Re: [Elecraft] K4HD Executive Summary Request -- strong signal performance
Thank you for your explanation Wayne. You are correct; turning off the noise blanker eliminates wide-band key clicks from strong, wide signals. Trying to put numbers to your "Aggressive settings of the noise blanker," I set about to find the NB level at which the clicks became noticeable. To my surprise, for the first strong signal I heard, I found NB levels of zero and 25 produced clicks, but a level of 14 did not. For other strong signals I heard over the next few days, a NB level of 0 always produced clicks, while other levels had varying effects. In the end all I learned was that NB levels were mostly unpredictable in how they produced signal artifacts, except that they almost always did.

Re: [Elecraft] K4HD Executive Summary Request -- strong signal performance
While I have a K4HD module on order for my K4D (0406) I am also interested in Wayne's comment about strong signal performance. On the CW bands, particularly 17 meters where I often operate, many times I have observed strong CW signals whose keying causes key clicks to appear some KHz away from their frequency. For example, the other night a strong signal from W1AW code practice at 18.0975 could be copied by its key clicks at 18.079. I have heard this behavior on other bands -- e.g., 40 and 20 meters -- and have reported it to supp...@elecraft.com, along with videos. So far I haven't heard any explanation for these key clicks. It could be that I have a flawed K4D or am using some settings that cause it. (I wasn't using either pre-amp when I heard W1AW's clicks.)

Hi Gord, The ongoing worldwide supply chain debacle has impacted K4HD module development. We’ve already redesigned PC boards twice to work around chip shortages. We’ll keep everyone updated.

They have not ever been very effective against power line hash which tends to be non-impulsive and highly random. That has not been my experience. Most line noise IS impulsive, and some noise blankers can be quite effective, but only if there are no strong signals nearby. I'm hoping a direct sampling receiver could avoid that problem. One method that has been used in the (distant) past was a second receiver tuned to a nearby but clear frequency to control the noise blanker. It seems that a direct sampling receiver ought to be able to do something like that. 73, Scott K9MA -- Scott K9MA k...@sdellington.us __ 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
Re: [Elecraft] K4HD question
Noise blankers were designed for repetitive impulse noise, the largest former example of which was ignition noise from vehicles. They have not ever been very effective against power line hash which tends to be non-impulsive and highly random. These days, repetitive ignition noise is not a problem for many, don't know why, there are still spark plugs in there. Power line hash comes from a myriad of sources ... hardware anchoring insulators, transformers, fuses, and the like, as well as micro arcing across dust covered insulators. It's highly random, over even small time intervals, and just not the enemy noise blankers were designed to fight. If Wayne had graduated from Hogwarts, he might have some magic to make them work on power line hash. Lacking that, not sure. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 5/29/2019 6:43 PM, K9MA wrote: I've never found the K3 noise blanker to be very effective on power line noise, and I've tried all possible combinations of settings.

Re: [Elecraft] K4HD question
Thanks for the reply, As I require diversity , the K4D is necessary, as I also require an autotuner, I need that as well. The costs are adding up. I certainly don't want a new rig that has in any way, less capability than the fully loaded K3s I have now. If a K4HD with autotuner is functionally excess to my having a K4D with autotuner, that helps me budget. 73, Gary KA1J > Any of these things you mentioned might not bother you now BECAUSE > you are using a K3. > > The K4D adds a second A/D chain with dedicated front end filters for > whatever band the second receiver is tuned to.

Re: [Elecraft] K4HD question
Any of these things you mentioned might not bother you now BECAUSE you are using a K3. The K4D adds a second A/D chain with dedicated front end filters for whatever band the second receiver is tuned to. Plus diversity reception. I seem to recall some reference to a “wide-band” mode, which may come in to play if the two receivers in the K4 are tuned to widely disparate frequencies (e.g., one on 80M, one on 20M). This could exacerbate the A/D overload issue with wide-band direct sampled SDRs. Wouldn’t be an issue with the K4D. Although you might need a K4HD to get to the heat-proof front end you currently have with the K3.

[Elecraft] K4HD question
At this time there are no nearby hams to disrupt my K3s. There are no local AM broadcasters that come in as overload. I do have issues with a few 2nd harmonic stations from the BC band, one for example from S. America on 1.8400. I won't likely be using my K4 at a contest site and I am the only ham in the house. With that, is there anything the K4HD offers me Rx-wise, or otherwise, that the K4D does not?

[Elecraft] K4HD switchable?
"> Can the superhet option be switched in/out independently for each of the K4D receivers? In theory." Why is this theoretical? My interest in the question is for use with WSJT-X modes where I currently use a 4 kHz - 5 kHz RX bandwidth. My understanding of the superhet spec is that it would be limited to about 2.8 kHz bandwidth. What is the max bandwidth of the superhet module and, if limited to 2.8 kHz, can it be switch out of circuit?

Re: [Elecraft] K4HD
I did exactly the same thing, back in 2009. I was determined to come away from Dayton with something to replace the old IC-735 I had used for the last twenty years, that would be worthy of the six-band quad antenna I had just put up. I was put off by the Flex, both for lack of QSK CW and SSB VOX, and made my choice Elecraft. I've NEVER been sorry.
