Re: [Elecraft] First Contact with KX3 But strange behavior observed
Hi Doug, I assume you don't have the KXFL3 roofing filter installed. I had the same issue. Make sure that in the MENU --> temporally turn on TECH MD [ON] , then select Rx xFIL and then set it to [not inSt]. I think you will find the setting in [norm]. This should fix that issue. 73, Chris w0anm Doug Person wrote: >The KX3 arrived many weeks ago and just haven't had the time to get it >assembled and on the air.

Re: [Elecraft] K3 Check Your Buttons
Hi Paul, I have K3 #509. I tested my keyboard and I also found some flickering on some buttons. I never had any issues with operation. It might be interest to compare which buttons are flickering. During the Scn Adc test, the following key's second value would flicker: Button 1st value2nd val 5 3 1xx 6 5 1xx M27 1xx Cheers, Chris - w0anm Paul Ferguson wrote: > I own K3 #757 and recently noticed some of the front panel buttons were not > working.

[Elecraft] Re: K3 Firmware Rev. 2.76: No AF noise burst; PRE/ATTN independent for sub RX; etc.
Hi Wayne, No problem, I understand now what's occurring. Merry Xmas to all, Chris wayne burdick wrote: Christopher Kovacs wrote: I too still suffer from the notorious "pop" when powering on. I would be interested if this change may help. The "AF noise burst" that is eliminated by the latest firmware was caused by the AGC being turned off until about 2 seconds after power-up. If you had been tuned to a strong station, with the old firmware, you could hear a couple of seconds of very loud audio. That no longer happens. The "pop" heard in the speaker when turning on is an inherent property of the speaker amplifier IC, and cannot be changed in firmware. If we come up with a way to minimize this, we'll let you know. Meanwhile, you could plug in your headphones just when turning on power; this cuts off the speaker amp. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I too still suffer from the notorious "pop" when powering on. I would be interested if this change may help. 73, es happy holidays Chris Stewart Baker wrote: On my K3 there is still quite a loud speaker 'pop' with Power On and Off after loading firmware revision 2.76. Looking at the NS data sheet for the audio amplifier IC shows that it has click suppression built in. The length of the suppression period is determined by the value of the capacitor on the Bypass connection.The value of the bypass capacitor is related to the input coupling capacitor. On the K3 cct diagram this is shown as a 0.47uF, which suggests a 10uF be fitted to the Bypass connection to give a click mute period of 0.4S. However, the K3 cct diagram shows a 3.3uF fitted, which gives only 0.12S. Any benefit increasing the value to 10uF ? 73 Stewart G3RXQ On Tue, 23 Dec 2008 10:37:46 -0800, wayne burdick wrote: K3 beta-test firmware revision 2.76 (with DSP rev 1.98) is now available. See release notes below. Please send any problem reports to k3supp...@elecraft.com.

The '2' key on the numeric keypad now provides tone feedback when used for numeric entry or within menu entries. There's no tone when it's used as "REV" (temporary A/B VFO reverse). * SSB TX AFTER VFO A/B SWAP: Transmit filter settings are now correct after any A/B swap, regardless of the modes of VFO A and B. This had been noted by some customers as a problem on power-up, but it could occur anytime the VFOs were in different modes at the time of an A/B swap. * INDEPENDENT PREAMP AND ATTN FOR SUB RECEIVER: The preamp and attenuator settings for the receiver are now independent of main. On each band, you can set up the sub's preamp/attenuator as desired using BSET. The sub's preamp/attenuator are separate even in diversity mode, where you'll often be using a lower-gain antenna for the sub receiver. Note: A second tap of A>B within the 2-second window still copies all main receiver settings to the sub, including preamp and attenuator. For software developers: * "FR0" COMMAND (SPLIT CANCEL): Now correctly restores the VFO A arrow icon. * CONFIG:KPA3 MENU ENTRY: The parameter for this menu entry is now accessible via the "MP" command. * "FA"/"FB" commands and loss of PLL lock: Large FA/FB frequency steps were, on rare occasion, causing loss of PLL lock. This has been corrected. * Added "PA$" (sub RX preamp) and "RA$" (sub RX attenuator) commands. This is in conjunction with the sub preamp and attenuator settings now being independent of main (see above). During BSET, both return "?;" at present. --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
