About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images
and text used on the RF Cafe website are hereby acknowl My Hobby Website: |

Stenode Corporation of America Advertisements |

Stenode tubes were a big deal in the early 1930s, and were deemed capable of changing fundamentally the way high selectivity receivers and transmitter preamplifiers would be designed. History had other plans for RF circuit design. Note that both advertisements include the signature of Stenode tube inventor Dr. James Robinson. See articles Stenode's Selectivity Revolutionary and The Stenode Radiostat System. Stenode Corp. of America Ad on Page 109
