Re: Murania is dead after completing build

I found the problem. The solder point of wire going from R3 to C7 cap was loose but not visible to the naked eye. Re-soldered that connection and problem solved. Thanks for the help.

Hi Tommy...Wow...There's not much that can go wrong with the circuit...If you don't even have power to the LED, I would start at the battery and check the voltage through R5...That's a good place to start...If you just follow the DC voltage around the circuit you should find the problem pretty quickly...GL Jim WB2LHP

Murania is dead after completing build
K4VOZ
Hi All,
My Murania radio does not power on anymore, no LED or sound comes up. I finished building the Murania kit and was working fine, I proceeded to do WB2LHP mods and the radio was even better. Now was time to close the case, but the battery didn't fit in correctly. Found R2 and U1 were installed way too high so I bent both of them enough for the battery to fit. Inserted the battery, closed the case, turned radio on and nothing.. no power!! Here's what I did to troubleshoot: verified battery was good, verified R2 and U1 were not short, check for voltage at R5 like in the instructions: no voltage, verified for loose connections: all look good. Any suggestions are welcome. Thanks Tommy K4VOZ

Re: Maurania
Everett Catlin <everettcatlin@...>
Oh Yes I was happy with the Mods. They worked well. The basic Murania did everything I asked it to do without them. I saved the Mod. parts and put it into My Murania Box for future use. Just keeping mine to original specs. I have no problems with it as is. Only problem was a 4 yr old grand daughter over twist tuning cap and bust it. Replaced it and did not glue screw into spacing shaft. Jim they were good and well thought out mods but I mine worked fine here. Look me up on QRZ if you get a chance. Any more Questions just ask.Have a great day. ev Catlin N5MZX

Re: Maurania
John - KD5EJA
I agree, Everett! I've homebrewed and built a lot of kits, but this little AM radio seems to hold some magic in it. I guess it brings back a lot of memories of crystal radios I used to listen to as a kid.
It's strange that you started this thread yesterday. I just so happened to finally getting around to rewinding the ant yesterday while watching college football. I've had the wire sitting on my desk for months, but kept procrastinating doing it! I dozed off after finishing the 15 min job while listening to the Murania. Sweet! 73, John, KD5EJA

Re: Consolidated Murania Mods

Certainly, the wire size will vary the number of turns needed to get the right inductance but there's nothing wrong with experimenting to get the best results...Congratulations!

Never-the-less, it improved the tuning to very close indications on the dial as compared to another old AM receiver I have. I'm happy with that.
