The device described in the section HF and VHF is a transmission or indicating wavemeter. An absorption wavemeter has no diode-detector or galvanometer; it's simply a tunable resonant cavity (or circuit) which is coupled to a feed line, so that it leeches energy out of the line at the resonant frequency. This creates a notch at a known and adjustable frequency in the spectrum of the signal passing down the line. I suppose the arrangement described could be interpreted as an absorption wavemeter plus a detector. Given that there appears to be no transmission wavemeter page at present, why not rename this page to wavemeter? --catslash (talk) 20:33, 5 October 2009 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2009-10-05T20:33:00.000Z","author":"Catslash","type":"comment","level":1,"id":"c-Catslash-2009-10-05T20:33:00.000Z-Confusion_with_transmission_wavemeter","replies":[]}}-->

"the resonant circuit absorbs energy, which is indicated by a dip on a meter." Isn't the indication a peak on the meter of the wavemeter? The resonant circuit of the wavemeter absorbs energy which is indicated/detected on the meter as an upward deflection. Confusion might exist because the external resonant circuit to which the wavemeter is coupled might give a dip to indicate the loss off energy, which is more similar to how a Grid Dip Oscillator operates.--MikeCrystal (talk) 08:19, 27 December 2015 (UTC) Mike Crystal[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"2015-12-27T08:19:00.000Z","author":"MikeCrystal","type":"comment","level":1,"id":"c-MikeCrystal-2015-12-27T08:19:00.000Z-Dip_or_Peak??","replies":["c-Catslash-2015-12-27T18:07:00.000Z-MikeCrystal-2015-12-27T08:19:00.000Z"]}}-->

The article confuses absorption wavemeters and indicating wavemeters - see my post at the top of this page. Baden Fuller (Microwaves, 1st ed. 1969) says:

The absorption wavemeter acts by absorbing a small amount of the microwave power at its resonant frequency causing a small dip in the indicated power in the waveguide system. The transmission or indicating wavemeter also absorbs a small amount of power at its resonant frequency, but couples this power to an output waveguide or detector. When the wavemeter is on tune, there is an indicated output from it but at all other frequencies there is no output.
