R1034A Control Line Test
Set Manual 720 kB PDF
Photo of the R1034A
tester Manual 6881069A77-O
Note that the R1034A Test Set and the R1034B Control Line Test Set are two very
different products inside despite the fact that they have a similar purpose and
an almost-identical model number.
Many dispatch systems had the base station or repeater at one location and the
control point at another. Setting up or maintaining the connecting phone line
required the ability to make both DC and AC measurements. Motorola and Triplett
together designed the Model R1034A Control Line Test Set, and the mixed background
of the Motorola 2-way engineers and the telephone telecommunications background
of the Triplett engineers shows in the design. This unit is essentially a specialized
AC and DC VOM and an audio generator all in one ruggedized package (by using the
existing housing from the Triplett 630-series VOM they could take advantage of
the existing accessories including probes and carry-cases). The unit measures
telephone line current, telephone line noise, DC resistance and both AC and DC Volts,
and all measurements are using ranges that are optimized to telco control lines. This
test set will also send audio tones at an adjustable level and measure received tones
in dB on the meter. A pushbutton adds a 10dB attenuator in line. A switch on the
lower left of the panel selects bridged or terminated mode. The unit was built
into a sturdy protective carrying case with a pocket in the lid for the book and
the probes, and a snap-hook shoulder strap for carrying. There is a 1 amp
fast-blow fuse that is in line with the volts and ohms measuring circuitry inside
the battery compartment. DO NOT replace it with a slow-blow fuse. The test set is
powered by two common 9 Volt batteries and one D-cell battery - and the
second 9V battery is hidden behind the "D" cell!
Before you buy a second-hand R1034 make sure that you open it up and check for
corrosion caused by leaky batteries (this is the voice of experience speaking
on the fuse and the battery...).

Note that the R1034A Test Set and the R1034B Control Line Test Set are two very
different products inside despite the fact that they have a similar purpose and
an almost-identical model number.
This is a redesigned and updated version of the above. Triplett sold this unit
as the "Model 4 Subscriber Loop Test Set" for doing telephone circuits. The text
portion of the manual was scanned by Eric Lemmon WB6FLY, Richard Carlson N9JIG
provided the schematic, and Bob WA1MIK cleaned and merged the whole thing. Also
note that there are five batteries in this unit: two 9 volt (B1 and B2),
two 22.5 volt (B3 and B4), and one 1.5 volt C cell (B5).

Manual 2.9 MB PDF 6881021A05-C
This is an AC voltmeter that covers 1 millivolt (-72 dBm) to 300 volts (+52 dBm) in
12 ranges, and is +/- 2% from 50 Hz to 300 kHz, or +/-3% from 20 Hz to 1 MHz.
The S1051 is battery operated only and used a single 8.4 mercury battery (Mallory
TR-136), which is no longer available. It works just fine with a standard 9 volt
battery with a 470 ohm resistor in series with it. The S1053 series is AC or
Battery operated, the AC adaptor provides 9 volts AC. It's easy to convert an S1051
into an S1053 by adding a leftover 9v DC wall wart and the missing components (the
"C" version manual covers both units).
The SKN6001A is the "official" test lead kit that is used on several Moto measuring
devices. It is a 30 inch length of RG-58-style shielded cable with a standard 2-pin
bannana plug on one end and a pair of insulated alligator clips on the other.

and types: Eveready E135, Mallory TR-135, or Ray-O-Vac T-135. If you have one of
these you may end up using an external battery pack or a DC wall-wart style power
supply. There is enough room inside the case that you could add a 6v three-terminal
regulator with one silcon diode to raise it 3/4 volt (which would deliver 6.75
volts), then power it with a 12vDC source. 6881114A04-D

T1034 RF Signal Generator
Schematic
External photo
Internal photo
All our original source had was the pullout schematic - he's still looking for the
rest of the manual... If anybody has it, let us know.
The T-1034 RF generator is a relabeled Measurements Corp. Model 80 generator. The
original Model 80 (1944 vintage) ran from 2 MHz and went up to 400 MHz and were built
by various companies under military contract under the designation TS-497A and TS-497B.
The later 80-R model dropped the 2-5 MHz lowest frequency band and replaced it with a
new 400-475 MHz highest frequency band (the mechanical design limits the number of
frequency bands). The basic RF design relies on a 955 acorn triode connected as Colpitts
oscillator. The 955 tube sits in a round silvered can (visible in the internal photo)
surrounded by the various oscillator coils, which rotate into position with the band
switching knob. The mechanical internals are beautifully laid out and a fine piece of
precision work rivialling a good watch. Because the oscillator delivers the output power
too, modulation is limited to 30% and is AM only - but there is enough FM in the output
to be usable. The RF output power is induction coupled to a variable attenuator. The
80-R was built through the 1960s.
Technical Manual TM 11-5030A (3.9 MB) is for the
TS-497B/URR military version of the Model 80. There are enough differences that we'd
like to have the regular manual also. As far as military manuals go, if anyone has a
copy of the later TM 11-6625-253-12P we'd like to get a copy.

The R20xx "B" and "C" models are almost identical, close enough that the "B" manual can
be used with a "C" model and vice versa. The "A" and "D" models are vastly different.
Things like the power supplies, front panel, and most of the circuit boards are used
in all models; the 20XX number merely determines what optional features are present.
For example, the R2021D is an R2001D equipped with the trunking option.
Most articles and manuals consider the R2001 to be the base / generic model number.

Turning the intensity down on your service monitor will definitely prevent burn-in of
data on the CRT phosphor screen, however everything else is still running, generating
heat, and aging. The CRT filament is heating the CRT cathode and emitting electrons.
Those elements have a limited life span and don't stop aging if you just turn the
intensity down. You're better off putting the unit into Standby (to charge the battery
and/or keep the ovenized high-stability reference oscillator hot) or shut it Off. Even
when off, there's still some small power being drawn, and lightning can still get in
through the power line, so unplugging the unit is really the safest way to go.

If you decide to remove the knobs and clean the front panel of your service monitor, you
should make a large paper drawing of the knob location first and put each knob, or pair of
knobs, in their respective locations on the drawing. Some of the concentric knobs have a
different hole size, and a little preparation beforehand will save you a lot of aggravation
when you put the knobs back. There are three concentric dual pots: Focus/Intensity, Vert/Horiz
Position, and Duplex Coarse/Fine Frequency. There are three concentric switches with pots:
Horizontal Range/Vernier, Vertical Range/Vernier, and Trigger Mode/Level. Also, some of the
larger knobs have two pointers on them, not just one. While you have the knobs off, clean
them in some hot soapy water and consider using something like Liquid Paper or White-Out or
other white correction fluid to re-paint the indicator lines on those knobs that have them.

Is the fan on your R20xxB or C-series service monitor noisy or broken? A good replacement
is the AC Infinity Axial model HS9225A-X and is 92x92x25mm available from
here.
It comes with two finger guards, a 4ft AC cord, mounting screws, and a booklet, all in a nice
foam-lined box for about $18. Bob found the supplied screws were way too long so he used
some shorter #6-32 hardware instead. You only need one finger guard. He cut and spliced
the fan connector end of the AC cord onto the existing fan cord on his R2001B. Remember,
the fan blows air out of the rear of the service monitor. The D-series uses
the same dimension fan but it's 12VDC instead of 120VAC (see below). The A-series has no fan.

acquired the equipment from Motorola to fully support the R2600-series Communications
System Analyzers. They can provide calibration, repair, and refurbishment and is
offering factory support and service contracts ($1200 annually, includes calibration)."

Farrell N3FS reported via email: "I just went through replacing the memory battery in an
R2670B service monitor. The original battery was a Plainview Batteries PMB 3.6B mounted
to the rear of the processor board. In the parts list from the service manual RLN-4120B,
this is BT1, p/n GG-6026385A001. Of course it is no longer available. It looks like a
cylinder about 1/2 inch tall and 7/8 inch diameter with 3 PC pins. A Varta 3V150H fits
perfectly. You can find these on the web. This battery has a 3-pin pc-board mount. The
original specs were 3.6 Volt, 140 mAH, Ni-MH. It mounts to the board perfectly. Changing
it and running the internal CAL procedure restored normal operation."

There's about 1.5GB of additional Motorola Service Monitor information, with some duplication,
that was sent to repeater-builder anonymously on a DVD. It's stored at our sister-site
that can be found here (Motorola Index #3).
