Quadraphonic Radio Discography
6-14-2014 Version 1.9

   This list was created to document the quadraphonic Radio Broadcast
that took place from 1969 to the late '70's.
A few Bootleg records appeared over the years made from these 
You can always count on a tape deck rolling somewhere and this list 
might be most useful to tape traders that are willing to go to any 
length to get a recording of something they crave.
   Any information you might be able to pass on is appreciated,
Rolling Stone Magazine's from the era are a great source for this info
since many quad radio broadcasts were advertised if the radio program
had national distribution.

       During the quadraphonic era, there were hopes that radio broadcasts
    someday would be all multi-channel.  
    To broadcast Quadraphonic was difficult and never actually came to a
    solution. One attempt to broadcast in quad was by using one radio 
    station to broadcast the front channels while another broadcast the 
    rear. In order to receive these "Discrete" broadcasts, a second stereo
    FM receiver was needed. This proved to be problematic since
    owning two stereo receivers was not a reality for most.
    The other method was to matrix the 4 channels to 2 and then decode
    the 2 channels back to 4 on your home receiver.
    There were suggestions to broadcast the extra channels by multiplexing
    them on a second subcarrier at 76 kHz. These designs were made by Zenith
    Corporation, General Electric, RCA and Dorren Quadracast Systems.
    There was never an agreement between the FCC and the EBU how to 
    broadcast quadraphonic sound, but here in the U.S. The
    National Quadraphonic Radio Committee (NQRC) recommended 
    the Quadracast system from Lou Dorren and was adopted by the FCC in
    1983. Brad Miller was the only representative of the industry who wanted
    a discrete system, and CBS even proposed a USQ system that was 
    compatible with Matrix SQ, yet had a discrete sub-carrier for optimal
    performance.  They even developed a fully discrete Matrix system, but it
    never was really developed, although it was patented.
    The BBC was designing their H-matrix at the same time and they regarded
    it at that time as Quadraphonic.
    Live rock concerts were broadcast in matrixed Quadraphonic formats on
    syndicated shows like the "King Biscuit Flower Hour".

Broadcast on WXRT GENTLE GIANT - King Biscuit Flower Hour 9/28/75 (SQ) Golders Green Hippodrome, London, January 5th 1978 (MH) {The above concert has been issued on CD as "BBC Radio 1 In Concert" Windsong, WIN CD 066 (England) ('94) & and as part of a two-disc set, "Out Of The Fire" Hux Records, HUX008 (England) ('98). The latter and this bonus CD apparently contain a previously missing track. It was also issued on video as a DVD titled "Sight and Sound in Concert" Alucard UK B000EQ5VCW. The audio from the stereo broadcast is used for the DVD as well as the CD. Pete Drummond's [edited for transmission] on-stage intro to the concert ("In Concert" #169, which was broadcast January 21, 1978) apparently stated: "Hello and welcome to Radio 1's [Sight and Sound] In Concert which you can hear on 247 metres on the Medium wave, in stereo on the Radio 2 VHF network, between 88 and 91 MegaHertz, and, [of course, you can see it on BBC2 in colour. And, as a special first for tonight's show, we're broadcasting in Quadraphonic so, those of you that have got a BBC H-matrix quadraphonic decoder, well.. you're very lucky and if you've got four ears you're luckier still! Richard Elen provided a review: On decoding it via our UHJ decode process, it does indeed appear to be an Ambisonic recording (with the exception of the last two tracks, which are of dubious audio quality, come from OGWT in 1974, and are in mono). Audience appears to come largely from the rear while the band occupies a wide front stage and some items pop out or occasionally occupy locations further round. Non-LF aspects of the soundfield appear to be rotated somewhat, which does indeed suggest Matrix H, and the surround decode is definitely worth the effort. Goodness knows what setup was used to record this} GRATEFUL DEAD - * Winterland, S.F., CA. 10/4/70 – another KQED-TV broadcast, with a live quadraphonic simulcast on KQED and KSAN. {The video has never circulated; the KSAN FM broadcast is the source for our tapes (and was also the source for one of the most famous early Dead bootlegs in 1971.} {Any tapes that endure are almost certainly from one feed or the other, and thus the true effect of the mix can never be recaptured.} * KQED Studios, August 30, 1970, San Francisco, CA.

Fortunately the 16 & 24 track reels that were used to mix the quad encoded tapes were stored in a different facility and he was able to use those and remix them for the CD's. Therefore only the original 1/2 track 2 channel SQ reels sent to the radio stations and copies made by folks on their home recorders contain the quad mix. CD's issued later are not SQ encoded. A 60 minute show was comprised of 53 minutes of the program and advertisements from the shows sponsors 7 minutes of local advertising.

Billboard 9-2-72 CALEBRATION July 11, 1970 from midnight to 1:30 a.m., history's first quadriphonic TV simulcast was aired to more than one million viewer/listeners throughout the San Francisco Bay Area. KPIX (Channel 5), a Westinghouse owned television station, aired a videotaped rock concert while simultaneously the audio portion was being broadcast in four-track stereo from two local FM radio stations. KPIX teamed with stereo radio stations K101-FM and KCBS-FM to present Calebration, a 90-minute presentation featuring the Chambers Brothers, Boz Scaggs and Linda Ronstadt. The stereo rock concert was presented in color to a light show. It marked the first time television has offered viewer/listeners a video presentation with 4-channel sound. DB Magazine OCTOBER 1970 & BROADCASTING, July 6, 1970 The program will be seen on the four other Westinghouse Broadcasting television stations in late December and early January. The 90 minute video tape will be distributed along with a four track stereo audio tape to WSZ-TV Boston, KYW-TV Philadelphia, WJZ-TV Baltimore, and KDKA -TV Pittsburgh. Ampex Corp. will supply the 16-track audio tape machines in each market so the program can be aired in quadraphonic sound. Radio affiliations for the broadcast have not been announced. BROADCASTING, Nov. 30, 1970 & BROADCASTING, Dec. 14, 1970 The basic recording was made in four track. The instrumentalists were recorded in four track using all four tracks. Vocal and other down -stage performances were picked up on our "front line" of mics and unequally panned between front left and right. We had the option of panning the vocal content to the rear speakers. This was done on occasion for effect, but at no time could we put all vocal content on channels 1 and 2 or 3 and 4. To say it another way, each of the participating FM stereo stations had to receive vocal information on at least one channel at all times. In addition a mono mix had to be obtained for those who viewed the show without quad. The mono mix was done by combining the four channel quad. Recording in simultaneous quad and mono made it necessary to give very careful handling to the amount of in phase panned signal content. At no time did the in phase panned signal appear on all 4 speakers a la "joy- stick" or otherwise. We used four non directional mics at optimum points on the stage to enhance the quad effect. One of these four mics was used on each of the four quad tracks to give added support to the ambient room sound. Don Geis Director of Recording McCune Studios San Francisco, Calif. DB December 1970 April 3-1971 KPIX TV "Calebration" show with Jerry Garcia, Joy of Cooking, Hugh Masekela and Pot Liquor Broadcast live on TV and 2 radio stations (KCBS & KIOI) to coincide with the bay area Hi-Fi show in Palo Alto. Prerecorded and shown about 1 month later. BROADCASTING, MAY 8, 1971
    Broadcast That Are NOT Quad EMERSON, LAKE & PALMER - California Jam - Ontario Motor Speedway, CA. '73 {The bootleg album of ELP-California Jam. Trademark of Quality/Highway Life F1-113 indicates that it will provide quadraphonic sound when played through a QS decoder. The series "ABC In Concert" that broadcast 4 episodes of the California Jam performances did simulcast in stereo on FM radio stations but none where done in quad. KLOS in L.A. might have synthesized the stereo source to quad and announced it as quad} CAT STEVENS - * "Moon and Star" ABC In concert Simulcast, Aquarius Theater, Los Angeles November 1973 broadcast on KLOS {At the end of the simulcast the KLOS DJ announces the show was broadcast in quad. The concert was simulcast in stereo in 7 markets (LA, Chicago, NYC, SF, Houston, Pittsburgh and Detroit). It was also advertised in TV Guide and Billboard as a stereo simulcast was a big deal event at the time. None of the advertising mentions quad that would be an ever bigger deal. Billboard reported on Nov. 3, 1973 that during quad broadcast tryouts that "KLOS used a QS encoder and ran all their programming through the encoder". It appears that the stereo simulcast was synthesized for quad and not actually from a four channel mix} JETHRO TULL - 11-16-1979 Santa Monica, CA. KMET broadcast
    1969 From 1969 until about 73 or 74, the Saturday night Boston Symphony Orch. concerts were in Quad. WGBH FM and WCRB-FM splitting the 4 channels of audio. At first, it was one doing the 2 left channels and the other the 2 right channels. Later it was changed to one 2 doing the 2 front channels ,left and right; and the other 2 rear channels ,left and right. Beginning in September 25 1969, WCRB radio in Boston began experimenting with quadraphony, collaborating with WGBH to present a series of Boston Symphony concerts live in discrete quadraphonic sound, two channels being transmitted via WGBH and the other two on WCRB. These quadraphonic BSO broadcasts continued through the 1973 season, and WCRB broadcast some of its recorded music using the SQ quadrophonic system for several years afterwards. Another stereo test San Francisco high fidelity buffs had a special treat last Thursday night (Dec. 4, 1969), when two FM stereo stations broadcast four channel stereo. It was estimated that 100,000 people heard the program, transmitted from 8 p.m. to 10 p.m. on Dec. 4 by KPEN-FM and KRON-FM. Four -channel stereo uses two stations to broadcast the music. Listeners are required to have two receivers and four speakers. Two of the four speakers, placed at the rear of a living room, perform as reverberation sources. A similar broadcast took place recently in Boston. BROADCASTING, Dec. 8, 1969 In the later part of 1969, San Francisco's KRON began its first four channel broadcasts. KRON broadcasted the front two channels and station KIOI broadcast the rear two channels. For their first Quadraphonic broadcast, Ampex tape corporation provided four channel Reel to Reel tapes with music from various record labels. {Actually the 1969 Discrete Quad FM Broadcasts were done with K-101 (KIOI) and several partner stations including one in the Sacramento area that also had the 101 position on the FM dial. It involved Lou Dorren and his "Quadracast" FM technology. Also, K-101 broadcast the Front Channels as I recall - not the rear channels. During those "experimental" 4 Channel Discrete Quad demo broadcasts, K-101 owner Jim Gabbert had some really cool Surround Sound source material including a 4 Channel mix of the "Paint Your Wagon" Soundtrack, Sound Effects and Mystic Moods albums produced and mixed by Quad pioneer Brad Miller and several more only for the demo Surround tapes. Details proved by Brian Moura} WGAR-FM & WCLV-FM in Cleveland Ohio teamed up on April 16, 1969 to broadcast a Cleveland Orchestra concert in Boston in a onetime simulcast. * Four channel broadcast (utilizing two stereo FM stations) were done in Tanglewood, Mass. with Acoustic Research, Inc. being one of the sponsors. AR set up a four channel system in its Grand Central Station exhibit room for all to hear. Reports are that CBS is producing the demo tapes. 1970 Demonstrations of four -channel stereo broadcasting, known as quadraphonic stereo and requiring two FM stations to make it function, will be aired during the National Association of Broadcasters convention in Chicago on April 7, it was announced last week by WEXI (FM) Arlington Heights, Ill., and WMAQ FM Chicago. The independent outlet and the NBC -owned station are cooperating in the experiment under special FCC authorization. Half hour demonstration programs are planned using special four channel tapes being supplied by major record firms. A listener uses two FM sets to hear quadraphonic. BROADCASTING, April 6, 1970 During the past decade commercial sound reproduction has progressed from monophonic to two-channel stereophonic reproduction. Since the pilot tone system of broadcasting in use today is limited to two channels, a new but fully compatible four-channel system was developed. This "Dorren Quadraplex System" was designed from the start to meet the following conditions: A full compatibility with all existing equipment; A unimpaired directionality and channel separation; A reproduction of the frequency range 50 to 15,000 Hz in all channels; A minimum distortion and cross-talk between channels; A minimum signal-to-noise ratio impairment, no additional RF spectrum requirements. Experimental use of this system for broadcasting began at radio station KIOI in San Francisco in December 1970, with a Station Temporary Authorization from the Federal Communications Commission. Additional broadcasts were done over another major station, CHFI in Toronto, Canada. This test was supervised by the Department of Communications and the Canadian Radio and Television Commission. It was found that "Compatibility was evident in all cases". Additional testing and use was expected in Japan in the near future. The system had shown itself to offer performance far better than the minimum FCC standards. 1971 In 1971 Minneapolis radio WLOL-FM conducted Minnesota's first discrete 4-channel broadcasts. By using WLOL for the front stereo pair, and transmitting the rear stereo pair thru phone lines to Minnesota's educational radio KSJN. The second attempt at discrete 4-channel broadcasting eliminated the phone lines. The front stereo pair was transmitted on WLOL-FM and the rear pair was broadcasted by KEEY-FM. Mark Durenberger, a DJ at WLOL at the time of these broadcast shares his thoughts on those days 1971 October: KTUH presented the first "quadrophonic sound" radio program in Hawaii. If electronically equipped, listeners will receive four separate signals through four different speakers. The first quad broadcast in Houston Texas took place on May 9, 1971 by using two radio stations, KAUM and KPFT playing records by Steam, Enoch Light, Buffy Saint Marie and natural sounds such as thunder * KZAP-FM Sacramento, CA. broadcast the first 3-channel radio in 1971, teaming up with KERS-FM, which broadcast the back channel. The station first broadcast a matrix program in 1971 and is now using the SQ CBS system featuring a Sony matrix encoder. * Electro-Voice is producing a professional model stereo encoder, model 7445. The unit makes it possible to broadcast four -channel sound by FM stereo stations by encoding any original four channel program into a two channel signal * KIOI San Francisco, CA. experimented with the Dorren Quadraplex System for two months earlier this year. In a petition last week, asking the commission to amend its rules to permit quadrasonic transmission on FM bandwidths, claimed that the four channel system is at least equally efficient as its multiplex predecessor, with the added advantage of offering a stereo signal transmitted and received from four directions, as opposed to multiplex's two -directional capability. It does this essentially by sending out four signals: two side band pairs, each with a bandwidth of 91 khz, for a total radius in the spectrum of 182 khz. (Multiplex systems use one sideband pair) said that its field tests of the Dorren system proved that quadraplex "in no way" degrades existing stereo standards, as do experimental four channel systems now used by some FM's that have a matrix type of encoding process. Another advantage of the four channel system, is that it can be handled through the facilities of one FM station. In addition, on air tests have proved quadraplex's performance to be equal to existing two channel multiplex systems. Present stereo or monaural radio receivers, "show no degradation or loss of reception capability in picking up a quadraplex signal. The system can be accommodated in present FM channel assignments. It uses a channel separation of 45 db. 1972 WFMT, Chicago did a four-channel broadcast in September 1972 of opening night at the Chicago Lyric Opera, a production of "Semiramide" by Rossini. They received a special 1973 Ohio State Award for its live, four-channel broadcast In 1972 the BBC made Quadraphonic recordings at the 50th Anniversary Promenade Concert at the Royal Albert Hall. In 1974 The BBC demonstrated Quadraphony at the International Electronics Expo. 1977 - Year of experimental quadrophonic broadcasts using Research Department's 2 channel matrix. In the Middle of the night, produced and hosted by Andrew Marshall was Canada’s 1st quadraphonic concert on CBC-FM in 1972. The program featured classical music in the SQ format, both live performances and recorded discs. The Dutch state radio network (NOS) in Amsterdam in conjunction with Radio Nederland Wereldomreop broadcasted its first quadraphonic program in August 1972 featuring the Radio Chamber Orchestra from a church in Utrecht * WREK and WGKA-FM have broadcast the first discrete quadrophonic broadcast in the Atlanta area. This was after many months of searching for an adequate source of discrete quad material. The large majority of the programming came from the RCA quad eight track cartridges. Four announcers were used, two from each station. Voice tracks for the spots were played from cartridge over the front channels (WGKA-FM) only. The material that was not from the eight track cartridges consisted mainly of four-channel pre-recorded open reel tapes (primarily Project 111) and studio dubs (such as Gandharva from Orban Studios, Menlo Park, Calif.). An electronic piece by Dick Robinson of the Atlanta Symphony was also included. 1973 * The King Biscuit Flower Hour broadcasted its first Quadraphonic show on April 29, 1973 with the performances by Edger Winter & Richi Havens in the SQ Matrix format. The first stereo performance was on February 18, 1973 with performances by Mahavishnu Orchestra, Blood, Sweat and Tears & Bruce Springsteen and syndicated to about 50 stations. San Francisco classical music station KKHI broadcast the San Francisco Opera in QS matrix encoded quadraphonic format during the 1970s. 1974 Back in 1974 and 1975 there was a short-lived radio station WQIV in New York City. One of their "innovations" (gimmicks?) was full time QS-quad broadcasting. The quad format was even related to their call -letters -they called themselves "cue four (Q-4)." They were a commercial rock station with an emphasis on progressive rock. They broadcast live concerts, the earliest syndicated Rock Around the World shows, whole albums, and other things unusual at the time on commercial radio. The station was short-lived since it was converted from a classical format (WNCN) whose loyal listeners put so much pressure on the owners that they had to bring back the classical format. Live Quad QS encoded broadcasts took place from "Electric Lady" Studios in N.Y.C. A quad fan had some interesting comments about the shows WCLV, Cleveland’s fine arts station produced SQ Quadraphonic broadcasts for national distribution of the Severance Hall concerts of the Cleveland Orchestra in 1974 & 1975. The Rose Parade was broadcast in Quad (format unknown) on KMET-FM at 94.7 in 1974 as a simulcast with local TV station channel 11. General manager L. David Moorehead says four engineers will be assigned to the project, hosted by the zany Credibility Gap. Mikes will be situated so you can hear the marching band from left to right, and you’ll be able to hear them turn the corner and hear crowd noises in the back of you. 1975 1976 KIOI and KBFG in San Francisco on July 24, 1976 broadcasted 1.5 hours of a variety of songs including Doobies, Jeff Airplane, Creedence Clearwater Revival, The Guess Who, "Open Road" by Donovan (Rare) and the Paint your Wagon opening. 1977 During 1977, The British Broadcasting Company (BBC) conducted quadraphonic broadcast using the BBC's research departments 2 channel matrix. The matrix format was known as Matrix HJ at that time, the predecessor to the Ambisonic UHJ format. The 1977 season of the Filarmonica de las Americas in Mexico City was broadcast (and recorded for delayed broadcasting) in the SQ quadraphonic system. A "Ghent microphone system" was used as a principal microphone, with accent microphones added as required. Placed in front of the orchestra, the Ghent microphone provided a conventional single-point stereo pickup with the house ambience encoded in the surround mode. A unique method of surround-sound orchestra pickup was devised by placing the microphone in the middle of the orchestra, facing the audience but favoring the strings, and reversing the encoded output channels left for right in order to preserve the correct left-right instrumental placement for the listener. Eesti Radio is a national public radio organization in the Republic of Estonia. March 13, 1977 the first quadraphonic program was aired from Tallinn by a special FM transmitter. These experimental programs lasted till 1980. 1978 1979
    1980's The fate of FM quadraphonic still hasn't been determined, and soonest comission is expected to address it now is first quarter of 1983, according to official in Broadcast Bureau. Commission rulemaking sought comment on whether to adopt specific standards for systems or leave that up to marketplace. All indications are that FCC is leaning toward marketplace. The government run radio stations in Switzerland conducted discrete Quadraphonic broadcasts during the 1980's. Classical Music was broadcasted via DRS1 (sending the front channels) and DRS2 (sending the rear channels). Pop music and jazz were broadcasted via DRS3 (front channels) and DRS2 (sending the rear channels). Apparently these were going on as late as the 1980's. Poet Chris Mann created a four channel work entitled Quadraphonic Cocktail, which was broadcast simultaneously on both ABC’s Metropolitan & National and Fine Music networks on Australia Day, January 26th 1986. Mann invited the audience to “mix your own audio adventure” using multiple radio receivers. {Not sure how many people would have 4 radio receivers in close proximity or possibly 3 - "Fine Music" is the old name for Classic FM which is stereo, but ABC National and ABC Local (= Metropolitan) are mono FM. Neb-Maat-Re} 2000's KCJJ 1630 AM Stereo in Iowa City, Iowa broadcasted shows in Dolby Surround Pro Logic II in 2010 & 2011 using discrete quadraphonic tapes during the Robb Spewak show.
