Hello,  Rob
Yeah,  for Hermes Lite the price is pretty reasonable,  but not for Ody-2.

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 David,

I suspect that if we contact makerfabs in China and provide PCB, Part List and some support, they would probably be able to sell the complete product at reasonable price (guessing $700 with enclosure)

They fabricate Hermes Lite 2

You have to use the latest version of Bootloader FW and MCU FW. You can have up to 3 different working FW in this device at the same time, preffered to use the latest version but it is not important.
The latest version of working FW may have important opernHPSDR protocol updates.

I am current owner and user Odyssey-2 and if it becomes necessary to correct a mistake or modify something, I will do it very quickly.

Hi Reto,

Could you send me the Order List for Digikey and Mouser?

For BGA reflow, I plan using a Reflow Oven T962a ($300) and I think the smaller Reflow Oven T962 ($200) would work too.


You can also try ordering a stencil for the Odyssey2 from China. It costs $30 shipped but it took a month to arrive.

Here is the contact for the stencil (picture attached):

 Contact: nicole@...
 Order Number:SO200209123998-2916005A
 1 pcs $14.25
 Stencil issue 2916005A SO200209064
 Production file: Odyssey2-SO200209123998

Hello Maurizio

I only can help you with a PCB. In our group we build in the next weeks a Odyssey TRX. And I also can send you my Order List for Digikey and Mouser. The filter I ordered at mini-circuits in UK. And our kits are ready. There are many youtube videos how to solder the BGA. Also one from David. We have the same probem. How to solder the BGA. But I think it's possible. If not, you' may find a person near you, who is eqiped with the tools and can do this for you. 
I also looking here, because I have no equipent at the moment. If I find one who does it for us, maybe he can do it also for you and I can send you a PCB with BGA installed. But at the moment this is only a theory. Im searching for a solution.

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.

Hi Reto,

For FPGA soldering, in my case I set the hot plate to 240 degrees and
put it on the hot plate for about 3 minutes. Then raise the board up.
The point is to raise it so that it doesn't slip when you give it above.
Also, instead of placing the board directly, it is placed on a jig made
of aluminum plate and can be moved by hand.
I made two Odyssey and two Odyssey2. David gave me a lot of advice on
how to make it. Thank you very much.
I don't have a photo that I made soldering, but here is a photo after
soldering.

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 ;)

Hello David, 

A few HAM's from Europa (HB, DL and maybe some other countries) starts now to build an Odyssey II. We also made some PCB's from your distributed GERBERs and are ready to start soldering. Most of us never soldered a BGA before and we discussed how to do this or if it's better to search help from a professinal who made this before. All other soldering work is possible for homeworkers. 
We have the board revision from your Gerber files provided in git hub. I also read your forum and all the hints you gave there for building. Including some mods. 

Which firmware is the right one we should choose and which bootloader? 

Is the project really finished, or do you plan some firmware upgrades in future?

Buy Odyssey 2 SDR Kit

iz7wwy@...
 

Ciao 

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.

OK, nevermind, I have found the problem.

Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Hello. 
Unfortunuatelly the board is still silent. I don't know, maybe it has some mistake somewere. No any reaction to programming RFFC chip.
Here is sources of board, if you could help me to find errors or doublecheck my design at least.

Hi how about the new UHF board? Very much looking forward to seeing the new inverter board working

Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Hello,
it looks very promising. Soldering small smd components is not a problem, I have a microscope.

Now I have two SDR-Micron versions, one with ADS9629 and R820 BPF board and the other with ADS6145 without BPF board yet.
So far I will wait for the result of this Super VHF-UHF version board, then I would try to make one for the ADS version.

Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Hello, Radek
The R820 board was rejected form project.
I just received PCB from China and started to assembly new VHF board. Very small components, need to use a microscope.

Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Hello David,
any news regarding 50 MHz - 6 GHz extension board for SDR-Micron?
 
I noticed that the R820 extension board project was abandoned on Github.
 
thank you for answer

You can save more power using 1.8V DC/DC converter for ADC supply. 

Re: SDR Micron - 14-bit Direct Digital Conversion Receiver with USB connection

Yes, I am also worried about DC / DC interference, so I only use it on the 1.2V power supply of the FPGA. At present it looks like the frequency spectrum is clean
