Anvelina SDR transceiver by EU2AV

#1 Непрочитанное сообщение YL2GVC » 12 ноя 2021 23:20

Hello! This is my first post on this forum in English Smile
As you can understand here will be discusiion, FAQ, etc about EU2AV Anvelina SDR transceiver. If you want to follow history of this SDR TRX, check this thread: https://eu2av.ru/viewtopic.php?f=4&t=141 and use Google translate ;) but time by time I will publish news here as well.
Anvelina SDR are developed by Yuri EU2AV and he got very good parameters. Time by time there are folk who show interest to buy bare board of SDR, like ANAN 6000, 7000 or Orion for example. But real offers are rare and Apache Labs looks like do not plan produce bare boards anymore. There are not a lot of documentation about this project. Mainly it is distributed inside Russian speaking community. At this stage, this project needs to be advertised on English speaking comunity ;) Author has extra PCBs. There are two of them. Main SDR PCB consist two ADC, thats mean DIVERSITY!!! There can be used mainstream LTC2208. But with LTC2217 it will goes around 6th-8th place in Sherwood list!!! There are some rumors, that after newest modifications it will goes to even higher place One ham made deep tests on this SDR board. It is named Anvelina Pro III, newest version. Even most biggest problem right now, are lack of ICs and other parts on market :-/ But possible source for parts are Aliexpress At least for BGA. It was possible to get it there for reasonable price, but now prices skyrocketing. And a lot of fakes :-/ Actually BGA soldering are worst part of this project. But as from feedback, on newest versions of boards with gold immersion, it goes much easier. Just these boards are more expensive.
You can check his Youtube channel: https://www.youtube.com/channel/UCeNlKE ... &flow=grid
Author show method, how to solder BGA. If follow all directions, even newbie can do it by himself
As well as, you can check neighbor thread: https://eu2av.ru/viewtopic.php?f=4&t=141
You can find HiRes pics of boards there. Not a problem to use Google translate. For skilled ham there shouldn’t be problems to build it up without help from side. But not all are like such a skilled.
I will try to help about this project, so much, how I can ;)

I am very curious about your reports on construction and component procurement. As already said, I would like to get involved in this project, but the current problems with the components let me refrain from doing so for the time being. But of course I will read along here as well.

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.

A small comparison in terms of current consumption, on the first board there is a good thermostatic generator with it, the total consumption came out to 970ma, in the second case it is a conventional generator 7N-10,000MBP-T =680ma
