Operation:
Controls: Controls consist of Volume, Fine and Main (course) tuning.
Volume:
Set the volume control to a comfortable listening level. The AGC ill hold the audio level to this volume for all but the eakest signals. The
AGC has a slightly delayed response to keep it from overshooting hen a large signal appears. This results in a momentary “thump”. Without
the slight delay, all audio ould be lost until the AGC could recover from overshooting, hich could take several seconds.
Main tuning:
Main tuning has about a 350 kHz range in a single turn of the knob. NOTE: Tuning is “back ards”. Turning the tuning knob clock ise
decreases frequency.
Fine tuning:
The fine tuning control has about a 30 kHz range, allo ing you to tune bet een several near-by stations and to compensate for any minor
drift the VFO has during operation.
Microphone: An “electret” microphone element is required. The rig supplies the po er needed for the mic. A suitable, lo cost microphone is
available from .QRPKITS.com
Push To Talk (PTT):
Transmitting is initiated by pushing the PTT button on the microphone and then talking (duh). The PTT s itch is also used to activate “tune”
and “CW” modes.
Tune up mode:
Most 75/80 meter antennas have a fairly narro band idth so therefore require an antenna tuner hich needs to be readjusted every so
often as you move up or do n the band. Since a steady carrier orks better then histling into the mike to get a signal, a steady carrier or
“tune mode” is built into the rig.
Tune mode is activated by:
1. A very short push and release of the PTT s itch on the microphone, < 1/2 second.
2. A “beep” ill sound in the audio output, announcing the tune mode is no active.
3. Using the PTT ill no activate a 600 Hz tone hich is injected into the microphone circuit to modulate the rig. The tone is also
heard in the speaker hen the rig is transmitting. Transmit po er is typically about 5 atts in tune mode, but ill vary depending
on the microphone gain setting.
4. To exit Tune mode, perform another very short push and release the PTT s itch.
5. A double beep ill sound in the audio output to announce the tune mode is no longer active.
CW [Morse] mode:
The Survivalist can be operated in CW mode thanks to the Tune mode and microprocessor control of the T/R sequencing in the transceiver.
The difference bet een CW and Tune mode is that in CW mode, the transceiver must respond to quick changes in the state of the PTT
s itch and stay in the CW mode. Once enabled, CW mode can only be cleared by turning the rig off, then back on again.
CW mode is enabled by keying the character “H” ith the PTT at bet een 5 and 20 pm. This allo s activating CW mode ith either a
straight key or external paddle. There ill be no annunciating side tone until CW mode is enabled, so you have to mentally count the key
taps to enter the mode. If not enough pulses are detected, the rig may enter Tune mode instead of CW mode. There just has to be four on/off
pulses detected in less than ½ second to enter CW mode. When CW mode is detected and enabled, the audio output ill annunciate “CW”.
The Survivalist ill no operate as a CW transceiver, allo ing for cross mode communication in the phone band.

Assembly tips:
●Presort the various parts and place similar types in small paper picnic bo ls. Resistors in one, capacitors in another, and so on.
This ill not only speed assembly, but ill also help keep parts from getting lost. If you like, you can also cross check the parts
against the parts list as you do this to make sure you have them all.
● Be sure to print out the black and hite parts placement diagram as this ill be easier to reference most of the time. You really
don't have to print out the hole manual if you have a laptop or equivalent on your orkbench to vie this.
●Hopefully you already kno ho to solder and don't need to be told to heat both the component lead and the solder pad ith the
tip of the soldering iron. Be stingy ith the solder. You don't need much, only enough to fill up the hole. Using 0.020” diameter
solder allo s better control then the more common 0.032”.
●The circuit board is assembled in the order of parts height. Lo profile parts starting ith resistors are installed first, the
progressively taller parts are added.
●Q16, the transmitter output transistor ill be the very last part mounted and only after the board has been ired into the case and
tested.
●If you bought the Digital Dial option, it ould be a good idea to built and calibrate this first. The Digital Dial can be used to adjust
the VFO coil to put the tuning into the proper range.
Cabinet prep:
●There is a “Modulation” indicator LED on the board, hich you might ant to bring out to the front panel. This ould require drilling
a small hole someplace on the front, hich ould best be done no .
●If desired, paint the cabinet.
●Tape the red film over the display cutout on the front panel. If you'll be using the optional Digital Dial, snip the corner of the film to
uncover the s itch hole.
●Attach the tilt bail to the bottom of the case and add the four rubber feet bumpers.
●Attach the decals as described belo .
The decals are applied the same as model decals. Cut around each group of text or symbols you ish to apply. It doesn’t have to be perfect
as the background film is transparent. Apply the decals before you mount anything to the chassis. Use the above picture to get the correct
spacing around the holes and cutouts, as it is very easy to do a great decal installation and have a portion covered up ith a knob
Thoroughly clean the sur ace o the panel to remove any oils or contamination. We have ound that moving the decals into
position on bare aluminum chassis is di icult, due to the brushed sur ace, so we advise pre-coating the chassis with the Krylon
clear be ore applying the decals, and then, a ter as well.
Trim around the decal. After trimming, place the decal in a bo l of luke arm ater, ith a small drop of dish soap to reduce the surface
tension, for 10-15 seconds. Using t eezers, handle carefully to avoid tearing. Start to slide the decal off to the side of the backing paper, and
place the unsupported edge of the decal close to the final location. Hold the edge of the decal against the panel, ith your finger, and slide
the paper out from under the decal. You can slide the decal around to the right position, as it ill float slightly on the film of ater. Use a knife
point or something sharp to do this. When in position, hold the edge of the decal ith your finger and gently squeegee excess ater out from
under the decal ith a tissue or paper to el. Work from the center, to both sides. Remove any bubbles by blotting or iping gently to the
sides. Do this for each decal, and take your time. Allo to set overnight, or speed drying by placing near a fan for a fe of hours. When dry,
spray t o light coats of matte finish, Krylon, clear to seal and protect the decals, and allo to dry in bet een coats. All decals come ith t o
complete sets, in case you mess one up.

Resistor, RFC and Diode placement
●Caution: The 1N4148 and 1N5231 diodes look identical, read the numbers carefully on the side of the part. A magnifying glass
maybe required. Observe polarity as indicated by black line on one end of the part and diagram.
●Sorting the resistors into their various values before hand ill speed up assembly.
● Install all the resistors of one value at a time. The location/value table is set up for this.
● Parts are numbered on the board from left to right, top to bottom in diagonal ro s.

Sockets, crystals, trimmer resistors and DC po er connector:
●Parts to be installed are highlighted in gray in diagram belo .
●Install crystals. Push flush to board.
○Use resistor lead clippings to solder top edge of X1 through X5 to the solder pad next to the top of can.
●Install the IC sockets.
○The notch on one end of the socket should be at the same end of the part outline hich also has the notch. Note that not all
the sockets face the same direction.
○Make sure all the pins are sticking through the holes in the board before you start to solder. Sometimes a pin ill fold over
under the socket as it is inserted. If this happens and is not noticed, it can be very difficult to remove the socket to fix once
you start soldering.
●Install the t o trimmer resistors. They ill go in easier if you first flatten out the kink in the leads ith your pliers.
●Install the DC po er jack.

Capacitors
The numbers on the small MLCC (Multilayer Ceramic Capacitors) can be hard to read. A magnifying glass is recommended. You don't ant
to mix up the values, as that could lead to problems not easily found. As ith the resistors, sort the caps by value and type and install all the
same value/type in batches. Since there are a lot of 0.1ufd caps (104), install these first. Some caps may need to have their leads reformed
to fit into the hole spacing properly. Electrolytic caps are installed after the small caps.
