1. ERIC SIEGEL S VIDEO REPORT A _ Half Inch World Video Standard The European Scene Electronic Correction Videotape Publishing Since the very first issue of Radical Software have been writing about video standards In issue number 3 I advised everyone to adopt the American 525 line stan dard This seemed rational for Americans but Europe ans may have thought that I had some ulterior motive for pushing American equipment in Europe The only motive I had was compatibility Now however I have devised a way to modify Sony type one standard equipment so that it can also be used in Europe In all half inch battery operated portable VTR s there is a servo locked head motor drum motor American machines in the head drum servo are tuned to free run at a 60 cycle alternate current driving frequency The motor hovers at a harmonic multiple of the vertical scan rate which is the same as 60 cycle house main current In order to make an American standard recorder work on the European standard you readjust the driving oscillator free running frequency to 50 cycles which is the European house main current With this simple ad justment you can have a world standard half inch vi deotape recorder with an American VTR and further more all 625 line European tapes will be compatible with 525 line standard AV machines which change the driving oscillator from 50 to 60 cycles If you have a Sony AV3400 VTR the addition of two 4 7 k ohm re2. i P_circyi inside of this case microphone inside of this screen vidicon coil assembly TARGET VOLTAGE R248 v VIDICON G H BOARD R325 263 H BOARDO D303 BEAM t 100V INPUT L357 _ D BIARD 966 CLEANING PASE INPUT 114 A RADICAL SOFTWARE STATE OF THE ART REPORT a206 207 0208 9209 Pan SVIEC aP CLEARER 6TH VIDED MP TEWOED Aa oe van P ED a D aye hoa apar SES en LOW LIGHT LEVEL EIAJ VTR GBC CCTV Corp announces the total darkness Porta Pack camera VTR system The camera has a 2 3 Tivicon developed for GBC by Texas Instruments capable of producing a clear picture with only 1 1000 of a foot candle faceplate illumination It is also sensitive to infra red and in cludes a zoom lens built in micro phone and electronic viewfinder The VTR is Sony s VideoRover II with stop action Unit is expected to have wide application to the security sur veillance police fields Total weight including battery 18 Ibs Delivery immediate Adjustment Screws Circle 28 on reader service card 2 0a 349 Jesu plate ph etd raw 7 2947 34402 2 06 922 7 062 383 C ot elg cass P Dugd 2044815 02 lers moun B gt 2 042 368 SOG reset Cor ugated washer lens mount 115

Lexington Avenue New York City 684 3136 where we know we can get good prices honest information on delivery and reasonably reliable back up service But be cause the owner Jack Goldman does not yet have a Sony dealer franchise he does have a Sony service franchise he must get his supplies from other dealers and thus can not always fill an order If this is the case we then call C T Lui at C T L Elec tronics 86 West Broadway New York City 233 0754 who because he is a dealer often has stock But while Lui s prices are often the lowest possible he has sometimes reneged on a deal after it was made Moreover he some times tries to sell new equipment that has been opened 110 While Lui maintains that this is just to get a spare accesso ry if you are paying fair price than it is not unreasonable to ask for sealed equipment Lui s service which was terri ble in the past has greatly improved under the guidance of John Brumage Moreover Lui has pioneered in equip ment modifications and is usually well informed about new possibilities So check in there and compare prices before you buy The third outfit with which we deal is Harvey Radio Pro A V Division 444 Madison Avenue New York City 832 8675 which when it has stock which is usually main tains discount prices as low as anyone in town Harvey Radio is also a franchised Sony dealer Also a good place to check before you buy Those of you are are
