Kit status?

Jim Pruitt
 

Is there any guesstimate for the release of the Murania kit?  Might I suggest a little general info about the kit on the groups.io group homepage (or is it called a sub pages since it is a sub group) would be helpful.

Thank you.

Hello Jim
Glad you asked!
We are currently kitting the Murania .
We’re also putting the final touches on the web page.
We’re shooting for a release date on the 4th of July, I hope we make it!!

Keep your eyes on the main reflector 
for the formal announcement.
Thanks for your interest.

Here is my finished Murania

Paul Smith
 

I am listening to our local AM station as I write this. My Murania is one of the Beta build units. It works great. The build was simple as can be and I feel like the kid 60 years ago with my first transistor radio. I am the kitter on this kit and have a BIG bunch bagged up and ready to go to the PO. Watch the reflector and web page for the release. Rumor has it to be released JULY 4. You, your kids and grand kids will love this radio and the time spent spent building it.

I bought my kit at FDIM.  Did a parts check last night and all the parts are there. Am waiting for grand sons next visit to build it.  What a cute radio. May have to build this one for me and order ankther one for him.  Ha!

It would be helpful to include in the instructions which caps are which, ie., 103, 224, 47, etc.  I did check them with a cap checker.  The directions only show the values of the caps but not the designators on each cap.  The caps checked out but some were not close to the listed values so that could be very confusing to a noobie.  I know bypass caps can vary a lot and still work.

Dave, If you check the Pittsburg side of the front panel where the speaker goes is the parts list with designators

Re: Here is my finished Murania

Yes, I did and the print was so small I only recognized things like C2, etc.   I normally would not have even thought of that when checking the parts with the BOM.  This AM I put my lighted loupe on and could finally recognize the ID that identifies with each cap.  It would be very helpful to others to have the 103, 47, etc., that is on each cap placed in the line of those parts on the bill of materials. It has been on previous kits. It was just trying to figure out what was which and I have been using caps and cap equivalent charts, cap meters, for years.  I had to stop and think more.  If I had been in Indiana at my grand kids home I might have not been able to figure it out without all my "helps". Hi!  But, there is a young ham next door to the grand son and he is always willing to help.  There is hope that out of my   six grand kids one will become a ham.  That's not the best odds..... When I was a kid half the kids on the block aspired to ham radio even though only a few of us made it with the help of our scout master. May he forever rest in peace.... What a guy.

Thanks.

Independence from Boredom!

Johnny AC0BQ
 

Good afternoon all:

Hope you are having a Safe and Happy Independence Day! 🇺🇸

I am pleased to announce the latest kit from the 4 sqrp Group.

Talk to anyone who was around during the Sputnik era and he will tell you how exciting it was when the first transistor radios were introduced.  For the first time, you could have a portable radio that could slip into your pocket, and affordable enough that young people could take their music with them anywhere.  The Four-State QRP Group has brought back the thrill of those days gone by with the Murania receiver!  Designed by David Cripe NM0S,  this simple kit is the perfect starter project to get young people interested in our hobby or to bring back those warm memories gained listening to your first portable radio.

 

Find more information at http://4sqrp.com/Murania.php

 

4SQRP is an IRS-recognized 509(a)(2) Public Charity for Scientific Purposes.  All proceeds from kit sales go towards the production of our annual OzarkCon information-sharing and education conference held in early April each year.

Thanks

No hiss from speaker

Paul Cartwright
 

I have finished the audio amplifier portion of the build. I am not able to hear any hiss from the speaker while following the test instructions. The power circuit tested at 1.7 volts. I have double checked the components and connections, including comparing my circuit with the photos on the website. Everything looks correct. Any ideas on how to troubleshoot this problem?

Gm Paul
I built mine a few weeks ago
And that was my outcome as well.
Dave advised me to go ahead with the build.
I did all everything was fine.
I think we may need to update the manual.

Re: No hiss from speaker

Thanks for the reply Johnny.  I did go ahead and finish it last night. It worked perfectly even though I did not get the hiss like the manual said.  

Interestingly, I had put the continuity tester across the primary coil of the transformer and heard a hiss from the speaker. So, I knew that the transformer through the speaker was wired correctly.

Good going Paul.  Can you receive WHO 1040, or WMT 600 ?  It will be good to have your rcvr as a demo unit for the upcoming Expo.

More Murania Mods

Jim WB2LHP in MI <jmarco1955@...>
 

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 regarding the change in use of R3, change R2 from 1K to 2.7K...

Frequency coverage and dial mapping...

Increase L1 from 37 turns to 51 turns...Remove C8...This centers the frequency coverage and makes the dial tracking spot on...

Overall Performance...

The audio is now crystal clear...Tuning is sharper...The change to L1 may not be necessary or important to you...It is offered as an option to you...The change to R2 is critical, in my opinion...Your mileage may vary and these mods are made at your own peril, but are not hazardous...

The Murania radio is an outstanding kit and highly recommended...Please email me with any questions...73 Jim WB2LHP in MI
