Power And Swr Meter Arduino | May 18, 2020 · the experiment: Mar 07, 2021 · the arduino can power down the system anytime by setting digital output pin 7 to low, thus switching off q2 and q1. In this experiment were going to explore the use of a 1:64 matching auto transformer on the end fed long wire antenna. Mar 24, 2018 · the same circuits can be used for the rf power coupler and the ad8307 as in the original power and swr meter project, however a few new builds are shown below. Qrpguys 10/20/30db 50ω switched attenuator;
I have read a lot of post on the internet regarding the great performance off a end fed long wire antenna of with a 1:50 / 1:64 matching network. Qrpguys digital power/swr meter w/dummy load; Mar 07, 2021 · the arduino can power down the system anytime by setting digital output pin 7 to low, thus switching off q2 and q1. The swr meter should show a standing wave ratio of approximately 1:1.5 or lower. Qrpguys 10/20/30db 50ω switched attenuator;
Usually the swr meter does show some reflected power with this test. I have read a lot of post on the internet regarding the great performance off a end fed long wire antenna of with a 1:50 / 1:64 matching network. The code can be used with a full blown arduino board or an avr microcontroller chip can be programmed and used directly in a circuit.… Split, single, virtual ground, etc. In theory the arduino could directly drive the gate of the fet q1 without using q2 as a buffer; See appropriate #defines in the pswr_x.h file, included in the source code. However this would result in approximately 500 µa of idle current constantly flowing through r4 into pin 7 while the system is turned. And this is only the beginning! Qrpguys digital power/swr meter w/dummy load; Alternately, a coupler with diode detectors can also be used.

Qrpguys digital power/swr meter w/dummy load;
Use an arduino to draw pictures on an oscilloscope using xy mode #79: Mar 08, 2021 · adjust and test rf matching networks and rf amplifiers without applying power. See appropriate #defines in the pswr_x.h file, included in the source code. Qrpguys 10/20/30db 50ω switched attenuator; The swr meter should show a standing wave ratio of approximately 1:1.5 or lower. And this is only the beginning! 12w dummy load / power meter; Usually the swr meter does show some reflected power with this test. It's also possible to test with a half wavelength of wire. May 18, 2020 · the experiment: May 08, 2021 · adjust your antenna tuner for a perfect 1:1 match without creating qrm.
