SHERWOOD SOUND BYTES
Rob has several operating positions but "this one" not only shows his favorite position, it also depicts some of the messages he tries to share with the thousands of people who follow his research.
With all those multi-thoushand dollar transceivers to choose from, in most of his presentations, Rob still raves about the ergonmics of the IC-781 and the fun he has using this transceiver. This picture also shows that your ham radio dollars, first and foremost should be invested in the antenna system, not in the radio. (See his antenna farm, here: SHERWOOD FOREST
It also tells me that Rob must be in my age group because like me, he uses a microphone out of the 1950s, a loud speaker with filters in order to hear better, and a cheat sheet to enhance the short-term memory when tuning the linear! (hi)
You will find more pictures in the NC0B Photo Gallery. (still under construction)

SSB-01 Transceiver Performance
In this SSB, Rob explains that there are many other features and characteristics of a transceiver than just its DR3 ranking.

SSB-02 Do not overate Dynamic Range (DR3)
This comment was made to the Ten-Tec Eagle group, thus the frequent mention of Ten-Tec.
In this SSB rob stresses once again that DR3 is not the only aspect of a transceiver that we should consider in our choice of radios.
