New Red Pitaya price and suitability
Posted: Thu Feb 21, 2019 12:14 pm
I have happily used my old Red Pitaya for some years now, but I just had notification from you that the New Red Pitaya aimed at the SDR community is €499 at a discounted price! I think the manufacturers should be careful with this very high price. There are already transceiver SDRs which cover a much greater frequency range than RP using custom RF chips.
An example is the LimeSDR mini for $159. They have just introduced the LimeNET Micro which has a built in Raspberry Pi compute module for $299. With a frequency range from 100kHz to 3.8GHz, the Micro can run stand-alone just like the RP. I love the RP, and some very clever code has been written for this very flexible unit - especially the WSPR standalone Tx/Rx, but it is getting left behind with these latest units.
I am just about to use my LimeSDR mini for uplink to the Es'Hail2 satellite on 2.4GHz. In order to do that with the RP, I would need to build an up-converter. I am receiving the 10.5GHz signal from Es'Hail with an LNB and AirSpy SDR or the same LimeSDR at 750MHz - again - would need a down-converter with the RP.
