[Elecraft] KPA 1500 on 12 meters
Makes the impedance here in parts of Florida a moving target. Its not how high the antenna is above the ground (sand) it's how high above the water table which can vary from a few inches below the surface in July to 25 feet or more below in Dec-Mar in our dry season.

It's faster as well as brighter -- the K4 screen was easily readable in diffuse daylight during Field Day, while some other rigs' displays were not. The K4's panadapter area using the standard display format is 25% greater than the P3's. This doesn't include the per-VFO "mini-pan" displays that overlay the S-meters, when desired, for fine tuning of signals. Thanks to the much larger LCD, variations on the panadapter could be created that are much larger than this, at the expense of some per-receiver icons and the S-meters. So far we haven't felt the need, partly because the K4 includes an HDMI output that can drive an external monitor of any required size. This external monitor can be configured to display just the panadapter, with independent settings from the panadapter on the LCD. Beyond this the K4 display provides: - dual-pan mode (separate panadapters for main/A and sub/B) - single or dual text decode windows - far more digital signal processing horsepower (in aggregate, roughly an order of magnitude greater than the K3S+P3) - built-in IQ data streaming for use with computer applications - a configurable multi-band mode to allow a quick check of activity on your favorite bands - more flexibility in terms of display functions - overlays for various functions (e.g.: DX call station list, help information on all controls, RX/TX graphic EQ, alphanumeric keyboard for message/macro/menu entry, etc.); - virtually unlimited code space for future expansion; examples might include high-performance data decoders, AZ/EL display, custom station controls, image display, etc. In short, the K4's display is much larger and more versatile, providing the kind of control visibility and convenience that's only possible by integrating the display into the transceiver itself.

Re: [Elecraft] I note that the mechanical strengthener for the K3 synthesizers is no longer available
We still have them, K3STFNR It comes up on the website. It is for mechanical vibration pickup dampening, mainly needed on the Main as that is used in TX.

[Elecraft] K4 panadapter vs. P3
> David Stout wrote: > > I would like to see a comparison of the P3 and K4 in full screen mode. Is the > K4 scope faster, higher res? Hi David, The K4's LCD has nearly 3x the area of the P3's, and 5x as many pixels. The resolution (pixels per inch) is about 30% greater. It's faster as well as brighter -- the K4 screen was easily readable in diffuse daylight during Field Day, while some other rigs' displays were not. The K4's panadapter area using the standard display format is 25% greater than the P3's. This doesn't include the per-VFO "mini-pan" displays that overlay the S-meters, when desired, for fine tuning of signals. Thanks to the much larger LCD, variations on the panadapter could be created that are much larger than this, at the expense of some per-receiver icons and the S-meters. So far we haven't felt the need, partly because the K4 includes an HDMI output that can drive an external monitor of any required size. This external monitor can be configured to display just the panadapter, with independent settings from the panadapter on the LCD. Beyond this the K4 display provides: - dual-pan mode (separate panadapters for main/A and sub/B) - single or dual text decode windows - far more digital signal processing horsepower (in aggregate, roughly an order of magnitude greater than the K3S+P3) - built-in IQ data streaming for use with computer applications - a configurable multi-band mode to allow a quick check of activity on your favorite bands - more flexibility in terms of display functions - overlays for various functions (e.g.: DX call station list, help information on all controls, RX/TX graphic EQ, alphanumeric keyboard for message/macro/menu entry, etc.); - virtually unlimited code space for future expansion; examples might include high-performance data decoders, AZ/EL display, custom station controls, image display, etc. In short, the K4's display is much larger and more versatile, providing the kind of control visibility and convenience that's only possible by integrating the display into the transceiver itself.

Re: [Elecraft] K4 Delivery
Any update on delivery dates Thank you Ken WB8PKK Sent from Yahoo Mail on Android On Thu, Oct 17, 2019 at 11:32 PM, Eric Swartz WA6HHQ - Elecraft wrote: Hi Tom, I apologize for any confusion on K4 status. We really appreciate the support you and others have given us with your K4 orders. We’ve been very busy keeping our heads down and working hard finishing key K4 features and getting everything lined up for production, including getting critical long lead parts on order with committed delivery dates. We are being very careful about getting this right and not cutting corners. I’ll make sure to post updates more often here and via direct emAil to K4 order holders as we converge to keep everyone informed and up to date. We’ll also make more posts describing some exciting features we are adding to the K4 design. We’ll be off line through this weekend at the ARRL Pacificon hamfest. I’ll make sure to post here links to any video interviews we give there on the K4 and its newest features. 73, Eric elecraft.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 Message delivered to backhoe...@yahoo.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 Message delivered to arch...@mail-archive.com
