3. Slowly tune L4 back and forth with the insulated tuning tool to locate the
146.0 MHz test signal.
OPTION 2: Calibrating with a 2-meter HT.
Set the HT to its lowest power setting and connect a well-shielded 50-ohm
dummy load or a 1/2-watt 47-ohm resistor to the antenna jack. Set the mode
switch for direct operation (no transmit offset). Physically separate the HT from
your VEC-1002K by several feet during the test, and disconnect any external
power cords, speaker-mic cables, etc. that might act as an antenna.
WARNING: Do not, under any circumstance, connect the
output of the HT directly to your VEC-1002K
antenna jack--immediate and serious damage
will result!
Connect a 47-ohm resistor to the VEC-1002K antenna jack, and plug in
headphones or an external speaker--keeping the cord away from the HT.
1. Set TUNE to 146.0 MHz and SQUELCH counter-clockwise (open).
2. Power the radio and set VOLUME for a comfortable level.
3. Key the HT's transmit switch. Slowly tune the slug in L4 until the HT signal
is heard.
4. Confirm the signal you hear is being generated by the HT (click PTT on and
off).
OPTION 3: Calibrating with a Vectronics or MFJ Antenna Analyzer.
Any Vectronics or MFJ antenna analyzer with VHF coverage may be used to
generate an alignment signal. Set the analyzer to 146.0 MHz and position a few
feet from the VEC-1002K.
Warning: Do not connect the analyzer directly to your
VEC-1002K, or damage may result.
Install a 47-ohm resistor on the VEC-1002K antenna jack and follow the test
procedure outlined above for alignment using a HT. If your analyzer has a built-
in frequency counter, you may also calibrate using the direct-measurement
procedure outlined below (check your analyzer manual for counter operating
instruction).
OPTION 4: Calibrating with a frequency counter.
Your VEC-1002K features a buffered test point for measuring oscillator
frequency with a digital counter. Locate this point on the diagram below:
