info on HO-10

[Keith Rowland]

Hi Steve and All:

Specs on the HO-10:

VERTICAL AMPLIFIER
Frequency Response:  Plus/Minus 3db from 10 Hz to 500 kHz
Sensitivity:         500 mv/inch deflection
Input Resistance:    50K-ohms

HORIZONTAL AMPLIFIER
Frequency Response:  Plus/Minus 3db from 3 Hz to 30 kHz
Sensitivity:         800 mv/inch deflection
Input Resistance:    1 meg.

SWEEP GENERATOR
Recurrent Type       Linear Sawtooth produced by internal
sweep                              generator
Frequency            15 to 200 Hz (variable)

TONE OSCILLATORS
Frequencies          Approximately 1000 Hz and 1700 Hz
Output Voltage       15 mv (nominal)

GENERAL
Frequency Coverage   160 thru 6 meters (50-75-ohm coax input)
Power Limits at Rear Coax Connector:  5-watts to 1-KW output

Tube& Diode Complement:

1 - 3RP1 CRT, medium persistence, green trace
1 - 6BN8 Clamper, low level RF detector
1 - 6C10 Sweep Generator, horizontal amp.
1 - 6J11 Twin phase shift tone generator
1 - 12AU7 Vertical Amp.
1 - 1V2 Hi Voltage Rectifier
4 - Silicon diodes, B-plus rectifiers

FRONT PANEL CONTROLS
FUNCTION Selector
SWEEP FREQ
TONE GEN
HO GAIN
HOR POS
VERT POS
VERT GAIN
FOCUS
INTENSITY/OFF

REAR CONTROL
XMTR ATTEN.  Attenuates 0 to 24db at approximately 6db per step.

POWER SUPPLY;      Transformer operated, fused at 1/2 Ampere

POWER REQUIREMENTS:  105-125 VAC, 50/60 Hz, 35 watts.

DIMENSIONS;          5 1/4" HIGH X 7 3/8" WIDE X 11" DEEP, including
knobs.

Net Weight:  8 1/4 pounds.

Shipping Weight:  10 pounds.

The scope will present envelope, AF trapezoid, and RF trapezoid
patterns.  It will also monitor other signals by connecting it to your
receiver. A two-tone (1000 and 1700 Hz) sine wave audio oscillator for
SSB adjustiment and other testing is built in.  Has CRT shield to
minimize stray effects on the trace.

Hope this is useful...73, Keith
