Editing Wow! signal (section)

=== Bandwidth ===
The Wow! signal had a [[Bandwidth (signal processing)|bandwidth]] of less than {{val|10|u=kHz}}.  It is considered [[narrowband]] emission in the sense that its fractional bandwidth was relatively small (~1%).  However, the {{val|10|u=kHz}} bandwidth is not small compared to the bandwidth of some [[Maser#Astrophysical masers|astrophysical masers]] (~{{val|1|u=kHz}}) or to the frequency resolution of modern narrowband SETI searches (~{{val|1|u=Hz}}).<ref>{{Cite journal |last1=Margot |first1=Jean-Luc |last2=Pinchuk |first2=Pavlo |last3=Geil |first3=Robert |last4=Alexander |first4=Stephen |last5=Arora |first5=Sparsh |last6=Biswas |first6=Swagata |last7=Cebreros |first7=Jose |last8=Desai |first8=Sanjana Prabhu |last9=Duclos |first9=Benjamin |last10=Dunne |first10=Riley |last11=Lin Fu |first11=Kristy Kwan |last12=Goel |first12=Shashwat |last13=Gonzales |first13=Julia |last14=Gonzalez |first14=Alexander |last15=Jain |first15=Rishabh |display-authors=1 |date=6 January 2021 |title=A Search for Technosignatures around 31 Sun-like Stars with the Green Bank Telescope at 1.15–1.73 GHz |journal=[[The Astronomical Journal]] |volume=161 |issue=2 |pages=55 |arxiv=2011.05265 |bibcode=2021AJ....161...55M |doi=10.3847/1538-3881/abcc77 |s2cid=226290131 |doi-access=free |last16=Lam |first16=Adrian |last17=Lewis |first17=Briley |last18=Lewis |first18=Rebecca |last19=Li |first19=Grace |last20=MacDougall |first20=Mason |last21=Makarem |first21=Christopher |last22=Manan |first22=Ivan |last23=Molina |first23=Eden |last24=Nagib |first24=Caroline |last25=Neville |first25=Kyle |last26=O’Toole |first26=Connor |last27=Rockwell |first27=Valerie |last28=Rokushima |first28=Yoichiro |last29=Romanek |first29=Griffin |last30=Schmidgall |first30=Carlyn |last31=Seth |first31=Samar |last32=Shah |first32=Rehan |last33=Shimane |first33=Yuri |last34=Singhal |first34=Myank |last35=Tokadjian |first35=Armen |last36=Villafana |first36=Lizvette |last37=Wang |first37=Zhixian |last38=Yun |first38=In |last39=Zhu |first39=Lujia |last40=Lynch |first40=Ryan S.}}</ref> The Big Ear telescope was equipped with a receiver capable of measuring fifty {{val|10|u=kHz}}-wide channels.
