From the main N1MM window (GUI), left click on Config and choose Configure Ports, Telnet Address, Other.

Configure the Audio and PTT ports in N1MMįirst, we will set up the CAT port for N1MM. PTT does not need to be configured since we’re using CAT commands to trigger PTT from N1MM.Check on the Apply button and close the Setup form.In the CAT Control section, click on the drop down box and select the virtual com port of the virtual com port pair defied previously in a step above.PowerSDR will use the virtual com port 13 of the virtual comport pair 3/13. For the N1MM configuration, we will use a more optimized configuration but it will work with the conservative configuration.Ĭonfigure PowerSDR to use a com port for CAT control by configuring. The instructions in the KC article represent a very 'conservative' configuration.

Using the Knowledge Center article, How to Setup Virtual Audio Cable ( VAC) 4.0x with PowerSDR 1.x, execute steps 1 through 3 for the instructions to configure the two (2) VAC audio cables. If you have already installed previous version of VAC 4.x, don't forget to uninstall it before installation. If you are installing VAC for the first time, please review the readme.txt and vac.chm (Windows Help) files before installation. Simply unpack it into an empty folder, run setup.exe application and follow the instructions displayed.

The VAC package is distributed as a ZIP archive. This procedure has not been tested with the 3.x version of VAC and some older versions of VAC 4.x have been reported not to work for whatever reason.

To get them, you must contact the company or software distributor from whom you purchased VAC from initially as the upgrades are not directly available from the VAC home page. If you have VAC 4.x, but it is not version 4.09, you are entitled to get minor version upgrades. Using the URL listed above in Step 3 of the Configuration Overview and Required Software section for the VAC home page you can purchase your copy of VAC if you have not already done so.

#FLEXRADIO VOICE KEYER RUMLOGNG INSTALL#

Download, install and configure the Virtual Audio Cable software ( VAC)Īs noted above, you must purchase VAC as it is a commercial product. Note this screenshot shows a set up for using DDUtil but for the purpose of this example we’ll use port 3/13 and assume DDUtil is not in use. This is a screen shot of VSP Manager Settings. If you are unfamiliar with the concept of virtual com port pairs that are sometimes called virtual null modem cables, you can refer to the Knowledge Center article, What is a virtual com port or null modem emulator?, for a detailed description of how virtual com port software works. Download, install and configure a virtual com port software such as VSP Manager for CAT Control Using the URL listed above in Step 1 of the Configuration Overview and Required Software section for the N1MM home page download and install N1MM. This allows PowerSDR to seamlessly interface with N1MM. N1MM has recently been improved to allow separate sound devices (cards) for input and output. This is probably the most confusing part of the N1MM configuration. The final step is to configure the audio input and output connections for N1MM. The benefit of VAC is that the audio exchanged between PowerSDR and N1MM stays entirely in the digital domain resulting in high dynamic range signals and there are no wires to introduce RF into the software defined radio system. VAC makes PowerSDR 'look' like a sound card or Windows audio device to N1MM. VAC is a program that transfers the RX/ TX audio from PowerSDR to N1MM and subsequently transfers the TX audio from N1MM to PowerSDR without using a physical interface between the radio and a computer sound card.

Download, install and configure the Virtual Audio Cable software ( VAC) For this procedure, N1MM 11.7.0 was used. You can download N1MM software from the N1MM Home Page. Download and install the latest version of N1MM It should work equally well on any Flex radio.

#FLEXRADIO VOICE KEYER RUMLOGNG DRIVER#

This procedure was developed using the FLEX-5000, so it is important that you have the latest Firewire driver and firmware loaded for your radio as well. It is also assumed that you have VAC and your virtual COM port program properly configured.

In this procedure we are assuming that you have your software defined radio and PowerSDR properly communicating and are using the most current versions of PowerSDR. The configuration of VAC’s parameters other than the audio and PTT are outside the scope of this article.Ĭonfiguration Overview and Required Software The intent of this article is to describe in detail the setup and configuration of N1MM for voice keying with PowerSDR.
