Hi,

 

You need 3.0.4 which will be available in a week.

 

It’s a shame you don’t sell the Odyssey .

Hello, Simon.

The one of firmwares avalaible for ody-2 uses openHPSDR New Protocol, so this transceiver works with your Console V3.
I tried this just  yesterday and tomorrow with my new toy - Dell Venue 11 Pro.



It vorks very good, but when I switch to internal Odyssey speaker, the sound is interrupted. The programm shows Audio delay 0ms. I think need increase buffer size to 5 ms at least. Is this possible ?

At this time I don't assembly Odyssey more because I switched to other project. I can offer only semy-assembled boards for DIY  http://www.sdr-deluxe.com/shop/30/desc/chastichno-sobrannaja-plata-transivera-odissej-2

Dell Venue 11 Pro with my Odyssey-2

David Fainitski
 

Hi, people.

Did you see on eBay there are many offers with this small Windows ultrabook ? Dell Venue 11 Pro ?

I bouth one, model 7140 with an incredible powerfull processor m-5Y71 !!!  Only $150, in great condition. 

It has not LAN connection but I have used USB3.0 to LAN Gigabit  Adapter and connected my Odyssey without any problems.

I Installed PowerSDR MRX, Thetis and SDR-Console V3 for testing of CPU load.

Here is result in the same conditions:

PowerSDR:
48 кГц - 12%
96 кГц - 15%
192 кГц - 20%
384 кГц - 25%
1152 кГц - 33%

Thetis:
48 кГц - 22%
96 кГц - 27%
192 кГц - 28%
384 кГц - 32%
1536 кГц - 60%

SDR-Console V3:
48 кГц - 16%
96 кГц - 16%
192 кГц - 16%
384 кГц - 18%
1536 кГц - 20%

I lounched SDR-Console V3 again this morning ang CPU loading was only 10% with 192 kHz. Don't know why.

A few fotos. You can see my Ody-2 in the new double-size housing together with 50W HFPU boards.

Hi All,

 

In order to provide full support for this excellent transceiver I need a working unit. When boards / kits are available I will buy one. You can’t beat having the hardware to be able to provide good support.

No, I will not to do preorders more. I need a time for programming and other projects.

Hello, Dan
This is the simple solution that using now in IC7300, FT891 and other modern transceivers.

Re: Bias temperature compensation?

David Fainitski
 

Hello, Steve.
As you can see MOSFET transistor were used in this design so don't need to use a temperature compensation. 
The most of factory transceivers don't have that.
Also, I don't know what is connection between T.compensation and IMD problem. I know that without its there is problem of overheat simple BJT transistors.

Best regards, David

The Odyssey-2 and 50W PA go on DX-pedition to Madagascar !

David Fainitski
 

Alex K2BB and his friend Paul UU0JR will be active as 5R8R from Nosy Be Island (IOTA AF-057), Madagascar during November 19-29, 2018

They are planning to have typical 160-10m CW/SSB/Digi dx-pedition activity and participate in CQ WW CW contest in multi-single category, maybe multi-two if we have enough operators...

They will have 2 stations... 
Radios, so far: Kenwood TS-590, Icom IC-7300, Elecraft KX3 just in case, Odyssey 2 SDR for fun, one radio will have Elecraft KPA-500 amplifier, second station will be 100W 
Antennas, so far: 2 verticals covering 160-80-40-30m, a Spiderbeam for 20...10m and possibly a Beverage if we have enough space for it.

He also invites other radio amateurs to join in this trip.

Hi.
I will try to assemble a couple pieces.
Now I drow schematic, it is important.

I want also to sell this amp that I have now and will try assembly another in doublesize case. I hope install the Odyssey and amp in one case together.

So if somebody want to buy this amp write me a message.

Hi people.
Finally, I can introduce you to an amplifier as a complete design.

I will draw a schematic and prepare a BOM in near future.
