Introduction
The LP-100 is designed as an accurate instrument for monitoring station performance. It provides a number of unique features not seen
before in a ham radio wattmeter.
The most obvious of these is the vector display. This display shows the complex impedance of the load in two ways. The top line of the
display shows impedance in polar form… i.e., magnitude and phase of the impedance. The bottom line shows the real and imaginary
components of impedance… i.e., R +jX. The parameters are displayed in a range of 0.1 to 999.9 ohms. Phase is displayed in 0.1
degree increments from 0-180 degrees.
Features include…
•
PLED display with bargraphs for power and SWR, along with numerical readout for both
•
Professional dBm / Return Loss display
•
50 mW to 2500W with four autoranging scales
•
Power display resolution of 0.01 to 1W depending on scale
•
Frequency coverage of 1.8-54 MHz, with automatic band-by-band compensation
•
Z, R, |X| display from 0-999.9 ohms each
•
Separate coupler with 50 ohm ports for uncluttered desktop
•
Peak-hold numerical power readout with "hang" characteristic for power and SWR
•
SWR accuracy < .15 (5%) from about .1W to 2500W, .05 typical
•
Power accuracy is 5% typical at any rated power level or frequency from .5W to 2500W after calibration, usable to 0.05W
•
Can be easily matched in the field to external standard to within 0.1% on each band
•
Power display is actual power delivered to the load ( Fwd minus Ref power).
•
SWR Alarm system with set points for Off, 1.5, 2.0. 2.5 and 3.0.
•
Windows freeware Virtual Control Panel for software / remote control
•
Support within TRX-Manager for direct remote monitoring
•
Advanced charting capability for SWR, RL, Z, R, X and phase angle vs. frequency
•
Built-in bootloader to allow for firmware upgrades to be downloaded and installed.
•
Call sign screen saver to extend life of display
•
Direct input for bench testing & field strength measurements, -15 to +33 dBm.
•
Conforms to FCC Part 15 A & B, ICAS and CE radiated emission limits, tested and verified by accredited lab
This manual will address the assembly of the LP-100, initial checkout, calibration and operation. You may wish to read through the
circuit description and study the schematic before beginning assembly to familiarize yourself with the project.
It is highly recommended
that you thoroughly read through the Assembly section before even unpacking the LP-100 kit.
RoHS Statement
The EU adopted a set of standards for the “Reduction of Hazardous Substances” in July 2006. There is considerable confusion over
which devices and companies are affected by the new rules. It is our opinion that home-built kits are exempt from this legislation, and
there may well be a further exemption under the heading “Measurement Equipment” for the LP-100. Also, since TelePost does not have
a presence in Europe, we do not import to or export from a member State, as stipulated in the rules.
Regardless of these exemptions, every effort has been made to provide 100% RoHS compliant parts, PCBs and SMT assembly
processes on the LP-100. We recommend the use of standard Pb/Sn alloy solders for assembly of LP-100 kits, mainly for performance
reasons. This is perfectly acceptable under the rules for “own use built equipment (hobbyist)”. Use of lead-free solder is also
permissible, since the PCBs are lead-free, but be aware that special equipment and techniques are required to use lead-free solder,
and PCB rework has a much higher chance of damaging the PCB.
In layman’s terms, the LP-100 is as lead-free as possible without compromising performance or long-term reliability, and builders in
member States are free to assemble an LP-100 with whatever solder they wish.
Hardware Upgrades
Starting with serial #101, the LP-100 uses an upgraded PIC processor, with twice the memory of the previous chip. This allows for
years of firmware development and added features. Any owner of an earlier LP-100 is entitled to a free upgrade to the new processor,
but will need to do an additional calibration to take advantage of the new capabilities. As a convenience to any LP-100 owner, TelePost
will do the chip swap and a free recalibration if the owner returns the LP-100 to TelePost at his shipping expense, and pays for return
shipping ($12 for Fedex Ground insured). Alternatively, TelePost can ship a new processor to the owner in exchange for the old one, or
for a small charge if the owner wishes to keep the old processor as a backup. In this case, it is up to the owner to recalibrate his meter,
and to save and re-program his CAL table into the new chip. For details on chip swapping, send an email to larry@telepostinc.com.
