Gary, Thanks for posting those interesting results. The part I have reproduced below told me all I needed to know. Test Freq. 300 uH 400 uH 500 uH

Jim, I just had an epiphany about the balun transformer today! I tried it out and quick tests are amazing for CM rejection. Please give it a try. 1) Keep your secondary windings the same. 2) Wind

Hi Gary, Your figures are very interesting. And it seems that the S/N values only vary by one point between the 300 to 500uH range of coils and across all your measurements. Would not the 300uH coil

Hi Phil, Thanks very much for doing this, and sorry that I haven'tprovided help (having been tied up with other projects). I would bevery happy to assist you in drafting the "World of Ultralight"

WTIC is directional at night. Down here in South Carolina they just disappear at the time they go directional. Powell

Speaking of [copper] wire, what would you recommend? Solid or stranded? Any easy to work with gauge, or something in particular? - FARMERIK

Hi Roy, Thanks for your comments, and suggestions throughout the experimentation(which have all been appreciated). According to the test results, the choice of coil configuration amongthe four

Hi Jim, Just read your description on how you test that the loopstick is resonating and performing correctly into the high end of the band. I agree that this would work well and should be applied as

With 7 turns, that loop would be perfect for AM.- FARMERIK

I ran the numbers for a 40 X 40 inch square loop, with 1/3 inch spacing, and came up with 24 turns for 2208 uH. That should do. It looks like my 4 foot loop is around 3500 uH. - FARMERIK

Hello All, Scott is referring to comprehensive measurements performed here on fourdifferent 7.5" loopstick PL-380 test models of varying inductances and coilconfigurations, using both signal

If I wanted to wind an inductive loop antenna to be connected directly to the PL-360, [no lead wire, no cap] what should the values be for MW and for LW ? - FARMERIK

Just a reminder, hanging a loop from the ceiling, and having a series of attachment points allows you to tilt it without a complicated mechanism. One attachment point hangs the antenna vertical, and a

Operation Python was launched in conjunction with the annual Everglades python hunt. My goal was to log 150 Florida AM BC stations by April 17, the end of python-hunting season. I added several, and

Jim, It's all a bit of a tradeoff. The PL-380 tends to have a fairly high stray capacitance on the antenna, but much of that is in the loopstick itself. I think a well-designed 450 uH inductor will
