Enough talk

Its time for a link coupled tuner.  A look into the junk box and a trip to home depot and I got what i need..

This will be remotely tuned by dc motors and relays in my shed

Melt this one slab

Nice! Your signal has improved noticably since you put up for new antenna.

That is a funny looking guitar tuner though. ;D

I'm sure the bread slicer is a bigun, but I always get into the vacuum variable for the high voltage high curretn moments of radio. I know DERB will say that vac variable are gay, but what the heck!

Fred

well in the imortal words of peewee herman   ha ha takes one to know one haha

 ::)  ;D

That has to be the BIGGEST air variable capacitor that I have ever seen...

I guess that's Mr. Cap to us....

Beautiful PRS!  Caps and coil look cool too!   ;D

I wonder how much juice it would take to belt one of those down?  :P

The components definitely rate high on the cool scale.  It is possible that Slab might be a little jealous.

How big is your transmitter?  ;)

Jealous?? NADA! ??? ???

He better just hope the spacing on his capz is enuff to prevent arcage ;D ;D

Rememba, the proof o the puddin is in the eatin!! 8) 8)

Hey Ed. Here is a roller inductor to match the caps.

Hey Joe Do you have two of those inductors? I need a couple to build another tuner.

well the spacing on the smaller cap is 1/4 inch  the other is 5/8 inch.. the big one came from a 10 kw transmitter. the other i dont know.  anyway you slice it. (pun intended)  If I have made it this long with a 3kw mutha effing junk tuna I should be ok fine with this one. 

thanks for the compliment on the guitar.  I have that one and a mccartney edition  along with about 8 bcrich us hand made custom shop models

Where do you find those monster parts???  Ok, yea I have Tuna Envy...

ebay baby

I guess fortunately or UN fortunately for HAM fests, eBay is a source, although you're going to pay a higher price. Where did the good deals go? And the treasures under the table?
Fred

Phred,
        I have yet to buy anything from Epay. You just gots to git up offa yo ass and walk a few hamfests. I have found all of my parts for everything that i have built at local hamfests. You just gots to go out and look. And besides the festers are also good for a little social activity as well. Epay is a good example of paying for convenience.

Hi Steve. You mean like this?

Nice! Yours has BIG knobs too. ;D

Hey Joe contact me if you ever find a matched pair of variable inductors.
