Digital Nets in Mississippi
How to Get Started in the Digital Modes
Current Atmospheric Conditions and Maximum Usable Frequency
Mississippi Digital Amateur Radio Club (MS-DARC) is composed of Amateur
Radio Operators, who are dedicated to furthering the understanding
and use of the digital modes in Mississippi, for both pleasure and
digital modes also offer some new things you might be interested in
doing: like have a keyboard-to-keyboard text QSO with someone, similar
to using internet chat rooms and instant messaging; or send (and receive)
messages to/from Bulletin Board System (BBS) for storage, retrieval,
and forwarding; or send (and receive) email from your radio through
the airwaves to a gateway station located in another state that places
it into the internet email system for you; or by-pass the internet altogether
and send (and receive) email (with attachments) straight from your radio
to another Ham's radio (Peer-to-Peer) while your radio is unattended;
or send and view digital video transmissions on your TV; or create a
wide-area, high speed, self discovering, self configuring, fault tolerant,
wireless computer network using an amateur radio frequency. During an
electrical/phone/internet outage you could still share documents, forms,
email, photos, video, view members web-pages, talk to each other on
the phone using Voice Over Internet Protocol (VOIP).
Just imagine all the possibilities and uses the digital modes can give you!
the immense value of the digital modes for emergency communications,
the MS-DARC is seeking to establish standard practices and procedures
for digital emcomm in the Mississippi. To that end we are dedicated
to establishing reliable, NVIS, point-to-point, repeater independent,
Internet independent, Digital Amateur Radio operation on VHF and HF
frequencies within the state of Mississippi and to it's neighboring
states. The MS-DARC endorses the use of the Narrow Band Emergency Messaging
System, the WinLink 2000 System, Packet, and BroadBand HamNets for emergency
Mississippi Digital Amateur Radio Club (MS-DARC) encourages you to check
into one or more of our weekly Digital nets. They each have a different
purpose and format, but are all geared to helping beginners learn the
basics of digital communications so they can participate. Click on the

3. Digital VHF/UHF Nets in Mississippi:
In addition to the above mentioned HF nets the MS-DARC also sponsors VHF/UHF Simplex Nets and VHF/UHF Repeater Nets throughout the state:
SCARES-NBEMS Net: The Scott County ARES Team is planning to hold a digital emergency communications training net on the Pelahatchie Repeater every other week and on a 2 meter simplex frequency on the alternate weeks. Details on our website.
4. Digital HF Email Nets in Mississippi:
The Mississippi Peer-to-Peer Email Net runs all day on Tuesdays
taking email check-ins from 9:00 am - 9:00 pm. Check-ins are done by
preparing an email in RMS Express and initiating a Peer-to-Peer contact
with our Net Manager's Station (K1REZ) which will be monitoring the
following frequencies: 9:00 am to 4:00 pm: 7078.4 USB dial frequency
on the radio. (Center Freq. 7079.9 USB on RMS Express)
4. Digital VHF/UHF Email Nets in Mississippi:
In addition to the above mentioned HF Email Net the MS-DARC also sponsors VHF Simplex Email Nets.
SCARES- P2P-EmailNet: The Scott County ARES Team is planning
to hold their own email via radio net on a VHF simplex frequency every

I. ADVANTAGES OF DIGITAL MODES:
Great for reliable rag-chew, DXing, Paper Chasing, emergency communications. Many modes - choose your mode depending on conditions. Bottom of the solar cycle - works well, even under very poor conditions where phone QSO's would be impossible!. It's FUN
II. EQUIPMENT REQUIRED:
1. Computer with a Monitor: FlDigi will run on Windows, Mac, and Linux. If you also want to send/receive email via radio you will need RMS Express, which runs on Windows versions XP through Windows 8.
2. HF Transceiver and/or VHF/UHF Transceiver: Any rig with a digital read-out that goes down to the 1 hz range, or any rig that is very stable. Most modern rigs have auxiliary jacks in the back. If not, you will at least need an audio output line (external speaker) and a microphone input line. Of course you will need a power supply and Antenna (For statewide emcomm purposes an NVIS antenna is recommended)
3. Soundcard Interface: The plug-n-play, defacto standard sound card interface is the SignaLink USB. Currently $109.99 and well worth it considering it allows you into the digital world and email via radio world!!!
