Hermes Lite 2 SDR is a relatively low cost direct conversion software defined amateur radio HF transceiver. This QRP radio has a maximum power output of 5W and

Most of you would have heard of STEM education, meaning Science, Technology, Engineering, and Mathematics. According to Wikipedia, the turnaround of Indian economy with comfortable foreign exchange reserves

Nano VNA tracing showed SWR of 1.213 at 14.680 MHz, for a 20m center fed dipole antenna. That was quite above the 20m amateur radio band. I wish

Universal PCB Prototype Board is somewhat similar to the the Solderless Breadboard, but needs soldering of connections. It can be used for testing out circuits for which a

You would have noted that during my antenna experiments posted earlier, there were several amateur radio bands on which SWR is a bit above the tunable limit of

Just checked the performance of my 80m dipole on 17m as it had tunable SWR on that band with the auto-tuner on my FT-710 radio. I was really

Earlier one end of 80m inverted V dipole was at 3m and other end at 2m from ground and apex at 6m. I was figuring out ways to

That was the nice CW signals from VU2GSM calling CQ on 80m, today morning, at around 6 am local time. Though there was heavy band noise, CW signals

My complex fan dipole was having reasonable SWR on 40, 30, 20, 15, 10 and 6m. I wanted to simplify the antenna a bit and improve performance on

I had found good reception of FM radio stations using my multi-band fan dipole antenna which works for 40, 30, 20, 15, 10 and 6m amateur radio bands.
