Listed here are a few common mistakes newbies and
sometimes experienced WSJT operators make.
We all realize no one is going to be perfect and mistakes are
going to be made. After all FSK441, WSJT and
propagation mode meteor scatter are new and have to be learned
and operating procedures can be corrected
when errors are pointed out.
- Common
WSJT Mistakes: Sending each message from Tx1
to Tx 5 in sequential order regardless
of what has been received. The Standard
Operating Procedures should be followed for three primary
reasons:
1) improves completion / failure ratio 2) shortens qso
time 3) received messages will be in order expected. To
avoid this mistake, study the SOP and use the F5 Key to
see what should be sent nextduring a contact.
- Common
WSJT Mistakes: Giving up on a schedule too
soon. Dont expect to hear meteor
bursts each
sequence and unless you have problems, give at least 20
minutes minimum for each schedule made. Patience is
required for meteor scatter contacts especially longer
distances.
- Common
WSJT Mistakes: Using Single Tone Messages or
Short Hand Messages on call frequencies.
This
will eventually cause confusion on shared frequencies and
could put your contact in question as well as frustrate
or
wreck another qso on the same frequency. To avoid this,
dont use Single Tones of Sh Messages on the calling
frequency.
Adapt the messages Ts3 Tx5 with the other stations
Prefix or Suffix.
- Common
WSJT Mistakes: Discussion relating to what is
being sent or received during the contact attempt in
real time on the Ping Jockey Page. The
problem is it disqualifies the contact making it invalid.
The solution is to keep
all contact details as to what is being sent and received
to yourself until the contact is completed or abandoned.
This is a good
practice even if you have worked the station many other
times.
- Common
WSJT Mistakes: Expecting to work stations out
of normal meteor scatter range. The
recognized
normal distances for meteor scatter or in the range of a
few hundred miles up to 1200 miles. Most contacts will be
less
than 1150 miles. Contacts are possible further distances
but they are rare and best tried during major showers
with a
high ERP station.
- Common
WSJT Mistakes: Using non-standard
reports. This generally confuses other
stations that are expecting to
decode either 26 or 27 for reports. It is best to stick
with the standard reports, especially if you plan to use
single tone messages.
- Common
WSJT Mistakes: Not calling the qso complete
unless 73 is send and received. The
Standard Operating
Procedures clearly state that both stations should only
receive Rogers. (R27 / R26 or RRR i.e. Roger XX
or Roger Roger Roger )
- Common
WSJT Mistakes: Failure to adjust RIT and to
reduce tol based on decoded text DF. The
first ping decoded
will indicate a DF. Adjust the RIT in Hz by indicated DF
in Hz and turn the tol down to 100. (If using JT6M adjust
tol to 50
or 25Hz) These adjustments will help WSJT decode received
pings better and improve your success.
- Common
WSJT Mistakes: Mistake or typo in entering
the callsign of the other station in the To Radio Pane.
Everyone
has probably done this before and when told or noticed
adjust on the fly. The other station cannot progress to
the next message
until he has both calls correct.
- Common
WSJT Mistakes: Calling CQ on frequency other
than the recognized calling frequency. Many
stations
now listen on 144.140 or 50.260MHz for FSK441 meteor
pings. Calling cq is good but do it where others listen.
- Common
WSJT Mistakes: Listening to the call
frequency for hours and giving up because "I don't
hear anything". Working random
contacts is hard. It is best to start off with a real
time schedule on the Ping Jockey with a stations between
600 - 1000 miles apart.
