It is finally summertime in Northern Europe! This however means my workshop/studio gets to over 30 degrees Celsius; and some equipment such as these analogue telephone adapters runs hot (and can thus go defective quicker). So I added a ventilator fan and a local 12V power supply recovered from obsolete/faulty equipment 🙂

I use the SeaTTY software to decode 147.5 KHz RTTY transmissions (this old TV is displaying a VNC connection to a newer laptop in the other room, which has far less QRM (interference) than my workshop/studio full of computers…

Currently I only use an indoor random wire antenna and the radio receiver and laptop or netbook are powered by accus to keep out noise from the mains cables (there is plenty)
