|Fritz Bauer started building transmitters bearing his name in 1955. His first
product was a 1 kW transmitter designed for export. In 1959, the FCC decided to
allow Class IV (Now Class C) stations to operate with 1 kW in the daytime.
Bauer, along with Bob Hammett, Ed Edison, and Paul Gregg, saw the potential need
for 1200 transmitters, capable of operating at 1000 and 250 watts. This brought
to birth in late March 1960 the famous Bauer 707 transmitter. The plan was for
the transmitter to be assembled by the local engineer, and then factory
personnel would come out and test it. Over 400 were sold in ten years, some of
them still in service. The kit was so well made that one 707 was even assembled
on the NAB show floor by a Kelly Girl!
Among the many firsts for the Bauer companies were the first transmitter with solid state rectifiers, the first solid state FM transmitter, and more.
Bauer also manufactured audio consoles, and was an early maker of torroid RF samplers for antenna current sampling.
Granger & Associates bought Fritz Bauer' Company and it was later merged into Sparta-Cetec. The company variously operated under the names Granger, Sparta, Cetec and Elcom Bauer (with Jim Lawrence "L-Com"). Founder Fritz Bauer retired in 1960 and died in 1961. Another founder, Paul Gregg, operated the company in El Paso from 1993 until his death in May 2014. Parts and documentation are said to be via Goodrich Enterprises.

The FB-1000J was the first commercial model Fritz made -- previous transmit-ters were always re-builds or converted police band transmitters. Fritz made some of the FB-1000J's in Woodside, Cal. before he moved to San Mateo. The FB-1000J was always made in the "garage". He built about 25 over the years, usually one at a time.
