None of those 6m birdies here in Texas

I also have a pretty strong (-120dbm) and annoying 6 meter birdie. It is
when I am in cw mode and moves when I tune, intersecting with the passband at 50096 or so . It moves with VFO tuning, but at a much higher rate (viewing on the P3). When I have tuned 1 khz higher, it has moved almost seven khz higher. It also seems to drift a bit...unlike the stationary (internal) birdies that are rather weak and stable. I have cleaned up my cabling and tried to make sure all the boards and case bits were bonded properly, but those efforts have had no effect. I have noticed a similar birdie on 20 meters (ssb) around 14186 or so, but it moves opposite the direction of tuning. My efforts seem to have had no effect on them (including Sig Rmv). I have been told I will just have to live with them, and I can, but it is frustrating nonetheless.

I have a birdie at 50.09465 cw normal not rev on a cold k3 and the one at 14.186. The latter being weaker and neither adding to the s meter. My shack has no computers but a wal wart or two so I can confirm those two.
Auto notch has no effect. I believe as Tom mentioned there is a method to remove them or that specific frequency they are on ( not sure which) but I havnt been bothered enough by them yet. 73 Mike R Sent from my spy ring On Jul 6, 2011, at 12:44 PM, Robert Redmon <[hidden email]> wrote: > I also have a pretty strong (-120dbm) and annoying 6 meter birdie.

I got one at 28.13471Mhz and reduced it by moving the TMP cable between J84 and J85 of KRX3. Moving the TMP cables does have effect on the birdies.
Just try to resit and change the positions of the TMP cables, you will get some improvements.

It may just be my more or less casual observation, but ---
Many seem to becoming "loose" on what is defined as a "birdie". Proper use of the term is to refer to a "fast tuning" signal that is produced by the receiver's mixing scheme and the harmonics thereof. That is a true "birdie". Other annoying signals can be heard which originate from something other than the receiver itself. Those signals are real signals (whether desired or not) that are picked up by the antenna. For true receiver birdies, re-orienting the TMP cables and/or the use of the Signal Removal Tool in the K3 can be effective, but for signals that originate outside the K3, the only real cure is to suppress them at the source. Yes, I understand that identifying the true source can be a burdensome chore, but differentating between internal receiver "birdies" and external signal sources is a good starting point. Terminate the K3 antenna input with a well shielded dummy load (with a very short length of coax), and if the "birdie" is still present, it is a true receiver birdie, but if it is no longer present, it is a real signal and the source must be found to eliminate it with ferrites or other suppression devices. 73, Don W3FPR On 7/6/2011 6:04 PM, Mike Rodgers wrote: > I have a birdie at 50.09465 cw normal not rev on a cold k3 and the one at 14.186.

Hello Don,
I would even play a more safe game to distinguish whether it is a true birdie. How about using a 12v battery instead of a power supply unit during the test?

Johnny,
Yes, that is an excellent suggestion, especially if the K3 power supply is a switcher. 73, Don W3FPR On 7/6/2011 9:05 PM, Johnny Siu wrote: > Hello Don, > > I would even play a more safe game to distinguish whether it is a true birdie.

All,
Be sure that the antenna has been disconnected and a good dummy load is connected in its place to the antenna port via a very short piece of known-good coax. Better to have a 50 ohm termination connected directly to the antenna port. 73 Gene K1NR K2 6K On Wed, 06 Jul 2011 21:14:02 -0400 Don Wilhelm <[hidden email]> wrote: > Johnny, > > Yes, that is an excellent suggestion, especially if the > K3 power supply > is a switcher. > > 73, > Don W3FPR > > On 7/6/2011 9:05 PM, Johnny Siu wrote: > > Hello Don, > > > > I would even play a more safe game to distinguish > whether it is a true birdie.

MCU Load Failure w/FW 4.36 or 4.39
|

In reply to this post by Johnny Siu
I've been running FW 4.25 for some time now, primarily because there wasn't any compelling reason for me to upgrade. However, this evening when I saw Wayne's announcement for 4.39 I thought I'd give it a try. Unfortunately, I ran into an unusual problem.
I've installed FW dozens of times over the past three years that I've had the K3, and never once saw a FW failure until this evening. The K3 Utility begins loading 4.39 MCU, and when it gets to the point at which the utility invokes an MCU reset, nothing happens and the K3 Utility loses communication with the K3. Manually placing the K3 into the MCU load mode and restarting the K3 Utility was required to re-enable communications. I ran the loader again, and it failed the same way. Next, I tried to load 4.25, and the entire process ran through to completion without a problem. But if I try to load any FW above 4.25, the process always fails the MCU load at the MCU reset stage. My K3 is an early serial number (early 200's), has the KXV3, KRX3, KPA3, KAT3 options, and I have the P3 (but no KPA500). I'm running the K3 Utility 1.4.4.25 on Windows 7 with a "real" serial port. Any ideas what might be wrong?

Just to double check, are you clicking "Send All New Firmware to K3" and not just loading the MCU?

Dick, Was it an err key warning? IF so, I had the same thing. I looked it
up in the Manual, of all places (go figure) and it was advising that the radio had a transmit function on when the rig turned on. Once I checked one of my three keys and turned the rig back on issue resolved. 73, Bill K9YEQ -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Rick Prather Sent: Thursday, July 07, 2011 10:35 AM To: Scott Prather Cc: [hidden email] Subject: Re: [Elecraft] MCU Load Failure w/FW 4.36 or 4.39 Just to double check, are you clicking "Send All New Firmware to K3" and not just loading the MCU?
