DATARADIO OPERATION
FOREWORD
PACKET RADIO has propelled Amateur radio into the era of com puters with a
quantum leap. Because of this rapid move into the world of digital
communications, there are many new hams entering the hobby for the express
purpose of using these dicital modes that make use of the Outputer and
associated software. AS a result of this rapid growth, many of these new
amateurs found that it would require the use of the FM mobile unit, or a
second VHF tran sceiver to access the large variety of Packet applications
that exist, includ ing; keyboard to keyboard networks, switches, nodes, DX
spotting nets, BBSes, conference clusters, and much more enjoyment centered
around the use of Packet radio. With many of these Packet systems, the user
can connect to distant sta tions in other cities, states, and coun tries
using low powered transceivers. There is no need for super powered
transceivers that run hundreds of watts.
Packet Radio is a mode of communications which makes use of a “store and-
forward” technique called; AX.25 r … tocol. This format provides error
through-put of both ASCII, and binary, text or data between stations that are
connected using the AX.25 protocol.
ALINCO attends hamfests throughout the United States, and the world. One of
the subjects that seem to be on the mind of many Packeteers is: Where can they
find an economical tran sceiver that will function well when used in the
digital, or Packet modes?
ALINCO LISTENED TO YOUR RE QUESTS, and ALINCO has respond ed with the kind
of transceiver that is designed with the Packeteer in mind. First of all, the
DR-1200T is engineered to provide optimum audio characteris tics for the Mark
and Space tones of
1200 and 2200 Hz. By using this ap proach with both the transmit and receive
circuits, the DR-1200T can be utilized with both 1200 and 2400 bps. The same
high quality is built into the DR-1200T DataRadio as with all other ALINCO
products, yet the cost of the DataRadio had to be considered, because for many
Packet users this would be a second transceiver. In order to make the DR-1200T
DataRadio more economical, the DR-1200T comes without a mobile mounting
bracket, microphone, or accessories that are not needed in a Packet Radio
environment. This does not mean the DataRadio is not suitable for use with FM
voice operation.
As a matter of fact, the DR-1200T per forms well in voice applications. An
accessory kit that includes the micro phone, and mobile mounting bracket is
available as an option for the DR-1200T DataRadio.
INTERFACING YOUR ALINCO DR-1200 TO THE TNC
In an ettort to minimize the new DR-1200 DataRadio owners time put ting the
station on the air, ALINCO is including the necessary interface cable with the
transceiver connector already installed. This means that only the connector
for the TNC end is needed to put the Packet station on the air. Many TNC
manufacturers in clude the TNC connector as one of the supplied accessories.
Pin out connections for the DataRadio 1/0 connector are listed below. These
connections are already wired and soldered at the DataRadio connector (female)
end of the cable. The color coded wires identify the appropriate TNC signal
connections.
Note:
If hum or noise is experienced on the transmitted packet signal, disconnect
the shield connection at the TNC end of the cable. The gray wire at pin 8 will
provide ground return for the PTT line, and no other ground are necessary. As
an added benefit, ALINCO is supporting the new DR-1200 DataRadio owner by
including some drawings that illustrate examples of how the DR-1200 is
interfaced to many Packet R!3.dio, Terminal Node Controllers (TNC).
Before beginning the interface, and setup procedures that are discussed in the
next portion of this manual, it is recommended that you read the ap pendices
in the final section of this manual. This will familiarize you with the
transceiver, and best of all you will discover the many wonderful features
that are a part of your ALINCO DR-1200 DataRadio.
Packet Operation of the ALINCO DR-1200 DataRadio
Using the interface configuration for your TNC, connect the DR-1200 to the
TNC. Your TNC should already be in terfaced to your Data Terminal Equip ment
(DTE). The DTE can consist of a “dumb” terminal, or a computer with the
appropriate terminal software loaded. The TNC should be configured for the
correct hand-shaking between the computer/terminal, and the TNC. Most
computers use “hardware” hand-shaking. If this is true in your sit uation,
then set the TNC XFLOW to OFF. If you are using “software” hand shaking, then
set the XFLO to ON. To begin operation of your Packet sta tion, there are
other TNC parameters .which may need setting. As a rule tb= TNC manufacturer
will supply t ) TNC with “DEFAULT” parameters which are acceptable. As you
become familiar with your new station, and with the ALINCO DR-1200, you may
determine that some adjustments of the TNC parameters are needed.
Before continuing; install your callsign into the TNC. At the command prompt
(cmd:), enter your callsign in the fol lowing manner: MYCALL [Your Call) .<
Enter>
DR-1200 PIN NUMBER | WIRE COLOR | TNC Function |
---|---|---|
1 | YELLOW W/Black Sleeve | AFSK OUTPUT |
2 | RED Push:ToTalk | PTT Control |
6 | ORANGE Rx AF | RECEIVE Audio |
7 | SHIELD | Shield/Ground |
8 | GRAY Ground | PTT Ground |
Note:
Callsign installation may differ in some TNCs.
For openers we will set a few of the TNC parameters as follows:
TXDelay 30 to 40 (milliseconds)
TXD 35 is optimum for the DR-1200. In most applications, you may find that
even faster TX Delay times are accept able. This is because the ALINCO
DR-1200 DataRadio has a very rapid receive to transmit transition period.
The following parameters are sug gested, however, the TNC may have default
parameters which can func tion without modification or change.
FRack 4 SCReenl O MCOM ON MCON OFF DWait 16 MRPT ON Still other TNC parameters
can be set .Jit the users system, and mode of operation. It should be pointed
out that these settings may also depend on the make and model of your termi
nal, and in some cases, the software.
Ensure that an antenna, set for the VHF Packet portion of the band, is at
tached to the DR-1200. Make sure the DR-1200 is on the packet frequency that
you wish to use, and check the transceiver “shift” or offset to be sure it is
set correct. Most Packet systems operate in the simplex mode, thus, there are
no offsets and no “shifts” used.
If you are unable to contact a local Packet Users Group, or fellow pack eteer
to assist with your first contact, then try one of the national throughput
frequencies like 145.010 MHz.
■ NOMINAL SETTINGS
In tests we’ve run on many TNC’s, we’ve found that setting the volume control
pointing to the left, or to 9:00 O’clock, will provide ample receive audio for
decoding data by most TNC.
As you become familiar with the tran sceiver and TNC, you may observe that
less receive audio is needed … or in a few instances, your TNC may require
slightly more AF.
The squelch is set to a point where no noise (white/shot noise) is received
through the speaker of the DR-1200T, or indicated by the DCD lamp on the TNC.
Under normal operating condi tions, we’ve noticed that a setting of 12:00
O’clock is sufficient to keep the noise subdued until a packet signal is
present.
■ RECEIVING PACKET SIGNALS
Another way to set the volume and squelch with the TNC is to make all the
correct interface connections, and with the system on and in the receive
operating mode, turn the volume up about one fourth turn, or to about ten
O’clock. Open the squelch by turning it all the way counter-clockwise. until
noise is heard. While watching the DCD, RCV, or CONV. LED (depending on the
manufacturer) on the TNC. assuming the DCD lamp is illuminated, turn the
volume control down until the DCD LED is no longer lit. Now slowly turn the
volume control until it again il luminates. To be sure there is ample AF
drive to the TNC, move the volume control slightly, more clockwise. This will
ensure that enough audio is present to provide optimum data decoding.
■ REMEMBER; TOO MUCH AUDIO IS AS BAD AS NOT ENOUGH!
Next turn the squelch up (clockwise) until the DCD LED extinguishes or goes
off. As with the volume, close the squelch slightly more clockwis ) be sure
there is a solid squeicn threshold.
If you are on a packet frequency, and there are packet signals present, your
DR-1200T should be hearing the packet signals. If the terminal is connected
and the TNC is properly configured, your station should be printing text on
the screen or to the printer, if one is present.
■ TRANSMITTING PACKET
To operate (transmit) a packet station you should have a current amateur
radio license that allows operating privileges within the spectrum that your
DR-1200T is tuned to.
If the interface cables are properly wired and connected then we are ready to
establish contact with another Packet station.
It is wise to solicit the help of anotl person who is already operating in the
Packet modes. This way you will have someone who can listen for your sig nal
,and guide you into the operating frequencies that are used for Packet in you
ares.
Although the ALINCO DR-1200T DataRadio is engineered to make use of limiting
circuits that are designed to prevent over modulation (deviation), there are
some TNCs which may drive the transmit audio circuitry too much.
An indication that a problem such as this is present, would be noticed when a
connect is tried to a nearby Packet station with no results. Often too much
transmit deviation can cause the same problem as not enough transmit audio.
The best audio level Setting has been found to. be in the large of 3.5 kHz to
4.5 kHz swing.
All TNC,without exception, have provi sions within their circuitry that
allows the user to increase, or decrease the AFSK level(s) when necessary. It
is advisable to have knowledge of which component inside the TNC, controls the
audio output as it may be neces sary to make an adjustment to the associated
level control(s).
Remember; this is the exception, and not the rule, less than 20 percent of all
TNCs will require any adjustment at all.
■ ADDITIONAL INFORMATION
To turn off audio signal from a speaker, you can plug dummy load as below.
