[Elecraft] KSYN3A dead?
Hi everyone, today I turned on my K3 and I can't receive any signal in any band. Then I tried to tune and power out is 0.0w. My k3 has two ksyn3a, but in the menu I see DDS FRQ and VCO MD; also tapping DISP I see PLL1 and PLL2 (with value ranging from 2.9 to 3.1) So it looks like the K3 doesn't recognize the two syn. Fw rew is 5.14 Any hint? I have not opened it yet. I have the old PLL if needed thanks IU3AZC Enrico __ 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
Re: [Elecraft] KSYN3A dead?
Hi Petr, I have two ksyn installed, and both worked fine for some months. I did not open my K3 in the last weeks, and two days ago my K3 was ok, so this happened without touching anything. An italian OM had another problem with a deprogrammed SYN. I wonder if Elecraft is aware of this and who's gonna pay the cost to reprogram it? thanks for the reply 73 de Enrico IU3AZC Il 04/08/2015 16:55, ok1rp ha scritto: Hi Enrico, The correct status for KSYN3A boards in TECH MD: ON is OK! So you should see SYN1 OK and SYN2 OK if you have both installed. The latest KSYN3A boards should work with 5.14 or later. Please open K3 and at first check if your cables are connected to right boards (not swapped by accident) and if all connectors are properly plugged in and have proper contacts please. It is common issue the TMP connectors has bad contact on the synths boards. Hope it helps, 73 - Petr, OK1RP - http://ok1rp.blogspot.com -- View this message in context: http://elecraft.365791.n2.nabble.com/KSYN3A-dead-tp7605860p7605868.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 iu3...@gmail.com __ 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] low IF out on K3
hello everyone, I just compared my k3 with a friend's one and my IF out is much lower than his k3. I suspected it when listening on a softrock, but now I can see a difference like 10 or 20db off. So I inspected my k3 and the IF out connector is fine. Multimeter says 0 ohms between bnc contacts and P86 pins on motherboard. What can I check next? Anyone did fix this same issue? thanks Enrico IU4AZC __ 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

I believe they made a change to increase the output on the "newer" units.

Re: [Elecraft] low IF out on K3
Hi, I confirm: R8 is labeled "133", so it is a 13k resistor. Enrico Il 07/04/2016 22:10, Art Hejduk ha scritto: Enrico, Yours should definitely have this change done then.

Re: [Elecraft] low IF out on K3
hello everyone. My K3 is # 80XX so it should be fine. With my multimeter I checked R8 and it's reading 270ohms (mounted on the board). From the schematic I guess there should be no DC flowing and that I should read 13.3k, so I think R8 is broken or the problem is in Q10 fet, being resistive on the gate. anyone has experience in this, before I start desoldering components and measure them? thanks Enrico Il 07/04/2016 22:24, Ron D'Eau Claire ha scritto: Older K3 transceivers (built before September 2009) do have lower output than later units. Elecraft published a modification that involves replacing a single resistor to bring up the level. They have a kit that includes an SMD and a leaded resistor (you can use either, only one is installed). Order the KIO3BUFFKT. You can see what is involved by reviewing the instructions available for download here: http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf If you have a 13K ohm, 1/8 watt leaded resistor or if you'd rather work with an SMD, a 13K 0805 size resistor, you won't need the kit. 73, Ron AC7AC -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Enrico Lorenzoni IU3AZC Sent: Thursday, April 7, 2016 12:55 PM To: elecraft@mailman.qth.net Subject: [Elecraft] low IF out on K3 hello everyone, I just compared my k3 with a friend's one and my IF out is much lower than his k3.

[Elecraft] white noise in headphones with beta firmware
hello, today I just updated my k3 with the latest beta firmware, so I could record monitor from line out. But as soon as I applied the update, I started hearing a white noise in my headphones. It is indipendent from AF level. Could you please fix the firmware so I don't have to revert and loose the recording ability? thanks -- 73 de Enrico IU4AZC __ 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
