[Elecraft] Firmware update process stalled K3
I wanted to install the latest firmware beta release (4.47). The process started, on the K3 display MCU LD appeared, but after a while the message appeared, that the update failed. The K3 stayed in the MCU LD mode and the K3 utility showed that there is a communication problem with the COM port. Trying to reactivate the COM communication failed with all possible COM ports my ELTIMA virtual port cable creates. Turning the K3 on and off didn't change anything, the MCU LD mode stays on. Also reinitializing the ports by turning the computer off and on again didn't change a thing, I could not get the COM port communication started again. Does anybody have an idea how to get back to normal without starting the EE INIT procedure (loosing all parameters)? Thanks in advance for your help!!

Thanks Dick for your help! It did do the job, I had to disconnect mymicroham microKeyer II , then it worked. So reading the help files sometimes really helps!

Go through the procedure described in K3 Utility Help, Troubleshooting, MCU Boot Loader. 73 de Dick, K6KR -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Axel Kaiser Sent: Sunday, February 26, 2012 11:59 AM To: Elecraft Reflector Subject: [Elecraft] Firmware update process stalled K3 I wanted to install the latest firmware beta release (4.47).

Re: [Elecraft] K3 does not transmit (FSK) on lower bands?
Thank you Greg, Joe and Richard, you solved my problem. In fact, the DATA MD setting was different on the lower bands for some reason. Actually I didn't know that this setting is band dependent. I checked the manual again and didn't find any remark to this respect in the Data Modes chapter. Anyway thanks again, you've made my day!!! This reflector is a marvelous thing! 73 de Axel DL3ZH Date: Sat, 5 Mar 2011 23:43:19 -0500 From: ve3...@storm.ca To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 does not transmit (FSK) on lower bands? Axel, The K3 remembers the DATA submode separately for each band. Perhaps you have the FSK D submode selected on the higher bands, but one of the other submodes selected on the lower bands. 73, Rich VE3KI DL3ZH wrote: I am having problems with my K3 in transmitting RTTY on the lower bands (160m -30m).

[Elecraft] RTTY filter for K3
To all you filter aficionados, first of all thank you very much for all your detailed answers to my original question, which roofing filter ist best for RTTY operation of the K3. Lots of very detailed and informative answers were given and even a general discussion on this issue among several others was started. But to tell you the truth, I am still somewhat uncertain, which filter to order with my K3. One of my theory books about HF technology, modulation, bandwidth and so forth, tells me, that the necessary bandwidth for a 170 Hz shift RTTY signal should be around 320 Hz. Now some of you guys write, that you are using a 250 Hz filter for RTTY operation. A 250 Hz filter though has this 250 Hz (ok, a few Hz more in reality) bandwidth at - 6dB attenuation, which means that the actual bandwidth at about 0 db is even less. So my understanding for a 170 Hz shift RTTY operation is, to use a filter of at least 400 - 500 Hz (at -6dB) in order to get all the information through the filter. This I can confirm also with my current OMNI VI+ which does not allow me to copy RTTY signals with a 250 Hz filter . So please, where is the point which I am missing with the K3, that you can work weak RTTY signals with a 250 Hz roofing filter??

[Elecraft] RTTY Filter for K3
Hi K3-folks, What would be the best RTTY roofing filter for the K3? Is the 400Hz 8-pole filter too small and the 500Hz 5-pole filter the better choice?
