There a lot of methods, how to determine are LAN chip work or not. If it will not get IP address, MAC address ...

Re: Anvelina SDR transceiver by EU2AV: how to build, solder, where to get parts, etc.

Hello Luca! Could you check oscillators output? One my board won't work, because 122Mhz OCXO got too low voltage. I do not remember, where the fault was. As well, did you check voltage on all IC's? What about KSZ9031, can you ping it, does it appear on LAN?

Re: Anvelina SDR transceiver by EU2AV

Right now there are problems, but it is possible to get over them 8-) Mostly there are skyrocketed prices on some parts :o BGA and KSZ9031 are most problematic part. It is possible to get on Ali, but big chance of fake :evil: As well for example LTC2217 in reality are LTC2208.
