- Solid State RadiosI've been thinking about building the LZ1AQ loop amplifier described here: https://www.lz1aq.signacor.com/docs/wsml/wideband-active-sm-loop-antenna.htm . Does anyone have experience with one? It seems to get good reviews and looks not too difficult to construct. I'm trying to lay out the parts placement now in Blender for point-to-point wiring. I have a simpler 2-transistor design (M0AYF) built, but the gain on that antenna is a bit too low for my needs. I hope to use the LZ1AQ antenna in combination with my RTL-SDR + HF upconverter, which has been lying idle for a while.Like
- Crystal RadiosHi All, The diode on my crystal radio is broken, I want to change a new one. I found an old item 1SS86/Hitachi from ebay as below: https://www.ebay.com/itm/134957254013 What is the real performance compare with 1N60P? anybody know about it?Like
- Solid State RadiosI miss the old Radioboard but have found a nice replacement thanks to the talented contributors on this forum. I wanted to post largely to get feedback from others who have the capabilities of building some of these circuits. My first post is a medium wave regenerative receiver using a series regulator as the regenerative oscillator and a shunt regulator as an audio amplifier. The inductor is a standard medium wave ferrite rod tapped inductor from a transistor radio. An unusual attribute of the circuit is that it can function as an acceptable superregen receiver in the medium wave broadcast band. I would look forward to feedback from any others who might be interested in constructing this circuit and hearing of their results.Like
