Re: Tecsun PL-310 vs Sonys?

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.

Re: Tecsun PL-310 vs Sonys?

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

"Why Not?" Experiment

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

Tecsun PL 310 versus PL 380 - Which one to get?

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

Re: Tecsun PL-310 vs Sonys?

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

Re: Tecsun PL-310 vs Sonys?

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

Re: Denver TWR-804, anyone know this radio?

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

They are the real deal--see Youtube search under the term "ferrite rod antenna" for a number of illustrative videos. the key points: use 125 mu ferrite that is at least 10 x > length than width, use

Hello, I've bought one of the "sister" of the PL-310 : the PL-390. So I will speak based on my experience. DSP signal processing does bring a lot to listening

Howdy all, I'm a long time Ultralight DXer in Southern California, aided by my trusty Sony SRF-T615 and 7600GR; I've owned this pair for several years now and haven't seen the need for another radio,
