                     TV INTERFACE FOR R7000

                            John Biro

     I just got the video interface for the R7000, and to my
     surprise it is not an internal option.  It bolts to the
     side of the radio (right side were the rubber feet  use
     to  mount).   It  is  about  1  inch wide, and the same
     height and length as  the  R7000,  and  in  a  matching
     cabinet.

     TV video is taken off the 10.7 MHz IF output jack, this
     presents  a  problem  if  you  are  using it for a Band
     Scope.  It also "steals" the power from the  IF  output
     (the center pin of the IF out carries 12VDC so be care-
     ful not to short it out).

     The interface provides RCA type jacks  for  both  Video
     out  and  Audio  out.  The Video is standard levels and
     the Audio is low level output for input  to  a  typical
     audio  amp (it can not drive a speaker directly).  I am
     not sure why the audio output is there as you can moni-
     tor the audio on the R7000, looking at the circuit they
     do have a sideband filter circuit so I would assume the
     audio  is  cleaner  but  I have not tried it and do not
     have any problem with the R7000  audio  receiving  WBFM
     from the TV stations.

     Results: The TV-R7000 works OK, but I  am  just  disap-
     pointed  in  the fact that it does not mount internally
     in the R7000.  This could also help in its  high  price
     tag  of  $119.  I had a Yaesu FRG9600 with video option
     (only about $30), and it worked about  the  same.   The
     picture  quality  is  good,  and it is very stable.  My
     antenna is vertically polarized, so I am working  cros-
     sed  polarized  for  TV  stations  but  still  get good
     results, strangely better on UHF  then  VHF  freq.   In
     fact,  I  get  UHF  on  this set up better then my late
     model TV upstairs.
