V/U/SHF and QO-100 SDR Transceiver Project

Hi All,

After many years we had time have some progress on our SDR Transceiver project mainly for use in QO-100 as a portable setup.

The device idea was very old with using some up/down converters in first prototypes.

When Guido release usdx, it changed the way of the project and also with Arjante's and Klaus's additions for raspberry pi pico and other our ideas evaolved to use this new PICO SDR architecture for our QO-100 SR Portable setup.

The group (OH2UDS Baris, OH2CAV Burcu, WB2CBA Barbaros and TA7MVL Mevlut) started the new design concept last month and now we have the prototypes.

The basic idea is to have a 10x10x10 (1U cubesat frame) transceiver which will have the following features:

- Full duplex operation (separate TX and RX boards)

- CW/AM/SBB modulation (maybe direct digital modes in future)

- PA included (at least a few watts)

- TFT color Display

- Waterfall and spectrum of at least ~100Khz BW

- Battery operated

- All in one box that can be mounted to a portable dish

- and so many features in mind

Here I will put some initial prototype photos and inform you all for the progress whenever we have some time to work on project

Anyone who would like to contribute to HW and/or FW is welcome...

Here is a video (sorry, descriptions are in Turkish) showing our progress for the last few weeks.. Including a real over satellite test at the end....

I would like to thank all who inspired and supported us.....

Some hardware development news

English (as much as I can)

Prototype-2 will be available when I get back home (we are still in out EU/TA QO-100 Rover Tour)

in ATOLYE Team we decided to do some fixes and changes to the current design. Also I will have time for FW development when.I am back (not possible while driving 7-8 hours daily

I will inform you here when news come out....
