Re: [Elecraft] [K2] K60XV - No longer available?
Bill, It's not just a matter of deciding to sell the thing without a few parts. Manufacturing and distributing hardware, whether pre-assembled or in kit form, takes a LOT of work. Check out this video from Dave Jones at the EEVBlog on the economics of manufacturing your own hardware: https://youtu.be/UwrkfHadeQQ There's also a long thread on his forum: https://www.eevblog.com/forum/blog/eevblog-887-the-economics-of-selling-hardware/ I strongly recommend Dave's Youtube channel and his forum for information about electronics. If you're in the industry, maybe you've already run into it. I hope the video I linked helps clarify why it's not just a matter of putting out a kit or product "without the 60m parts". (I wouldn't even want to know the product liability side of distributing a product missing some parts because they're no longer available. That sounds like a lawsuit waiting to happen.) 73, Gwen, NG3P (who in no way works for Elecraft, and is just putting in her 2 cents worth) On Wed, Sep 11, 2019 at 6:21 PM Bill Coleman wrote: > Here’s a radical idea.

Re: [Elecraft] [K2] K60XV - No longer available?
There are some thing the universe does not allow. Driving faster than the speed of light is one, discarding angular momentum in an isolated system is another. So is "A small cost, small design change." I lost count of the number of customers who said, "How come so much, it's only a few lines of code, right?" 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/11/2019 4:43 PM, Don Wilhelm wrote: Bill, Before this "idea" gets too far, let's look at the practical side of it.

Re: [Elecraft] Width adjustment of Manual Notch Filter on K3S
A better technique would have been to turn off the AGC off and reduce the RF gain. I do this for FT8 and it works quite well. -de John NI0K Ken Bandy, KJ9B wrote on 9/11/2019 4:02 PM: Hello.

[Elecraft] Width adjustment of Manual Notch Filter on K3S
Hello. Is it possible to manually adjust anything other than the position of the notch filter on the K3S. I recently was working FT8, when a ham relatively close to me was desensing my receiver when working FT8 on the same band. I was able to notch him out by manually setting the filter, but it seems like a pretty wide notch, especially for FT8, and was wondering if it was possible to adjust the width of the notch. I didn't see anything in the manual regarding adjustment of the width.
