Enquiry
“In my historical research I am trying to establish the relationship between these two companies: Wulfsberg and Collins. Reportedly, Mr Wulfsberg held a senior managerial post with Collins in the 1960s. He is believed to have established his own radio company in 1970, which still exists, albeit under a different name according to the website listed below. canyonaeroconnect.com/our-history/. Is this factual?” — Jan SP5XZG • 73
The first edition of this research note stated the Sundstrand acquisition as 1984. The Canyon AeroConnect official history and the Avionics News profile both indicate the correct year is 1986. This note is corrected throughout.

The Wulfsberg Name in 1960s–1970s Aerospace
Second-edition research identifies at least four distinct Wulfsbergs active in the US aerospace and radio industry during the 1960s and early 1970s. Carefully distinguishing between them is essential for accurate historical research:
Individual |
Affiliation / Evidence |
Relationship to Wulfsberg Electronics |
|---|---|---|
| P. G. Wulfsberg | IEEE document, 1963: “Collins Radio Co. Cedar Rapids, Iowa.” Kansas records: Paul G. Wulfsberg, Overland Park KS. NASA document, 1970: King Radio Corporation, Olathe KS. | Almost certainly the Paul G. Wulfsberg who founded Wulfsberg Radio in 1970. Career trajectory: Collins Radio (c.1963) → King Radio (c.1970) → Wulfsberg Radio (1970, founder). |
| Arthur F. Wulfsberg | IEEE History Center oral history: Collins Radio Company, Apollo programme communications, alongside engineers Pickering and Vale. | A different individual from Paul G. Wulfsberg; possibly a relative (common Wulfsberg family in the Kansas/Iowa region). His Collins Radio connection is to the Apollo space programme, not commercial avionics. |
| K. N. Wulfsberg | IEEE journal papers: “Sky noise measurements at millimeter wavelengths” (Proc. IEEE, 1964); atmospheric attenuation studies (Radio Science, 1967, 1973). Affiliation: atmospheric/propagation research, not commercial avionics. | No apparent connection to Wulfsberg Electronics or Collins Radio commercial avionics. A researcher in the electromagnetic propagation field, active at a government or academic laboratory. |
| Paul G. Wulfsberg (President) | Kansas manufacturing directory: “WULFSBERG ELECTRONICS… PRES: PAUL G. WULFSBERG.” Address: 11300 West 89th St, Overland Park, KS 66214. | Confirmed president/founder of Wulfsberg Electronics. Street address confirms Overland Park founding location, ~5 miles from King Radio in Olathe (400 N. Rogers Rd., Olathe, KS 66061). |

Figure 1. Revised career trajectory hypothesis for Paul G. Wulfsberg, incorporating new evidence from the second edition. Items marked ★ require independent source verification.
This trajectory is consistent with several known facts. Collins Radio and King Radio were not merely competitors — Ed King’s first company manufactured components for Collins Radio from 1948, and both operated within the same Kansas City metro–Cedar Rapids avionics industry ecosystem. An engineer moving from Collins to King Radio in the 1960s, and then departing to found his own company five miles from King Radio in 1970, would be a career path typical of the entrepreneurial avionics industry of that era.
Wulfsberg to Canyon AeroConnect — Confirmed Corporate Succession
Year |
Company Name |
Event & Details |
|---|---|---|
| 1970 | Wulfsberg Radio | Founded by Paul G. Wulfsberg in Overland Park, Kansas (11300 West 89th St, Overland Park, KS 66214). First product: the FliteFone — world’s first airborne telephone system. Grew into aviation’s first 2-way FM tactical radio systems. |
| 1970s–1986 | Wulfsberg Electronics | Independent operation. Name evolved to Wulfsberg Electronics; Paul G. Wulfsberg confirmed as president. Products: Flitefone 40, Flitefone VI, RT-series multi-band tactical radios. FliteFone becomes registered trademark. |
| 1986 | Global Wulfsberg Systems (Sundstrand) | Sold to Sundstrand. Sundstrand merges its Global Navigation division with Wulfsberg to form Global Wulfsberg Systems, Inc. (GWS). Operations relocated to Prescott, Arizona.1,2 |
| 1994 | AlliedSignal Aerospace | Acquired by AlliedSignal Aerospace. Prescott facility closed; operations moved back to Olathe, Kansas — five miles from original location. Chelton Avionics later acquires all rights to Wulfsberg product lines plus the former Bendix Series III nav/com line. |
| 1997 | Chelton Avionics | Acquired by Chelton Avionics. Prescott, Arizona operations re-established. Develops RT-5000 series (5,000+ units sold) and RT-7000. FlexComm II system introduced. FliteFone is a registered Chelton trademark. |
| 2009 | Chelton / Wulfsberg + NAT | Northern Airborne Technology (NAT) — formerly dB Systems and Pentar — integrated. Cobham Aerospace Connectivity becomes the parent entity. |
| 2021 | Canyon AeroConnect | Following Advent International’s acquisition of Cobham Aerospace Connectivity (January 2021), the business is rebranded as Canyon AeroConnect, operating from Prescott, Arizona as a subsidiary of Chelton Avionics, Inc. / TransDigm Group Inc. Canyon AeroConnect carries the Wulfsberg, NAT, and Chelton product heritage forward. |
The Collins Radio — King Radio Connection
The Wikipedia article on King Radio Corporation establishes an important context:
This is significant context for understanding the Wulfsberg–Collins relationship. King Radio was not merely a competitor of Collins Radio — it began as a Collins Radio supplier, and both companies operated within the same tightly connected Kansas City metro / Cedar Rapids avionics industry ecosystem. The Collins Radio / King Radio / Wulfsberg triangle can be visualised as a cluster of companies with overlapping personnel, technologies, and business relationships, rather than independent competitors. A person working at Collins in Cedar Rapids in 1963 and then at King Radio in Olathe by 1970 would have moved within the same industry community, not jumped to a foreign company.
This also explains why a Wulfsberg connection to “Collins” might be reported when the more recent employment was at King Radio: to someone outside the industry, Collins Radio and King Radio were deeply intertwined Kansas/Iowa avionics companies, and the distinction between them (especially in hindsight, after King was acquired by Allied/BendixKing) could easily be elided in oral history.
Wulfsberg Electronics — Technical Product Legacy
Product |
Description & Era |
|---|---|
| FliteFone / Flitefone | World’s first airborne telephone system (1970). Successive generations: Flitefone 40, Flitefone VI. Air-to-ground VHF radio telephone for corporate and helicopter applications. FliteFone is a registered trademark of Chelton Avionics / Canyon AeroConnect. |
| RT-series multi-band radios | RT-9600, RT-138, RT-450 — FM/AM airborne tactical radios. Evolved into the RT-5000 (29.7–960 MHz AM/FM, P25 capable, 5,000+ sold) and the RT-7000 (current Canyon AeroConnect flagship). |
| FlexComm II | Multi-band synthesised FM/AM transceiver family under Chelton Avionics ownership. Covers 29.7–960 MHz. Used in law enforcement, SAR, EMS, and military helicopter applications. |
| C-5000 / CD-5000 Control System | Control head system for Wulfsberg multi-band radios. The RT-5000SAR was designed to accept either the Wulfsberg C-5000/CD-5000 or a Collins CDU controller — indicating deliberate Collins interoperability in the product design. |
Research Resources — Priority Verification Targets
The following table (sourced from a research resources summary compiled for this note) identifies the primary research avenues for verifying the outstanding claims, ordered by research priority.

Location / Access |
Relevance |
|---|---|---|
| Collins Radio Company Records (MsC 814) | University of Iowa Special Collections — in-person only, Iowa City IA. aspace.lib.uiowa.edu/repositories/2/resources/719 | Primary source for Collins employment records. Series I Administrative Files includes employment applications and correspondence. A name search for “Wulfsberg” in this collection would confirm or deny Paul G. Wulfsberg’s employment and role. |
| Avionics News Profile (February 2002) | wulfsberg.com/PressReleases/ (RTF file — server timeout during research). Cache may be available via Wayback Machine: web.archive.org | Full biographical profile of Paul Wulfsberg. The portion retrieved confirms his status as a “genius” of aviation communications; the complete document may explicitly name Collins Radio and/or King Radio as prior employers. |
| Canyon AeroConnect Corporate Communications | Prescott, Arizona. canyonaeroconnect.com/contact/ | As the corporate successor to Wulfsberg Electronics, Canyon AeroConnect carries institutional memory of the company’s founding history. A direct enquiry about Paul Wulfsberg’s pre-1970 employment is the most likely route to confirmation from a living institutional source. |
| NASA Technical Reports (1970) | ntrs.nasa.gov — searchable. Search for “Wulfsberg King Radio” or “Paul Wulfsberg Olathe” | AI-assisted research identified a NASA Langley document listing “Paul Wulfsberg, King Radio, Olathe, Kansas” as a contact. If confirmed, this places Paul Wulfsberg at King Radio in 1970 and corroborates the King Radio → Wulfsberg Radio departure hypothesis. |
| Kansas Aviation Historical Society | Wichita / Olathe area. No confirmed web presence found; contact through the Exploration Place science museum, Wichita, or the Mid-Continent Airport museum. | Regional oral history archives covering the Kansas City / Wichita avionics industry cluster (Cessna, Beechcraft, Learjet, King Radio, Wulfsberg). Most likely source for personal biographical detail on Paul Wulfsberg’s career before 1970. |
| USPTO Patent Records | patents.google.com/?inventor=paul+wulfsberg | Paul G. Wulfsberg holds patents on FM frequency synthesiser design (Radaris confirms a synthesiser patent). Patents assigned before 1970 would identify his employer at the time of filing; patents after 1970 should be assigned to Wulfsberg Electronics. |
Five Most Productive Next Research Steps
- 1IEEE Xplore — verify P.G. Wulfsberg at Collins Radio, 1963 — Search ieeexplore.ieee.org for “P.G. Wulfsberg” or “P. G. Wulfsberg Collins Radio”. An IEEE paper with an affiliated author listed as Collins Radio, Cedar Rapids, Iowa, circa 1963, would confirm or deny this claim directly from the primary source. IEEE membership may be required for full access to older papers.
- 2NASA NTRS — verify Paul Wulfsberg at King Radio, 1970 — Search ntrs.nasa.gov for documents citing “Wulfsberg” or “King Radio Olathe” from 1969–1971. The NASA Technical Reports Server is fully searchable and free. Confirmation from a NASA Langley document would be a strong primary source.
- 3Wayback Machine — retrieve full Avionics News profile — The Avionics News RTF file at wulfsberg.com was inaccessible. The Wayback Machine (web.archive.org) may hold a cached version. Search for
wulfsberg.com/PressReleases/. This is the single most likely publicly available document to contain Paul Wulfsberg’s full career history in his own company’s words. - 4University of Iowa Collins Radio Archive (MsC 814) — Series I name search — An in-person visit to the Special Collections at University of Iowa Libraries, Iowa City, is required. Request a search of Series I (Administrative Files, Employment Applications and Correspondence, 1933–1963) for the name “Wulfsberg”. The employment applications file spanning to 1963 is potentially the most direct evidence. Contact: lib.uiowa.edu/sc/.
- 5USPTO Patent Records — Wulfsberg employer pre-1970 — Search patents.google.com with date filter before 1971. Any patent filed before 1970 by Paul G. Wulfsberg will show the assignee (employer); a pre-1970 patent assigned to Collins Radio or King Radio would definitively confirm that employment.
