"Click on a digital mode below to hear a brief sample of the sound these modes make. Hopefully this page will help you identify a mode you've heard (or help me identify ones others have heard!). Many folks have submitted excellent quality, lengthy files which are no trouble for me to accept, but I do generally drop the sampling rate and length to make them more reasonable to download over a slower line. The intent here is more for recognition by ear than for signal analysis. My page focuses on what hams call "Utility" modes or "Utes". Additional amateur radio mode links are at the bottom of the page."

"When Microsoft came up with Vista (and all later versions of Windows), they decided to change the location of folders (directories) where users should put "their" data. In contrast to earlier windows version (like XP) the 'Documents and Settings' folder ('Dokumente und Einstellungen' in german) has gone. Instead, there should be folder for each user in the root of drive C.
Much worse, any directory in the former 'Programs' folder, where Spectrum Lab and including ALL its subfolders used to be installed by default, doesn't have write permission for users without an admin account. There may be good reasons to do this, but the ugly consequence is that you cannot have 'all in one place' anymore, and that you cannot make a copy of an installed Spectrum Lab, including all of its (possibly modified) configurations by copying for example C:\Programs\HamRadioSoftware\SpectumLab (including all subdirectories) anymore !"

"The Audio-I/O-Libraries are a simple way to send uncompressed audio streams from one application to another. At the moment, both applications must run on the same PC. The first Audio-I/O-Library (in_AudioIO.dll, written in March 2008) was a shared windows DLL, which could be loaded into Winamp, and acted as an audio-bridge between the author's Spectrum Lab and Winamp (see last chapter in this document). The purpose was to send an MP3-encoded audio stream from a radio receiver to the web, using Winamp + Oddcast for the audio streaming, and Spectrum Lab for the audio pre-processing."

"In addition to the 'normal' wave-file logging routine implemented in Spectrum Lab, there is the possibility to save audio streams in disk files triggered by certain event"

"The FiFi-SDR is a small software defined radio with an integrated USB soundcard. It contains a programmable VFO, using the Si570 (programmable oscillator chip). As an (almost) fully assembled kit, including the preselector board, the SDR was available for 130 Euros in 2012 at the german Funkamateur Verlag"

"This program started as a simple FFT program running under DOS a long time ago, but it is now a specialized audio analyzer, filter, frequency converter, hum filter, data logger etc (see history). You can download it from this site. Or look into the manual (in HTML format), even though the manual included in the archive will be more up-to-date. Furthermore, the same manual has occasionally been converted into a single PDF (SpecLab_Manual.pdf), but any attempt to create a common index and table of contents for this PDF, using OpenOffice (with proper page numbers instead of the hyperlinks) has failed miserably - see note in the preface of the PDF document."

"Finnix is a self-contained, bootable Linux CD distribution ("LiveCD") for system administrators, based on Debian. You can mount and manipulate hard drives and partitions, monitor networks, rebuild boot records, install other operating systems, and much more. Finnix includes the latest technology for system administrators, with Linux kernel 3.0, x86 and PowerPC support, hundreds of sysadmin-geared packages, and much more. And above all, Finnix is small; currently the entire distribution is over 300MiB, but is dynamically compressed into a small bootable image. Finnix is not intended for the average desktop user, and does not include any desktops, productivity tools, or sound support, in order to keep distribution size low."

"The PC has to support booting from a USB flash/pen/key drive. There may be anywhere from 1-3 items to change in the BIOS to make this possible assuming your BIOS supports it. Some bios's may refer to your flash drive as a USB floppy or USB zip. Of course there are exceptions, perhaps some are covered here. The USB flash drive must support booting from it in general.
3. The flash drive must contain the boot/system files. The flash drive must have bootsector area. This is done with special utilities. References to "A:" drive lines in the autoexec.bat and/or config.sys files you copy to the drive after you make it bootable may result in errors. You "may" have to format your floppy disk first in WinXP before you create a bootdisk as XP may "not" like working later on with a disk formatted otherwise. Included below is a bootable ISO of DOS 7.1 which may be used with some of these methods if you do not have a 1.44 drive."

"Some machine, e.g. Asus Eee PC or Acer Aspire One, comes without CD/DVD drive. In this case, an USB flash drive or USB hard drive is the best way to boot Clonezilla live. You can follow the following to make a bootable Clonezilla live USB flash drive or hard drive using either MS Windows or GNU/Linux."

"Clonezilla Live is a small bootable GNU/Linux distribution for x86/amd64 (x86-64) based computers. Clonezilla SE (Server Edition) has been developed from 2004, and it is used to deploy many computers simultaneously. It is an extremely useful tool, however, it does have several limitations. In order to use it, you must first prepare a DRBL server AND the machine to be deployed must boot from a network (e.g. PXE/iPXE). To address these limitations, we have combined Debian Live with Clonezilla as "Clonezilla Live," a software that can be used to easily image and clone individual machines. The primary benefit of Clonezilla Live is that it eliminates the need to set up a DRBL server ahead of time and the need for the computer being deployed to boot from a network. Clonezilla Live can be used to image or clone individual computers using a CD/DVD or USB flash drive. Though the image size is limited by the boot media's storage capacity, this problem can be eliminated by using a network filesystem such as sshfs or samba."

"Retired military members and certain honorably discharged veterans may wear the US Military uniform on certain occasions. This authority is authorized by Federal law (10 USC, 772). It allows certain veterans and retirees to wear the US Military uniform, as prescribed by the individual services."
