Hi Rob, 

I can do that if it's in a aceptable layout. NOw I have the basket file of digikey, the mouser articles I have to add manualy. I'll put it here asap im ready with it. 

Stencil: I think I don't need it because I'll solder the parts manualy. But maybe I change my mind and "cook" the Odyssey in the oven ;) Because this will not be a speed built project I have time. Now all parts arrived from Mouser and Digikey. So most parts are ready to solder. I miss only the filter modules.

Hi Leo, 

Thanks for your answer. Yes, we stand at the total beginning. complex solderwork is normaly no problem, but BGA is the firt time, and before I kill a over 100$ chip I first make some prepeartions, and look arround how others did this work. It's completely no need to finish this project in the next days. I also thinking of buying a cheap BGP soldering "machine", because we built here several pieces because we are an international group of HAM's who built together since years. Most of them comes from the UHSDR project. We bult many boards and complete TRX based on the UHSDR software, but som with modifications or other formfactors. Also a very nice project and much easier than the odyssey, but also not for beginners. 
The last TRX I built is a Sparrow 4 Inch. Also very portable (formfactor of a KX2 from Elecraft), 20W output and all HAM Bands (6m only RX or very littel output, because the PA is not usable for 6m). There's a 4 Inch Touch Display with Waterfall and Spectrum and many other nice functions like built in FreeDV.

Hello David,

Thanks for your Answer. I wathced the Video, but don't understand you speaking ;) But I see the video and I think I have understand how to do it now. It seems impossible to work without preeheating plate. So I'll looking for any or for a cheap BGA station. maybe in future I'll need it more times.
The Odyssey project is very interesting and so we decided here to start this also, after a few years you present it. Because most infos are in russian language it was not quite esay to collect all information. BUt think google translate we also had a chance to read your Forum/website. Finaly I found this group here which ist in english.

now i think we can start the project. most parts are ordered at digikey and mouser. Some from other places, because not found at this two distributors.

Hope we have success with this project. It's the first time working with a BGA, and also building a direct sampler. The last projects are mchf based, UHSDR and also similar projects from SP3OSJ. Also very interesting stand alone TRX, but no direct samplers ;)

I met you recently while looking for hermes sdr. I would like a sdr with multiple receivers and I would also like to try the diversity mode. I think the Odyssey-2 may be the right choice. Is there a kit? Or someone who has one left? I have experience on manual smd assembly, it only blocks me BGA, and I can't find the right pieces.
