        I recently moved and so I had to change  to  a  different
cable  TV  service.   I  thought, "No problem, I have cable-ready
TV's and VCR."  Well, they hooked me and I hit the "cable" switch
on  all  my equipment.  As it turns out, I do have a problem.  My
TV's and VCR are all  112  channel  capability,  but   it's   not
enough.  The cable service offers the standard 2-13 VHF Lo and Hi
plus cable channels 14 - 53.  My TV's and VCR get up to about  42
then  show  either  snow or channel 42 on the remaining stations.
My roommate has a converter (his TV is not  cable ready)  and  he
picks  them  all  up.   The neighbor has a 130 channel capability
set, and he receives them all fine.

        I didn't want to  get  a  converter  for  each  piece  of
equipment,  I'd  loose  the  use  of my remotes and being able to
record more then one channel while I was away.  So I  decided  to
invest  in  a RADIO SHACK cable block converter.  Before I bought
it I knew I was in for a project, it only moves channels 2-42  to
the UHF band. Channel 42 ends up on 83 UHF, it's what I have now.
Well, I cracked it open  and  decided  to  lower  the  oscillator
frequency.   I changed a coil and adjusted the trimmer cap.  This
moved things enough so I could get the missing 10 or so  channels
on  stations  72-82  UHF.   I  really  don't  care  about getting
everything moved onto UHF, I only want a  means  to  receive  the
missing  10  channels.   My problem now is these last 10 channels
are fuzzy.  Either the input has a trap for these higher channels
or  I'm  getting  harmonic  interference  from  the oscillator or
something.  I've adjusted the oscillator  around  but  no  matter
where  I  put  the  missing 10 channels, the upper 8 of these are
fuzzy, the lower 2 are usually OK.

        Has anyone attempted  this  before,  have  any  ideas  to
bounce  around,  know  of  a  block converter that will do what I
want, or need something to do and would like for  me  to  send  a
schematic  as  an exercise ?  No ?  Can't blame you, I don't know
what to do either 8-) !  If nothing else, I'll try to  live  with
the fuzziness.  Anyone else have this problem ?
