About the group
Founded 1995
Started by Allan (originally 26 DT 001, now 153 DT 001) in Preston, Lancashire. The group motto is “It’s Good to Talk”.
International membership
Members and unit numbers across many countries. The public directory lists historical and current records; “active members” on this site refers to recent participants and is a smaller figure. DT callsigns are optional identifiers within the hobby community—they do not replace any radio licence your country requires.
Current activities
On-air nets (including the North West Net), radio camps, QSL exchanges and the members directory.

Member experiences
Short notes from the airwaves (examples of the kind of contacts and events members share).
First DX contact
“Worked a station in France on a good skip day using a simple dipole. Confirmed with an eQSL the same evening.”
North West Net
“The monthly net is a friendly check-in. New operators are welcome — just give your call and location.”
Radio camp
“Great to meet faces behind the callsigns, try different antennas, and keep the log busy all weekend.”
