What is the current market of non-dongle SDR receivers? I am talking about stand alone SDR receivers that do not need a PC to operate them (like the upcoming Icom IC-R8600.) I have been having trouble determining everything that is currently out there. Thanks for your help.
This is not an answer to your question, just a clarification.
Just to be clear, "dongle" SDRs generally refer to a specific set of SDRs, things like the R820/R820T2, Funcube Dongle, etc. These are many peoples entry into the SDR world. However not all SDRs are "dongles". The majority of models (not numbers) of SDR are not Dongles. Things like the Peresus SDR, NetSDR, SDR-IQ, etc. But these other SDRs all still require a computer.
Many radios are stand alone SDRs today, no external computer required, however the majority of these are transceivers (like the KX2 and 3, IC7300, FTdx-5000, etc), not just receivers. There have been a few prototype stand alone SDR receivers shown around, however they have typically been DIY things or commercial projects that have not gotten off the ground yet.
On the DIY side of things, there are a few guides out there to doing a stand alone SDR based on RaspBerry Pi and an SDR. as well as a couple based on less common boards.
On the production side of things, the already mentioned CR-1A, AR-DV1, and the upcoming R8600 seem to be the only things out there either in numbers or with good prospects of sales. Items like the StampPFL just never see to go places.
While SDR has been around for a while now we are still pretty early on the cycle of it. I expect over the next 5 years you will see more and more stand alone SDR receivers on the market, however at the same time the market for receivers might be dwindling, so it could be a slow pull.
T!
