| MISC INFO HF via HT
|Hello from Len // N8AD in Erie, Pa
The information below rambles on and
on a LOT! Sorry about that, but I
wanted to put almost all the important
information that I have in ONE SPOT.
Use it for your reference for things that
may appear unanswered anywhere else.
|D T M F CONTROL
FULL CONTROL VIA LOCAL
REPEATER OR DUPLEX LINK.
If You run EchoLink, MixW with
CAT control of your HF radio,
and lastly ARTiE, you will be
able to control your HF radio using
your DTMF pad and Touch Tones
EchoLink does not need to be
connected to the internet, it just
needs to be present and running
so that ARTiE can exist. Of
course it is better that EchoLink
can connect to the world via the
internet, it's just not necessary.
Once MixW is capable of
controlling your radio via CAT,
EchoLink's internal DTMF
decoder will decode your touch
tones received via your Link or
Repeater, and pass the string of
touch tones to ART. ART in turn
will digest the code and if it is a
correct one, will let MixW
execute the corresponding
command. (Of course this assumes
that you have a repeater or link
already properly interfaced to
EchoLink, and it can decode touch
In effect when you are in range of
your Link or Repeater you will be
able to send commands to place
MixBASE in the RECEIVER
MODE, TRANSCEIVER MODE,
or just REPEATER MODE. (You
can NOT be on a simplex link.)
In the RECEIVER MODE you will
be able to change frequencies to
any that your radio is capable of
going to. All commands will begin
with a pair of "A's", which act as
an attention prefix. Frequency
changes are "AA" followed by
FIVE digits. If you have used the
CHAT TEXT box on N8AD's
system, you already understand
the 5 digit convention. Above
10Mhz just enter the KHz desired,
such as AA14313, AA21390,
AA28330 etc. Below 10 MHz start
the frequency portion with a
ZERO. 7233 Khz would properly
be entered from DTMF as
"AA07233". 3898 KHz would be
"AA03898" and so on.
Besides frequency entries via
DTMF you can also enter memory
channels. If you have set your radio
up accordingly, there are 100
available memories with
ARTiE. They range from 7001 to
7099. And of course they begin
with "AA" ATTENTION signals.
So to enter memory channel 50,
which on most ART systems
corresponds to 5.000 Mhz AM.
You would send "AA7050" Notice
4 numbers. This is the reason that
frequencies below 10 MHz all
start with a ZERO, 7050 could be
channel 50, or 7.050 Mhz, which
would cause a lot of confusion for
users calling CQ on top of WWV 5.
Besides Direct Frequency Entry
and Memory Channel Entry, there
is overriding mode entries.
By convention direct frequency
entry will place the radio in proper
MODE settings. A QSY to 14300
from 3840 will change from LSB
to USB automatically. You can /
must have the power to override
this if necessary. So it too is
available from touch tone control.
AA11 is LSB, AA12 is USB,
AA13 is CW, AA14 is AM, and
AA15 is FM.
The ability to place the system into
RPTR/RCVR/XCVR modes is also
available. AA01 is RPTR,
AA02 is RCVR and AA03 is
XCVR. AA00 is STOP, which will
also place it in RPTR as a
We discussed Direct Entry of
frequencies, and they will provide
whole KHz entry. To fine tune to
the nearest 100 Hz, are 2 other
commands, AA?B and AA?C.
AA?B, where ? = a number from 0
to 9 moves up 100Hz X ?. So if
you were to send AA4B, for
example, you would move from the
present frequency, say 14300 to
14300.4 KHz. AA9C, on the other
hand would then move you down
100Hz X 9 or to 14299.5 KHz
from the last entry.
Want to know what frequency you
are on presently, Which is a good
idea if you plan to do any
transmitting. Simply enter the
command 'AAAA" and K1RFD
will reply with the present
Frequency and Mode. AA10
will send the time of day.
If you set your radio up to comply
with our convention,you will place
the 10 meter FM repeater pairs
with proper splits in memory
channels 7061 thru 7069.We have
standardized this to be, if a user
sends "AA7064" for example, the
radio will be set to memory channel
64. Channel 64 will be pre-
programmed to contain 29.640 for
receive, 29.540 for transmit,
SPLIT will be activated, and the
FM mode will be selected. This
standardization is important to us,
and makes operation of 10 FM
easy for all involved.
Channel 7060 DTMF "AA7060"
places you on 29.600 FM simplex.
The national calling frequency.
Memory channels are very useful,
as you can see for providing splits
PL's and offsets that are not
otherwise easy to do from the
field. Numbers below 40 are pretty
much reserved for REPEATERS
on VHF and UHF, for just this
Since you are also on a VHF/UHF
system, you might not want a
non-informed user setting direct
entries on these bands.
It would be disastrous for
someone to transmit on your
control frequencies. Memory
channels let you select what can be
used in these dangerous areas.
(It also keeps desense issues to a
Similarly, we have chosen that 60
meter channels be set up on 7091,
7092, 7093, 7094, and 7095. With
non standard Modes of USB
Channel 99 is saved for NOAA or
weather radio broadcasts if you
location and radio are so equipped.
There could be more in the near
future...If you have a need for
something that everyone might
want, drop us a note with the
request for your desired function.

|Hints for proper operation...
The MixBASE system on N8AD-R is
composed of three separate elements.
1...It is a Repeater system that
simultaneously sends the active audio
on RF . Please listen to "something"
if you use the system. DON'T just let
it play NOISE!
2...It is a RECEIVER that also
streams audio over eQSO, SKYPE,
and PORTRAIT. Be sure to turn the
system ON with the ON command,
then send the RCVR command via
3....It is a TRANSCEIVER if you are
entered into the XCVR, Control Ops
4...When you are finished with a
session, be sure to turn off the
system, if you entered commands to
use it. Enter STOP, OFF, or QUIT to
stop the receiver, and return it back
to REPEATER control.
5...If you connect and you are the only
user on EchoLink, do not be alarmed
if the receiver is ON. The repeater
also offers full control via Touch
Tones, and we use it all the time to
keep audio playing for all the
"Listeners" on other systems.
Feel free if there are no EchoLink
users already, to tune it to whatever
6...If you connect via EchoLink and
there is another station(s) already
there...Do not steal the system away
from previous users. There is only
one radio, and one user at a time that
should control it.
7...You can speak over Streaming
Audio from the receiver if the system
is in the RCVR mode. Send "TALK"
in Chat to mute the audio. When you
finish transmitting send "LISTEN" to
reset the audio stream.
8...EchoLink will not allow the
EXACT line of Chat Text to be
duplicated within a 30 second period.
It will ignore a duplicate entry! This is
a primary reason to use EZPAD or
the ART-DX download GUI's.
9...Shut off your CHAT TEXT
CHIME. If you receive a DING
whenever a line of Chat Text is
received, it would be wise for you to
shut it OFF, before it drives you
crazy. (Same with the You are
DOUBLING WITH message.)
10...eQSO also streams this station's
audio. If you intend only to Listen it
would be considerate of you to do so
from eQSO since it will not use
bandwidth from me. If you want to set
a frequency to listen to, you must
remain in EchoLink. The room to
connect to in eQSO is the
11...SKYPE is also available and is
connected to, one user at a time, by
dialing "hfremote". Both SKYPE and
eQSO are not monitored locally by
anyone (except only occasionally).
12...Don't ask for XCVR privileges
unless you have downloaded ART-DX
or EZ-PAD and have figured out how
to use them from a RECEIVER
standpoint first. All users can do
everything up to the XCVR command
without needing approval.
13...If you are in the Control Op data
base and intend to use the transmit
functions...BE SURE your audio is as
perfect as it can be. Voice peaks must
go to YELLOW on the Audio Meter
of EchoLink without going full scale!
Failure to talk it UP to this level will
result in LOW OUTPUT from the HF
POOR AUDIO from you will result in
really TERRIBLE AUDIO on RF.
14... This system can do ALL
DIGITAL MODES ! Using
REALVNC VIEWER 4, you can even
do SSTV etc.
15...There is a delay from the time the
HF station says OVER until your
audio can return to HIM over the air.
This is due to EchoLink and can not
be entirely eliminated. Set your
RECEIVER HANG TIME to 300ms
and reduce your NETWORK and PC
BUFFERING to minimum values that
will still provide good audio that does
not break up. (The best it can be
reduced to is about .6 seconds.) The
station on HF can respond to you
immediately, and does not have any
delay to consider. Your response to
him will be delayed, only! He does
NOT have to drag HIS feet when
returning to you.
|Normal System Operation Instructions.
If no one is already in CONTROL...
1...SEND "ON" in CHAT or
CLICK the ART-DX "ON"
2...SEND "RCVR" or CLICK it.
3...SEND a FREQUENCY in 5
DIGIT format such as 14300,
FINE tune using 03950.123 etc
or if using ART-DX click the EZPAD
button above the MAIN TUNING
dial of the radio, and use it to set
the BAND and frequency.
4...Send COMMANDS or click
ART's buttons. Proper syntax is
required if you use CHAT.
5...When finished....SEND STOP !!!!
6...Disconnect for others to use
DON'T LISTEN TO STATIC...SHUT
IT OFF IF YOUR NOT GOING TO
TUNE IT TO A STATION! KEEP IT
IN THE HAM BANDS ONLY,
and DON'T USE IT FOR SWLing.
