Re: Airspy Mini calibrate
#hardware
From the lower edge of the channel the standard ATSC pilot is at 309.440559 kHz.
So, if the lower edge of the channel is 500 MHz, the pilot would be at 500.309440559 MHz, and no you cannot tune with

What is the point of using the 'Aux VFO' plugin for that specific purpose ???

Re: Airspy Mini calibrate

There is a suggestion on the web that the pilot carriers for US DTV are worth using. I tuned one earlier to day on a GPS stabilized AirSpy R1 and figure they are good for 1ppm level, at least. I am

The guts of the dongles don't really allow tuning higher than 14.4 MHz. For that matter 14.4 MHz may be rather pushing the RTL chip, the one which performs IF filtering and A/D conversion.

Re: Shipping dates - any updates/confirmations?
#airspyhfplus
I think Joerg meant confirmation of shipping, I too received the confirmation of the order, that would be standard procedure when parting with pocket money.

Re: EXTIO File for HF+ ?
We implemented our own equivalent of "synchronous AM" with a "Lock Carrier" feature that can be combined with any other mode. It is much less prone to lose lock in weak signals and can be combined

Re: EXTIO File for HF+ ?
Great! Thanks for the information. Is Andrea's EXTIO available in the final, DLL format? I'm not a software geek to know for sure, but it looks to me like his web site only links to the source data

Hi,
Unfortunately, although I'm also keen on technical correctness, it can stifle experimentation, innovation and perhaps even joy :-)

The Odroid XU4 has a slight edge on this use case.

Well. Make it great then! Learn how to use the plethora of plugins available to you - starting from the Aux VFO.
But of course, as long as you are unable to see DSP flaws in software, your perception

I simply wish the combo SDR# HF+ is so great that I won't need other soft for these purposes.

If you don't mind aliases (ie. signals that aren't there) you can use whatever software you wish.

I am running the Asus Tinker board…one with an Airspy and one with a RTLSDR V3
It handles the 2.5 MHZ Airspy bandwidth and the 2.4 RTLSDR fine. And I think 10 users would be fine.

Nope. Correctness first. We don't have an s-meter for the same reason. We have an SNR-Meter.
