Re: OT: Looking for help with Kenwood Handheld
Spot-weld the tabs yourself: AMAZON - Docreate Hand-Held Spot Welder, 5.5KW, $30 73 de Andrew/N5ASE On Tue, May 20, 2025 at 2:59?PM n4buq via <n4buq=[email protected]> wrote:

Re: OT: Looking for help with Kenwood Handheld
Yes - It is a 12mm (maybe 12.5mm) battery. From what I'm seeing, the solder tabs on those are much more in line with the ones on my battery.

Thanks so much for setting me straight on that! Barry - N4BUQ Yeah, I need to measure it. |

Thanks, Barry - N4BUQ GA, CR2032 seems to me is somewhat big, perhaps a CR1220 type fits better. |

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. |
Re: OT: Looking for help with Kenwood Handheld
Barry, If your TH-28A is anything like the Realistic/Radio Shack HTX-202 and HTX-404 HTs, I replaced the internal tabbed 3 volt Lithium cell used in these rigs with a popular CR2032 coin cell and accompanying holder. So now the next time it needs replacement, I can just pop out the old one and insert a new one. No more soldering required. And those CR2032 coin cells are used EVERYWHERE these days. 73 de John, KD2BD |
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

Re: OT: Looking for help with Kenwood Handheld
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, Barry - N4BUQ |
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?

Re: The Drake 2B and its Frequency Spread Limitations
I see the 2B receiver discussed with a 80m switch and crystal position. My 2B has neither. It also has a modified front panel that has a ¡°overlay¡± under the main frequency dial and frequency overlay on some of the frequency log scale. What do I have here and what is the best position to put my 75m crystal (my main band of interest)?

Re: "THE cantenna unveiled!
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
2. Set Up Your Amazon KDP Account
3. Create a New Book Listing
4. Enter Book Details
5. Upload Your Book Content
6. Set Rights and Pricing
7. Publish Your Book
Important Considerations:
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:
2. Utilizing the Same Core Content:
3. Setting Up Each Version in KDP:
4. Linked on the Amazon Product Page:
In essence, publishing on Kindle doesn't automatically create a print book. You need to:
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:
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.
