There are actually a fair number of us doing RA with the AirSpy.  That SDR is the center of our receiver at the Little Thompson Observatory
 in Berthoud, Colorado, USA (starkids.org).  I'd encourage you to have a look at our site.  We do both optical and radio astronomy.  We have
a system somewhat similar to yours, but have managed to capture and record raw I/Q data for an 8-MHz wide display utilizing a Russian "hack" to the
SDR# code.  Our STEM project for this past year was to determine the temperature of the hydrogen clouds surrounding the center of our galaxy, SAGA*.
Fortunately, we have a volunteer who is good at fitting Gaussian curves to a big 'bump' to separate out multiple Gaussian curves to an otherwise
unresolved big "bump" in the data.  We are using Radio SkyPipe to record the analog data directly (for show-and-tell during our puplic star nights)). 
Our feed is a full-wavelength loop spaced 1/4-wavelength in front of a splash plate built by our students.  Most of our hardware is from
MiniCircuits as we have another volunteer is has an "in" with them(professionally).  By the looks of your data, you're doing pretty good. 

If we can be of any assistance, please email us at the Observatory and or myself.  We'll be glad to share successes and failures.

I would recommend changing
bind_port = 5555-6666
to just a single number of your choice so that you know for certain what port will be used and can set up your router to forward that port inward to your Spyserver.
5555 is the normal value but as far as I know you can pick any number between 1024 and 65535.

No, sorry.  I was just using 192.168.xx.xx as an example of the types of number I've seen before.  They didn't appear in anything I was trying today.  spyserver.config came preset with  "bind_host = 0.0.0.0" .  I figured that was just a placeholder and not an actual address, but Prog said to use it.

On what do you base your statement of: "Most PCs will auto-configure so the crossover is not needed", I've never seen any literature to support.

Re: Beginner Questions: spyserver config

Experience. Of course, I still find the PCs I purchase nearly all have serial ports despite people telling me they have not been available for over 10 years on a PC (purchase quantity over the past 10 years is approaching 100 if not more). The only exceptions to this are a Surface tablet).

Have you tried it?

Nearly any device that requires an IP to be set has a default. I always set it by connecting a PC to it, set it as needed, then put that PC back on my network and connect the new device. That tactic has yet to fail.

When you connect two PCs direct to each other, one will act as a DHCP server and assign an IP to the other. I can't say the RPi does this, but I seem to recall that it will.

I do know of at least one bug on the RPi. For the VNC server, if you clone the SD card then change the RPI's IP, the VNC Server will still only respond to the original IP. Even the Real VNC people don't have an answer for that one.

Re: Beginner Questions: spyserver config

"Auto-sensing" LAN port is the term I've usually seen used for it. I could not recall it until you posted the info.

Maybe I just buy better PCs than most people. Unless the need specifies something different (like a Surface or iPad), I usually prefer Dell.

I have noticed some of my recent Micro PC purchases (over a dozen so far) do not all have Serial ports. They all do have the stamp in the case for them, though. Also, some have WiFi and some don't.

Hi Eddie,

thanks for the plugin! Works good for me with SDR# 1700, giving me a very convenient way to change mode and bandwith.
Acquired a NOS Shuttle Pro V2 at our last SWL camp for testing, was in mood to give it back, before I found your plugin.
The device was sold with setups for Winradio and PERSEUS years ago, but didn't work with the elad software for my FDM-Duo-r.

You're talking about settings of the network card. That does not change the hardware pins of the RJ-45 connector.  http://pinouts.ru/NetworkCables/ethernet_10_100_1000_pinout.shtml.  TD, at one end, has to connect to RD at the other end.

Sort of, the adapter will auto switch the pin directions (tx/rx) internally. So a straight through cable will work in an adapter-adapter scenario.

Re: Beginner Questions: spyserver config

Joe M.
 

Whether the change is made in hardware (crossover cable) or on the LAN port (software reconfiguration), the result is the same. Maybe Google the topic, as I don't care to tie up the list explaining it, and as I've said experience tells me it usually works fine. I have no doubt there are some cheap ports that will not auto-sense, but most I've tried do (and I think all in the last 20 or so years).

Yes, TD has to connect to RD, but when the TD/RD configuration is software defined, it doesn't matter if the cable is connected to the pins you think it must connect to. At one time in history, you would certainly be correct, but that hasn't been universally true for decades. Some smart engineer made a mint at fool-proofing the LAN port.

Remember - only one side has to auto-sense to match the other side, so both ports don't have to auto-sense.

No matter how many times you tell me what I've done will never work, I don't see my view changing. As I asked before, have you TRIED it?

Have you tried it?

Nearly any device that requires an IP to be set has a default. I always
set it by connecting a PC to it, set it as needed, then put that PC back
on my network and connect the new device. That tactic has yet to fail.

When you connect two PCs direct to each other, one will act as a DHCP
server and assign an IP to the other. I can't say the RPi does this, but
I seem to recall that it will.

I do know of at least one bug on the RPi. For the VNC server, if you
clone the SD card then change the RPI's IP, the VNC Server will still
only respond to the original IP. Even the Real VNC people don't have an
answer for that one.

But if the correct IP is not used, it will not matter if they are

Yes, it does. Connect to the IP of the RPi.

It will likely be a 192.168.x.x address. Port 5555.

You will enter that in the format 192.168.x.x:5555

Maybe it would make more sense to you, Tom, by thinking that
most LAN cards having a switchable Null Modem built in. :-)

Yes, TD has to connect to RD, but when the TD/RD configuration is
software defined, it doesn't matter if the cable is connected to the
pins you think it must connect to. At one time in history, you would
certainly be correct, but that hasn't been universally true for decades.
Some smart engineer made a mint at fool-proofing the LAN port.

Remember - only one side has to auto-sense to match the other side, so
both ports don't have to auto-sense.

No matter how many times you tell me what I've done will never work, I
don't see my view changing. As I asked before, have you TRIED it?

It is easy enough to scramble the pins on the network card or motherboard. Many systems feature this. You can also purchase cross-over cables. You are most likely to have success if you set fixed IP addresses at both ends of the cable. Something like 192.168.255.1 and 192.168.255.2 should work nicely and not conflict with any other addresses in your house.

Re: Beginner Questions: spyserver.config

Thanks Brian,

I wondered about this setting and tried changing it to 5555 as you suggest.  It didn't make any difference.  Same error message.

By the way.  Everybody seems to be assuming I have some kind of fancy network with routers and such and that I want to connect my Spyserver to the internet.  I do...someday, but not right now.  Right now my "system" consists only of my Pi running Spyserver, my Windows laptop and a 4 foot long ethernet cable.  That's it and that's what's giving me headaches.  This configuration couldn't be any simpler.

Thanks again Brian!  I do appreciate your help!

I would recommend changing

5555 is the normal value but as far as I know you can pick any number between 1024 and 65535.

No, sorry.  I was just using 192.168.xx.xx as an example of the types of number I've seen before.  They didn't appear in anything I was trying today.  spyserver.config came preset with  "bind_host = 0.0.0.0" .  I figured that was just a placeholder and not an actual address, but Prog said to use it.

Beginner Questions: Progress?

Ken Alexander
 

Someone suggested I try connecting to my Pi using its IP address...without actually saying how one determines the IP address.  In desperation, I typed "what is my IP address?" into my browser and I'll be damned...there it was.  A public IPv4 address and an internal address.

I tried the internal address ( a 192.168.xx.xx number) in spyserver.config and in SDR# and got an error message saying the server was busy.  No word on what it could be doing but at least it's a new error message and some sort of acknowledgement that my computer sees the Pi!

Now I wonder...does the Pi have its own IP address and Spyserver also have an IP address as well?  Did this just become even MORE confusing?

Recording longer files

Patrick
 

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
Pat

I did not mention anything about using a crossover cable because I know for a RPi they are not needed.
Raspberry pi 3 B+ uses a microchip LAN7515 chip
Raspberry pi 2 and 3 uses a microchip LAN9514 chip
Raspberry pi uses a microchip LAN9512 chip

All of which have "HP Auto-MDIX" support, so if a normal straight through cable is used when a crossover cable should have been used or a vica versa at the Ethernet physical layer it will swap the two receive pairs and the two receive pairs, if needed. So as long as one connected device supports " HP Auto-MDIX", the other one does not need to.
