Re: Small loop antenna -- Question for Kevin S.
Thanks for the info, Kevin.
Pardon my ignorance, but where does the 90,175 pf*uH come from? Do you have any web sites that discuss this?

Re: Small loop antenna -- Question for Kevin S.
I think that's correct - I must have tied the two sections together to
make a 532 pf lower end. Multiplying inductance times cpaacitance, you
need about 90,175 pf*uH. Since the inductance of the

Re: Small loop antenna -- Question for Kevin S.
Thanks, Kevin.
I believe the coil seller said 365 pF is needed to tune down to 500 kHz. Perhaps your coil needed less capacitance than the one he currently offers.

If you want to see what the finished product looks like, download the
"Using Passive Loop Antennas" article and look for the picture of a little
green box on page 5. I put it into a green plastic

Re: Small loop antenna -- Question for Kevin S.
I wanted a compact set-up, so I used a 2x266 mini variable capacitor from
"zlowe7", ebay item # 150275619877. As I recall I only needed to use one
of the 266 pf sections to resonate the whole band.

Re: Small loop antenna -- Question for Kevin S.
I just sent the coil seller a message through Ebay to ask about making AM BCB and LW BCB coils for the PL-360. Don't worry Gary, I will want the long ferrite model you plan to offer too. If he asks,

Re: Small loop antenna -- Question for Kevin S.
It should connect to the PL-360 as is, and It would be great if he could optimize by making it larger for a little more signal pick up, and offer one for LW BCB. He has a number of choices of wire,

Re: Small loop antenna -- Question for Kevin S.
Thanks for the info, Kevin.
What is a good variable capacitor to use with this coil? Any links would be appreciated.

Re: Terminally ill PL-310 ... or not
That’s the unfortunate downside to theseradios: no warranty. The only hope is that easy to fix issues can be documentedhere so that people can get their radio working again on their own.

Thanks, Paul. Much better than how the vendor explained it, but bottom line ... no change.

Re: Small loop antenna -- Question for Kevin S.
I've seen these in the last few years. Very nice coils. Worth the price just for the wire alone. I didn't realize the Q was over 700.

The Tecsun PL-210 is [u]not[/u] a DSP receiver as listed in the hygt365 auction/offering. See this translated link for added info. It is a bulletin board service for the PL-210 hosted by Tecsun.

The first suggestion is to make sure the words NiMH battery do not appear in the display when using alkaline batteries. The second is to make sure those words appear when using rechargables. Only use

HI TONY,
conditions were tough this morning. i had to listen outside the box:
91.1 WFUM - i heard on 91.2, too much interference on 91.1
99.1 WFRO - heard off the side of the indoors moxon
