Posted on October 27, 2016 by lui_gough

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 →

Posted on October 21, 2016 by lui_gough

Project: 7.023Mhz PIXIE_V3 QRP CW Tranceiver Kit

Posted on October 2, 2016 by lui_gough

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 →
