moderated EXTIO File for HF+ ?

Guy Atkins
 

Hello, I've seen some discussion of a EXTIO DLL file for HF+ which one enthusiast has written, but evidently a working HF+ in-hand is still needed to finalize the file.

I know that all the early purchasers like myself are looking forward to using their receiver with their favorite programs. Mine are Studio 1, HDSDR, and occasionally the EXTIO version of SDRuno. Does AirSpy plan to release an "official" DLL and perhaps other supporting files specific to the HF+? I know that these things take time and manpower :^)

73,

Yes indeed, I was just being optimistic!

If we were working only on business days, you would be probably still waiting for the announcement next year ;-)

Do you really believe a cobra walkie talkie is a good source for stable carrier? The signal is *frequency* modulated in function of your ambient audio. ie. completely random. Plus even without modulation, these talkies have worse frequency accuracy and stability than the Airspies.
I suggest you send it to Joe at airspy.us for proper calibration.

Hi,


I see that in the release notes for r 11628 onward that "Set RTL max frequency to 14.4 MHz in direct sampling mode." has been added.

Is there any particular reason for this ?

I understand the desire use the tuner chip as much as possible in order to avoid Nyquist Alias signals and to have RF gain control. But I have an application where I wish to continue using direct sampling above 14.4MHz and this change has caused problems for me.

Could I suggest that it may be better if the user / admin could set this as required, as some configurations may need to use direct sampling above 14.4MHz and others may not.

It would be even better if it was possible to define frequency limits for direct / quadrature sampling in SDR Sharp and Spyserver, so that this could change automatically when the defined frequency boundary is crossed. This would save having to reconfigure things manually for example when you wish to move from HF to VHF and allow a mix of HF / VHF / UHF frequencies to be scanned.

It may also be possible to extend this proposed configuration option to automatically turn spyserver on-off (along with the frequency off-set) or turn the bias tee on / off (if folks are using this to switch antennas or pre-amps in / out).

Know your SDR. RTL's sample at 28.8MSPS, thus offering a first nyquist zone between 0 and 14.4MHz. Nope. This won't change.

DHL is definitely better (when you are not in France - they are awful). I had to fight to get my own prototypes delivered to me and not to unknown strangers.
In general DHL and TNT take 4 ~ 5 days to arrive anywhere in the world.

When I ordered the unit, I hurried because it said units are in stock and then somewhere else pre-order?!

I would also have ordered it when it would have said no stock but available soon – here is your possibility for a pre-order …

I find this a bit misleading but maybe the shopping software is not able to allow orders without showing valid stock?

 

Anyway I guess none of you has received any confirmation from itead.cc on the order as well, apart from the money transfer via paypal?

 

Now I will spend the time before this new RX gets here to have my antennas and preamps in shape to be able to use it to its full potential.

Thank you for your purchase. The shipping starts in the first week of December. I asked the distributors to put a note on their expected delivery dates.
And yes, you will need a good antenna. Not sure you will need the preamps tho.

ok then excuse my fault

so ... problem is on the sdrsharp side?

ok ... work for youssev

but why you need wfm?? tracking of sats is done in nfm and wfm is for
commercials only

if you need a wider nfm mode then crank up filters in sdrsharp ... or
what did i understood wrong??

dg9bfc sigi
=================================

Sigi,

As I reported, there is NO PROBLEM! SDR# is being set to exactly what the user requested.

During my own tests I used WFM with the appropriate bandwidth. Likely you'll even find the discussions in this group or GEO-Subscribers. There was a good reason at the time.

Cheers,
David

As Joe mentioned, yes the modern DTV pilot carriers are very accurate and widely available in the US. Here is a link that in great detail describes the pilot carrier frequencies used, including co-channel issues that at that time were of concern:   . http://earthsignals.com/add_CGC/RF_Column_77_Jul_98.pdf

Re: Airspy Mini calibrate #hardware

Airspy US
 

Are you aware that the ppm display is not showing the ppm error, but the delta of the oscillator to get to 0 ppm error? You don't want to get it as close to 0 as possible - you want it to be the correct factor for the unit which is virtually never "0".

Also, the accuracy of the Cobra HT is far worse than the accuracy of the Airspy units, so your HT likely threw the calibration off - perhaps by as much as 5 ppm.

You should only calibrate it to an accurate source. That means *no* HTs. In fact, no mobiles or bases either.

If the unit came from us, it was calibrated to a GPS clock before shipment and should not need recalibrated. Doing so would make it less accurate unless calibrated to a source of similar accuracy.

hmm as far as i know if you use wfm mode you have deemphasis added ... and for digital decodings (telemetry etc.) you need no filtering at all

thats why i was thinking nfm is the right mode

Your guess is incorrect.  WXtrack sends FM-W via the DDE interface, and it is correctly picked up by SDR#.  WXtrack can also send CW, LSB
