• Ongoing discussion at dual circuit. Needs clarifying but getting an agreement is like swimming through treacle
• See what can be done to rescue Electrical telegraphy in the United Kingdom for FA.
• Network synthesis for FA?
• Improvements to Baghdad battery from this source

• /Two and a half
• interrupter. Started as a Golding Bird spinoff but needs expanding, it is very unbalanced as it is. Some info at Peter Cooper Hewitt, Nicholas Callan, Arthur Wehnelt, Charles Grafton Page, List of Nikola Tesla patents. Applications mentioned at Christmas lighting technology, electric bell, contact breaker
• Frequency response. [1] has made the article very unbalanced towards audio.
• Power dividers and directional couplers might be wise to extend to fibre-optic devices if going for FA. Hard to argue against as the article now covers waveguide and fibre is a form of waveguide. Now also a comment on the talk page about integrated photonics.
• The opening of Morse code history section has a couple of problems. There is a false comparison between Morse beginning development and Cook and Wheatstone putting into service. Cook and Wheatstone were in fact first. Also, much of the Cook and Wheatstone part is a bit of a diversion from the article subject
• /List of polynomials used in filter design
• /Hourglass filter
• Infinite networks
• Fringing field
• Electrical impedance#Measurement needs some work - network aanalyzer, impedance analyzer, Smith chart. There is also scope for creating the redlinked impedance analyzer which has some incoming links. /impedance analyzer.
• Gollum Channel and Whittard Canyon. See Porcupine Seabight and Submarine canyon
• /History of maritime signal flags

Arbitrary break 4

• Guide wavelength and guide cutoff frequency
• Matthaei chapter 14 has some material that could usefully be added to diplexer (ring resonator type in stripline + see also to appropriate section of waveguide filter article.
• /finline, currently redirects to waveguide filter
• Microwave components, currently redlinked. Not explicitly covered in Electronic components
• launcher redlinked in slotted line
• Transfer conductance, transfer impedance. Redlinked in Electrical element.
• Parasitic coupling, currently redlinked. Linked in Via fence.
• Fringing field, redlinked in Via fence
• System-on-a-package, currently redlink. [2] distinguishes this from both System-in-a-package and mult-chip module.
• Card rack
• voltage/current magnification unhelpfully redirect to LC circuit.
• Ricochet battery [3]
• Transversal filter, and tapped delay-line filter. And tapped delay-line, perhaps all redirecting to one article.
• impedance inverter, [4] explains J and K inverters quite well. Matthaei also has something, but not explained very well. Existing links: gyrator, negative impedance converter, positive impedance inverter.
• Mobility (mechanics)
• Gaseous atom, a largely fictional construct to aid determination of element properties. See this RD post

Arbitrary break 5

• Old style circuit symbols needed in lamp (electrical component)
• combline filter, comb-line filter
• system equivalence needs a makeover, and analogical models (also in need of a makeover) should either be clearly differentiated in scope or else the two should be merged. Some material from mechanical-electrical analogies could usefully be transferred. Also, the redlinks effort variable and flow variable should link to somewhere useful. Actually, flow variable is not a redlink, but even worse, it goes somewhere irrelevant to analogies.
• admittance needs the ungenaralization reversed, or else individual articles created
• magnetic tracking
• terminal needs some photographs of terminal types
• Fractal filter
• Electrical science, User:Spinningspark/Sandbox#Electrical science
• Siemens mercury unit, possible expansion from refs on talk page
• /Transient analysis (electrical circuits), another one that should have been written years ago
  • Note Transient (oscillation) already exists. See also the Transience disambiguation page.
• short circuit and open circuit. We really should have a network analysis description of this. Create redirect from short circuit (circuit theory) and open circuit (circuit theory) (or appropriate the current disambiguation page at open circuit)
• microwave component, redlink with one incoming link. Could do as list of microwave components
• Signal tower, should be an article, not a redirect to a US-centric railway term. File:8460Magalang Heliograph towers landmarks 16.jpg
• The Evolution of Character Codes, 1874-1968. List/comparison of telegraph codes? There is also a long discussion of commercial telegraph word codes in The Victorian Internet. Maybe just /Telegraph codes and incorporate a list in it.
• List of historical British telcos. See my note on the talk page. Needs de-BTing.
• /Frederick Charles Webb
• Quadruplex telegraph. Simplified diagram and description of operation needed as in this site. Fulton is marginal SPS but he did author this conference paper.
• Gauss and Weber telegraph, maybe Steinheil as well, and Schilling, although right now I am writing its description in his bio page Soemmering. Struck Schilling, doing as a separate article. Fahie is a good place to start for the rest. Hubbard (see Schilling article), p. 14 has an interesting comment on Steinheil. Garratt in the Schilling telegraph article is also a good source.
• Jacob Brett, the cockup with his Legion of Honour award [5] would make a great DYK.

Arbitrary break 6

• William Francis (editor), translator of the first English version of Ohm's seminal work and the Francis in Taylor and Francis obituary
• Thomas Dixon Lockwood VP American Institute of Electrical Engineers, see [6]
• Bilateral (circuit theory) (redlinked in Reciprocity (electrical networks)
• Earth mode communication. Mentioned on ultra low frequency. There was also a discussion somewhere about germans listening in to earth-return telegraphy in WWI. I don't think that's true, it was probably earth mode misremembered.
• Fullerphone, used to overcome espionage by earth loop induction.
• Outphasing. There is already Ampliphase but that is a trade name of an obsolete version. The article does not cover the modern resurgence of the idea.
• Royal Dockyard Battalion. Seems this should have an article. Some coverage in British Naval Swords and Swordmanship.
