correctly shows the estimated cost breakdown for Items 1 and 2; in addition,
Page 2 of Exhibit "C" shows the estimated cost breakdown as applying to
Item 3.
Contractor wishes to inform the Government that the estimated
cost breakdown on Page 1 applies to Items 1 and 3 and the estimated cost
breakdown on Page 2 applies to Item 2.

TICIINICAL DTS2USEI/ON
The followtsg dieouesion outlines the method by which the Contractor
currently expects to proceed with the Work? severed by this yroposal. This
lexhibit is not indended to modify or limit the Statement of Work as set forth
in Aschibit "A'.
An operattomt need has boon envisioned requiring highly trans-
portable equipment; designated the BR-160 capable of receiving and recording
118-16A and PS-16B rield Unit treeemiseions. Correctly, these treeemdssions are
being received as racordedby the large AS and AS-4A Base Tersdnale. How.
ever, this new eormept will permit receiving eqtapment to he loftiesd at
stratteic positions now denied the larger BieseTerelaals. The propoaed 8,146
soy be stationed at SUb-Base Installations as aroma of slaking it cramps*
and easily trensportUble. Use of this new equipment has the further adventage
of releasing the larger Base-Terainele for high-speed, hi YO] traffic
for which they vere prinforlay. denten*.
!Arcing preliminary discussions with Government engineers, it was
agreed that the appromdivill be *loft Line* now being established by the AS-5
Sub-Base ,%lmenalcation Sqaipmeet. It Is planned that two packing canes viii
comprise the syeteo. One case will *contain reeeiving, reeognition and'USie
? elements, and the other Mlle will contain the reeorder sad eystes power supplies.
Meemfist as is possible, AS.5 designs will be used; however, in those *yeas Where
new designs are neceseary, teehniques similar to those met 'in the ?041,131 be
employed. Deosesse of somewhat similar field operation condition* between thi
AS-5 end the eP-16, the underlying philosophy will be to make the units similar
in oder that training of operating sal maintenanee peersonnelp,as well as
obvious logistics problemeotmey

in the B146 has been avoided ta order to eptiedse portability and to preserve
space. Ts manrlocations, it may be diffietat to erect separate arteteae,
parlaularly if they ?may a large area, as would eenventioaally be in the ease
ea.* a pair Of Ohnebics are employed. Ay emitting receieurdivereity, this area
as well as the *is* and weight of the System are substenttnae re:eetd. While
actealfield tests of predeeesOor equipmeut elearly4Weethe:virtues of receiver
diversity, it is intended that the inereased portability off. by the proposed
system viii allow its use in locations vhere diversity reception isnot essential
to aueceasful operation.
If under extensive ume, it is 'Chown that diversity rept Len would
s4botantially increase the effeotivenees of the viten, thee the eqaipment
can at a later date be easily retrofitted. The proposed syst?emerill be constructed
eith this ohject in mind. Pertinent wiring viii be brought out to a oonnector so
that a third drawer, containing a second receiver front end together with
diversity coning circuits nay be in the future easily added if. desired..
In this case, the added area require& for the extra entenas. gee possibly be
minimised by employing a horiseetal tong-wire together with a vertical whip
to provide alarization diversity.
A simple test eimeletor will be designed, Packaged and looated in
the receiver ease. This devise will function to generate a group of pulses
representing alI marks for reeogmition, an RY pattern, or a standard mensage
pattern convenient for testing* This will be accomplished by a ottup of
standard modUles and a tuning fork csosilleber. The tuning foe& will eat as
the stable freepency aaurce. The pulse output of this logic viii be eonvorted
to r-f in 2 ko steps at some frequency within the pass band of the receiver.
This technique Ls sisdlar to that employed so succeesfelly in the AS-4 pulse and
r-f simulators. To certify that the egelpeent is performing eorreetly, the
operator switches the r-f front-end tarret to the 'text" channel, and after
suitable ears up time depresses the T1ST button. This elation cameos an
elettronisally generated test signal to be transmitted to the reaeiver front
end end thence Vara the entire system vbere it finally appears as recorded
pulses from the output device. A, brief study of the simulated message will
reveal the status of the equipment.
Spares are included in this proposal on the basis of one maul,
for ;Noah different type of active module used. It the number of identical
modules is large, then two spares Will be included. Other miseellaneoua
components eill also-be included as spares, 52 experience indicates the need.
Minimum drawing*, inoluding sehematics, are a part of this pro-
posal. In this case, minimum refers to those drawings necessary for use by
model shop and skilled feetory personnel to fabrioate and partially test all
units following the first. Final testing will be accomplished by eganiering.
Its. 24 the unit cost for febriention of additional RR-16 Receiver
units, is quoted eeperatoly. In the small gametal.* requested by the cognisant
Government engineer, no appreciable wet differential can be effected for
fabrication of additional units. Therefor*, all PR-16 units fallowing the

An informal instruction manual, listed as Item 3 in the
3tatemant of Work, is also a part of this pronosal. This document will
cover theory, operation and maintenance of the equipment, primarily fc_r
use by operation and maintenance personnel. All progress will be reported.
in the usual Monthly Progress Letter, and no quarterly reports will be sub-
mitted.
An 7/-16A or :ti-1611 ?lead 'Jun will be required by Contractor
on this program, as G7.10, to be used during the development and testing phases
of the work.
