So as long as one connected device supports " HP Auto-MDIX", the other one does not need to.

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

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?

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! Ken Alexander

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
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? Joe M.

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. -Micah

Re: Contour Shuttle Pro V2 plugin for SDR#

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. vy73 chris Christof Proft - Radiofreunde NRW https://www.facebook.com/radiofreundenrw/

"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.

Re: Beginner Questions: spyserver.config
Brian Gregory <bdgregory@...>
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.
