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. --Neil W2NDG

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. 73, Don W3FPR

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:
toggle quoted messageShow quoted text
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. 72, Chas NK8O

Loop antenna at Ozarkcon
Paul Smith
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 ordered a loop tuner and it arrived today. I have some soft drawn coper but was not sharp enough to measure the loop. I have the manual but it calls for MUCH larger loop size than this was. Any help would be appreciated. de Paul N0NBD

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? W0PT73
