Building Alfred P. Morgan’s “A More Selective Crystal Receiver”

 


As I’ve been seeing a lot of new membership requests on my Facebook Crystal Radio DX group indicating that they wish to build a crystal receiver, I’ve been examining some simple inexpensive circuits that should work well for local reception and possibly even to hear some skywave DX signals.
 
Since I’ve always wanted to build Alfred P. Morgan’s ‘A More Selective Crystal Receiver’ from his second ‘Boy’s Book of Radio’ ever since first seeing it at around age 10, I chose this as a start.
 
How did it Morgan’s design work? Could it hear all of my 15 locals and separate them? Was it a DX machine?
 
I invite you to read about the whole process on my web page, just published today:

Taking my moms advice…….

 


Once moved out from home and on my own, I always remembered what my mom told me regarding credit cards. She said it was always good to have one as a just in case emergency BUT put it in a zip lock bag, fill it with water and put it in the freezer. This way if you are tempted to use the card you have to wait for it to thaw out and by then you may feel what you really "needed" was not a need but a want. 


The bottom line to that way of thinking is sometimes you have to take time to think about what you're going to purchase. Recently I did not use the frozen credit card theory but I am glad I took time to think. I had an email notice come to me informing me that my RSGB membership was coming to an end. The renewal was 70 British pounds which converted to about 120.00 Canadian dollars. ( I was just adding an RSGB link and noticed the fee was not 73.00 pounds which is 124.00 Canadian...NOT) That seemed very steep for me considering the main reason for my membership is the read Radcom magazine. The bottom line for me was that it was way too pricey so I was considering another radio magazine. 


I was looking at CQ magazine as in the past I did have a subscription from them but even then (about 8 years ago) the subscription missed issues and other times issues were late. I decided to wait it out and let the RSGB membership expire and then think about the next move. Kinda like letting the credit card thaw on the counter before I jumped.


Well CQ magazine does not seem to be doing well and online chatter has not been glowing. I just recently checked and their website is no longer loading. There was a statement from CQ saying they have "temporarily " suspended the magazine. In my humble opinion that is never a good sign. I have also read recently of those who just purchased a 1 or more year subscription and so far have received nothing. As a sideline, I feel CQ magazine should refund those who just purchased a subscription but we shall see. 


Well, I am glad that I let the credit card thaw on the counter before I jumped and made a subscription purchase to CQ magazine. To be upfront I will not be taking my chances on this company until it can show stability for at least 2024 without issue. Until then I will have saved some money and I can throw the credit card back in the freezer.

New Page On VE7SL Radio Notebook!



Thanks to May (VA7MAY) and Mark (VA7MM) spending the time to scan my 630m QSL card collection, I have now been able to complete their work by posting a dedicated page for the cards.

If you've ever wondered what can be worked on this 'below the broadcast band' MF amateur band, then viewing the cards and reading their comments may give you some insight into its character.

                              The new page can be found here.

Joining the ARDC Board

Amateur Radio Digital Communications (ARDC) is a unique organization in the world of amateur radio. ARDC is organized as a foundation with two main roles: management of 44Net and a grants program. The foundation has assets a bit over $100M and funds grants roughly at the $5M level each year. (These are very rough numbers. For the specifics, take a look at the audited financial statements.)

I started out serving on the Grants Advisory Committee and told my ARDC story here:

What’s This ARDC Grant Thing?

I am honored to be asked to join the ARDC Board of Directors and I look forward to serving in that volunteer role. See the ARDC announcement here:

Bob Witte, K0NR, joins ARDC’s Board of Directors

I am new to the Board but have worked with them as a member of the Grants Advisory Committee. I can tell you that they are a great bunch of people, all motivated to do the best for amateur radio and digital communications. ARDC also has a small paid staff that makes things happen on a daily basis, all great folks to work with.

If you have feedback or suggestions for ARDC, my door (and inbox [email protected]) is always open. If you want to apply for a grant, working directly with the ARDC staff is best. The grant process is described well here.
