Hi Geoff
The Icom 7800 costs more than most commercial HF transceivers which are all
type approved for marine radio or land mobile service. Currently radios have
to be Type accepted by the FCC before being sold. I cant see how adding 2 more
test criteria onto checklist will add costs when
My take is that in the extreme cw is an AM signal modulated by a pure square
wave and as such prduces infinite odd order harmonics which will appear as
sidebands/clicks. Filtering reduces the extent of the sidebands and smooths
the square wave shape particularly rise and fall times but you will

The manual is being completed as we speak. It will certainly be made

How about a little patience. What difference does it make? The installation
manual won't help much until we have it in our hot little hands anyway, and you
can't use it 'till you have it.
The internet has turned us all into a bunch of impatient mean-spirited people
who love to complain and
Among other items, the manual requires pictures for installation of the
K144XV components in the K3. Its not just an operating manual. We go
through a step by step installation process as we document the K11XV,
and that requires all of the parts to be here before the manual is
completed.

Commercial amateur equipment does need to be certified.
In the UK the certification is to Interface Requirement 2028 and the EMC
directives etc apply with rigs CE marked to show compliance.
The Foundation licence permits commercially available kits to be used

In addition to power up memory, I'd really like Mode memory. I find my CW DSP
settings to be considerably different than my SSB DSP setting (and a real
