CQ Contests: CQ WW | CQ WPX | CQ WW RTTY | CQ WPX RTTY | CQ 160 | CQ VHF

Apr 20

Bob Wilson N6TV did some analysis using new columns in the raw data archived by the Reverse Beacon Network.

We finally have an answer to that age old question, “So, how fast do people send Morse code in CQ WW CW?”

Answer:  about 30 WPM

Shown below is the average CW speed of all the RBN spots, by continent (of the DX).
Those African DXpeditioners really know how to QRQ (especially EF8U).  And yes, most slow down a bit on Sunday, even if conditions improve:

Do people send slower on the low bands?  Yes, the lower the band, the slower they go.

Map showing typical RBN data

The RBN collects data from receivers around the world and stores it into a database. These reports include call, frequency, signal-to-noise ratio, and CW speed. More information about the Reverse Beacon Network is available at http://www.reversebeacon.net/
