Hello Everyone,
There was a loop antenna in the home brew build items that used a MFJ
9232 loop tuner. The loop was made of 3/8 soft copper. Does anyone have
any idea what the diameter of the loop was.
I didn't measure it, but it was something like 4 feet in diameter or so.

Paul,

If you are going to bend the pipe into a circular shape, make certain
you buy soft drawn copper (it comes in a roll).
The hard drawn copper pipe will not bend.

Re: NS-40 crystal switch

Neil Goldstein
 

KC9ON makes an add-on crystal switcher for the pixies, 49ers, frogs, and rockmites that he sells here:


I would think it should work fine for the NS-40.  I think he's temporarily out of them, but I ordered a couple from him on eBay and they should be arriving soon.  Watch the site for when he gets them back in stock.

A couple nights ago I worked a ham using a 4.5 foot loop using the
material you mentioned. He had a decent signal on 80m. I could
inquire how he matched it.

Re: Loop antenna at Ozarkcon

Charles W. Powell
 

Depends on what frequency you want to use and how efficient you want your antenna to be.  Check out the site:


This will give you an idea of how loop element diameter, circumference, power input, and capacitors affect the function and efficiency, as well as the voltage that develops across the capacitor.  At QRP 5 watts  you still get in excess of 500 volts over the plates.  And remember that diameter of the loop is circumference divide by π (πd = circumference, so c/π = d).

Soft copper 1/8” tubing makes a great coupling loop but it’s not very efficient for the radiator until you get up to 50 MHz.

Send a private email to me and I will send info on the loop I recently built.

NS-40 crystal switch

Bill VanKirk
 

I have an NS-40 I built a couple years ago that I would like to put on the air. I would like to switch 6 different crystals rather than change crystals to change frequency. Has anyone done this and if so is there anything special I need to consider in order to switch the crystals?
