[Elecraft] No Information On Display - Blank Display
Hello, I have a problem. When I turn my K3 on I get a bright orange completely blank screen. No nothing. Then when I go to power it off it will not respond and I have to use the power supply to cut it off. Any ideas?

Re: [Elecraft] [K3] K3 Distorted Sound while using AM
Thanks to all that have replied in trying to help me! There was just a new download posted from Elecraft K3# for (3.66). This seems to have taken care of all the problem I was having. The radio is now sounding much like a Superb SW receiver in its sound. I will be testing it on AM as well as the New AM mode, synchronous detection! For anyone who has not tried it, it is the cats meow. Listening to Foreign Broadcasters is something to behold, if you have not had the pleasure please cheek it out! It is especially interesting when (the signals have) multiple hops or maybe going over the polls to your receive antenna! I am very much aware that there are many SW (Short Wave) Listeners (and a few of us hams) using the Elecraft K3, please enjoy! Thanks again for all who have answered my original question Regards, Rick Richard Jones - KJ5QY wrote: Hello, I am having a problem when I go into AM, or AM sync.

After more investigation I found that if I rotated the shift (While in AM or Sync AM) control from its standard (Normal) value of 1.50 to 1.55 this horrible distortion would disappear?

Re: [Elecraft] [K3] K3 Distorted Sound while using AM
Hey Bob, Sorry for not getting back to the board been a busy day. I have checked all the wiring. I have tried the 6hz AM filter. This really has me stumped. I will give Elecraft a call the first part of the week and see what we can come with. Thanks, Rick Bob Naumann wrote: Have you checked the wiring to your external speaker?

No, I do not have the AGC Off, nor have I changed any of the settings within the AGC (Menus). I should have stated that in my original post. Anyway, I am really stumped as what the problem is. If you happen to have a K3 equipped as mine, could try to listen to an AM station with the Volume turned up, to see if you are receiving the distortion? I should have been more specific, the radio is totally loaded. It does have the 8 Pole filters in both receivers. From my recollection I have the following filters: 250 Data CW, 2.1 for SSB, 2.8 for SSB, and 6 for AM, and 13 for FM. I hope this makes it a litter clearer and not more confusing.

The distortion and eventual cutting out of audio at high levels you are describing sounds a lot like the intended AF limiter action. If so, the solution is to either turn on AGC, or increase the AF LIM setting closer to 30. I find an AF LIM setting of 28 allows as much dynamic range as I want while still protecting my tender ears from various pops and static crashes. The AF limiter is intended to protect your ears and speakers from unexpectedly loud signals when AGC is turned off. It will prevent the output from exceeding the preset value at the expense of distortion. 73 -- Joe KB8AP On Dec 5, 2009, at 8:50 PM, Richard Jones - KJ5QY wrote: Hello, I am having a problem when I go into AM, or AM sync.

Re: [Elecraft] [K3] K3 Distorted Sound while using AM
I think I found at least one of the problems. If you go into the RX EQ (by clicking the MENU button, then turning the knob until you see the RX EQ 1). Next, turn the lowest base control (Number 1) up from the 0 EQ position until you here the distortion on AM. It will not take much. On my rig, just taking it a few levels (Db) above the reference the distortion on AM is there in a vengeance. The following is the most important as I have found: If you have/get the distortion and you raise the Shift Control (While in AM or AM Sync) from *150 to 155, the distortion completely goes away!!! I am not sure what is going on here. I hope this, and the posts above will give some additional information on what I am experiencing, and hopefully an answer.

Re: [Elecraft] [K3] K3 and Firewire
Hey Paul, This is a great topic. Sony, Apple, and a few other companies have been using the Standard IEEE 1394 Interface, commonly known as FireWire for a number of years. It does have many benefits. From my limited knowledge as I am not an EE, the protocol seems to be an extremely efficient way of connecting our endless devices. I do use this protocol a lot. Rick Paul-285 wrote: Just thinking out loud into the future Firewire can do a lot of things that USB and serial communications never will. It's faster with video and disk I/O because the protocol is leaner, and you can create networks with it. I think that a FireWire network between a rig like the K3 and a computer would be the perfect interface because every piece of software can have its own dedicated connection to the radio, something difficult to implement with a serial connection. Firewire will also stay around because it's used as the Fly-by-wire bus for the F-22 Raptor. Any thoughts?

Re: [Elecraft] K3 Beta Firmware Rev. 3.57: Synchronous AM Detection (AM-S); misc. improvements
I have been using the Sync tonight on several AM SW stations. I have had very good results so far. Depending on the QRM the USB LSB do make a great difference. I have been waiting for this feature! Thanks, Rick -- KJ5QY wayne burdick wrote: K3 beta-test firmware revision 3.57 (with DSP rev. 2.45) is now available. This revision includes Synchronous AM detection, which has a clear advantage over the regular AM detector during selective fading. In this mode, the K3 can optionally track AM stations that may be slightly mistuned, as you might find in an AM round-table on 75 m. It's also convenient for automatically zeroing in on AM broadcast stations. There are other considerations when using Synch AM, so you should read the release notes (below) before trying it. We'll be further refining our AM-S implementation in a later release, based on your feedback. Please send any questions to k3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 3.57 / DSP 2.45, 11-7-2009 Misc. Improvements: * TUNE SWITCH: “Double beep” with NR on eliminated. * DATA A: Loss of power when using TUNE corrected. New Feature: Synchronous AM Receive * SYNCHRONOUS AM: Outperforms regular AM during selective fading. Provides optional automatic VFO tracking of AM signals up to +/- 2.5 kHz. Select AM mode, then hold ALT to select AM-S. The -S icon flashes slowly if the signal is noisy. Select AM-S LSB or USB using SHIFT; one of the two sidebands may reduce QRM. Sync AM also works with diversity receive. (Note: Some AM broadcast stations encode their carrier, resulting in a low-pitched noise when Sync AM is turned on.) With Sync AM you can tune manually, or use automatic VFO tracking: -- If tuning manually, you need to tune to within +/- 10 Hz of the actual carrier frequency, at which point the K3 will phase-lock to the carrier. -- To enable VFO tracking, tap CWT, which turns on the T icon. Or, tap SPOT to engage VFO tracking just long enough to lock. When tracking is on, the VFO may “hunt” slowly across a span of several Hz. IMPORTANT: For AM QSOs, use SPLIT mode when VFO tracking is turned on. VFO B (TX) will remain fixed while VFO A tracks RX signals. Limitations: At present, VFO B cannot auto-tune in AM-S. Also, both VFOs will always be in the same mode (AM-S LSB or USB). Remote Control Command Changes: * UP0/DN0/UP$0/DN$0 moves VFOs 1 Hz. Similarly, UP8 and UP9 move the VFOs by 100 and 200 Hz, respectively. __ 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 -- View this message in context: http://n2.nabble.com/K3-Beta-Firmware-Rev-3-57-Synchronous-AM-Detection-AM-S-misc-improvements-tp3983997p3984659.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
