THE CLUBHOUSE BULLETIN
Band conditions for the week ahead, the contest weekend, and who is glowing gold. One short email a week, written by operators for operators. Free, and no spam ever.
PROPAGATION — ARE THE BANDS ALIVE?N0NBH
Reading the sun…
High flux is good. Low A and K are good. When A climbs, the polar paths close and the low bands get loud.
The ARRL Propagation Bulletin continues in memory of Tad Cook, K7RA.

THE CLUB, HEARD ON THE AIRGreyline owners SPOTTED in the live cluster and RBN streams
Watching the wires for club callsigns…
Every gold callsign spotted in the last few minutes, newest first. This pane keys on operators being HEARD — call CQ and get spotted and up you come; spotting others does not list you. Click a call for its QRZ page, or hit RBN to sieve the skimmer firehose for that operator. Quiet is normal — the bands decide, not us.
SPACE WEATHER & THE AURORAL OVALScurated after Jose CT1BOH · imagery from NOAA SWPC

AURORAL OVAL · NORTH POLE
NOAA OVATION aurora forecast, northern hemisphere: the auroral oval over the north pole
AURORAL OVAL · SOUTH POLE

When the ovals swell, the polar paths close and the low bands get loud. Curated after the reference page of Jose CT1BOH, who teaches this very subject at Contest University. A nod to the masters, always.

RBN — THE CW PULSElive skimmer firehose via Reverse Beacon Network

Sampling the skimmer firehose…
What this pane is: a live sample of the RBN telnet firehose. If you call CQ and forty skimmers answer over the next minute, this window catches the ones that crossed the wire while it was listening. For the full picture — every skimmer, the distances, the map — use the link above. It is RBN's own database, and it is better than anything we could rebuild here.

Same as RBN: the chips are a recent slice, the map is the whole story. PSKReporter asks that data be pulled no more than once every five minutes, so that is exactly what we do — they give this away free and we are not going to be rude about it.
CWOPS — THE CW OPERATORS CLUBcwops.org · 3,000+ members, nearly 100 countries
CW ACADEMY — LIVE TEACHERS, A REAL CLASSROOM, NO CHARGE
Volunteer advisors, small classes, a real syllabus, and a path that runs from never-touched-a-key to high speed. If you have ever said "I should learn CW," this is the door. It is the single best thing in amateur radio that nobody charges for.

THE CWT — FOUR EVERY WEEK
WED 1300Z
WED 1900Z
THU 0300Z
THU 0700Z
In North America the last two land Wednesday evening and Wednesday night local — which is why most US operators call it four every Wednesday. One hour each.
HOW IT WORKS
One hour, come and go as you please. Exchange is your name and CWops number if you are a member, or name and your state, province, or DX prefix if you are not. No log submission required — report at 3830scores.com.

You do not need to be a member and you do not need to be fast. Send at the speed you have; good operators slow down for you. That is the culture.
CWT rules and details →
A 24 foot flagpole and a hundred watts is a perfectly respectable CWT station. The CWT is where you find out that the thing holding you back was never the antenna.

THE GRAY LINEour namesake
Twice a day the terminator sweeps your QTH — and for those minutes, low-band signals ride the boundary between day and night ionosphere with absurdly low loss. 160M and 80M openings that shouldn't exist, do. That's the gray line. It's why we're named Greyline.

Every CQ World Wide winners circle back to 1948, kept by Jose Nunes CT1BOH — the same operator who teaches propagation at Contest University. Seventy-odd years of who won, on what band, from where. This is why it is fair to call it radio sport: it has a record book.
