Re: OT: Looking for help with Kenwood Handheld
I didn't know that could be done as a service like that.? We have a Batteries Plus but not sure if they'd do that.
Thanks for the tip! Barry - N4BUQ
If you have a Batteries-Plus, or Batteries & Bulbs store near you, they might have one. They have the ability to spot-weld tabs on about any battery.
This is the only amateur radio group of which I'm a member so I'm looking for a bit of help.? Is there an appropriate group for older Kenwood hand-helds?
I have a TH-28A that needs an internal lithium battery and am having no luck finding a suitable replacement.? If someone can point me to a group or, even better, point me to a source for those batteries, I would appreciate it.
Note that I can find all sorts of lithium coin cells with solder tabs but none of the ones I find match the configuration of the one in my TH-28A.
Thanks,

Re: OT: Looking for help with Kenwood Handheld
I've seen some of those but most of them have rather larger and wider-spaced solder tabs.? I'm attaching a picture of what's in my radio.? I might be able to trim the tabs as it appears that may have been what was done to these from the factory.? I'm pretty sure it's a CR-2032 but the part number in the service manual doesn't show up anywhere I've looked.
Thanks, Barry - N4BUQ
I found one for my FT-470 on Amazon. Gamers have lots of devices with these sorts of batteries.?

Re: The Drake 2B and its Frequency Spread Limitations
Like Mike says, no crystal needed on 80.
?
The 2B is an 80 meter receiver with a crystal controlled converter on the front end for the other bands.
80 meters should be the first position on the left of the bandswitch (counterclockwise).

What does your overlay look like?

Looking at the photos that I posted some time ago at /g/DRAKE-RADIO/album?id=252836 it looks like the wires are: White - Audio Red - PTT Shield - audio ground Black - PTT return (ground) Connect black and shield together. This was for a time the "standard" color code for USA manufactured microphones, although red and black could often be reversed with no ill effect.

With mine it is not a matter of overage, but of leakage. I don't think these paint cans contain oil very well. The one I have with oil has been sitting in the cake box cover drip tray for well over a year and I have close to an inch of oil accumulated. And I have never put RF to it.

Re: "I Never Should Have Gotten Rid Of......
No need to worry about printing quantity minimums:
A.? GeminiAI: How to Publish a Book Via Print-On-Demand on Amazon
To publish a
book via print-on-demand (POD) on Amazon, you'll primarily use Amazon
Kindle Direct Publishing (KDP). Here's a comprehensive guide:
1. Prepare Your Book
Manuscript:
Ensure your book is professionally edited and formatted according to
KDP's guidelines. They accept various file formats, but EPUB
is recommended for ebooks and PDF for print books.
Pay close attention to trim size, margins, and bleed settings for
the print version.
Cover Design:
Create a compelling cover that meets Amazon's specifications for
both ebook and print. You'll need a front cover for the ebook and a
full wrap-around cover (front, spine, and back) for the print book
as a single PDF. ISBN: For print books, you'll need an ISBN.
You can use your own or obtain a free one from KDP, but note that a
KDP-assigned ISBN can only be used on Amazon. Ebooks do not require
an ISBN.
2. Set Up Your Amazon
KDP Account
Go to
and sign in with your existing Amazon account or create a new one.
Complete your account information, including payment details
and tax information.
3. Create a New Book
Listing
Once logged in, go to your
Bookshelf.
Click the "+ Create"
button.
Choose either "+ Kindle eBook" or
"+ Paperback" (or both).
4. Enter Book Details
Language: Select
the primary language of your book.
Book Title and Subtitle:
Enter the title and subtitle exactly as they appear on your cover.
Series (Optional):
If your book is part of a series, enter the series name and volume
number.
Author: Enter
your name or pen name. You can add contributors if needed.
Description:
Write a compelling description of your book (up to 4,000
characters). Use formatting like bold and italics to highlight key
points. Publishing Rights:
Indicate whether you own the copyright and hold the necessary
publishing rights.
Keywords: Enter
relevant keywords that readers might use to search for your book (up
to seven). Categories:
Choose up to two categories and subcategories that best describe
your book.
Adult Content: Indicate if your book
contains adult content.
5. Upload Your Book
Content
eBook: Upload
your manuscript file (preferably in EPUB format). Print Book:
Upload your formatted manuscript
file (in PDF format). Specify the print options,
including trim size, paper color (white or cream), and bleed
settings.
Book Cover:
Upload your cover file (JPG or TIFF for ebook, PDF for print). You
can either upload a file you've created or use KDP's Cover Creator
tool. Book Preview: Use the online previewer to
review your ebook and print book to ensure everything looks correct
before publishing.
6. Set Rights and
Pricing
Territories:
Choose where you want your book to be available for sale. You can
select "All territories (worldwide rights)" or specify
individual regions. Pricing:
eBook: Set your
list price. You can choose between a 35% or 70% royalty option,
each with different pricing requirements.
Print Book:
Amazon will calculate the printing cost based on your book's
specifications (page count, ink type). You'll then set your list
price, ensuring it's high enough to cover the printing costs and
your desired royalty. KDP offers a 60% royalty rate for print
books. Note that starting June 10, 2025, the royalty rate for print
books priced below certain thresholds (e.g., $9.99 USD) will change
to 50%.
KDP Select (eBook only, optional): If you
choose to enroll your ebook in KDP Select, your ebook will be
exclusive to Amazon for 90 days, but you'll gain access to
additional promotional tools and earn royalties from Kindle
Unlimited page reads.
7. Publish Your Book
Once you've completed all the
steps and are satisfied with the preview, click the "Publish
Your Kindle eBook" or "Publish Your
Paperback" button.
Your book will then go through a
review process by Amazon, which typically takes up to 72 hours. Once approved, your book will be available for sale on
Amazon.
Important
Considerations:
Print Quality:
Consider ordering a proof copy of your print book before making it
available for sale to ensure the print quality and formatting meet
your expectations.
Marketing: After
publishing, you'll need to market your book to reach readers. Amazon
offers advertising options, and you can also use social media, your
website, and other promotional strategies. Royalties and Payments:
You'll earn royalties on each book sold. KDP provides reports on
your sales, and payments are typically made monthly. Content Guidelines: Ensure your book content
and cover comply with Amazon's content guidelines to avoid rejection
or removal.
By following these steps, you can successfully publish your book
via print-on-demand on Amazon and reach a global audience. Good luck!
B.? GeminiAI:
How Does Publishing
a Book on Kindle Translate
to Print-On-Demand on Amazon?
Publishing a book on Kindle (as an ebook) and making it available
as a Print-On-Demand (POD) paperback or hardcover on Amazon are two
distinct but interconnected processes within the Amazon Kindle Direct
Publishing (KDP) platform. They don't automatically "translate"
in the sense of a single upload magically creating both formats, but
KDP facilitates creating both from the same core content. Here's how it works: 1. Separate Creation and Uploads:
Kindle eBook: You
upload your manuscript formatted as an ebook (ideally in EPUB
format) and a separate ebook cover file. Amazon then converts this
into the Kindle format (.mobi or .azw).
Print-On-Demand (Paperback/Hardcover): To
offer a print version, you need to create and upload a separate,
properly formatted print-ready PDF file for the
interior of your book. This requires careful attention to trim size,
margins, bleed (if applicable), and pagination. You also need to
upload a separate full-wrap cover PDF that includes
the front, spine (with accurate width based on page count), and back
cover. 2. Utilizing the Same Core Content:
While the files and formatting are
different, the underlying text of your book will likely be the same
for both the ebook and print versions. You'll typically work from
the same manuscript but format it differently for each output.
The cover design might share elements, but the print cover
needs to be a complete wrap-around design, unlike the front-only
ebook cover. 3. Setting Up Each Version in KDP:
Within your KDP Bookshelf, you
will create two separate book listings: one for the
Kindle eBook and one for the Paperback (and potentially another for
Hardcover if you choose that option).
For each listing, you'll go
through a similar process of entering book details (title, author,
description, keywords, categories), but you will upload the specific
files relevant to that format (EPUB for ebook, PDF for print
interior and cover).
You will also set separate pricing and distribution options
for the ebook and print versions. Print book pricing needs to
account for printing costs.
4. Linked on the Amazon Product Page:
Once both the ebook and print versions are published, Amazon
typically links them on the same product page.
Readers will see options to purchase the book in Kindle format,
paperback, or hardcover (if available). This allows customers to
choose their preferred format. In essence, publishing on Kindle doesn't automatically
create a print book. You need to:
Format your manuscript
specifically for print.
Design a full-wrap cover
for the print version.
Create a separate book
listing for the paperback/hardcover on KDP.
Upload the print-ready interior and cover files.
Think of it as preparing two different products (an ebook file and
a print-ready file) from the same source material and then managing
them as separate listings on the KDP platform, which Amazon then
conveniently links for the customer. Key Differences and Considerations:
File Formats:
EPUB for ebook, PDF for print.
Cover Design:
Front-only for ebook, full-wrap for print. Formatting: Ebook
formatting is reflowable, while print formatting is fixed.
ISBN: Not
required for ebooks, but usually necessary for print books. You can
get a free one from KDP, but it's tied to Amazon.
Printing Costs:
Apply to print books and affect your royalties. Royalties: Different royalty structures for
ebooks (35% or 70% options with specific pricing) and print books
(60% minus printing costs, changing to 50% for lower-priced books
starting June 10, 2025).
By managing both the Kindle eBook and the Print-On-Demand versions
through your KDP account, you can offer your book in multiple formats
to cater to a wider audience. Let us know when your book is available on Amazon! :-) 73 de Andrew/N5ASE PS:? If the original text files aren't available, consider recovering the text via OCR. -0-

Anyone interested in the "Life and Times of Heathkit" should pick up a book titled "Heath Nostalgia."? It's good reading and details the company from it's meager start making airplane kits.?
I went straight to the source on this one after discovering how expensive old copies are now. The book was written by K8TP, Terry Perdue. It's now long out of print and he says he would have to buy a thousand copies to put it back in print, so he won't.
?
Terry also compiled a CD of 1000s of photos he collected at Heathkit, and then he added a PDF of the book to the CD. The volume is titled "Heathkit: The Early Years". I asked Terry if the CD was still available from him, and here's his response:
?
"Please let anyone who would like one know that they can use PayPal or send me a check at
18617 - 65th Court NE
Kenmore, WA 98028-7920
and I will put the CD in the mail the same day."
?
$15 is his price postpaid, and Terry is at k8tp@... if you want to send PayPal instead of check.

If the moderators want to cross-post this over to the Heathkit list, please do so. Dave

In looking at your photo again, I see an unknown device up above the chassis, where the calibrator option is

If you can get this working, it will be handy for debugging.
