Curated station logbook
Recorded mail examples
These selected exchanges demonstrate Winlink mail in both directions. Follow a role link for audio, waterfall, packet inspection and decoded traffic. This logbook contains only the selected examples.
A single data-loss incident cost the project significant development work and logbook material. Among the losses were the high-speed VARA receive recording and the original rig receive recordings for these ARDOP sessions. These examples use the recordings and session records that survived.
| Example | Participants | Date | Band | Mail result | Recorded speed |
|---|---|---|---|---|---|
| VARA mail send | W9SSJ ↔ NS0A | 2026-09-27 21:21 UTC | 40 m | 1 sent · destination receipt confirmed | L9 acknowledged transmit |
| VARA mail receive | W9SSJ ↔ N5TW | 2026-09-23 18:10 UTC | 20 m | 2 received · 1 sent | L4 receive · speed-limited |
| PACTOR-3 mail send | W9SSJ ↔ VE1YZ | 2026-09-24 04:10 UTC | 40 m | 1 sent · 2 received | SL6 acknowledged transmit |
| PACTOR-3 mail receive | W9SSJ ↔ WS8EOC | 2026-10-03 05:00 UTC | 80 m | 1 received | SL3 receive |
| ARDOP mail send | W9SSJ ↔ WW2MI | 2026-08-23 03:11 UTC | 40 m | 1 sent · destination receipt confirmed; subsequent receive failed, END not confirmed | 4FSK.200.50S TX · 4PSK.200.100 RX |
| ARDOP mail receive | W9SSJ ↔ W6IDS | 2026-08-26 15:24 UTC | 40 m | 3 received · normal link close | 4PSK.200.100 receive |
VARA receive is a retained L4 example. PACTOR-3 receive is SL3. “Acknowledged transmit” comes from the original session acknowledgments; independently decoded audio coverage is shown in each inspector.
The ARDOP audio comes from remote KiwiSDR witnesses. WW2MI used a 200 Hz session; W6IDS used 500 Hz. After the WW2MI send completed, a receive-parser failure left three offered messages unfetched and END unconfirmed. The W6IDS receive completed with a normal link close.
