Title: Nice pics of BC-610 resto and other neat stuff

Right down to the bare bones.  He (N0DGN) speaks in the third person which threw me off for a bit.  What's that mic anyway - cool.

Right click on the mike image; then click view image. View the browser line; it says, "http://home.comcast.net/~rbethman/IMAGES/Shure737A.jpg"
i.e. it's a Shure 737A

That's a beautiful rig.  Love that 250TH.   the 737A, the "waffle mic."  Wonderful xtal mic.  I lucked out on one year before last when Jeff, W0XV was up here and had a table at the Belvedere Hamfest.  He had a bunch of mics and I lit on that one and it came home with me.

I have that mic.  Maybe mine is bad. It sounds very thin.  Shure looks cool!

That's not another one of those mics that needs a very high Z, is it.  D-104s don't start sound decent until you give them 5 - 10 meg ohms to talk to.

Yes. I see shure suggests a 1 to 5 meg resistor.  I cant seem to remember what I tried. This mic on.  That might be the reason Al.

This mic doesn't need anything!

I feed it into the BC-610 as a dynamic mic.

It also has been used with an HT-32, HT-37, DX-60 and I can't remember what all!

She is a wonderful gal!  This one makes #2 for me!

I let #1 go with the HT-37/SX-101A that went to a school!

Really nice article on the BC-610, Bob.  Good thing I was saying nice things about you, huh?  Never know who's going to be "lurking"   ;D

Al,

Go right ahead and lurk!  It really wouldn't matter to *me* if some bad or true things get said!

Just an old cantankerous retired Sr. NCO.  By definition - *we* are thick skinned, hard headed, and most likely certifiably insane!

I appreciate all the comments from ALL!

The BC-610 is being picked up by WB2FCN.  Too mush mass for the arthritis!

The T-213 has a new home! It is in the hands of K1YCM!  He is going to take her apart, most likely polish the insides, although he said he won't repaint the outside!  It gives it its own character.

That one went from Texas, to Dayton, and then to Kennesaw, GA. 

Then it was in the back of my Son's pickup and brought to Manassas, VA!

Son temporarily lost control of the mass as he tried to come down the steps into the Den/Shack!

I simply reacted and grabbed one of the four handles, taking all the weight and regaining control.

Dumb reactions!  I paid for that one!

I am tickled that a fine Old Timer has her.  He wanted an AM Tall Ship.  He now does.  Les is a grand Gentleman!

His helper enlisted, or perhaps "drafted" is a better term, two young neighbors with *muscle*!

We then came to a singular consensus - Mine!  It was time to holler "stop!".  Let's do this a different way!

I had them unstrap it from the 700lb capacity hand truck.  The two MUSCLE guys then simply lifted it and placed it right at the back of the VW Jetta station wagon.  They then simply muscled it it into the air and leaned it over, sliding it o a piece of carpet that I gave to Les.

Hot dog!  It went right in!  I had the right concept for a change!

How the Jetta handled it I have no idea.  I added extra miscellaneous items that were simply occupying space.

Les did not leave empty handed!

My sig line says it all!
