SOI

Signal Operating Instructions (SOI) aid in the operation of a net. By establishing common operating frequencies, modes, and schedules, members can more easily find one another.

Net Frequencies are established as channels indicating frequency and mode of operation.

Channel definition nomenclature: Channels ending in P, S, or T are primary, secondary, and tertiary voice channels. CW is permitted there if necessary but digital is not. Channels with an F are digital channels, indicating the band and the channel number. Channels with C are defined as a channel by outside authority, as on 60 meters.

A new macro package is coming soon. Download the current FLDIGI macros (ZIP). Unzip the archive and place the MDF file in your FLDIGI macros directory, then use FLDIGI's File>Macros menu to load the macros.

Procedures (including prowords and prosigns) can be found in

Schedule

Our operating schedule is defined by "Activation." See the Activation page for Warnings (advising of possible upcoming activation) and Notices (advising of activation) for detail.

Summary of current monthly training operation schedule from the present Activation follows. All times are local Ohio time.

60 Meters

We begin mid-day operations on 60 meters, and use these channels for interoperability with government stations. We start on Channel 4, and move up to avoid interference, to 5, then to 1, then 2, then 3. Amateur stations have secondary privileges on this band and must yield to government stations.

These channels contain USB (dial frequency likely shows -1500 Hz from emission centers listed here), digital, and CW. Use your rig's channel definitions.

  • 60C4 emissions centered at 5373 kHz

  • 60C5 emissions centered at 5405 kHz

  • 60C1 emissions centered at 5332 kHz

  • 60C2 emissions centered at 5348 kHz

  • 60C3 emissions centered at 5358.5 kHz

75 Meters

We typically start with voice control on 75 meters, except for mid-day or when we need government station interoperability, when we start on 60 meters. Operators on 75 meters may move up or down 1 kHz to avoid interference; if more space is needed, fall back to another channel. Move further than 1 kHz only when none of the three channels can be used without interference and another and is not suitable.

  • 75P 3847.5 kHz LSB

  • 75S 3947.5 kHz LSB

  • 75T 3962.5 kHz LSB

80 Meters

We use 80 Meters for digital and most CW operations. Voice is not permitted here. These channels are defined by the (suppressed) carrier frequency USB; emissions are centered at 1500 Hz up.

  • 80F1 3578.5 kHz USB

  • 80F2 3581.5 kHz USB

  • 80F3 3583.0 kHz USB

  • 80F4 3584.5 kHz USB

  • 80F5 3586.0 kHz USB

  • 80F6 3587.5 kHz USB

  • 80F7 3589.0 kHz USB

  • 80F8 3590.5 kHz USB

40 Meters

We use 40 Meters for Digital (40F-), Voice (40[PST]), and CW (40-). 40F- are specified as suppressed carrier frequency USB; emissions are at 1500 Hz up.

  • 40F1 7079.5 kHz USB

  • 40F2 7081.0 kHz USB

  • 40F3 7082.5 kHz USB

  • 40F4 7084.0 kHz USB

  • 40F5 7085.5 kHz USB

  • 40F6 7087.0 kHz USB

  • 40F7 7088.5 kHz USB

  • 40F8 7090.0 kHz USB

  • 40P 7182.5 kHz LSB

  • 40S 7207.5 kHz LSB

  • 40T 7212.0 kHz LSB

Common Procedure Signals

The BLACK SWAN Net uses formal procedure words (prowords) for telephony and procedure signals (prosigns) for teleprint heavily to convey precise instructions or meaning, aiding in efficiency. The full sets of prowords and prosigns can be found in the Allied Communications Publications (ACP) 125(G) and 131(F), respectively.

Prowords are not written and prosigns are not voiced. Use the procedure to match the mode of operation. Do not write "ROGER," send QSL. Do not say "Q-R-M," say "Interference."

Leading signals

  • INT - Interrogatory, used as a leading signal to turn the signal into a question

  • ZUG - Negative, used as a leading signal to negate the next signal

Abbreviations and Short Signals

  • C - Confirm, see also Y

  • K - Over, I am finished transmitting and am listening for you

  • N - Negative

  • R - Roger, I understand your transmission - not the same as yes

  • Y - Yes, affirmative, see also C

  • AS - Wait

  • AR - Out, I am terminating the contact

  • DE - This is, introduction of station identification

  • 73 - Best regards

  • IMI - also ? - Say again, or I say again (for correction or emphasis)

  • BULL - Message for all stations in the net

  • BCAST - Message for broadcast transmission

Z Signals - Mostly for Net Operations

ARRL National Traffic System (NTS) QN signals are incompatible with international signals and are not to be used on 60 meters, where U.S. Government stations may be interoperating.

  • ZBO - Traffic: (quantity) (precedence) (target), e.g.,
    N2LC DE KD8TTE ZBO 1 P WD8SAB

  • ZBR - Send your traffic (to...) using:

    • R - Direct Method, i.e., ZBRR

    • F - Broadcast Method, i.e., ZBRF

  • ZEV - Message acknowledged, e.g.,

    • INT ZEV - Request acknowledgement

    • ZEV - I acknowledge message

    • ZUG ZEV - Do not acknowledge

  • ZKA - Identification of Net Control

  • ZKB - This net is directed, c.f.,
    ZUG ZKB - This net is free - not the same as closed, see ZKJ

  • ZKD - Take control of net

  • ZKE - Reporting into the net

  • ZKJ - Close down - leaving this frequency (may be going off-air), e.g.,
    BLACKSWAN DE KD8TTE ZKJ K - Closes the net by telling all stations to close down
    KD8TTE DE N2LC ZKJ K - (net control) (this is) (calling station) I am closing down

  • ZNB - Authentication, e.g.,

    • INT ZNB AB - What is the authentication of AB (voice equivalent: AUTHENTICATE AB)

    • ZNB C - Authentication is C (voice equivalent: I AUTHENTICATE C)

    • ZNB C INT DE - Mutual authentication: authentication is C, what is the authentication of DE

    • ZNB ABC - Used for message authentication without challenge, as part of instructions: authentication of AB is C.

  • ZVR - Relay to subordinate stations (or nets)
