Alan,

Are you planning any support for the new (if temporary) RTL-SDR.COM V4 dongle?

Thanks,
David GM8ARV

Hi David,
I've not read up on this, so what is different? It may just work with the current support.

Alan,

Several differences - it has a built-in HF up-converter covering 500 kHz
upwards, so the API changes. Direct sampling is no longer required.
Additional filter options are available with the new R828D receiver chip.

They offer a new DLL so perhaps that's enough for SharpSDR (when renamed).
Both SDR# and SDR-Console now provide an updated DLL as part of their installation.

I have one and it works, but only down to ~500 kHz. 198 kHz is audible, but at
reduced strength.

There is one issue that might influence a support decision - the device is
built with a different receiver chip, of which there is about a year's worth of
stock. It's cheaper, though. Perhaps indicative of their ideas for the V.5
dongle?

Hi,
thanks for the links, I shall look into it. At first sight the basics should work by just copying the new driver in and renaming it.
