20dB – what a massive loss

Posted on:

A couple of subscribers requested an update on the minimalist urban station development. I guess primarily due to their interest in SunSDR2DX – a 100W HF/6/2m SDR transceiver and it’s performance in RF polluted urban environment. After two weeks of spending a couple of hours a day on air, I am pleased to report that the radio is performing flawlessly. There is one particular aspect that has impressed me more than any other: it’s stability […]

As we always say, amateur radio is a multifaceted hobby. It offers something to everyone, and covers a very wide range of activates. From serious DXing, even more serious contesting, technical advancement, home brewing, outdoors operation,  microwave and satellite communication – even bouncing signals off the Moon – to a casual interaction with amateurs for no other purpose than to say hello. And whichever activity you chose to participate in, you are free to set […]

What would Sherwood invest in?

“Hi, Just a thought – something to add in your next advert regarding the IC-8600. ‘Today, we’ve just received IC-R8600 which has been out of stock for almost a year. If you are an SWL looking for one, you know what we’ve got. And if you are asking yourself ‘why would anyone in the world pay that much for just a receiver…?’ Maybe because it’s also the highest performing wideband receiver according to the internationally […]

IC-R8600

If you are a full licensed amateur, surely, at some point in time you’ve troubled yourself with a strange dilemma: why would anyone pay $4,000 for a receiver, when for less than half, he could have had a receiver AND transmitter, in the same box? Makes no sense, whatsoever. To unpack this mystery would take pages and hours. Let’s just say that the answer lies in the fact that SWLs (short wave listeners) are a […]

Minimalist urban setup, part 4.

Posted on:

A quick recap: the major challenge in an urban environment is signal reception. Due to heavy city RF pollution – the result of hundreds of electrical devices in close proximity to a receiving antenna – only the strongest signals are audible and decodable. The best way to think of it: the difference between the number of stars visible from within the city versus the majestic night sky in the middle of a desert. The bad […]

Setting up an urban minimalistic station: Part 3 By the time I got home, it was already quite late. But I couldn’t wait to power up my SunSDR for the first time. The burning question was THE most important question of all: how many signals – if any – are protruding through the noise ceiling? Yes, the urban noise ceiling, not the countryside noise floor. Before that, the shack had to be massively decluttered. Finding […]

Every project worth doing will take twice as long as originally anticipated. And be double the original estimate. After yet another trip to Bunnings (UV resistant rope and more stainless steel bolts, $70) the antenna was finally ready to go. Feed point: 8m above the ground, total length 13m. A lightweight but sturdy construction – an easy one man job. The main thing is to keep the antenna invisible to the neighbours. Not completely invisible, […]

Setting up a minimalistic urban station

Posted on:

Three years ago, I took down my SteppIR and said goodbye to playing radios from Sydney. The noise was simply unbearable, especially on low bands. However, what broke the camels back was not the RF interference, but the interference from both neighbours who after many years of not paying attention to my antenna tower and 3 element beam all of a sudden became aggressive towards my hobby, threatening ‘council action’ and nasty litigation. I had enough […]

Full steam ahead!

This morning I had a meeting with Mr. Hacko. A brief one, with just one item on the agenda: my plans for DXing for 2024. And the plan is simple: to become the number one ICOM dealer by Christmas and to grow this mailing list to 3,000 subscribers. “Ambitious, but possible. Who is your competition and what resources do you need to make this happen?” – he asked. I’ve done my research: my only competitors […]
