Hi Sven
You can find the releases:
To help you i need more infomation about your setting; look into the wiki for what you can check.
Inforrmation about configuration and performance can be found at:
You want more receivers i assume for skimming:
The radioberry started to combine the radioberry hat and a rpi (started with rpi-2) to make a standalone radio running pihpsdr.
Iam using a magnetic loop; so the need for large bandwith is low....
The sdr program pihpsdr (by John Melton) was modified to support the radioberry protocol.... but people like to use also different SDR programs; and not only running at the rpi.
So i decided to move to supporting the protocol-1 used by the openHPSDR group; enabling the use of different SDR programs but also use the radio remote using the ethernet protocol.
This again triggers the need for more receivers which are supported by a lot of these SDR programs.
More receiveres and higher sample rates .... using a general purpose computer like the RPI and getting the IQ data from the GPIO is a challenge...
so there are limits in these data streams (see wiki for detailed explanation).
For skimming in large bandwidths and multiple channels the radioberry attached to a rpi is not suitable.
What i have done is making multiple receivers/channels possilble using a small bandwith (reduced data stream) by using a specific 4K sampling rate gateware
This solution gives you 8 channels for ft8 decoding :
For increasing sample rate iam currently developing a juice board:
This board (in development state) now supports 6 RX channels and a TX channel... dropping the tx channel i think an additonal RX channel will be possible.
Hope this helps
