Onward-to the main components of the PRC-25, the
AN/VRC-53 and the AN/GRC-125.
RT-505
A batch or two of the CX-4655/U special purpose
cables that tie the RT-505 to the amplifier-power supply
were cut a little short when they were made.


And, when you connect the components, that sharp
U-bend pulls just enough cable to make the connectors
less than waterproof.
So-o-o-o, if you can spot wiring when the cable's bent,
a loop or two of insulating tape at the base of the con-
nector should keep out moisture. It should serve in an
emergency, till you can get a new cable.


Finding a Joe who's mad enough at an AN/PRC-25
series radio set to badmouth it is about as easy to do as
sitting on a bamboo spear tip.
Like, when the geniuses back at the drawing boards
dreamed up those little gems, they must've had operators
and repairmen kibitzing over their shoulders.
For the operator, the sets are almost as uncomplicated
as using a pocket portable.
So a few cautions, some PM palaver and an inside
word or two on a couple' short-term shortcomings should
keep you communicating.


2 A ~'I~i


The VI (2DF4) tube, FSN 5960-892-3689, and trans-
mission range depend pretty much on each other, so if
you lose range, the tube is a good suspect. Fact is, you
might test the tube periodically just so's you'll be sure
you have range when you need it. -

AM-2060
The amplifier-power supply of the
series rates a special few words.
Like, when you're using the VRC-53
or GRC-125 configurations, and you
can't turn the radio set power on or off
at the AM-1780 amplifier unless the
power switch of the AM-2060 is first
set to OFF. In which case, watch it!
Get your direct support to update
your AM-2060 pronto! The connector
wiring in the rear of the amplifier has -
to be changed. Naturally, before you
suspect the amplifier, make sure the AM-1780
link in your MT-1029 mount is set for no
remote operation (power control from ,r.
the AM-1780, that is). O
For the mount bit, see paras 4a and i
4b of TM 11-5820-498-20., J "'AR
If the AM-2060 wiring goes uncor- o

LOCK IT EASY


Next time you've got your channel
with the RF channel dial of your T-302
transmitter, think a second before you
follow through.
AN/TRC-24 radio sets have tum-
bled because the operator got too con-
scientious on that next step.
Like, your next move is to lock the
channel dial. Fine. Commendable. But
you don't have to turn the lock clear
off the panel of the T-302. Snug it
down enough so that it holds the RF
channel dial firm.
Don't put so much torque to it that
you have to turn the transmitter in to
have its channel lock innards fabri-
cated. It could be a long wait.

Dear Sergeant F. J. W.,
No sweat. FSN 5330-905-6032 will get it for you.
In fact, the O-ring fits all U-182/U and U-229/U
connectors, like, f'rinstance, those on the M-80 micro-
phone and H-161,MK-525/G and MK-526/G head-
set-microphone. The stock number is getting added
to parts manuals or to the functional parts lists of
the basic TM's.
To keep the O-ring in place ... and to lengthen its
life ... give it a light coat of silicone compound, FSN

FOR A
HEALTHY
HEADSET


\\ hat ith the push on for new FM-series equipment
and such, things are getting a bit right on replacing com-
ponents of the old standardized radio series-'specially
audio accessories on sets like the AN/GRC-3.
In the "real tight" class is the H-63/U headset-mike.
Give that babi plenn TLC. because getting a replace-
ment is going to take time. time. time, Tom. Also, if
that little joker needs repair. get it done now. Never let
it get to the point where it has to be replaced. Like. it's
tight.













Funny thing about bias current and radio-teletypewriter sets. If the bias supply
is set too high, it can burn out the modulator of your set.
F'rinstance, whether you're working with an AN/GRC-26D, an AN/VRC-
29 or an AN/GRC-46, the bias current should measure 60 milliamperes.
Since all sets use the TT-98 and the TT-76 teletypewriters, a couple' perti-
nent paragraphs in appropriate TM's should straighten you right out-especially
if radio repair is your specialty and
Steletype work isn't.

CHECK YOUR
MANUALS FOR THE.

Para 2-8c and fig 2-7 in TM 11-5815-
238-12 (Dec 65) on the TT-76 and
para 2-13 and fig 2-9 in TM 11-5815-
200-12 (Feb 66) on the TT-98 fill you
in on quick bias adjusts on the teletypes.
It's a must to make the adjustments
at initial installation, when changing
from commercial power to another
source, or after any adjustment of the
power supply.
In addition to the method in the
TM's, you can use a TS-352 multimeter
by placing the probes across the bias
terminals.
Place the TS-352 setting in the 100
MA range, and adjust the bias of the
TT's to 60 MA.

The only replacement item is its 16-

GOTTA LEAKY SAS?

GET 'ER

FIXED




A leaky or drippy spigot can be mighty irritatin' but it won't get next to
you half as much as a leaky hydraulic line in the SAS (Stability Augmentation
System) of your Chinook (CH-47).
If the side or overhead padded lining is spotted by fluid, you kndw there's
trouble dripping.
Inspect the cable's swivel joints and keep an eye peeled for SAS line leaks.
When that oozin' fluid gets into the variable resistors of the SAS facility's
amplifiers, it's bad. _


It can knock out both SAS's and replace that feathery flying feeling with
more movement on the controls and a rougher ride.
But, even worse .. that hydraulic fluid leaks from the overhead cable's swivel
joint and gets inside the overhead circuit breaker panels or into the lower con-
sole's control panel.
In there the fluid can eat the insulation off wiring and cause communications
failure.

Dear Sergeant J. A. L.,
Here's how I see it:
TB 746-93-1 (Oct 64) says the vehicle number should be its sequence number
in the normal order of march in the unit.
AR 320-5 (Apr 65) says a trailer is a vehicle.
Therefore, you'd give the trailer the number after the number of the truck
normally pulling it. 1/a -

In cases of separate responsibility for
split periodic services, you'll need
duplicate 314's for smooth scheduling
of these services.

A. The examples on pages 3-4 and
3-5 in Ch 2 to TM 38-750 and on page.
8 in DA Pam '50-38 (2. Aug 64) show
that additional information can be writ-
ten in the "remarks" space; no other
s mbols are authorized.
Since you prepare the DD Form 314
in advance (at least I month). if you
spccify the lubrication service it will
allo2 the shop to organize its men
and equipment before the equipment
arrives to be serviced. This increases
shop efficiency and results in equip-
ment getting back to the unit faster.
There is no other space for "re-

short.

A. When the S senice is not per-
formed at the same time as the L serv-
ice. you do S lubing onl] if inspection
shows it's needed, like the TM sa.s.
But there's no "if" in the L service ...
.ou lube just as the LO calls for it.
Depending on which equipment's
involved and what's called for in its
LO, usually >ou can do some or all of
the six-month L services along with the
S services spelled out in the TM. The
most practical time is when lubes are
changed for the seasons, about six
months apart.
This is real eas) to schedule for L
services that come "semi-annually or
3,000 miles," the same internal spelled
out for S services. L services that come
"1,000 miles or 6 months" and "6.000
miles or 6 months" can be worked in
with S services too if mileage doesn't
come first and upset this setup. The 10
percent leeway ma. help you get 'em
together.

Here's a handy guide for you crew-

m.. The M107 and M110 are the same
in every way except for their louden-

Sis real fine-saves your own muscle-
power. But hydraulic and electrical

ber that.
Here're some defects that could really
foul up your firing mission. So, get on
em quick and either fix 'em yourself
or get the word to support.

CANNON TUBES-Lands raised, chipped, corroded.

The tube on the 175-mm is chrome-plated,
so if you find any flaking, don't worry about
it. However, be sure you keep track of your
tube's EFC (equivalent full charge) entries in
column g of its DA Form 2408-4. Any time
you have a doubt about the serviceability of
the tube, ask your support guys for a bore-
scope and pullover gage reading. The charts
in TB ORD 1054 (6 Dec 63) will come in
handy for figuring EFC's after every firing.


LEVELING PLATES-Chipped, painted, dirty.
(Like the TM says, protect these plates at all
limes Especially. don't lay tools and other stuff
on em. They've gol to be in A-1 shape for bore-
sighting. (lean these plates after every day's firing
- and don't point 'em.)

(Any time the oil index sticks out less than 0 20 in,
that's about 3/16ths, you have to reestablish the oil
reserve in the recuperator cylinder. You'll find the scoop
an this in para 80b of Change 4 (31 Mar 65) to your
-10 TM. Never fire the weapon when the oil index is
withdrawn into the recuperator cylinder head, since no
reserve oil is present.
And keep on eye peeled for leaks. Up to three drops
in five minutes ore allowable But if it leaks any faster
than that, get word to support.)

BEWARE THE SHORT RAM
s ?7....,L !,,, ,,


.
Here're some of the defects and bad operation practices that'll cause a short
ram-meaning the chain won't extend far enough to seat the projectile in the
175-mm or 8-incher's tube:


1. Easing the valve handle or
creeping or feathering. You
want that rammer control
valve wide open (full ram)
throughout the entire ram,
man


2. A bent or misalined loader
tray or trough that causes
the rammer chain to get
hung up.


3. An improperly adjusted
trough latch which causes
the trough microswitch (tray
interlock switch) to lose con-
tact. This'll result in flutter-
ing in the chain-a short
ram due to intermittent loss
of power.
L..


4. An improperly adjusted
loader-rammer pivot stop
which also causes the micro-
switch to lose contact and a
fluttering in the chain.


5. A rammer check valve or flow regulator metering
valve that's put in backwards could also give you a
bum ram. So, if the chain extends fast and comes back
slow or if the chain extends one distance one time

6. A bent or sprung rammer rack roller
that'll let the rammer rack climb
over the teeth of the rammer gear.
This'll result in loss of power and a
short round. And it'll mean you'll
have to retime the rammer chain.

It's real important that you crewmen
on the M107 especially give the powder
chamber a real good swabbing after
firing every round. Use cold water and
plenty of muscle. Besides cleaning the
chamber, the cold water'll cool it off
and prevent a hot round. You should


also swab the mushroom head of the .M it n l
obturator to cool that off.

OK for those two wheels. Now test the next two wheels and the two after that
till all eight wheels have been checked out. If any of them fail to check out OK,
get your support guys on the job.
O'course, this kicking could also mean the traversing/elevating slip clutch
needs adjusting or the equilibrator pressure's wrong, or your spade's not em-

SIGHTING AND FIRE CONTROL
No matter how well you maintain your gun or howitzer, it won't be worth a

to the sighting and fire control equipment. But go real, real light on how you
handle 'em. These instruments are delicate.

M107-M110 RHEOSTAT ROUNDUP

HERE. ARE A
COUPLE OF
ILLUMINATING
S TIPS. So what's new, pussycat?
If you've got any of these SP jobs M 107, M 108,
SM109 or Ml 10 this is new for true-blue you.
The rheostats for some of the fire control instru-
ment lights are going kaput. The way the electrical
wizards figure it, the current surge,when you start
j the vehicle,is ruining rheostats that are left in the
ON position.
The cure is simple, make sure that all electrical

are OFF before sou start the vehicle.



If you have an M I08 or M1109, you can fall out ...
but if you have an M107 or M 110, here's a tip.
The rubber moulded part of the reticle illumi-
nating light on the M 138 telescope mount is getting

Hey, you guys with the new-type mechanical-time fuzes ... y'know, the kind
your OVE fuze setters won't fit 'cause their set lugs are closer to the tip of the
fuze than they are on the old type.
You can get an M63 fuze setter set (FSN 1290-966-9318) through regular
supply channels if your outfit's equipped with the MlO2 105-MM light towed
howitzer or the M106 and M1O6AI 107-MM SP mortar.
Or, if you've got the 105-MM thru 8-in guns and howitzers, or the 4.2-in
mortar, you can get a temporary XM34 fuze setter set (FSN 4925-078-4367) till
the M63 shows up in your BILL.
Order this XM34 from Letterkenny Army Depot, Chambersburg, Pennsylvania,

Watch this, though! If you get one
of the straight-handled "interim"
M11E1 cleaning rods (FSN 1005-903-
1295) ask your armorer to get the
handle bent before you screw the cham-
ber brush into it.


The new double-end lube case (FSN
1005-791-3377), holding PL Special
(FSN 9150-273-2389) in one end and
rifle grease (FSN 9150-248-3480) in
the other, is a real gem. Your armorer
can fill both ends for you, and refill,
too, when you run low.


The new swabs are about one-fourth
the size of the cal-30 types you've been
using the ones you used to have to
slice four ways. These new ones will
save you a lot of time in the cutting
department.


-BT-NO CHANGE HERE







Here's something to keep on top of your mind, though, when you get these
bright new gadgets. They don't change anything in the rules. You still can't
take the lower receiver apart to clean it. That note on page 3-8 of the
Change 3 dated 1 May 65 to your TM is still the law.




















If you've got the locally-fabricated Now, these two cartridges look ex-
M149 subcaliber device (FSN 1005- actly alike, so you can't tell 'em apart
878-0204) for spouting 7.62-MM tracer by eyeballing. However, there're two
bullets from M67 90-MM reckless rifles, other ways to identify 'em:
*be sure you use this ammo:
1. (heck the lot numbers These are the ONLY
M62 cartridge with GMCS (gild- (hk Inumber numbs These a the ONt

NCTHING LC-12000 thru L-12303
E L5E. r RA-5000 thru RA-5224
WC( 6000 thru W((C6088

2. Give 'em the magnet test, like so:



L L


If you by mistake use the M62 car-
tridge with GM (gilding metal) jack-
eted bullet, you'll wind up with no
tracer at all. The ammo may break up
and stick in the barrel or give you poor
accuracy. You might even get hurt by
fragments in the backblast.


Put a magnet (the dime-store variety
will do) against the bullet. If the mag-
net sticks, it's the right ammo.
If the magnet won't stick, it's the
wrong ammo. Turn it in pronto.
If there is still any doubt in your
mind, turn the stuff in anyway and be
sure you get your ammo from batches
bearing the listed lot numbers.
















You puzzled when it comes to totin'
up demands on your DA Form 2527 '. ,
"Record of Demands" cards? .
You needn't be if you think of it this v. a
A demand is one request. t
To put it another way:
A request places one demand on your stocks.
A demand (the request), of course, can ask you for a minimum of one each,
or it can ask you for 100 each, or more, of a specific repair part, or maintenance
item. But in each case, it's only one demand.

Water dripping down your collar from the seams of your small general pur-
pose tent (FSN 8340-753-6570) can make you miserable. _j__ _
But you can cure water seeping in through the threads with a mix of textile
preservative and solvent, provided you can get the tent dry first. Mix equal parts
of the preservative and solvent, paint on, let it dry for a full day, do the paint-
and-dry act again, and you should be rid of the splash.
You can get a gallon of preservative (Mildew Resistant Compound, textile)
with FSN 8030-290-4382 from DoD Cat C8000-IL-A (1 Jan 66), and a gallon
of Dry Cleaning Solvent with FSN 6850-281-1985 from DoD Cat C6800-IL
(1 Jan 661
