Wayne,
I have to agree with you on that, I am amazed at the K4Ds performance...
I have several local hams, all within a half mile of me, and they
never really bother me... All but one has a K line of some sort, so
they are all clean signals... The only one that tears things up is
running a rig other than a K line rig... So... THANK YOU for your work
in making the D a great rig!!
73, and thanks,

Hi Dave,
The HDR module will provide higher blocking dynamic range, though in practice this extra
headroom would rarely be needed (typically in "my neighbor's beam is aimed right at
me" situations).
The K4D's ADCs are state-of-the-art 16 bit units with dither. We carefully
manage front-end gain ahead of them. Also, if there are many signals on a band,
such as in a contest, absolute peak voltage seen by the ADCs tends to be spread
out. All of these factors lead to the performance you've observed.
Many of those who originally ordered a K4HD have gone with the K4D with
excellent results. In fact, the performance is even better than we'd predicted
during the early design phase.

Wayne,
A question for you on the HD module... What will that bring to the party, the
K4D does not support now? I have been amazed at how well the K4D does with
strong signals, and I can't really see how you could make it a lot better...
Is there more I am missing?

Hi Pete,
The K4/0 team is independent of the KH1 team. Both are happening in parallel.
We still have supply chain issues with parts for the K4 HDR module, though
progress is still being made on that front.

But when will the K4HD and the K40 be released? I would think the market for
either of those would warrant some priority

We're pleased to announce the new Elecraft KH1 -- a fully integrated, hand-held station for those who combine outdoor adventure with amateur radio. The KH1 was designed from the ground up with instant deployment in mind. It includes: - an entirely new form-factor optimized for HT-style CW operation (as well as table-top), with both knobs and key at the bottom - a built-in whip antenna matching network and clip-on whip that gets you on the air in seconds - internal ATU that works with both the whip and BNC-connected antennas, including random-length wires - a complete logging solution, with folding logbook tray, clip-on pen, easy-to-manage paper log sheet stack, real-time clock, and 32 kb of EEPROM for electronic logging of all transmitted text - plug-in keyer paddle that flips over for safe storage - scanning/mini-pan feature for hands-free signal search on quiet bands - 2.6 Ah Li-ion battery pack and zero-RFI internal battery charger that works with any 12-14

includi
ng small solar panels With all of the the above (the Edgewood Package) the KH1 weighs in
at only about 13 oz. It's so light you can operate indefinitely, whether sitting,
standing, or walking (pedestrian mobile, or "/PM"). It's the perfect size, with
total volume about half that of our all-band/all-mode KX2 transceiver. The KH1 covers
40-15 meters, with over 5 watts output on all bands at from the internal 11 V battery
pack. Its ergonomics are ideal for CW operation. It will also do CW/SSB cross-mode, and
can copy AM and SSB on SWL bands from 6.7 to 22 MHz. The rig can also be 100% remote
controlled via the supplied USB cable. Our newest radio has been optimized over the past
year with the help of experienced SOTA, POTA, and QRP field operators. Its small size and
high level of integration have already transformed their expeditions, allowing operation
from anywhere, anytime. (One operated /PM for many hours during 2023 Field Day, making
contacts exclusively with the att
