Section  VI 
SITE  ACCURACY  PROGRAM 
18.  (U)  GENERAL.  An  aggressive  site  accuracy  program  is  essential  to  the 
efficient  operation  of  any  OF  site.  It  Is  also  essential  that  the  equipment 
be  accurately  aligned  and  in  proper  working  order.  To  accomplish  this  the 
OF  site  supervisor  will  - 
UNCLASSIFIED
UNCLASSIFIED 
a.  Insure  all  OF  equipment  Is*  checked  dally  In  accordance  with 
applicable  technical  publications.  Any  equipment  falling  to  pass  service- 
ability  criteria  will  be  reported  Immediately  to  maintenance  for  repair  or 
replacement. 
b.  Make  dally  system  alignment  checks. 
c.  Require  periodic  Check  Searing  Observations  throughout  the  24-hour 
operations  day. 
19.  (U)  SYSTEM  ALIGNMENT  CHECKS,  a.  A  predetermined  target  transmitter 
location  will  be  established.  The  exact  location  will  be  marked  by  a  painted 
stake  or  a  small  wooden  platform  so  the  target  transmitter  can  be  positioned 
In  the  same  exact  location  twry  day.  The  location  must  be  a  known  azimuth 
(not  necessarily  True  North);  and  If  at  all  possible.  It  should  be  600  feet 
from  the  antenna  array,  or  at  least  a  minimum  distance  of  300  feet. 
b.  The  system  alignment  check  will  be  performed  at  the  same  time  each 
day,  preferably  at  the  start  of  the  day  shift.  The  following  steps  will  be 
followed: 
(1)  Find  a  clear  frequency  between  two  and  four  MCS  and  tune  the  T-279/UR 
Target  Transmitter  to  the  frequency. 
(2)  Place  the  target  transmitter  lit  front  of  the  predetermined  calibration 
point  1n  line  with  the  known  azimuth  making  sure  the  T-279  antenna  Is 
fully  extended  and  no  one  Is  within  20  feet  of  the  transmitter  to  preclude 
error  caused  by  reradlatlon.      '- 
(3)  Observe  the  bearing  on  the  azimuth  indicator  positions  to  see  If  an 
accurate  bearing  Is  recorded.  (NOTE:  A  small  dot  should  be  painted  on  the 
alidade  assemblies  at  the  correct  azimuth  to  be  used  for  comparing  the 
bearing  taken  during  dally  system  alignment  check.) 
(4)  If  the  bearing  displayed  differs  from  the  known  azimuth  of  the  target 
transmitter,  the  system  must  be  aligned  to  the  correct  azimuth.  (Alignment' 
procedures  will  vary  according  to  the  OF  system  In  use.) 
(5)  After  the  system  alignment  check  has  been  completed,  the  target 
transmitter  will  be  turned  off  and  returned  to  storage.  The  transmitter  will 
not  be  left  at  the  calibration  point  after  the  alignment  checks  have  been 
completed. 
20.  (U)  CHECK  BEARING  OBSERVATION.  Hhen  the  OF  site  supervisor  Is  satisfied 
that  all  OF  equipment  is  aligned  and  working  properly,  check  bearings  will  be 
obtained  from  each  OF  position.  Only  check  targets  of  known  locations, 
authorized  by  the  NCS  or  higher  authority  for  the  specific  purpose  of 
obtaining  bearings  for  accuracy  studies,  will  be  used.  The  site  supervisor 
must  Impress  upon  the  OF  operator  the  Importance  of  recording  accurately  the 
UNCLASSIFIED
USA  INSCOM  Reg  105-11 
bearings  they  observe  and  not  being  Influenced  by  the  known  bearing.  Check 
bearings  should  be  taken  and  recorded  throughout  each  24-hour  operational 
day  as  a  continuing  check  on  system  alignment  and  noticeable  changes  In 
atmospheric  conditions.  Continuing  errors  1n  known  check  bearing  targets 
may  require  an  additional  DF  equipment  alignment. 
Section  VII 
MAINTENANCE 
21.  (U)  GENERAL.  Outdoor  maintenance  requirements  will  differ  with  climatic 
conditions;  however,  regardless  of  conditions,  maintenance  Is  a  continual  and 
essential  function  of  DF  operations  and  Its  sustained  accuracy.  The  DF  site 
supervisor  must  conduct  a  vigorous  maintenance  program  to  insure  optimum 
equipment  operation  at  all  times  and  1n  all  weather  conditions. 
22.  (U)  PREVENTIVE  MAINTENANCE.  Dally,  weekly,  and  monthly  PM  must  be 
carried  out  1n  accordance  with  local  maintenance  policy  as  prescribed  by 
command  directives  and  current  regulations. 
a.  DA  Form  2404  (Equipment  Inspection  and  Maintenance  Worksheet)  will 
be  used  for  recording  dally  inspections  and  services,  periodic  preventive 
services,  and  Inspection  of  equipment  by  maintenance.  When  used  by  mainten- 
ance personnel  for  recording  periodic  PM  services,  all  deficiencies  found 
to  exist  at  the  time  of  Inspection  wllrbe  recorded.  When  used  by  the  equip- 
ment operator  during  operational  Inspections  and  services,  only  those 
deficiencies  that  cannot  be  corrected  by  the  operator  will  be  recorded.  DA 
Form  2404  used  for  recording  the  operator's,  dally  Inspection  will  be 
furnished  the  maintenance  supervisor  for  any  other  action. 
b.  Close  supervision  will  be  qlven  to  all  phases  of  PM.  Special 
attention  should  be  given  to  the  following  details: 
(1)  Cleanliness  not  only  enhances  the  appearance  of  the  DF  site,  but 
more  Importantly,  1t  1s  essential  In  preventing  dirt  and  grime  from  getting 
Into  equipment,  causing  undue  wear  and  tear  and  eventual  equipment  breakdown. 
The  floor  of  the  operation  shelter  should  be  damp-mopped  as  frequently  as 
necessary  to  keep  it  dirt  and  dust  free.  The  tops  of  the  electrical  cabinets 
will  be  dusted  and  kept  clear  of  all  materials  so  that  excess  heat  generated 
by  the  equipment  will  pass  through  the  ventilating  holes  as  1t  was  designed 
to  do  and  interior  components  remain  clean. 
(2)  Overheating  1s  the  frequent  cause  of  breakdown.  To  help  prevent 
these  breakdowns,  observe  the  following: 
(a)  Electrical  equipment  Inside  the  cabinets  will  be  Inspected  dally  and 
vacuumed  regularly. 
(b)  Keep  all  filter  screens  free  of  dirt  and  dust  by  frequeit  cleaning. 
The  screens  will  be  checked  as  part  of  the  dally  PM  check  list  <md  cleaned 
as  required.

SECURITY 
27.  (U)  GENERAL.  All  facets  of  OF  operations  are  of  the  utmost  Importance; 
however,  no  function  can  be  said  to  be  more  Important  than  security.  A 
breach  1n  security  not  only  endangers  the  physical  security  of  the  OF  site, 
but  endangers  the  OF  mission  and  damages  the  security  of  the  Nation.  A  more 
than  common  knowledge  of  current  security  directives  and  regulations  Is 
strongly  encouraged  particularly  1n  regards  to  the  local  situation.

visitors  to  the  site  denoting  name,  rank,  SSAN,  position,  purpose  of  visit, 
signature,  time  in  and  time  out.  Each  entry  will  be  initialed  by  the  site 
supervisor  at  the  conclusion  of  each  visit. 
b.  Close  control  of  crypto' material  will  be  kept  at  all  times.  A 
crypto  material  checklist  will  be  kept  listing  all  crypto  material.  An 
inventory  will  be  performed  and  the  DA  Form  2653  (COMSEC  Account  -  Dally 
Shift  Inventory)  will  be  signed  by  the  senior  operator  of  the  on-coming 
trick  prior  to  relieving  the  trick  on  duty.  Any  discrepancies  which  arise 
will  be  brought  to  the  Immediate  attention  of  the  DF  site  supervisor  (regard- 
less of  hour)  for  appropriate  action.  In  addition  to  the  inventories  made 
by  each  on-coming  trick,  the  site  supervisor  will  also  make  a  physical  crypto 
material  check,  a  minimum  of  once  a  week  to  Insure  records  are  being  properly 
maintained  and  the  security  containers  locking  device  is  1n  proper  working 
order.  Controlled  document  registers  and  document  destruction  certificates 
will  be  kept  to  show  the  proper  disposition  of  classified  documents  at  all 
times.  The  site  supervisor  must  become  familiar  with  all  logging,  handling, 
and  collateral  classified  documents/materials. 
29.  (U)  SAFES  AND  CONTAINERS.  OA  Form  727  (Classified  Container  Informa- 
tion) will  be  affixed  to  the  front  of  each  container  showing  name,  rank,

30.  (U)  PHYSICAL  SECURITY.  Physical  security  will  be  governed  by  the 
tactical  conditions  of  the  area.  It  may  require  sandbagged  emplacements  and 
manned  bunkers,  perimeter  fencing,  trip  flares,  etc.,  or  restricted  area 
signs  and  perimeter  lighting  may  be  all  that  1s  required.  Whatever  the 
caseB  the  site  supervisor  must  Insure  that  local  security  Is  adequate.  In 
so  doing  he  must  also  Insure  that  technical  operating  efficiency  is  main- 
tained. All  site  personnel  must  be  completely  familiar  with  site  security 
plans  and  alert  procedures  in  effect.  (See  DIA  Manual  50-3.)

TRAINING" 
34.  (U)  GENERAL.  As  long  as  an  Individual  1s  a  member  of  a  military 
organization  he  will  receive  training.  It  1s  necessary  for  each  Individual 
to  receive  training  so  that  he  can  maintain  proficiency  In  his  HOS  and  be 
kept  abreast  of  the  ever  changing  methods  and  techniques  of  operation; 
therefore.  1t  Is  essential  that  an  effective  training  program  be  carried 
out  that  will  benefit  everyone.  This  should  be  a  continuing  and  on-going 
program. 
35.  (U)  OF  TRAINING.  The  S3,  as  trainer,  must  Insure  that  lesson  clans 
on  OF  subjects  are  prepared  1n  accordance  with  the  format  contained  1n 
Appendix  G,  FN  21-6,  for  each  monthly  training  subject.  The  OF  site  super- 
visor, as  instructor,  may  participate  In  the  preparation  of  lesson  plans 
and  Informal  training  notes  supporting  those  plans.  He  must  also  Insure 
that  lesson  plans  for  all  subjects  pertaining  to  his  detachment,  and 
required  for  the  month,  are  available  to  him  to  conduct  the  training.  He 
should  also  Insure  that  his  site  Is  on  the  distribution  11st  for  command 
Information  periodicals,  fact  sheets,  and  other  Informational  type  matter. 
With  the  materials  at  hand,  plus  some  local  improvlslons,  a  satisfactory 
training  program  will  be  conducted  by  the  site  supervisor.  The  site  super- 
visor should  set  up  a  training  schedule  that  will  convenience  all  site 
personnel  without  Infringing  upon  operational  commitments.  At  the  end  of 
each  month  a  training  report  will  be  sent  to  the  company  training  NCO  so 
that  the  training  credits  can  be  entered  on  the  Individual's  training  record. 
A  separate  record  should  be  kept  at. .the  site  for  the  site  supervisor's  file. 
•  ■*{■. 
36.  (U)  SPECIAL  TRAINING.  A  special  MOS  training  program  should  be  con- 
ducted by  the  site  supervisor  each  month  to  Insure  that  each  member  of  his 
site  1s  proficient  In  all  functions  of  OF  operations.  Training  programs 
and  lesson  plans  should  be  arranged  to  cover  such  functions  as  follows: 
a.  Antenna  maintenance  and  monopole  alignment  procedures. 
b.  Generator  operation  and  maintenance  and  procedures  for  conversion 
from  commercial  power  to  emergency  power.  If  applicable.

37.  (U)  ON-THE-JOB  TRAINING.  Before  a  newly  assigned  OF  operator  can  be 
placed  on  a  full-time  job  he  must  first  go  through  a  period  of  OJT.  A 
constructive  program  will  be  developed  to  cover  all  functions  of  OF  opera- 
tions, such  as  flash  and  reporting  procedures,  equipment  operation,  mainte- 
nance procedures  for  all  site  equipment,  security  regulations,  alert  pro- 
cedures, SOP  and  site  routine.  The  site  supervisor  will  monitor  the 
administration  of  all  phases  of  the  OJT  program.  When  the  training  period 
has  been  completed,  a  written  test  should  be  given  to  determine  if  the  new 
operator  Is  ready  to  assume  the  full  duties  of  a  OF  operator.  A  full  record 
of  this  training  will  be  maintained  with  the  individual's  on-site  training 
records  with  copies  of  these  records  forwarded  to  the  parent  unit  S-3  for 
filing.  Periodic  retestlng  should  be  given  to  all  OF  operators  to  assure 
that  top  proficiency  is  maintained. 
Section  X 
SAFETY 
38.  (U)  6ENERAL.  There  must  be  safety  regulations  published  and  posted 
to  cover  all  functions  of  a  OF  site,  not  only  operational  and  military 
functions,  but  social  and  off-duty  functions  as  well.  These  regulations 
must  not  only  be  published  and  posted  but  they  must  also  be  strictly 
adhered  to.  It  1s  the  responsibility  of  the  site  supervisor  to  insure  that 
a  safety  and  occupational  health  program  is  instituted  and  carried  out 
In  accordance  with  this  regulation  and  USA  INSCOM  Regulation  385-2,  at  the 
Or   site.  / 
39.  (0)  PETROLEUM,  OILS,  AND  LUBRICANTS  STORAGE.  The  POL  dump  at  the 
site  will  be  constructed  in  the  area  of  least  Interest  and  as  far  from  any 
other  structure  or  piece  of  equipment  as  real  estate  will  allow.  The 
storage  area  will  be  dry,  well  ventilated,  and  covered  for  protection  from 
the  weather.  An  earth  revetment  will  be  built  around  1t  to  prevent  a  runoff 
I™?e  °  fV?'    POk   should  not  ^  kePt  1n  «xcess  ^  the  amount  needed  for 
normal  operations.  In  cases  where  Quartermaster  facilities  are  available, 
only  enough  POL  should  be  stored  to  meet  basic  load  requirements. 
40.  (U)  FIRE  REGULATIONS.  A  sufficient  number  of  fire  extinguishers  will 
be  kept  at  the  OF  site  to  cope  with  fire  outbreak.  At  least  one  extinguisher 
win  be  placed  in  each  structure  and  on  each  vehicle,  generator,  etc.  Fire 
extinguishers  will  also  be  placed  in  the  billet  area  and  "NO  SMOKING  IN  BED" 
signs  will  be  placed  conspicuously  1n  each  room.  A  schedule  will  be 
established  for  the  hydrostatic  testing  of  extinqulshers.  Most  pressurized 
extinguishers  require  this  test  at  five  year  Intervals. 
a.  Fire  extinguishers  will  be  checked  monthly  to  Insure  that  they  are 
In  good  repair  and  that  the  seal  Is  unbroken.  They  will  be  weighed  to 
check  for  fullness  every  six  months.  A  ticket  will  be  attached  to  each 
extinguisher  showing  date  checked  and  initials  of  Inspector.  Insure  also

c.  At  least  one  emergency  exit  must  be  provided  for  the  billet  area. 
Exits  should  be  remote  from  each  other  and  so  arranged  as  to  minimize  any 
possibility  that  both  may  be  blocked  by  any  one  fire  or  other  emergency 
condition.  When  devising  alternative  exits,  particular  attention  should 
be  paid  to  the  number  of  building  occupants,  the  fire  resistance  of  the 
exit  components,  and  suitability  of  the  exit  for  use  by  Intended  personnel. 
Exits  must  be  clearly  marked  with  the  word  "EXIT"  1n  letters  six  Inches  high 
by  3/4  of  an  Inch  wide. 
'  d.  A  Fire  Marshal  and  Assistant  Fire  Marshal  will  be  designated  from 
among  the  site  personnel  to  keep  the  fire  prevention  and  safety  program 
current  and  should  be  monitored  regularly  by  the  site  supervisor. 
41.  (U)  SAFETY  OF  OPERATIONS.  ;  Criteria  will  be  established  for  the  safe 
operation  of  all  equipment  on  the  DF  site.  Frequent  inspections  will  be 
conducted  by  the  site  supervisor  and  maintenance  supervisor  to  locate  any 
loose  connections,  worn  or  frayed  cables  or  loose  or  improper  grounds  on 
equipment.  The  site  supervisor  should  be  alert  for  the  detection  of 
unsafe  practices  by  site  personnel.  "DANGER"  signs  will  be  placed  con- 
spicuously on  or  near  equipment  where  high  voltage  1s  present  and 
protective  shielding  will  be  provided^  Danger  signs  will  be  bilingual, 
when  appropriate.  Maintenance  personnel  should  be  Issued  3/4  steel-toed 
safety  shoes  and  these  will  be  worn  whenever  on  duty.  Safety  goggles, 
hearing  protective  devices,  and  other  types  of  personal  protective  equipment 
will  be  worn  as  appropriate.  (See  DA  Pamphlet  385-3,  Protective  Clothing 
and  Equipment.) 
42.  (U)  VEHICLE  OPERATION.  Many  man-hours  are  lost  and  property  damage 
Incurred  due  to  unsafe  vehicle  operation;  therefore,  it  is  apparent  that 
a  program  to  promote  safe  driving  habits  and  vehicle  safety  is  essential 
not  only  for  the  protection  of  site  personnel  and  equipment  but  for  the 
uninterrupted  operation  of  the  DF  site  as  well. 
43.  (U)  SUMMARY.  The  DF  site  supervisor  should  see  that  his  local  SOP 
reflects  a  safety  program  applicable  to  all  phases  of  DF  site  operation. 
Both  on  and  off  duty,  the  key  word  1n  any  safety  program  Is  "common  sense".

SITE  VISUAL  INSPECTION 
8-1.    The  site  must  be  substantially  flat  1n  all  directions  outwards 
from  the  antenna  field  for  at  least  one  wave  length  at  the  lowest  operating 
frequency,  and  have  no  more  than  a  gentle  slope  for  several  times  that 
distance.    Abrupt  terrain  Irregularities  must  be  avoided*  such  as 
excavations,  cliffs,  ravines,  cuts,  and  fills.    Hills  and  mountains  should 
not  exceed  three  degrees  vertical  elevation  from  the  site. 
B-2.    Type  of  soil  and  cover  are  Indicative  of  ground  conductivity.    Pastoral 
or  forested  land  with  uniform  vegetation,  loam  or  clay  soils  are  usually 
satisfactory.    Dry  sandy  soil  and  rock  outcropplngs  are  generally  unsatis- 
factory. 
B_3#      Since  shoreline  refractive  error  is  an  important  consideration  for 
radio  DF  Installations,  the  Terms  of  Reference' will  Indicate  required 
distances  between  OF  antennas  and  large  bodies  of  water. 
B-4.    Site  and  surroundings  must  be  reasonably  free  of  buildings,  tall 
trees,  wire  fences,  radio  antennas,  rattroad  tracks,  overhead  conductors, 
chimney  stacks,  towers,  or  other  objects  capable  of  re-radiating  DF  energy. 
No  object  should  appear  above  an  elevation  of  three  degrees.    Minimum  Dis- 
tance acceptable  between  DF  antennas  and  obstructions  are  as  follows,  but 
other  distances  may  be  specified  as  appropriate: 
a.  Scattered  small  buildings  and  trees  -  500  ft. 
b.  Overhead  site  power  and  communications  lines  -  1,000  ft. 
c.  Overhead  public  power  and  communications  lines  -  1,000  ft. 
d.  Buildings,  towers,  etc.-  not  over  3  degrees  elevation  angle 
e.  Railroads  and  over  head  conductors  (except  power  lines)  -    1,500  ft. 
f.  Overhead  power  lines:        3-11  kv  -  1,500  ft. 
11-34  kv  -  3,000  ft. 
34-138  kv  -  4,500  ft. 
Over  138  kv  (steel  towers)  -  4,500  ft. 
g.  Highways  -  1,000  to  3,000  ft. 
h.  Built-up  housing  areas  -  1,500  ft. 
1.    Fluorescent  street  lights,  neon  signs  -                                 2,000  ft.
