[ARC5] The GF Transmitter- A Short Essay

[David Stinson]

Please plug this into the essay, at the beginning of 
paragraph 6, before "The GF-7/RU-9 (1938)".
I accidently left it in the last paragraph.
So much for my proof-reading ;-)

-------------------
The only other single-frequency-range transmitter set
in this series was the GF-6/RU-8, produced for the 
Naval Reserve in 1938. 
The GF-6 transmitter covered 2000-4525 KC.
The RU-8 receiver did have multiple coils, but only for
the LF Radio Range band, broadcast band and 2000-5600 KC.
