The D-104 had an impedance of 50,000 ohms.  As for using it with a modern transceiver..... a slight problem.  Google search for a homebrew impedance converting circuit for the D-104 to the modern rig.  It should be in interesting project.

As for "why" you would want to do this.....it's very understandable.  They're a cool mic!

'Mr. Defense Attorney.  The court recognizes the term A1A.  However, although being correct, the term A1A is recognized by less than 1% of the amateur populace even thought at one time it was one of the questions on the General Class ham examination. 

Is there anything else?"   Grin

WOJ:  If you want the genuine ASA mil, it must have the tractor feed.  It was necessary to pull the 5 layer paper through.

Do you recall: "3dits, 4dits, 2dits, dah.  ASA, rah, rah, rah!" ?

QE:  OMG!  Have I heard a variation of THAT scenario a couple dozen times.  Invariably it's with a woman who answers the phone.  Understand, this isn't a diatribe  against women.  Perhaps it isn't their fault.

But, I call an auto dealership....ask for the shop manager.....get, "Is there anything I can help you with?"  I say, "Noooooo..... need to talk to the shop manager.

She says, "What is it you need?  I'm sure I can help you."  So I go to great length telling her what my problem is and when I finish she either gives me some kind of bullshit answer or many times says, "I'll connect you to the shop manager." 

This goes on with auto dealerships, electronics places....and the list goes on.  I have actually done this at some places up to 3 times before getting help with a problem.....each time going through the whole speech!  Drives me crazy!!

Right or wrong,

I self-spotted myself as W3R over the last two weeks during the
special event.
If I was wrong.....oops !

BETTER TO BEG FORGIVENESS THAN ASK PERMISSION !

(Sure DIDN'T BUMP UP my Q rate, that's for certain)
Special event stations are a special case. For special event stations, a self-spot every 30 minutes or so, in idle periods, is OK in my book.

Disclaimer: My book is not everybody's book.

With the sale on now for the Argo VI I am going to buy one next week for portable use.

Just for fun I downloaded and installed the Argonaut VI Master Library and started up setup539. In looking at setup539 I can see no way to manage the rigs memories there.

It seems hard to believe that in 2014 that memory management would not be included in the software and that each memory would have to be programmed by using the VFO and the memory button.

Oh look, you answered VA2PBJ's response before he asked it!  Maybe your wireless network uses a time-jumping CCD antenna with a phase velocity > c:)

...
What is the phase velocity of the signal from end to end in a lossless 1/4WL open-circuit stub?
...
What is the phase velocity of a pure standing wave?
...

Hmmm, not sure what you're after.

vop of signal is that of the transmission line - 65% to 90% ish depending upon the line.

vop of the "envelope" of a standing wave is, well, zero, by definition.  No?  I'm not sure that the phase velocity concept is really defined for a standing wave....

That's great that Mr. Stone is doing a good job, and it's nice that you have said so. The question is, how to reconcile the good reports with the bad ones. If there are very good people working there, as you have testified to, then for some reason their good customer performance attitudes are not being passed on to others in the company. Perhaps there is no budget for meetings or training or mentoring along these lines at MFJ, we can only speculate as to why. But there appears to be a stark contrast between the "good" and the "bad" at MFJ.

Yes, well stated.  I don't think there should be lots of latitude in consideration given to them, though.  They know what they're doing, and have been in business a long time.  If quality was their overriding goal (like DX Engineering), they would have figured it out by now.  MFJ knows their market niche, and runs their business model accordingly.  They appeal to a lower-end customer who's mostly cost-focused and can accept most screw-ups without killing their business, because people will keep coming back for their inexpensive stuff.

I guess the only thing that gets annoying are the offended customers who make it sound as though they wanted a Ferrari and can't understand why they ended up with a Yugo.

That makes no sense. Who is this "official" and I wonder which definition of undermine he is using, to hurt, to subvert, to weaken?

Partly will depend on the diameter of the mast and the expected wind load.

I use the 4' military mast sections for Field Day and other temporary antennas.  (Well, one
was "temporary" for 6 years...)  Even with a TA-33jr up at 36', I've never had to guy it
other than at the top.  (I use baling twine and just tie it to the top section of the mast.)
That has survived some pretty strong winds on a mountain that blew tents around.

The aluminum mast sections are just under 2" in diameter and appear strong enough for any
reasonable antenna that we might want to put up when installed that way.

I also have the fiberglass sections, and they require more guying because the joints are
not as strong:  the wind blowing sideways on just the mast has broken the center joint
if I don't have enough guys.  Generally I'd suggest going no more than 5 sections up before
adding guys, and possibly every 3 sections above that.  (Using an odd number of sections between
guy points avoids having a joint in the center where the forces are focused on it.)
