[[WSPR_PROTOCOL]]
|
||||
==== WSPR
|
||||
|
||||
WSPR is designed for probing potential radio propagation paths using
|
||||
low power beacon-like transmissions. WSPR signals convey a callsign,
|
||||
Maidenhead grid locator, and power level using a compressed data
|
||||
format with strong forward error correction and narrow-band 4-FSK
|
||||
modulation. The protocol is effective at signal-to-noise ratios as low
|
||||
as –31 dB in a 2500 Hz bandwidth.
|
||||
|
||||
WSPR messages can have one of three possible formats illustrated by
|
||||
the following examples:
|
||||
|
||||
- Type 1: K1ABC FN42 37
|
||||
- Type 2: PJ4/K1ABC 37
|
||||
- Type 3: <PJ4/K1ABC> FK52UD 37
|
||||
|
||||
Type 1 messages contain a standard callsign, a 4-character Maidenhead
|
||||
grid locator, and power level in dBm. Type 2 messages omit the grid
|
||||
locator but include a compound callsign, while type 3 messages replace
|
||||
the callsign with a 15-bit hash code and include a 6-character locator
|
||||
as well as the power level. Lossless compression techniques squeeze
|
||||
all three message types into exactly 50 bits of user
|
||||
information. Standard callsigns require 28 bits and 4-character grid
|
||||
locators 15 bits. In Type 1 messages, the remaining 7 bits convey the
|
||||
power level. In message types 2 and 3 these 7 bits convey power level
|
||||
along with an extension or re-definition of fields normally used for
|
||||
callsign and locator. Together, these compression techniques amount to
|
||||
“source encoding” the user message into the smallest possible number
|
||||
of bits.
|
||||
|
||||
WSPR uses a convolutional code with constraint length K=32 and rate
|
||||
r=1/2. Convolution extends the 50 user bits into a total of (50 + K –
|
||||
1) × 2 = 162 one-bit symbols. Interleaving is applied to scramble the
|
||||
order of these symbols, thereby minimizing the effect of short bursts
|
||||
of errors in reception that might be caused by fading or interference.
|
||||
The data symbols are combined with an equal number of synchronizing
|
||||
symbols, a pseudo-random pattern of 0’s and 1’s. The 2-bit
|
||||
combination for each symbol is the quantity that determines which of
|
||||
four possible tones to transmit in any particular symbol
|
||||
interval. Data information is taken as the most significant bit, sync
|
||||
information the least significant. Thus, on a 0 – 3 scale, the tone
|
||||
for a given symbol is twice the value (0 or 1) of the data bit, plus
|
||||
the sync bit.

.FT8 DXpedition Mode:
|
||||
|
||||
- This special operating mode enables DXpeditions to make FT8 QSOs at
|
||||
very high rates. Both stations must use _WSJT-X_ Version 1.9 or
|
||||
later. Detailed operating instructions for {ft8_DXped} are available
|
||||
online. Do not try to use DXpedition mode without reading these
|
||||
instructions carefully!
|
||||
|
||||
IMPORTANT: FT8 DXpedition mode is suitable for use only by legitimate
|
||||
DXpeditions and those attempting to work them. Do not try to use
|
||||
DXpedition mode for normal FT8 operation. Do not use it in the
|
||||
conventional FT8 subbands. And especially, do not use the
|
||||
multi-signal capability unless you are a DXpedition.
|
||||
|
||||
IMPORTANT: When finished with this Tutorial, don't forget to re-enter
|
||||
your own callsign as *My Call* on the *Settings | General* tab.
