SDR (Software Defined Radio) Transceiver

[bobltx]

I am trying to set up band pass filter switching using I2C by compiling DC2PD's file and am assuming that all the "include" files are there for this.

I'm not sure if I understand this part. Normally, the I2C code is included in the SDR application available from the Red Pitaya application marketplace.

Hi Pavel,

The version I have is - 'ecosystem-0.95-1-6deb253-sdr-transceiver-hpsdr' from your "SDR transceiver compatible with HPSDR" pages, but I have no signals on the I2C or SPI pins so that must be the wrong one.
I just logged in to the Red Pitaya site, found the "Application Market Place" found the sdr application 0.94-1191, but could see no way to download it.

Maybe I'm just getting too old for all this.

Regards
Bob

It explains why you don't have gcc. It's only available if you install the SD card images from http://redpitaya.com/quick-start or from http://pavel-demin.github.io/red-pitaya ... -ecosystem

The 'ecosystem-0.95-1-6deb253-sdr-transceiver-hpsdr' image should be OK if you don't need to recompile the code.

but I have no signals on the I2C or SPI pins so that must be the wrong one.

I'm not sure if Quisk can control the filters via the I2C and SPI pins. Have you tried PowerSDR mRX PS?

Hi Pavel,
I think you may have found the reason I have no control signals. The 'quisk_config' file is for the Hermes-Lite and has a section referring to 'Hermes_BandDict = ' followed by a list of the bands, I thought this was the source of the necessary signals. Obviously not, so I will see if Jim
Ahlstrom can incorporate the function into Quisk. Either that or will need to learn Python and write my own file.

Using PowerSDR mRX means giving in and using Windows I do everything else with Linux so I will see if I can get this project to run
on it as well, after all the Red Pitaya is Linux based.

Many thanks for your help, I am sorry to have taken up so much of your valuable time, I will let you know how I get on.

Best Regards

Hello,
with Pavel's assistance I'm working on the "DiscoRedTRX", a standalone version for a RedPitaya TRX. Please have a look at
http://www.eham.net/ehamforum/smf/index ... c=110293.0

Who wants to participate in the development process? He (or she) is very welcome.

Best regards, Wolfgang (DH1AKF)

Hello!
Yesterday became owner Red Pitaya, has installed mRX 3.3.9, all works well, but is not present CW manipulation, input PTT works, and input DOT DASH are silent. That can be, help to understand a problem.

I think how to solve problem MDS RP. That will turn out I will inform.

On video adjustment power. It is very necessary, that cursor Drive too worked 10-12dB, with SNR TX all will be good.

Pavel,

Long time no post here, so forgive me...I've been creating a new add-on board for the Red Pitaya that amplifies the receive (by 22dB) and the transmit (up to 35dB from 10mW) and have provisions for the PTT keying that works great..! I seem to remember that at the time of the first creation of that functionality nearly a year ago, that the DOT and DASH capability worked, too, and I had asked that a 'cw-keyer' algorithm be added to the Red Pitaya image. Again, I know at the time that all that functionality (especially the PTT) was working great, but it seems that the newer images of the RP code do not have the DOT and DASH features, but still have PTT (still works great). Is there going to be CW DASH/DOT capability plumbed-in soon? Again, I have provisions for it on my board design and I'd like to think users will be able to use that functionality at some time.

Let me know your thoughts on that, Pavel - hope to hear back from you soon..!

It seems SDR-Radio V3 supports OpenHPSDR Ethernet Protocol written by Phil Harman VK6PH.
Will also Redpitaya in the future be usable with SDR-Radio software?
