Posted on January 30, 2018 by g4hsk

About a year ago I purchased the NooElec Ham It Up v1.3 bare bones HF Up-converter (HFU) to use with their NeSDR SMArt dongle. The plan at that time was to get an SDR-based QRSS Grabber running online 24/7. For … Continue reading →

23cms EME

Posted on June 6, 2017 by g4hsk

The challenge to try EME on another band was made much easier when I heard about the SG-Lab TR1300 transverter. I could see that this could be fairly easily integrated into my existing 2m setup. Things have and continue to … Continue reading →

Having completed the 1.3GHz PA and established that things work well with the transverter (TVTR) and PA located in the shack it was time to tidy things up a bit. I had a spare enclosure that matched the Anglian TVTR and … Continue reading →

Posted on March 7, 2017 by g4hsk

My first opportunity to experience first-hand the advantages of owning a network analyser  was when Charlie, M0PZT kindly brought his MFJ-259 Analyser over and we took a look at a Magnetic Loop antenna that I’d constructed. It was suddenly so very easy … Continue reading →

1.3GHz Transverter – separate TX / RX ports

Posted on March 6, 2017 by g4hsk

The SG-Lab TR1300 transverter continues to impress me. My current setup on 1.3GHz is the TR1300 with Sam, G4DDK’s VLNA and a single 67 element long yagi. The Anglian transverter is used on the 144MHz IF side, both transverters are locked … Continue reading →
