I wonder if we as a NG might put together a design
for an HF rig that could be built with ease by novices
and experienced constructors alike?

I suggest that none of the CB-style gadgets of today's
CB-style rigs are necessary and that a reproducible design
having only the facilities of, say, the KW2000, would provide the
basis of any station.

Keeping it simple will increase the chance of success.

I suggest the following....
DDS VFO
VFO display based upon graphic LCD to simulate
the use of a tuning knob-plus-dial.
Tuning knob plus flywheel using optical sensors,
giving the "Feel" associated with traditional rigs.

DSP for the audio and mixing stages, perhaps
with a low IF of ooo 50kHz to resolve the ringing
problems that arise in narrow baseband filters
for CW.

ooo 100mW output allowing the choice of PA
for CBers-Masquerading-As-Radio-Hams or
running barefoot QRP for _REAL_ Radio Hams.

Any of the established CB types in this NG are welcome to join
this discussion, I only ask that your contributions be
meaningful and not the inane sneering 'n; jeering for which
you are famous.

Bring back the G2DAF rx/tx I say.

IMHO... QRP, for the new-to-HF ham whose Morse (and/or voice
procedures) isn't all that solid yet... and who's probably using a
comprimise antenna... is really not a good idea.

Save it for when one's got some experience under the belt & is
interested in trying something new.

The homebrew design that would, IMHO, bring a lot of new folks to the HB
fold, would be...

A simple, inexpensive, easy to duplicate, linear amplifier. 2-5 watts
in, 50-100 watts out; good for all HF bands; run from 12V. (yes, there
are certain advantages to using 28V, but 12V power supplies are cheap
and ubiquitous. I know I misspelled that!)

It could be used with a wide variety of existing HB QRP transceivers, or
with a variety of commercial QRP gear.

Is this yet another Cber coming to the defence of the cowering coward
RVMJ?


How's the Morse training coming along? Lets hope it's going better than the
potty training!

(I managed to work one of your Foundation licensees on 21MHz PSK31 last
week, but it wasn't easy to copy her QRP (and ESP!) signal...)

The alternative would be pretty silly though, wouldn't it? That is, the
more tests you pass the less power you are allowed. Nobody would upgrade,
would they?

If you start out with a defeatist attitude, and pass that
defeatism onto your protégés, then, yes, you and they
will be defeated.
