Re: [Elecraft] K1 Discontinued
Luckily to have mine K1, bought this year. I intended to buy another one by the end of this year. Now I have to safely keep it as a jewel! https://www.flickr.com/photos/roney/34754819981/ Great little rig... 73 de PY1ZB On Thu, Aug 31, 2017 at 3:00 PM, James Bennett <w6...@me.com> wrote: > Guys - I’m about to hit the magic “70” mark and have been using +250 > readers for quite a while.

Re: [Elecraft] K1 - VFO frequency range
Hello Mike and Cameron, I appreciate your tips. I adjusted the L1 inductor, getting 3.500,3 mhz and 20.098,2 mhz on VFO. That was perfect to me. (updating Cameron about the email) So I moved the rig to another place and used another PSU (first using a 12,4v, and after using a 13.8v PSU) I noticed that this minimum frequency changed to 3.501,2 mhz. No problem about that. Thanks and 73, de PY1ZB, Roney On Wed, May 24, 2017 at 11:56 PM, Cameron Francey < cameronfranceyut...@hotmail.com> wrote: > Just as an additional note.

[Elecraft] K1 - 2 band, is possible to add another 2 band PCB ?
Hello, now that my Rig is ready, I want to ask something that wasn't clear when I bought it. In Elecraft website, there is a "*KFL1-2 <http://www.elecraft.com/k1_page.htm#K1%20Options> Additional 2 Band Module*"; I did not buy it, because I still don't know if it works. I already have B1 as 3.500 mhz I already have B2 as 21.000 mhz If I buy and add the second 2 band module, can I have all together 4 bands in my Rig ? (Like adding B3 as 14.000 mhz, and B4 as 7.000 mhz) Thanks Roney PY1ZB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] K1 - VFO frequency range
Hello, I just finished all tests and adjustments in my K1. It works great. I have 2 filter band as 80m and 15m. It's transmitting and receiving very well. I followed all tests in: VFO Range Test (Page 38): VFO knob fully clockwise = 3.007 khz VFO knob fully counterclockwise = 3.091 khz VFO range = 84 khz So I did Band Assignments (Page 39), etc, etc. When seeing each band, my real ranges are: 80m: 3.493,8 to 3.577,6 mhz 15m: 20.990,9 to 21.074,6 mhz I did not understand how to adjust these low and high limits. Should I change some inductor turns ? or is there any menu adjust for these limits ?

[Elecraft] K1 and DMM resistance checks
Hello, I'm just building my first K1. Everything is going right, I had already build the filter board, the front panel, and now in main board. I have a question about resistance checks using DMM: - Every time when the manual says that in some point the resistance must be > 100K, my multimeter shows 1, just like there was no resistance. Is that right ? For all other resistance checks in specific values or ranges, it's working as expected. I just need to solve this doubt in order to proceed. (now I'm on page 29 from manual) Thanks and 73 Roney Monte (PY1ZB) __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
