I have been hearing my friends giving spectrum spread reports when other friends were testing homebrew linear amplifiers. Yesterday VU2MIE, who is also using an FT-710 radio told
In RF engineering, a binocular combiner (often called a binocular transformer combiner) is a passive device used to sum the power from two separate linear amplifiers into a single output while
The height of your inverted V antenna is crucial because it significantly affects the antenna’s radiation pattern (where the signal goes) and its feedpoint impedance (which affects SWR).
That’s a great question for an amateur radio operator! The length of a half-wave dipole antenna (which is what an inverted V is based on) is primarily determined
Here are a pair of my new RG58 coaxial cables, both 15m long. One has pre-crimped PL259 connector at one end only while the other has pre-crimped PL259
ES25N Stud-mount rectifier diode Average Forward Current (If(AV)): 25APeak Reverse Voltage (VRRM): 400V to 1600V (depending on the specific voltage variant, e.g., ES25N-04 for 400V, ES25N-16 for 1600V)Maximum
Yesterday’s technical roundtable on 7135 kHz was joined by VU3LKZ, VU3LKT, VU3ATD, VU23KM andVU2LSK. Main discussion centered around waterproofing of antenna cable joints. I had mentioned that I
This is the screen of battery management system of my Lithium Iron Phosphate (LiFePO4) Battery. It has a rated capacity of 105 Ah and nominal voltage of 12.8V.
Allocation in the 160 meter band for radio amateurs in India according to the National Frequency Allocation Plan 2022 is 1 800-1 825 kHz. In some other regions,
Resonant antennas are tuned to specific frequencies, efficient at those points, have pure resistance but narrow bandwidth. Non-resonant antennas work across wide bands (traveling waves), need matching networks
