Review, Teardown: Unbranded AC1200 Dual-Band USB 3.0 Wi-Fi Adapter
In the short span of about two decades, Wi-Fi went from being a luxury that you would consider a limited alternative to a cabled Ethernet connection, useful for mobile devices only, to something resembling a near-replacement for the cabled Ethernet … Continue reading

Salvage, Teardown: DingTong DT-98 8W 403-470Mhz Handheld Transceiver

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)

Analysis: Freeview Sydney (18 April 2017) after SBS moves to HD MPEG-4
While I was on holidays, the DVB-T digital TV stations at home were undergoing the last of a series of long-anticipated changes. On 8th April 2017, SBS followed the lead of the other broadcasters and finally converted over to MPEG-4 … Continue reading

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

Radio: DAB+ in Sydney (25 Nov 2016) – Service Info & Slideshows

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)
When I was still in school, I can remember my Dad buying a “special radio” from a broadcaster to listen to some ethnic radio broadcasts. The radio was quite expensive, and it looked and felt just like a regular portable … Continue reading
Project: S66D/E 9018-based AM Radio Kit

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

Review, Tested: Generic USB FM Transmitter (FM_MIC_V5.0.9)

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

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)

Freeview Update: 7flix “now available on more TVs”

Failed: Cheap and Nasty SMA Right-Angle Adapter (& Site Update)
