Hi All.
Thanks for yours reply.

No time to answer , I am working under BPF board combined with R820T VHF chip.

Hi David


>I have a plan rebuild this board to combine BPF with a VHF tuner chip R820T2 used in known RTL dongles. It provide the possipility to increase the receive range up to 1.8 GHz.

What a nice project. I think the HF version could be presented as a « serious » starting platform for SWL and people wishing to put a panadapter in a bigger rig. Receivers are definitely not out of date. Just look at the incredible commercial success of the « Airspy » familly and other SDRPlay . You are targeting the same range of buyers, but with a strong « 14 bits » argument.

Just a stupid question : as your receiver is covering only the 0 to 10 meter bands for the HF baseband section, wouldn’t it be easier for you to simply stay compatible with something that exist already ? I’m thinking of the N2ADR board designed for the Hermes Lite V2

http://james.ahlstrom.name/hl2filter/

it only needs an I2C bus (and the RF path) and it’s characteristics are rather good for an smd based rf filter.

CuSDR can easily drive these filters with the hpsdr « J16 » parameters. The only drawback is the lack of software audio demodulation and the need for a local hardware DAC. A Linux fork of CuSDR did support the audio… I don’t remember who did this hack.

Quisk could also be a nice client. And hdsdr  or SDRAngel (https://github.com/f4exb/sdrangel) too

Hi David,

I ordered Micron SDR PCB immediately.
I noticed by looking at the BOM file, but I think M25P16-VMN6TP is
difficult to obtain due to discontinuation of production.
I found M25P16-VMN6TP that I had purchased as a spare when I made HiQSDR
mini before, so there is no problem.
I'm really looking forward to it.

Hello, people
I would like to meet you with my new design - small and cheap 14-bit DDC receiver with USB connection wich could be your next weekend's DIY project.
It has board size only 83 x 55 mm, you can order on jlcpcb.com just for 2 dollars.

Device is based on the cheap modern FPGA chip Cyclone 10,?10CL010YE144C8G with price less then 10 dollars.
ADC - 14 bit?ADS6142, ADS6143, ADS6144, ADS6145 or 12-bit ADS6122, ADS6123, ADS6124, ADS6125.
LNA - AD8099, attenuator 0 - 30 dB DAT-31 or compartibled.
USB chip - FTDI FT232HQ High Speed USB 2.0 connection, up to 60 MB/s
Clock generator is?5P49V5923, very cheap any freq clock source with a refference 10 MHz oscillator.
Output sample rate could be any in list:?48 kHz, 96 kHz, 192 kHz, 240 kHz, 384 kHz, 480 kHz, 640 kHz, 768 kHz, 960 kHz, 1536 kHz

Additional board could be installed as second floor and contains 5 Band Pass Filters wich avoid an ADC be overdrived by strong out-of-band signals. The frequencies of edges
0 - 2.5 MHz, 2.5 - 6.0 MHz, 6.0 - 12.5 MHz, 12.5 - 20.0 MHz, 20 - 30 MHz.

I have a plan rebuild this board to combine BPF with a VHF tuner chip R820T2 used in known RTL dongles. It provide the possipility to increase the receive range up to 1.8 GHz.

Both theese boards installed into standart aluminium Hammond case?1455C801.

Everithing connected with this receiver will be fully open, you can find the firmware sourcecode, PCB gerbers, manuals and many others on my Github page https://github.com/Dfinitski/SDR-Micron ( https://github.com/Dfinitski/SDR-Micron )

The most important thing for any SDR device is a sowtware of course. I have hired professionals programmer that made for this receiver ExtIO.dll. Thanks to him, receiver can work for now with HDSDR, SDR Sharper, Zeus Radio.
Watch this video with the first successfull work
https://youtu.be/paRoJstyToo

https://youtu.be/2bdUQClitkQ

Inspired by this victory,?I imagined that in the same way it would be possible to make the receiver support in amazing opensoused SDR programms like CuSDR, ExpertSDR, SDR MAX.
CuSDR is of particular interest because it has an excellent wide bandscope.
For each programm implementation I will need to pay at least 200 - 300 dollars to programmer and it is very expensive for me unfortunually, given that there is still a lot of work on the hardware part.
I thougth that user support by donation could solve this problem. I have registered a page on patreon.com for support this progect but was blocked same day for "suspected fraud" without any details.
It was very strange but I can’t do anything else there.

So, people, I need yours opinion about everething this. Any advises please. Tell me, if you think that the receivers are out of fashion now and there is no point in doing all this and spending money on it.

Re: Thetis has never been able to find odyssey2

Hello, Leo

Thank you for the QA job.Redownload please 2.1 pyw from GitHub and try again.

Thetis has never been able to find odyssey2

Leo Goto
 

Hi David,

Last time I posted to the mailing list was not him,
but I, Leo / WH2Q. I forgot to change the title.

1'st LED was blink, 2'nd LED was glow solid. LAN was communicating by
1Gbit.
But, Thetis has never been able to find odyssey2.

Now works with LAN Controller re-soldering and BL2.1 Firmware downloaded
from GitHub.
BootLoader_2.1.pyw, but "Change IP" did not work.
Because there is no choice, I could change it in BootLoader_2.0.pyw.

Thank you for help.

Re: assembling Ody 2 & Magic T

David Fainitski
 

Hello, Marc.
My congrats.

At first please redownload Bootloader 2.1 from my GitHub and change Bootloader.pof on the board with ByteBlaster programmer and Quartus.
Connect the board with PC by Ethernet and run it in bootloader mode - connect to KEY your headphones, temporary.
Look on the green test leds. First one should blink with 1 sec period, second one should glow solid if connection speed 1Gbit, blink slowly if connection 100Mbit and blink fast if no connection.
If you see that connection speed is 1Gbit, open ip V4 Network properties of this connection on PC and make sure that IP set as 192.168.2.100 and Mask set as 255.255.255.0 (by default).
Then use right Bootloader_2.1.pyw from that archive from Github.
After successfull test firstly write IP even if you want to use existing IP, only one time for new board.

After that you can dowload latest firmware ANP 1.20 from GitHub and upload rbf file to slot 1 with  Bootloader_2.1.pyw

Good luck

Hi David,

I made the Oddyssey2 unit 2(PCB v1.2), but Thetis does not recognize
Odyssey2. Odyssey 2 Unit 1(PCB v1.1) is working properly.

Thetis has never been able to find odyssey2.
It seems that there is a problem with the hardware?
Each power supply voltage and clock are operating normally. The LINK LED is also on.
It seems that there is no problem with the soldering of the LAN controller.
Check the point C2 is 0.93V

Odyssey_2_1.04_ANP and MCU_FW Odyssey2 not find.
Odyssey_2_1.06_ANP and MCU_FW Odyssey2 not find.
Odyssey_2_1.10_ANP and MCU_FW Odyssey2 not find.

Hello, Marc
I have uploaded gerber files to my GitHab repository. I hope it will helpfull.

Inner 4 x 4 pads connected to ground so shorting or breaking is not matter. the sculpel cut is not my job, likely it is PCB manufacturing job, known as "visual testing, for free for each order".

I don't know for what you need to use a stencil for FPGA soldering. For what ?  For applaying a soldering paste ? Please find one video on YouTube where stencil is using for BGA soldering, I wanna see this.

I have watched one of my boards very  curefully and found couple vias with no filling. I did not pay attention to it before. But it is not serious reason for soldering fail.  Probably you use bad flux which boils and bubbles. Try ChipQuick SMD291NL, this is the best. Or AMTECH VS-213-A-TF.

Re: assembling Ody 2 & Magic T

Hi
These questions particularly for David

- On the board I received,, the trace between a gpio and his via, located in the middle of the fpga, is cut (it looks like a scalpel cut) . Is it normal  (post-production patch) or is it an accident during the first assembly process or the shippping ?  

(the highlited trace in the attached picture it the one cut on the pcb) 





- As Layout 6 is a proprietary software and the demo version does not allow to export or print anything, could you please add to your github repository the full Gerber collection (with the solderpaste mask layer) ?

I failed trying to solder the fpga due to two reasons :
- the presence of already soldered peripheral components (it's absolutely impossible to use a bga stencil).
- the poor quality of the soldermask (many vias had no "tenting" on the BGA footprint, causing 2 shorts seen when x-raying the final result)

That's the reason why I would really appreciate using these Gerber and I think I won't be the only one :- ) 

Do not get me wrong, David. This is NOT a criticism of your work, you have proven for a long time the reliability of your projects since the first version of HiQSDR. These problem are just manufacturing gremlins

Ce que j’en pense 😊

 

In fact, I was speaking about the « Magic Tee » designed by David (in the Layout6 bunch of files located on his Github repo). I think he’s using approximately the same kind of transformer, but I would like to know the values of the input filter

(in other words the value of L1-L3 and C1-C3, and the nature of the « S » component). It’s pobably an LPF centered on 60 MHz

 

Totally agreed concerning all sorts of input bridges for measurement… I’m using a bunch of classical resistive couplers (Y and Delta) and some « old school » MCL coupler on my different analyzers (VNWA, N2PK, MSA).

 

Thanks Daniel and VY 73’

Marc. la voila:

The Magic-Tee



i like the last one best; sometimes called an 'inverting magic T' since
 the 2 outputs are 180 degrees out of phase.  we deployed them successfully
 at w5wmu multi op to share beverages between 80 and 160m stations.

plus, it only needs one core!
