Thank you Gil for your answer. The main reason for doing this is to stop the noise coming in via the loopstick so I figured the closed magnetic loop of the toroid would achieve this. A lot of the

Roy, If you are seeking relatively high Q, a toroid is notoriously low regardless of type of wire used. In testing Q in toroids wrapped with solid wire or litz, Q in excess of 200-250 is rare in MW

Roy, Regarding access to the serial lines, the traces connecting to those resistors are available on the back of the board, and I'm not shy about cutting and soldering to the traces. The interface I

Thanks for the info. New Jersey would be a new state for me, so that would be a good one. I'll see if I can get it again tonight. Jeff >>>hi Jeff, on the 1680 in spanish, i copied a spanish

Gary, Following your "Supercharging The Tecsun PL380" article I decided to do the same with my PL310. I made a new 7.5 inch loopstick using the material in the article - Amidon #61 Ferrite bar and

Hi Scott You will have to remove the metal RF shield to gain access to the SMD resistors from the local CPU. Here is another picture to help (G8). Included are the GPO lines and reset. Tecsun hold

yes, that was my take on it, too. These itty-bitty ferrite bars just don't seem to cut it. "Soft-mute" might be an annoyance, but the short ferrite-bars are a deal-breaker for me.

Hi Gary, Thanks for the review of the PL-380. It seems like the PL-310 is a better bet, except for the "soft mute" feature. Perhaps Tecsun will disable the soft mute in the PL-310 at some point in

Hi John With using the G8 and PL-380 in the close vicinity of computers and having got the software up and running it is time to get my little radios able to receive a good clean signal free of

John, Thanks for the warm welcome. I've been reading through all the articles in the file area and at dxer.ca. Looks like a lot of fun projects. Even though there was no Ultralight DX group around

Hi Roy, Thanks for the kind words and enthusiasm. Several of us at Silabs have thought that the Si47xx chips would be very fun chips for DIYers and it's gratifying to see experimentation take

Hello Gregory, Thanks for your interest in the external loopstick modification for theTecsun models, and I hope that we can optimize the sensitivity of your PL-310 toobtain great sensitivity on all

Hello Phil, Welcome to the group, and thanks for your interest in the coil windingtechnique used here in the PL-310 loopstick experimentation. In answer to your question about the type of tape

Scott!!! Let me add my name to the Welcoming Committee. You and the other folks atSiLabs have turned a serious segment of radio on its head! Bravo. Iswear that the 47xx family of chips will go far

Friends, John Cereghin has given us all a Christmas treat. He has produced anexcellent five page article on establishing a series of target lists froman initial sort of the FCC database database to

Hi Guys: I hope everyone had a Great Christmas....and received a New Ultralight Radio in their sock!!! All was great here.....and we had a Blast. No DXing was done however, over the last 3 days...as

Hello All, For those interested in the DXing capabilities of Tecsun's newest DSPpocket radio, a thorough 7-page review of the PL-380 AM-LW-FM-SWreceiver (covering the development, capabilities and

Hello to the group. I have beenlurking here for awhile, as I do in a dozen or so radio related groups. Just as a matter of perspective, I built my first crystal set in 1958. I have somewhere around 40
