Repair (?): ICOM IC-R75 that won’t turn on!

Returning home from holidays is not easy. In some sense, I’d like to call it a holiday hangover. You start walking on the wrong side of the road, sleeping at odd hours, and in perpetual need of energy to unpack … Continue reading

Farewell: TBS TBS6925 Professional PCIe Satellite Tuner Card

As a hobbyist with an interest in chasing satellite feeds, my TBS TBS6925 Professional Satellite Tuner Card was my dependable companion. Around AU$250 a piece, I purchased two back in 2011 and two years later, got around to reviewing it. … Continue reading

An Incomplete Repair: BladeRF x40 Software-Defined Radio

Visited: SMPTE 2017 Exhibition Sydney (18 – 21 July)

After returning from my first long-solo-trip, I decided to spend two months “decompressing” and getting ready for my next trip. Part of the reason was so I could attend CeBIT, Vivid Sydney and SMPTE Exhibition. The last time I went … Continue reading

Teardown: Motorola CableComm Series II Cable Access Unit (MM1012A)

I remember when I was very young, peering outside the window and seeing a bunch of workmen and trucks pull up in front of the house. In a short time, they rigged a steel wire between the power poles, then … Continue reading

Canb2016: Part 6 – DAB+, DVB-T, FM Broadcast & Other Radio Scanning

It’s been a busy day of analysis to bring this part of my Canberra trip to a posting, but I suppose, it’s probably good that I’ve done the analysis before the data got too stale. In this post, I will … Continue reading

Canb2016: Part 3 – Exploring the CBRfree WiFi Network

To a geek, having an internet connection is everything. Seeing as my budget conscious hotel didn’t offer free Wi-Fi, I decided I would try my luck and see if I could fix that. They did offer Wi-Fi on a paid-for … Continue reading

Analysis: Freeview Sydney Post-Launch of ABC HD (6-7th Dec 2016)

Yesterday marked the launch of ABC HD, which finally means that Sydney Freeview gets each broadcasters’ main stations in high definition at long last. (EDIT: Actually, not quite true, as 7HD Sydney is still a simulcast of 7mate.) According to … Continue reading

Project: YYDZW BH1417F-based Stereo FM Transmitter Kit

While I was browsing the listings of electronics kits on eBay, I came across this particular stereo FM transmitter kit but I didn’t think much of it. In fact, given the chance to buy it, I passed over it twice. … Continue reading

Project: Sainsmart Forty-9er “3W” 7.023Mhz QRP CW Transceiver Kit

Even though I’m insanely busy, it seems I just can’t help myself when it comes to cheap Chinese kits available on eBay. Of course, having built most of the cheap radio-based kits already, there isn’t really that much to build … Continue reading

Project: CD2003GP+SC3610D FM Receiver w/LCD Alarm Clock (74-108Mhz)

My little “mission” to build random Chinese radio-kits from eBay continues with this rather odd and difficult kit. Unlike the other kits, this is the first to come with an LCD display, but is advertised strangely as FM Radio Kit … Continue reading

Experiment: Sydney WFM Broadcast RDS (TMC, RT+) & ACS Audio

Experiment: Examining Sydney WFM Subcarrier Signals (RDS, ACS)

Project: S66D/E 9018-based AM Radio Kit

If you’ve been wondering about all the random radio kits I’ve posted about recently and had the thought “Gee, that guy must’ve just looked for any cheap radio kits on eBay and bought them all!” You’d be absolutely right. In … Continue reading

Project: 7.023Mhz PIXIE_V3 QRP CW Tranceiver Kit

After I stupidly decided to push the limits on the PIXIE_4.1 and subsequently destroyed its amplification, I wasn’t too concerned. Being the prepared sort, when it comes to low-cost kits, I sometimes buy two in anticipation that maybe some parts … Continue reading

Project: 7.023Mhz PIXIE_4.1 QRP CW Transceiver Kit

Going along the same vein of “radio kits”, this one is a little bit different. This one is a do-it-yourself PIXIE 7.023Mhz QRP transciever intended for amateur (ham) radio morse code (CW) usage. It doesn’t have many specs, but apparently … Continue reading

Project: Paeansonic CF210SP CD9088+CD7642 AM/FM Radio Kit

Wireless Card Whitelists: Failed Attempt at a HP Pavillion dm1-4108AU

After successfully bypassing the whitelist in my Probook 4525s with the help of Dragy, I felt that it was probably worth trying the same technique on my other whitelisted HP, a Pavillion dm1-4108AU. While other pre-patched BIOS for certain dm1s … Continue reading

DIY: Build a 70cm Band Yagi for Amateur Satellite Tracking

It’s been a long time since I’ve chased any amateur satellites. It’s been a long time since I’ve had the time to chase them, and sadly, things have changed. In the seven years or so, satellites I once “knew” as … Continue reading

Getting Started: Nuand BladeRFx40, XB-200 Transverter, Case & SDRSharp

This is one of those posts that I should have compiled and put up a long time ago, but never really got around to. Right now, I probably shouldn’t be blogging (since there are more pressing things to attend to), … Continue reading

Melb2016: DAB+ Scanning & Slideshow Images (Part 10)

In my last post scanning the airwaves in Melbourne, I commented on just how difficult it was to get acceptable FM reception in the hotel. As it turns out, the DAB+ digital radio signals were much easier to receive, and … Continue reading

Melb2016: Scanning the Airwaves from DC to Daylight (Part 9)

Most of my posts so far about my trip to Melbourne have been revolving around photography in a tourist sense, or as a tram-spotter. While some of the observations included some technical aspects, they were all visible and evident if … Continue reading
