<html><span style="font-size:11pt"><span style="line-height:107%"><span style="font-family:"Calibri",sans-serif">Hello around, I would inform about interesting SDR project. It is developed by EU2AV. 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. Main problem are, that are mainly distributed inside Russian speaking community. At this stage, this project needs to advertised on English speaking comunity ;-) Author sell 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!!! One ham made deep tests on this SDR board. Author got very good parameters. It is named Anvelina Pro III, newest version. If anybody are interested, I can share everything what I have about this project on personal request. I made BOM for Digikey, but it is going to change very fast. 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 is possible to get it there for reasonable price, still. But 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.</span></span></span><br />
