I have been hearing about the low noise level for loop antennas for a long time and always wanted to try out one. Two problems faced by me

One of the important uses of transistors in electronic circuits is as an amplifier, though there are other uses like in switching, oscillators and frequency changers. Amplifiers are

My earlier attempts at checking in to morning SSB HF nets on CW were unsuccessful as I could not setup my FT-710 radio to TX on CW while

Though I have worked several stations from Europe during the past 10 months with my new FT-710 radio, I had to wait for the CQWW DX Contest 2024

Unlike direct current, alternating current reverses direction of flow periodically. Rectifier is a device which converts alternating current to direct current. It does this by cutting off one

In spite of a solar flare yesterday and band predictions being just ‘fair’ as per the Solar Terrestrial Data on QRZ.COM, 20m band is open here early morning.

Electronic components like resistors, capacitors and inductors can be connected together in series or parallel. Components connected in series are connected along a single electrical path and same

2024 CQ World-Wide DX Contest for SSB mode starts at 00:00:00 UTC Saturday, 26th October 2024 and ends at 23:59:59 UTC Sunday, 27th October 2024. Even though I

Phase of a wave is the angular displacement of a sinusoid from a reference point or time. Phase in the context of alternating current can be considered as
