These are the working conditions of 

19 DD 301

My radio is a Yaesu FT-757GX.
It's an old radio that I bought secondhand in 1998. The RF output is approximately 100 watts PEP.
I use a Kenwood MC-60 dynamic microphone.

My radio is powered by a Yaesu FP-757HD. It is also connected to my computer for digital communication.
I use the following software for digital translation:
CWGET110 and TRTTY160.
I'm still looking for an automatic antenna tuner FC-757AT.

I use a 2 element Quad antenna that stands 11 meters above the ground.
The antenna has the following specifications:
Power multiplication factor   7.9
Gain                       9 db
Front-to-back rejection      30 db

I use a channelmaster to rotate my antenna.
