Hi Gordon: Greetings from across the bay! That's a neat experiment, almost like a poor man's Q Stick antenna. What type of clear radios do you have a line on?? There is the Sony SRF-39FP (which is

I agree with Zim - a few turns around the radio makes a good coupler, generally as good as a ferrite-based coupler. Perhaps for convenience or aesthetics, you can use one of the cheap AM loop

Unless intentionally comparing radios barefoot as out-of-the box, comparision of relative reception characteristics and perceived audio would be more meaningful if each model used the same wired-in

The simple solution is to wrap a few turns around the radio, with one end of the loop to the antena and the other to earth. To reduce sigs with a big outside antenna, move the loop away from the radio

Hi Jay, Is it possible that your PL-390 is defective? Years ago, my friend and I both bought Grundig Sat 800 radios during a $200 blowout sale. Mine was far more sensitive than his on MW AM, using

Hi Jerry The stock ferrite antenna for the PL380 is indeed inferior to the stock PL310 but the softmute on the PL310 which is more aggressive than the PL380 to me is quite annoying on weak

Hi Sarmento, Thank you for your comments on the Ferrite Sleeve Loop antenna experimentation, and also for posting the details of your innovative portable tuned ferrite passive loops on your web site.

I can't speak to the 7600GR. I've never had one from that line and never had opportunity to compare one to the T615. If radios follow the transitive property, then the conclusion stated would follow.

Just got my PL-390 and I am impressed to say the least. The T615 must be really something if it sucks the pants of one of these! I will never know because I don't think its worth 3X the price. I doubt

hi Michael, i'll be working on them this month to get their write-ups out the door. regards, phil :)

In the spirit of ultralight dx'ing, I decided at 2 am local time yesterday to see if a barefoot SRF-59 could be passively coupled and used to improve the sensitivity of my PL660. Turning the

Nice summary. Anyone in the group play with the bar ferrites? More cost effective? -Mark +++++++++++++++++++++++++++++++++++++++++++++++

I've noticed that some Chinese Sellers (ie Anon) no longer seem to be selling the Tecsun PL 310 just the PL 380 and 390 and many others up to their latest model - the PL 660. With the 380's inferior

Hi Jay, You've got me curious about this. I believe Kevin S. reported that his PL-390 is more sensitive on MW AM than his 7600GR. Your T615 is more sensitive than your PL-390. Does it follow that a

Hi Gary I've been studying your experiments with extremely interest and I confess that it is a very impressive thought, like not only accept maths are the only truth of nature as the classical

I can't speak to the PL-310, but I do have a PL-390. I got a T615 for Christmas this last year. Based on my experience, you already have your bases well covered. The T615 easily recovers audio from

Jerry, Thanks for sharing. Impressed with the reception of the Falkland Islands on 530 kHz with the ferrite antenna. Dennis, Salmon Creek, WA

Thank you all for your input! I had a look at the Tecsun R-911 and R-9012, and i think they look pretty close in specs and functions as my Denver TWR-804, except they have some more SW bands! Thanks a

Hello Jerry, Thanks for your interest in our Ferrite Sleeve Loop antenna experimentation. Although I certainly don't recommend that a DXer build one of these beasts without understanding the

Hi Sarmento! I still have not yet made it down to Brazil again, but continue to experiment with the ferrite bars. I have three bars from Stormwise here in the States: 19 inch, 27 inch, and 48
