Another approach is used for the WA5VJB "Cheap Yagis", where a "half-folded" driven element...
Thanks for the links!

This country's media supports one political party.  There isn't a whole lot of difference between our current news media and
the media in the USSR or modern day Russia.

Undeniably true. That and other issues summed up quite well here:

I use a computer headset with my IC-7100, and it works just fine.  I needed to wire up a cable/adapter to fit the modular plug on my rig, but that was pretty simple.

The only issue I can see is how you're going to get power to your headset.  Most computer headsets use a condenser mic element, and the TS-140 is wired for a dynamic element.  That means that the 140 doesn't send any voltage over the mic line, and the condenser element in the headset needs at least 3 volts to operate.  You'll need to build a little power/interface box to supply power to the mic.  You'll find lots of info - just do a Google search like K6LO suggested.

Good Lord, in that case, I'll take two!


OTOH, it seems that when the XYL hears the radio, she knows where I am and how to find me.

Maybe a headset would keep the QRM down better..... Not sure if I want to advertise with that sign!

Chris I won't get into how Kennedy won the election but I will say that IMO his directive to land a man on the moon was probably the most important directive a modern day president has ever given.

And Kubrick did a great job making the film... Although I found the moon buggy to be over the top, and excessive.

They land that tiny capsule, yet they brought along a moon buggy? Yeah right..

I run a Hy-gain TH11DX up at 54 ft  and we run a Cushcraft XM-240  2 element  up another 11 ft higher   I did not see any change to the TH11DX  when the 40 meter beam  was put above it .
Bandwidth seems to be up to specs on both antennas.  I run both antennas on the tower the same directions as we have John  W8RAT antenna lift on our Rohn 45g tower to lower it all down to ground level

Just because one does not see a change in VSWR, does not mean that gain and F/B has not been affected.

Great idea! But drop the idea of having the ability to "buy a QSO".

Even if it doubled the number of DXpeditions?

Remember, this idea would apply to a relatively few people.  No one has to do this. 

The problem with the DXing game, as we know it, is that while we may piously resist the idea of a sked, the result is, at present, we rely on the DXpediitoners themselves to fund the bulk of the expedition costs.

I'm not so sure that's really more virtuous in the end.  It is our custom, but I find it strange.  Why should the DXpeditioner pay quite so much more than I do to make my DX QSOs possible?  They do so at present and we have the number of DXpeditions we do as a result.

If we want more activity, we (or some of us anyway) need to find ways to make people willing to contribute more.  Your suggestion is the status quo.  We know how that comes out.  The DXpeditioner subsidizes us.

To me it really boils down to why do I play DX-ing?

What if $500 would give you a sked with P5? I am pretty sure I would NOT do this, not even if it was my 339!
It's like a hunter who did not score anything, goes to the pet shop and then stuff the animal and hang it on the wall.

Donating (or kickstart for that matter) money to an upcoming expediton, fine, excellent. Great idea! But drop the idea of having the ability to "buy a QSO".

Tom, Re: the 47 volt secondary xfmr.
Depending upon the Volt Amp rating, you may be able to hook that one up "backwards"

(The Insulation Resistance is a factor also, but I doubt you will have an issue going from 47vac to 115.)

Assuming it is a 115vac primary 115/47=2.45

Wired in reverse yields 115 x 2.45 =~281Vac
Very unlikely that you could connect a 47V secondary as the primary to 115V. Core saturation is the most likely outcome, causing serious copper overheating.
