Re: Recording longer files

Patrick
 

I should indeed give Linrad a try but I find it quite difficult to master ! (I watched many of your clips showing Linrad in action).
So it seems it is not possible to record larger files running SDR# ...  What a pity.

Download the ExtIO file from http://www.montefusco.com/airspyhf/ Copy it into the HDSDR folder. That’s it.

AirSpy HF+ - help needed

Gary Moles <morgannz@...>
 

Hi, Looking for help (advice) for getting AirSpy HF+ to run with HDSDR.

I can run the KC9QLE SDR on HDSDR and the Airspy runs perfectly on SDR# (as does the KC9QLE SDR).

But HDSDR just won't recognise AirSpy.

All relevant advice gratefully received. Footnote - all on the same computer.

Regards

There are several standard extensions to the .wav format which allow essentially unlimited recording. Why not use one or more of them?

Hi there,

A single recorded file (full 768 kHz BW) seems to be limited to 2 Go ; this
means the recording won't last more than about 12 minutes.

Is it possible to record a single file during 30 minutes or 1h or even more
? (still at 768 kHz BW of course).

Thanks

You problem is that you can not currently connect to your RPi through the directly connected cable because neither end has been configured with an IP address.

You have a physical cable connected, but there is no configuration telling the device how to use the cable.
You will get far better support for a RPi, if you really want to configure your device in this unusual way, by plugging something like "site:raspberrypi.org how do I setup with a direct cable connection" into your search engine of choice, or "connect raspberry pi to PC without router" or by posting a query on the raspberry pi support forums. https://www.raspberrypi.org/forums/
Or you could just set things up in a much easier way, you have three options as I see it:
RPi<-ethernet cable->internet router<-ethernet cable->Windows PC (this would be the default configuration for most people, you plug the cables in and everything just works)
RPi<-wifi->internet router<-ethernet cable->Windows PC (a tiny bit harder than the above but there is a idiot proof guide on https://www.raspberrypi.org/help/ )
RPi<-ethernet cable->Windows PC (you will spend a very long time trying to get this configuration to work as a beginner)

He can connect. He says ping works, although he has not said what addresses they have respectively to be sure.

RPi: ifconfig >spoo1.txt
PC: ipconfig >spoo2.txt

Grab both spoo1.txt and spoo2.txt and post them - unless, of course, he has it working now. If all that matches and ping works then make the ports agree. If they agree and no comms then play with the PC firewall.

Hello Patrick,

you can use Linrad with your Airspy and record unlimited
file sizes. (Your hard disk would be the limit.)

You can locate regions of interest and write small files
that can be converted to standard .wav files if you want
to process on another SDR software.

Linrad uses a 64 bit file pointer while standard for .wav
files is a 32 bit pointer.

Hi there,

A single recorded file (full 768 kHz BW) seems to be limited to 2 Go ; this
means the recording won't last more than about 12 minutes.

Is it possible to record a single file during 30 minutes or 1h or even more
? (still at 768 kHz BW of course).

Thanks

Re: USB cable quality and QRM in a spyserver setup with an Airspy Hf+ and Raspberry PI3. 6 microUSB cable test. #airspyhfplus #bestpractice #raspberrypi

zennix2014@...
 

Can you guys elaborate on the power supply wiring, and also the cable changes? 

I'm heading down the same path (airspy HF+, and raspberrypi), and have had noise issues in the past with other SDRs picking up noise, so more details on connection, power supply make/model, schematics / wiring diagrams, etc., would be very helpful.

I'm unclear about the "self-building" cable part - if you split the USB cable apart or what, so any details help.

I would love to see the Astrospy program have a feature to periodically log data to a file with a a timestamp.  It would be such an obvious feature to add.

Wifi?  No.  My Pi and Windows laptop are connected by an ethernet cable.  No routers, just a short cable.

Pretty sure I've tried that address several times before but I'll try it again.

Speaking of SDR.... "Reference" for ES-Hail is Lime SDR.
Mini's price is 159$ and its RX Performance is not Great.

I think 200$ could be a beginning for a SDR with a decent RX quality and TX possibilities.

My wish list:

TX possibilities
RX and TX: 50Mhz to 3.5 Ghz.
External Clock reference input.
Good RX characteristics like HF+ and R2.

Tnx !
I was thinking a small USB wide band ODFM transceiver would be nice nowadays.
This is not an SDR, but it could be used to transmit cam data stream or run a small TCP/IP network, or even create a bi-directional data link for drones.
Of course, it could work flawlessly for Es'hail2 with a suitable LNB.

The default coverage can be from 50 MHz to 1300 MHz, but could also be designed to go up to 5.8 GHz.

Anyone interested?
How much would you pay for it?

You want the 192.168.2.34 address, so 192.168.2.34:5555 is what you use.

Is your PC 192.168.2.x also? (it needs to be within the same subnet)
