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
An antenna tuner affects the heating and power handling capability of the toroid in a balun or unun by altering the impedance match and SWR between the tuner
Today was a very fruitful day for the technical roundtable on 7135 kHz. Discussion started off with VU23KM who had recently upgraded from VU32KM in a short period
Yesterday VU2JN Technical Roundtable on 7135 kHz was listened to by VU3CDK on VU3TBU WebSDR while in transit! He suggested simultaneous 20/40m operations and listening on WebSDR as
The power handling capacity of a 1:1 current balun on a toroid is primarily determined by its ability to manage heat dissipation and avoid magnetic core saturation. The
As scheduled yesterday, VU2MV and myself joined on 7035 kHz at around 745 am, which was the roundtable frequency with VU2JN and others four decades back. VU2JN was
