The Rafael Micro R820T2 chip has been discontinued since march 2018. It will need a replacement.

I think we noted in that post that the R820T2 is discontinued, but production will continue as normal. Basically, since the demand for these chips is still high we can still get them produced in custom bulk orders. They're just not continually producing them anymore, and not selling them to distributors.

Whats the prospective timeline on a V2?
Still a long time away, the soonest possible would be mid-2020. Realistically, probably quarter 3/4 2020.

Some comments on the wish list:

1) Definitely RF switches to enable calibration without disconnecting antennas. This would pave the way for fixed site rooftop installations, and potentially a crowdsourced RDF network. Think about these mounted on towers or rooftops, and taskable from a frequency POV! Automatic calibration would also be super useful in this context and remove a ton of complexity and friction.

2) Definitely agree for an USB-C based designed using PD, and also USB-C to talk to the compute device, preferably on 2 connectors. USB-C has come a long way in the last 2 years, especially for power distribution.

3) I agree with others, don't bundle in compute - the compute changes faster than the radios should. But it would be nice if the software were more generic in terms of platform so higher performance ZCZPU's could be used. I love my odroid N2 for these sorts of uses, and a lot faster than an RPI4.

4) A recommended set of antennas for elevated fixed installation, probably vertical dipoles.

thankls,
