Hi Stefan,

bombastic signal again, easily decoded after the first partial transmission.

Maybe the over-eager watchdog also had a beneficial side: By protecting VO1NA's transmission slots, Joe could be decoded here every single hour:

EbNauters,

Last night something went wrong. The first message started at 01:30, the last one at 05:30 UTC. The watchdog actually seems to cut off after 33 minutes. Seems it was adjusted for OP32 messages in the past. So probably the last 30 % of the message is cut.
A higher challenge for those who will try to decode the message.

Hi Rob and Jay,

Thanks for the reports. Nice to see that the path to Rob can be crossed as well. But we are quite close to the limit.

Jay, very nice copy. And yes, last nights message should have decoded easily, even if the SNR would have been 10 dB lower!

The forecast looks good for tonite. Do you like to try a 50 character message with me? Does your PC have enough RAM for 8K21A? With 8 GB it should work.
