PRIMER- Weak Signal
(WSJT) modes on 6m

Guide to HF JT65A

50 MHZ WSJT
COMPOSITE STANDINGS

JT65 Terrestrial Link.

Purpose: These procedures are published to aid those operators wishing to use WSJT Modes for working ( TEP or Sporadic
E Skip) during the Es season (summer especially)

WHY :WSJT will make contacts often times not possible with SSB or before SSB is possible during an opening. These
signals can often times be heard although weak and constant or often times not heard at all. Using JT6M contacts can be
completed in short order with full confidence on both ends that the contact meet all requirements for a legitimate completion.

Who: These standards were arrived at by sharing emails with a few experienced EU / NA operators who have experience
making dx contacts. ( G4PCI ; G4IGO : K1SIX ; W5UWB ; N5SIX & WA5UFH )

Frequency:
50.230 MHz & 50.260 MHz are the recommended calling frequencies for (Es) JT6M. All stations should use the "Off-Set" method
of calling CQ. These two frequencies are the Eu and NA calling frequencies. Check both during suspected openings.

NOTE: NA Stations when using 50.230 MHz should use "UP" offset only to avoid crowding the SSB operators that might be working above
50.200 MHz. Operators should avoid using offsets that end up on Frequency 50.260 (Meteor Scatter / Es Calling Frequency) & 50.290 MHz
(PSK31)

50.255 MHz is the recommended calling frequency for JT65A. Stations will also find it best / beneficial to make schedules for this mode on the
Terrestial JT65 page via Ping Jockey Pages. ( You may need to find a person on PJ Central and then qsy to Terrestial JT65 page } HF JT65A
stations with six meter capabilities are encouraged to try the "magic band".

Transmit Period:
The western most station transmits first. (Same as meteor scatter procedures) EU always 2nd when attempting contacts in NA or Caribbean.

Reporting System:
The users has some flexibility. European stations expect to see EU defaults thus we recommend that NA stations swap user options
to EU Defaults using 26 or 27 reports. Random Hour messages used on shared frequencies in NA should be avoided as EU not
used to these messages. The important thing is to receive both calls and exchange either standard reports (26 - 27) or your grid square
or a valid contact

Internet Loggers:
Default Logger is Ping Jockey

1. CQ U7 W1AW (Up 7KHz from calling frequency) W1AW will listen on 50.237 MHz and swap their Tx Frequency from
50.230 MHz to 50.237 MHz after receiving a call.

2. CQ U50 W1AW (Up 50 KHz from calling frequency) W1AW will listen on 50.280 and swap their Tx Frequency
from 50.230 MHz to 50.280 MHz upon receiving a call)

3. CQ 250 W1AW (Up 20 KHz from calling frequency) W1AW will listen on 50.250 and swap
their Tx Frequency from 50.230 MHz to 50.250 MHz upon receiving a call)

Assuming K1JT is calling CQ on six meters 50.260MHz during an Es opening...
1. CQ D10 K1JT (Down 10 KHz from calling freqeuncy) K1JT will listen on 50.250 MHz and swap their Tx Frequency from
50.260 MHz to 50.250 MHz after receiving a call.
