VNC alternative

Jay Jackson <jjackson@...>
 

I use XRDP in place of Real VNC.  Then my Windows PC's can use the Windows Remote Desktop program. (XP, Windows 7,8+ &10)
I just purged realvnc-vnc-server.  Then installed tigervnc-standalone-server and xrdp.  It will setup the services and boot on startup.  Then reboot.
This may work for ISP's with restricted ports.  Since the Windows Remote Desktop (RDP) is commonly used, some ISP's may have the port (3389) open.

Prevent Windows from Turning Off USB Devices

WA8KHP -
 

To save power, Windows automatically shuts down the power to USB ports.  It surely saves power, but what if it is causing you problems with your auxiliary devices such as a Network connected RigPi or if you simply need a USB device that is always powered?

Power management is also a common cause of USB-connected device issues; if Windows is able to shut down your USB controller, it sometimes won’t be able to properly power it back up again, which will prevent some USB devices from working.

To prevent Windows from “managing” power to your USB controller or devices, follow these steps:

Thanks Howard,

You gave me a couple new ideas which I will look into.  I am a little old fashion and don't believe in annual subscriptions for software if I can find a solid work around!

Remote access using TeamViewer and Skype is OK but not as clean as your RigPi and Mumble audio solution.  I do like TeamViewer for the Panadapter and Waterfall if I am searching on the bands.

I am not aware of any USB Bridge cables from MFJ for USB A to USB A connection.

I do have the complete MFJ-1234 on order and hope to get it soon!

In 2012 when I got active again in Amateur Radio I purchased the IC-7600.  The Club that I belonged to then recommended using the SignaLink for digital communications.  Not knowing any better then I configured it that way and have used this method on the IC-7600.  The IC-7600 is my working backup rig as I purchased the ANAN-100D in late 2013.  This is my main rig so my PC is always on.

Of course FLEX owners who have an Android phone/tablet will find your RigPi solution a must have since FLEX has not taken any interesting in developing a relation with Android developers for a remote solution.   Maybe at Dayton they will announce a solution?

Re: RigPi to PC Network connection using USB cable

Howard Nurse, W6HN
 

David, thanks for the helpful description of how you are using RigPi.  Your use is actually upside down from how I normally think about using RigPi, which goes to show we will have many new ideas and suggestions as folks start to use RigPi.  Here are some additional thoughts.

 

You mentioned a TCP connection between a PC and RigPi for remote rig control.  Your description of how you are using RigPi is mainly for remote access to your PC.  Since you are running your PC while accessing your station from another place, there might be other ways to accomplish your goal aside from RigPi. 

 

While only available for iOS users, CommCat Mobile and the Windows QSXer program (both free) with a $15/year VoIP subscription would also work without RigPi.  CommCat provides a more robust solution and also has a free VP add-on that connects to PowerSDR, etc.  CommCat and CommCat Mobile will also connect to RigPi through a TCP connection. (CommCat, QSXer and CommCat Mobile are my programs.)

 

Another Windows program, TRX Manager, has remote capabilities and I believe uses a browser interface for mobile devices.

 

You can install a Murmur VoIP server, used for Mumble and Plumble clients, on Windows computers.

 

Your description of the physical connections between your PC and RigPi causes me to wonder if a ready-made PC-to-USB solution from MFJ might be a possible product.

 

You asked about the need to use RigPi Audio with your 7600.  Your message below is one answer…use Mumble on your Windows computer to interface audio with RigPi.  I’m not clear on why you aren’t already using the digital audio output from your radio rather than the SignaLink, but if it is free, you could connect the radio’s digital audio source to RigPi.  RigPi can use any USB audio source, bypassing the need for the RigPi Audio board.  MFJ sells the RigPi base (RPi 3+, case) without the accessory boards.  If you are only interested in SSB and have a radio that provides digital audio out, there is no need to purchase the Keyer and Audio boards other than for other switching capabilities provided through the Keyer/Audio PTT connections.

 

I hope I covered all bases, David!  Thanks again for your input here on the forum.

 

73, Howard W6HN

Subject: [RigPi] RigPi to PC Network connection using USB cable

 

Why did I want to connect the RigPi to a PC?  I needed CAT Control for my Apache-Labs SDR using PowerSDR software on the PC.  For Audio on the PC I used Mumble and on my Android phone/tablet I used Plumble to complete the RigPi connection.  This configuration also allowed me complete control of my digital software on the PC without changing anything.

Both the RigPi (Raspberry Pi computer) and a PC have USB A ports and cannot be directly connected without a special cable or cables.


The first thing you should be aware of is that there are several different kinds of USB-USB cables on the market. The one used to connect two PCs is called
“bridged” (or “USB networking cable”), because it has a small electronic circuit in the middle allowing the two PCs to talk to each other. There are A/A USB cables that, in spite of having two standard USB connectors at each end, don’t have a bridge chip and cannot be used to connect two PCs. In fact, if you use an A/A USB cable, you can burn the USB ports of your computers or even their power supplies. So, these A/A USB cables are completely useless. A/B USB cables are used to connect your computer to peripherals such as printers and scanners, so they also won’t meet your needs.


So how did I solve this network problem?  I used two, USB to Serial Port cables the have the FTDI chip set and connected these two cables together with a NULL Modem cable.  Beaware there are USB BRIDGE cables that do not ust FTDI chip sets and may cause problems.  This configuration became my BRIDGE CONNECTION.



I used two FTDI Serial TTL-232 USB Cable that cost $18 from Adafruit:

I connected the two cables together using a Null Modem cable that cost $6:

Re: IC-7600 -- SignaLink -- RigPI

WA8KHP -
 

Mark,

Thanks but again you missed the point.

My IC-7600 is interfaced to a SignaLink for AUDIO then the USB B port on the SignaLink goes to a USB A port on the PC giving me a digital audio connection.  The IC-7600 CAT Control uses the USB port B and is directly connected to a USB port A on my PC.

This is digital mode communication that many Hams already have already working with Cat and Audio connections from their rigs to a PC.  Some of them may not need the SignaLink for audio as the newer rigs have this function internally.

The new potential RigPi users just want to add SSB communication for remote operation using RigPi.


I do not want to connect the IC-7600 directly to the RigPi as you reference in your link that breakes my digital software connection to my PC.

Remember this is NOT EITHER OR but BOTH digital for local use and SSB for remote use without changing cables or rig configurations.

RigPi must do a NETWORK connection to the PC for CAT Control and then use Mumble on the PC for Audio.  There are two problems with this connection to my IC-7600.  The audio level is set for data levels NOT microphone/speaker inputs/outputs on the IC-7600 and I am not aware of a way to combine or bridge two USB ports for CAT Control on the PC.

Re: IC-7600 -- SignaLink -- RigPI

Mark Weisheimer
 

I actually did reference the CAT control when I said to connect both of the USB cables to the RigPi.
One is the USB cable between the RigPi and the SignaLink.
The second is the USB cable from the RigPi to the IC-7600 USB port.
That second cable is for CAT in this instance.
Since this is Linux on the RigPi, you don't need a virtual port combiner.
Folks use RPi's and SignaLink already, such as here:

https://groups.io/g/linuxham/topic/howto_interface_signalink_and/5794424?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,5794424

Or, for those that don't have a SignaLink, the IC-7600 can be used with the RigPi directly, but for this discussion, that runs afoul of Mike's current rig settings.

Well we'll see what Howard sez.

.I got the impression digital modes were intended for local ops but ya
still got the issue of splitting CAT and Audio between the digital
software and RSS.

You both missed the target by a mile!

There are two sub parts to the problem, CAT Control and Audio. Both of you ONLY talked about Audio.

The main problem is "How can I use RigPi with my current cable connection to my IC-7600?" Many Hams already have already have Cat and Audio connections working for digital modes.

I do NOT want to give up my digital modes that currently work on the IC-7600. I just want to add RigPi remote SSB VOICE operation, NO cable changes or changing settings in my IC-7600. My current hardware using the SignaLink and the data settings in the IC-7600 are perfect!

I do NOT believe it is possible for NON SDR rigs to do both digital data and SSB RigPi communications without changing cable connections and hardware settings in the radio. A SDR rig can do it. I am defining an SDR rig as having PC software such as PowerSDR, SmartSDR etc (Apache-Labs, Flex, etc.) and use VAC, VSP or DAX. RigPi needs to connect to the PC via TCP or USB to Serial cables plus a Null Modem cable like I have done for my Apache-Labs 100D.

I believe Howard is going to need a Disclaimer on what kind of connections RigPi can do.

Re: IC-7600 -- SignaLink -- RigPI

David, I looked at the IC-7600 manual and it looks like it has an
internal soundcard.

I recently found this document that might help
http://www.dxlabsuite.com/dxlabwiki/ConnectingIcom72007600

Here's an excerpt from that document that discusses the 7600:

"to configure your IC-7600 to accept audio from the USB interface,
decide whether your digital mode operation will employ DATA 1 mode
(D1), DATA 2 mode (D2), DATA 3 mode (D3), or will be accomplished with
DATA mode not in use. Then open the transceiver's ACC SET menu and

set the appropriate entry's signal source to USB, as shown on page 124
of the IC-7600 Instruction Manual

set the USB MOD level to 50% (you can increase or decrease this later
to adjust the audio drive level)"

If you hurry you can try it before ya goto Dayton!

I am using a Virtual Serial Port (VSP) program that allows me to take the Cat Control Port from the IC-7600 and the digital audio port from the SignaLink and SPLIT each port which allows multiple software programs on the PC to use them at the same time.

I am not aware of a PORT COMBINER function in the software that I currently have.

1. How can I use RigPi with my current cable connection?
2. Can I still use my current cable connections or must I start over with RigPi?
3. Must I use the Audio In/Out on the MFJ-1234 RigPi for my audio to/from the IC-7600? How would I connect the RigPi audio to the PC to use my existing digital software?

Another tough question for you which I hope you have an answer for!

Re: IC-7600 -- SignaLink -- RigPI

I have successfully interfaced the Elad FDM-DUO to RigPi. The FDM-DUO
uses two USB connections, one for CAT, the other for the internal
soundcard audio. RigPi handles it fine. CPU utilization is about
50-60 and the cpu runs too warm to touch for long but a heat sink
helped and when I changed the rpi over to a M2 SSD, CPU util is half
what it was using mSD. Should work with SignalLink if the sound chip
is supported. I'd try it if I could find my SignalLink! Give it a
try... shud b easier than what you've done so far. Mike, WB8CXO

Re: RigPi Firmware SD Card back ordered on MFJ

Glad to hear that...placed an order, didn't get the delayed email, and was wondering what was going on..

Just got a 7300, and been trying to do a Pi interface myself, but not seeing the whole picture yet.

BTW...I'm doing documentation for several other projects, but who do I shoot documentation boo-boos to? Spotted one, and I can keep my eye out for more..

(I know...for 3 versions of a double-sided trifold, I had the exact same sentence in two different paragraphs, and no one spotted it!)

I await my delivery with baited breathe!


Re: RigPi Firmware SD Card back ordered on MFJ

Howard Nurse, W6HN
 

Hi Marc, and welcome!

Once the dust settles a bit I will begin to have time to activate the GitHub repository.  Note that RigPi is open source except for the tool used to create the graphic components on the main Tuner window.  One of the first tasks is to create open source replacements for the frequency panel, s-meter and tuning knob.

The GitHub repository will only include the RigPi software, so you will need to install a LAMP stack on your Raspberry Pi to get going.  There are plenty of sites you can find by googling that help with that process.

I’m looking forward to having additional folks involved as we move forward!

MFJ is finishing up the first production run now, so shipments will begin soon!

RigPi Firmware SD Card back ordered on MFJ

Marc
 

I ordered the RigPi SD card, 'RIGPI OS FIRMWARE FOR MFJ-1234' part#  MFJ-1234SD from MFJ a week ago and just today got an email saying it was back ordered with no indication of when it would be fulfilled.
While I am waiting is there a way to download a sd card image (even a beta version) so I can make an sd card and get started learning how it might work for my station?
I notice on the RigPi web site there is a reference to an open source download, but the link seems to go to the github home page only.
Thanks.

Thanks Howard. I guess my apprehensions are premature having had issues with other so-called compatible devices recently. Thanks for confirming. I'm sure I'll have many more questions...just a warning...LOL I appreciate your response!


Using Netgear routers with RigPi

Howard Nurse, W6HN
 

Newer Netgear routers have two features that really come in handy. 

You can set up a free dynamic dns account which your router updates with any IP changes on the Internet side.  This is much more economical than dyndns.com which charges $55/year. With this service, you can connect using <your call>.mynetgear.com rather that by using the Internet IP currently assigned to your connection (which can change).  

Netgear routers also provide what they call Remote Management, allowing you to log in while away from home to change port forwarding if necessary.  This is handy if you haven't set up a static IP on RigPi and it reboots for some reason and is assigned a new IP.

You might be wondering what port forwarding is.  For security reasons, routers are set up to shield you local network from incoming connections from the outside world.  After all, you don't want just anyone to intrude on your system!  Port forwarding provides a bridge through your router for one or a range of ports.  You can connect to RigPi from a remote location using port forwarding.  Be sure to enable password protection on your RigPi before allowing access to the outside world!  There is more info about port forwarding in RigPPi Help.

Other router brands may provide the same or equivalent services.

(Disclaimer: I don't have any connection with Netgear!)

73, Howard W6HN


Re: Does Rigpi require port forwarding

Kurt Lautenschlager
 

You may also see if your router has a DMZ, this will allow you to add the IP of the RigPi.  Sort of does the same thing as port forward by allow 1 device access to all ports.

I use this currently setting on my RemoteRig setup with no problems.
