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 s

Everett. Were you not happy with the mods?

Same here. Every day.

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!

Great news Johnny!

Glad to hear you are pleased with the mods John... In my case, I still had the leftover wire from the build...I just soldered the wire on and would the coil out to 61 turns...I had the help of an indu

Thanks John...Let me know if you need any assistance...Jim WB2LHP

I've been asked to re-post my list of mods to the Murania receiver...This is the updated list with corrections to previous typos...Please feel free to ask any questions...Jim WB2LHP Detector Gain Cont

GM Dave...You are much closer to the towers for WCCW and WTCM than I am...I'm off of Goodrick Road between Cedar Run and M-72...You are experiencing the same problem I initially had...The L1 coil as w

GM Dave...I think you may have misunderstood my tuning/gain method...Let me rephrase... In general with the Murania, as you go up in frequency, you will need more gain...That's just a function of the

I have distant stations at night that sound like locals...It's not about how far away they are but how strong...Weaker signals will need more gain but you'll get the feel for it quickly... For your gr

GM Dave...The original circuit worked well if you were not in the presence of strong stations...I have 50kW and 15kW stations in my back yard so I'm completely swamped with RF here...When you say you

Hi Dave...My two resistor mods will absolutely improve the performance of the Murania...The Changes to L1 and C9 are NOT necessary unless you're fussy like me about the frequency coverage... Let me kn

After some experiments tonight, it seems the TA7642 is optimized for the AM broadcast band frequencies...Any stations heard on 49 meters were extremely faint...I would recommend the Ozark Patrol for s

Will...The coil should be 61 turns total...Jim WB2LHP

So, of course, I made a mistake...Fat fingers and old eyes...I mistyped the total number of turns for L1...It is 61 turns, not 51 turns...Sorry for the error...Jim WB2LHP

Here is a simple mod that will produce better performance from the very fine Murania radio...It is completely reversible and requires no hacking of the radio... I live 5 miles from a 50kW AM station w

Here are some additional mods for the Murania radio...These are easy to do and are completely reversible without hacking the radio... Reduced audio distortion... In addition to my previous post regard
