This is a neat little rig, but I agree with the fellow who said he thought a 10
meter version would be great. Before the first iteration of the Ten Ten club,
when it seemed like all my DX QSO's on 10 were with the British and Australians
and they seemed to always be running a rhombic antenna,
Based on my sample size of 43 that results indicate that 99 percent
responded affirmatively to each of the statements in the first survey. I
concluded that there is a high likelihood that the entire populations of
like hams would express a similar response rate at a 95 percent confidence
Sure I know how to solder. I learned building my own first 6V6 transmitter.
Then when I was new with Western Electric, I could solder over 1000 connections
a day without error, we all could. Later we used Wire-wrap guns, and I could
get 1200+ fanned, skinned and wrapped per day, all without
HI Dave: not to throw water on you premise, but the sample size is far too
small and the group sampled is not representative of the population. My
guess is that the true range is less than 50% for all licensed hams,
probably much less! I would wager 50% are not even active. Bernie W8RPW

Think about how much interference we would have on all bands if more
than 75% of the licensed hams were active. That last number I saw was
over 700,000. Man, what a din that would create.

David's message stated like hams which infers hams on the reflector, not

David,
I have to disagree with your conclusion. Your survey was taken within a unique
subset of the general population of licensed hams. The mere fact that a ham is
a member of this email group almost makes it a given that they were born with a
soldering iron in one hand and a roll of Ersin

I agree. I also have decided it was a mistake to eliminate the CW
requirement for the license, not because it is necessary for
communication (it is not) but because it is necessary to communicate
with the most basic simple homebrew rig, a CW transmitter.
Now, even if we teach homebrewing in the

There is a slight backlash going on against them dropping the
CW requirement.
I have heard about a number of people who have rebelled against
the ARRL and FCC's boneheaded anti-CW decisions, and actually
consider CW as some kind of a forbidden fruit that they want to try.
Just anecdotal
I have a Retro 75 and it is great. I also don't represent Dave Benson the
designer. That said I think Dave decided to design a simple fun radio to
build which is very usable at a very attractive price. As I see it, putting
a rig like this on 10 meters will require more parts, more stability,

The wilderness radio sierra does 160 to 10, has a better receiver, 5 watts

Actually no, it costs $369.00 for the version that only covers 80m
through 15m and you have to presumably pay more than that if
you want to use 160m, 12m and 10m.
You have to open it up and fiddle with modules to change bands too.
Oh, and it seems like the digital display is an optional Extra.
