Red face DR111 with external active antenna

A late start because I was out earlier in the morning. Here also 98.8% decoded audio during the 120 minutes I logged - and that is including the TX break minutes before 11 UTC. 26 dB SNR with the DR111 is a very impressing result over a distance of more than 17000 km!

Although the label says Yaesu, I assume it's just a rather common error. Indeed, the DR111 is a nice little receiver despite some flaws and limitations.

DR111

The band opened around 09 UTC and I got 99% decoded audio for the 161 minutes left until the end. A mostly unattended log because I had to leave just before 11 UTC.

DR111

Miserable in my part of the world today. Even "the best part" (the last hour) suffered a glancing blow...

PS: Must be a record sunspot number today? SSN:234 (!)

DR111

A bit better this morning (with the AC socket pulled out from my Samsung QRM generator)... but not as good as expected.
