DV setup, consists of entering call signs in 4 fields - MYCALL, URCALL, RPT1 and RPT2.

MYCALL ­You normally enter your own callsign in MYCALL and never have to change it as long as you use the radio.

URCALL - This is simply the station you want to call. Or, to call anyone you enter CQCQCQ

RPT1 - This is the callsign of your local repeater that is within your radio’s reach. If you move to a different city then change this to the local repeater you can access over there.

RPT2 - Is used open a gateway to contact people beyond your local area or beyond your band.

A few examples will help illustrate their usage using W4LDG D­STAR repeater on 444.475 MHz, +5MHz offset.

(a) SIMPLEX OPERATION
MYCALL
= N4FNB (my callsign)
URCALL = CQCQCQ or W4VGI (callsign being called)
RPT1 = blank
RPT2 = blank
Select a simplex FM frequency, switch the radio mode to DV, make sure no one is using the frequency, and press PTT and give out your call sign. If anyone is within range and want to respond they will. That’s it!


(b) BASIC REPEATER OPERATION
MYCALL = N4FNB (my callsign)
URCALL = CQCQCQ or W4VGI (callsign being called)
RPT1 = W4LDG B (callsign of repeater on 440 MHz band)
RPT2 = blank
Tune the radio to the repeater’s frequency and offset just like you would do for any repeater, press PTT and announce your call sign. In this example, stations listening to the repeater on the same (UHF) band will hear the call.


(c) CROSS BAND REPEATER OPERATION
MYCALL = N4FNB (my callsign)
URCALL = CQCQCQ or W4VGI (callsign being called)
RPT1 = W4LDG B (callsign of repeater on 440 MHz band)
RPT2 = W4LDG C (callsign of repeater on 144 MHz band) Note: D­STAR repeaters can be setup to operate on several bands simultaneously. So, in this example, stations
listening to the repeater on the both the 440 MHz band as well as the 144 MHz band will hear the call.


(d) CALLING ON REMOTE REPEATERS VIA GATEWAY
MYCALL = N4FNB (my callsign)
URCALL = CQCQCQ or W4VGI (callsign being called)
RPT1 = W4LDG B (callsign of repeater on 440 MHz band)
RPT2 = W4LDG G (callsign of gateway)
In this example, a general CQ call can be heard by stations listening to any of the linked repeaters on any of the bands supported by their repeaters. A call to a specific callsign will prompt the system to route your call to the repeater and band where the callsign was last heard.


(e) ECHO TESTING ON THE LOCAL REPEATER
MYCALL = N4FNB (my callsign)
URCALL = CQCQCQ (general call)
RPT1 = W4LDG B (callsign of repeater on 440 MHz band)
RPT2 = W4LDG E (callsign used for the echo function)
When you press PTT and say something like “<callsign> echo test”, the repeater will echo back the voice it heard. Most D­STAR repeaters offer this convenient test feature that helps to confirm radio settings and voice quality. These examples should make it easy to understand the configuration of the D­STAR radios. Also, observe that
some cases shown above illustrate some convenient features not generally possible on regular repeaters. These are, in fact, some of the biggest feature change when using D­STAR system.

That’s all there is to it. Remember only four entries - MYCALL, URCALL, RPT1 and RPT2 control everything. MYCALL and RPT1 remain unchanged if you remain in the same area, URCALL is simply the destination you are
trying to call and RTP2 is based on the feature being used.

Lastly, to use the gateway and other features, your call sign has to be registered in the D­STAR system, once. Search the internet or navigate to www.dstarusers.org and identify the local D­STAR repeater in your area, and navigate to the repeater website and sign up your call sign on their web site. Once confirmed, you can use the entire D­STAR system to make some really interesting contacts in distant
countries.

After successfully mastering these modes, you will be well on your way to enjoy the more advanced features of this new exciting area of amateur radio. Congratulate yourself, you deserve it!
BASIC SETUP TO OPERATE A DSTAR RADIO OVER THE W4LDG GATEWAY REPEATER
N4FNB    -      AMATEUR RADIO STATION
If you have a DSTAR radio, then "Nifty E-Z Guide to D-Star Operation is a must read.  This book is well written and walks you through all types of set ups for contacts in the DPLUS G2 gateway system.  The Icom manuals do not reference any Dplus setting becuase Dplus is not an Icom product, but has been developed by Hams in the last few years. 
You may not have much knowledge of DSTAR operations now, but a few short hours with this book and you will improve you skills and enjoy that new radio much more than you thought.  The examples are clear and walk you step by step through all the various settings.  Mine stays on my operating table as a constant reference book.  After a few weeks, you will have all the setting the way you like and most of your operating will be changing from one memory setting to another.  For under $15, it is a great investment and will help you get the most out of your new DSTAR radio.   For more information, click on the book.
While you are waiting on your Nifty E-Z Guide to DSTAR Operation to arrive, I have included some basic instructions for operating through the W4LDG gateway repeaters.  Don't be afraid to connect to some of the reflectors.  Plenty of QSOs out there by connecting to reflectors like REF030C in Atlanta.  This is one of the busiest reflectors in the DSTAR system.  There is always someone on the side ready for a QSO.  If you want to work some DX, connect to REF001C to get an international taste of DSTAR!  To connect to the reflector set URCALL to REF030C with RPT 1 set for W4LDG  B and RPT2 set for W4LDG  G.  As soon as the repeaters link, change the URCALL back to CQCQCQ before you make a call.  If you don't want to talk, connect and listen.  Enjoy and use the W4LDG DSTAR repeater system.
