I found
this interesting kit for an SWR and Power meter from a ham
that builds a couple of kits for Amateur Radio. - Bill W2CQ
Model # GM-102: Graphical HF SWR & Wattmeter
– NEW!
https://wa4mcmkits.com/

- Handles Full Legal Power Across the Full HF Spectrum
Plus 6M– The GM-102 will measure from 1.8MHz to
54MHz. Top range is 2KW full scale.
- Graphical Touch Display – The meter uses a
3.5” TFT display with an integrated resistive touch panel. All
user controls are accessed via the touch panel.
- Peak Hold Capability – The meter comes with
a user-selectable peak hold function that will smooth out the
wild fluctuations when using SSB or CW and display your true
peak power output.
- User Selectable Meter Faces – The user has a
choice of two different meter faces: Traditional Needle, and Bar
Graphs. The needle face can be changed from displaying the
forward power to displaying reflected power. The bar graphs
display both forward and reflected power on the same meter face.
- Three Independent Power Scales – The meter
provides three power scales: 20 Watts full scale, 200 Watts full
scale, and 2000 Watts full scale. The forward and reflected
power scales can be selected independently of each other.
- Always On Digital Display – The forward and
reflected power as well as the VSWR is constantly shown at the
bottom of the meter’s display screen in large numerals for
quick, easy viewing.
- Remote Sensor Unit – The actual sensor unit
is remotely connected to the meter via an inexpensive stereo
cable with 3.5mm plugs on each end. This allows for its
placement in-line without the need to reroute your feedline to
the meter’s operating location.
- Computer Interface – Comes equipped with a
USB interface and companion Windows application for viewing the
meter on your computer screen as well as remotely controlling
all of the meter’s functions. The communications protocol is
published so that the user can create their own application, or
integrate the meter into other 3rd party solutions
such as Node Red.
- Complete Kit is $250.00 plus
shipping.
