For now, we'll allow click-to-decode in ISCAT mode.

some features of the decoder will likely change. In most ways
operation of QRA64 is similar to JT65.
=== Meteor Scatter with MSK144
=== MSK144
Meteor-scatter QSOs can be made at any time on the VHF bands, at
distances up to about 2100 km or 1300 miles. Completing a QSO takes
longer in the evening than in the morning, longer at 144 MHz than at
50 MHz, and longer at 2000 km than 1500 km. But with patience, at
least 100 Watts, and a single yagi it can usually be done.
Meteor-scatter QSOs can be made any time on the VHF bands at distances
up to about 2100 km (1300 miles). Completing a QSO takes longer in
the evening than in the morning, longer at higher frequencies, and
longer at distances close to the upper limit. But with patience,
100 Watts or more, and a single yagi it can usually be done.
- Select *MSK144* from the *Mode* and *Fast* from the *Decode* menu.
Unlike other _WSJT-X modes, MSK144 decodes received signals in real
time. Decoded messages will appear on your screen almost as soon as
you hear them.
- Set the audio receiving frequency to *Rx 1500 Hz*, frequency
tolerance to *F Tol 100*, and T/R sequence duration to 15 s.
- Select *MSK144* from the *Mode* menu.
- MSK144 decodes received signals in real time, so you will see
decoded messages almost as soon as you hear them. To match decoding
depth to your computer's capability, click *Monitor* (if it's not
already green) to start a receiving sequence and observe the
percentage of CPU usage displayed on the _Receiving_ label in the
Status Bar:
- Select *Fast* from the *Decode* menu.
- Set the audio receiving frequency to *Rx 1500 Hz*.
- Set frequency tolerance to *F Tol 100*.

able to keep up at these settings; in that case there will be a modest
loss in decoding capability for the weakest pings.
- T/R sequences of 15 seconds or less make it sometimes desirable to
advance your selection of transmitted messages very quickly. Check
*Auto Seq* to have the computer make the necessary decisions
automatically, based on received messages.

- For operation at 144 MHz or above it is advantageous to use the
short-format messages for Tx3, Tx4, and Tx5. Check the box labeled
*Sh* to enable this feature.
For operation at 144 MHz or above you may find it it helpful to use
short-format messages for Tx3, Tx4, and Tx5. These messages are 20 ms
long, compared with 72 ms for full-length MSK144 messages. Their
information content is a 12-bit hash of the two callsigns, rather than
the callsigns themselves, plus a 4-bit report, acknowledgment, or
sign-off. Only the intended recipient can decode short-messages.
IMPORTANT: There is little need to use MSK144 *Sh* messages at 50 or
70 MHz, where most pings are long enough to support the standard
MSK144 message length.
- Check *Sh* to enable short messages.
IMPORTANT: There is little or no advantage to using MSK144 *Sh*
messages at 50 or 70 MHz. At these frequencies most pings are long
enough to support standard messages.
