Re: [Elecraft] SPKR+PH fault

Hi Paul, I have the same issue. It just happened some time ago so I traced the PH_SW signal down to U8 pin#9. PH_SW acts as intended so either U8 input is faulty or it is in FW. Jan SM6TUW Paul Ormandy ZL4PW wrote Hi all, Further to the earlier issue... i.e. my K3 is in SPKR+PH - On

[Elecraft] Shematics update

Elecraft Design Team! The K3 is well documented in shematics up to june 2010 but there are some new kits and options as K144XV PLL, K3XREF and KPA500 not yet shown to us. Will these schematics be released ? I enjoy reading shematics of the Elecraft kits and feel it is as an important part of the

Re: [Elecraft] KPA500

Eric, I have some questions: 1. What is the total shipping weight for a KPA500 kit? (for shipping cost estimation.) The transformer is probably the main contributor. 2. Do you have any plans to ship a kit that can be sourced by a customer power supply or is the built PS tightly

Will this new firmware work with the anticipated K144XV option module ? By the way , what is the status of the option module ? 73, Jan -- View this message in context:

Wayne, David, my question was unclear: I was referring to the optional PCB to be installed inside the K144XV on top of the tranverter PCB. The K144XV I already have. I am looking forward to the PLL function for locking the 116 MHz VCXO to the 49.380MHz. Is that project ongoing? Jan -- View this

Re: [Elecraft] Clock Accuracy

I consulted the data sheet for the clock circuit PCF8563T (U16 in the K3 circuit diagram ) You can adjust the average deviation over one year to less than +- 5 minutes. Adjustment of one capacitior (C60) is required though. http://www.nxp.com/acrobat_download/datasheets/PCF8563_6.pdf Jan --

[Elecraft] New K3 shematic

Just found the june 2020 K3 shematic. I´m looking forward to some nice reading...K144XV is included. Thanks Elecraft! Jan -- View this message in context: http://elecraft.365791.n2.nabble.com/New-K3-shematic-tp5195072p5195072.html Sent from the Elecraft mailing list archive at Nabble.com.

Re: [Elecraft] KREF3 External Reference card

Hi Someone pointed out that we all have different 49 MHz oscillators. I guess that many K3 owners have TCXO and thus no input for the voltage control i.e. VCXO. This pin is indicated in the KREF3 shematic as pin 1 (VCTRL) of Z1. My KTCXO3-1 did not have this pin and could not be used vith the
