I joined the meeting of a ham in Kochi yesterday.

There were about 100 ham members.

I was able to meet some ham members.

We were able to know each other.

I made 50MHz band ANT

The other day, I made the antenna of a 50MHz band.
I was able to communicate with the HAM radio station of JA8 area (Hokkaido) today using the antenna.
The distance is about 1400 km. (Kochi-Hokkaido) 
I think It was propagation by a Es layer.

From now on, it is a season of Es. lovely
