Scott, all, When I'm DXing, I plug a short Y-cable into the headphone jack. The headphones go to one of its jacks, and the MP3 recorder is connected to the other one through a short cable. Of course,

Yea, of course if I am going so far as skipping lunch, I'll probably just pick up a 360 and live with the 3KHz bandwidth, which should be fine in most cases with a loop that can really null. I have a

Cool. I wondered about that a bit, but haven't experimented with it. My PL-380 is usually connected to my computer with the USB cable, which gives the same effect. So you can try a long USB cable

An interesting development. While doing a band-scan with no antenna to see what was getting through and how far down they were in strength from with the antenna connected, I started enjoying a

Sounds pretty good. With my transformer, I shorted the primary and did a bandscan. The meter sits right near zero for all but two strong stations, both at the high end of the band. (And that

Jim, I am swamped with work, but vicariously enjoying the hell out of your experiments. In a couple weeks I intend to try a hoop loop, although I'll want to pick your brain a little more on using the

Scott and all, Re-did a couple of MW matching transformers with bifilar primaries. They do cut down common-mode signal pickup. I can short the primary terminals at the transformer or at the loop

Thanks for the comparison. FM radios can be very small. Excluding the antenna, the actual FM-related RF components in the PL-300/310/380 can be fit within less than one square centimeter of circuit

Can small be wonderful for FM Dxing? Imagine a receiver 52 x 78 x 16 mm in volume (Degen DE15). Or a receiver 110 x 69 x 13 mm in volume (Insignia NS-HD01) And compare these to the size of the

Roy, Thanks for the update and photos.

Hi all, I would like to post a couple of pictures showing where the SW switching diode is located in both the G8 and Pl-380. Scott mentioned the function of this diode previously and I meant to post

Gary, There will be a "World of Ultralight" in this week's DXM eventually into print in 3 weeks. Hope it's OK what I "borrowed".... and thanks. Phil Bytheway IRCA Editor-in-Chief IRCA

Scott, Got it! Will do this tomorrow. I see how it effectively shorts interwinding-C through the ground connections. Have been twisting the wires coming off the transformers. It would be interesting

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
