Sainsonic AVRT7 iGate

For the past few months I have been having a love hate relationship with a Raspberry Pi Model B and Direwolf. The software runs perfectly well on my Pi3 but makes my other Pi fall over relatively easily. When this is at home it is no problem at all. I just reset and it will restart the software but the trouble is it has been at the clubs QTH. Ok I can log in remotely and deal with it but when it refuses to connect to the internet it becomes a pain. So I was looking for alternative solutions.

I came across the Dorji DRA818v module a little while ago and though that would work. It is a simple module that just needs a PCB and some connections to the Pi. But hang on, there are PCB’s you can already buy. But they don’t have filtering. Now hang on again there are those with filtering too. Now that looks good. Then hanging on for a third time the Sainsonic AVRT7 does it all simply!

So, now there are a bunch of choices for the same module. I’ve ordered a AVRT7 and around 30+ working days later I should receive the new toy.

There are a few warnings about counterfeit Prolific chips and trouble programming. I can see some frustrating times ahead but I’ve never been one to shy away from a challenge. I just hope it’ll be one that can be beaten. I will also get myself a SV1AFN pcb when I get around to it for home / experimental use. Just don’t tell Mrs g7kse!

Whilst we are on the subject I am really impressed with Direwolf. WB2OSZ has produced a really great bit f software that is easy to install on that Raspberry Pi and RTL Dongle you bought that you’re not using. The world can only get better with loads of iGates 🙂
