I have been informed that you can get all of the Tuner memory
information using the KAT-500 app. You must go to the KAT-500 Command
Reference Manual for instructions, and it makes it very easy to get what
is needed for debugging purposes.

There's a new production release of KH1 firmware (rev 1.27). Please see
release notes below.
Additional information on using FT8 for self-ID during field outings will
be posted to the KH/KX/AX forum. This info will also be in the pending
update to the KH1 owner's manual.

KH1 MCU 1.27, 23 November, 2025
* FT8 TRANSMIT USING 1-HZ VFO OFFSET COMMAND: An ?FO? (1-Hz frequency
offset) host command has been added to support SOTAmat FT8 self-spotting
for SOTA outings. An external hardware interface (e.g. SOTACAT) and smart
phone or laptop can now be used with the KH1 to transmit FT8 packets or
potentially implement full FT8 transcieve. Refer to the KH1 Programmer?s
Reference or Owner?s Manual for full details.
* MORSE AUDIO FEEDBACK: By setting MENU:SW TONES to one of several CW code
speeds, Morse audio feedback will be emitted on every switch tap/hold, plus
coarse VFO/band changes in BAND/MODE, as well as selected menu entries. On
entry to BAND/MODE, the KH1 sends kHz and 100s of Hz digits, providing
Morse frequency readout. If a power-on banner (such as ?N6KR?) has been set
up using KH1 Utility, it will be sent in audio Morse on power-up. For full
details refer to the KH1 Owner?s Manual.
* QSK DELAY MENU ENTRY: QSK delay can be set from 0-2.50 s. The default is
0.00 (full QSK).
* 100 kHZ/1 MHz STEP SIZES IN BAND/MODE ON SWL BAND ONLY: While BAND/MODE
selection is in effect, hold the VFO knob (> 0.5 seconds) to toggle between
100 kHz and 1 MHz. Provides much faster QSY on the SWL band.
* MONITOR LEVEL SAVED ON EXIT FROM MON SETTING: Previously, the setting
would be lost on power-down.
* MANUAL ATU SETTINGS SAVED: Previously, in MENU:ATU PARAM, manually
adjusted LCN values were not saved.
