can run mmdvmhost ,ssh it ,then just wget
http://www.taozhengbo.com/mmdvm/MMDVMHost ,
and chmod +x MMDVMHost ,and ./MMDVMHost , run
,also you need MMDVM.ini file you can copy some need file from pi-star raspi /etc,i will post MMDVMhost ramip files later,welcome to test on asus router.
don't need buy some router just use your old one ,router didn't need tf card ,so it is better then some pi.

Hello
do you think is possible to use the router GL.iNet GL-MT300N-V2 ?
Openwrt is already installed and it cost less than 23 € now
best regards

FYI
Many people have problems with RF induction into the USB cable when using Hotspot mode.
Fix is to use ferrite clamp on the USB cable and if possible connect the radio to an external antenna

usb cable design for rx mode for cps , low power tx operation,50mw-250mw,high power need turn ant to external ,or diy a short usb cable,or use Ferrite Beads Rings.

Yes.
Low power is OK.
Short cable would also be better than a long cable. Just cut a section from the middle of the cable and join it again.
