Re: Early results of 7.5" Amidion rod

Roy, Disconnecting the SW amp is a trivial modification. There is a switching diode that connects the SW amp to the AMI node on the rear circuit board. Just clip the lead on this diode and

Re: Mexican Loggings

Good work Kirk. It is appreciated. During the past 48 hours I've noticed signals from Mexico have dominated the medium wave band here. Last night, normally heard stations in the province

New Article on Adding Antenna Ports to DSPs

Friends, I have just added a new article to the "Antennas &Equipment" section of the Ultralight files. It is calledAdding a MW Antenna Port to Tecsun DSP Ultralights and covers applying my own usual

Re: New version of Tecsun PL-380

I guess so. The Blackberry charger does fine, though it makes a nasty whine on AM. Some chargers really sock it to NiMH cells. I have a Duracell charger that is FAST, but the cells get pretty hot. If

Re: TECH: PL300 loopstick tested (what is Q....)

Hi Richard, Q, or "quality factor", is a measure of theloss of an inductor or capacitor (a reactive component, in electronics terms).The lower the loss the higher the Q. For radios with a tuned

Success in PL-380 In-Cabinet Loopstick

Hello All, Yesterday there was a moderately successful experiment to wind a 40/44 Litzwire coil on a PL-310 stock ferrite bar, which was successful in providing abouta 4 dBu average increase in the

Re: TECH: PL300 loopstick tested

Steve, What is "Q" in simple terms. Why does the 310 have better mw&lw sensitivity despite the lower Q's than the G8? Heatwave

Re: New version of Tecsun PL-380

Absolutely agree with you on the FM performance! Shouldn't any USB charger work? I have a bunch of them and they all seem to do the job. Unlike cell phones, I don't think these radios are looking for

TECH: PL380 stock loopstick tested

Today I checked the PL380's loopstick with the HP4342A Q meter. It's a lot lower inductance, and tunes over the whole MW range. Its Q is very close at MW to the PL310's loopstick though a little less

Re: TECH: PL310 stock loopstick tested

Those results certainly meld with my mw experiences with the 310...below about 900 KHz, it is a very sensitive set...similar to the Eton 5. Above about 1300 KHz, it is much more similar to a Sangean

Re: Early results of 7.5" Amidion rod

Gary The G8 and the Pl-380 have almost identical front end circuit boards. They use the same chip. In both the radios the antenna goes straight to the Si4734 (pin 4) via only a coupling capacitor.

Re: Upgraded Tecsun PL-310 Internal Loopstick-- Moderate Success

Now we're getting somewhere! :) Gary, try spacing the turns as Roy did. That should perk up the Q and might net a little more improvement. Also, have a look at Ben Tongue's paper re using a spacer

I read the post which said the Motorola charger for the RAZR V3 would work on the PL-380 so I tried a charger for an old L6 and it charges the batteries as well. It also runs the radio with or
