ICOM IC-9100 Low Power Output Problems

Over the past couple of months, I had noticed some strange power output issues with my IC9100. I don’t use the radio a great deal, but at times, i would see the output power indicator drop over time, or fail to reach peak power, most noticeable on 70 cm FM, but also on HF. I…

Max Howden Crystals

The idiot box does not feature too highly in our household, but today at 9am, Analogue tv was switched off in Melbourne. This was the last location around Australia that analogue tv broadcast services existed, and marked the end of the program to convert Australia to digital tv. I made a couple of videos of…
