Good to hear, Gary! A couple of us here in Lexington KY are following your FSL work, and will look forward to seeing the "addendum" on how to build with the more commonly available ferrites. I have a

Thanks for the info on the 390 but can someone answer my initial questions on comparing the 380 to the 606? I'm really interested in if I can press a button and move up or down in 10 KHz increments,

Gary, Great good news on your FSL upgrade. I am not high tech at alland wonder if these new antennas improve performance on the ShortwaveBands. I listen to international SW broadcast stations

Hello All, The first of the new hard-wired FSL models specifically designed to have an unusually sharp nulling capability is now a reality. With a "short and stubby" FSL design that emphasizes

I didn't notice any performance difference between my 310 and my 310ET, but another thing to keep in mind with TECSUN and similar radios is they are not always consistent over time and from one set

For me, the external antenna input was key. For my use for AM and FM, I see no substantial differences between the older 310 and the ETM. Russ Edmunds 15 mi NW Phila Grid FN20id <wb2bjh@...> AM:

The only reason why one would prefer the 310 over the 380 is the fact it has an antenna socket. I've had the 310, the 310ETM and the 380. The older 310 is sighly better than the ETM

I had both the 390 and 310 and preferred the 310 and liked the 310ETM even better for my uses on AM FM and SW. Never had the 380 myself though. Based on Gary's reviews comparing the 310 and 380 I

Paul... Thank you for bringing he PL-390 to our attention. Although the PL-390 does not do SSB reception, I had an opportunity to handle a new one for about an hour, and I must agree with you...the

Hi Dave, I bought the Tecsun PL390. It is very hot on Shortwave-AM-FM. I was impressed with the way it receives. I live here in Chicago land about 5 miles away from WBBM, WSCR, WGN and I am about 2

Hello Gary and fellow ULR enthusiasts! As some of you may remember, I purchased a Tecsun PL-606, to augment my Eton e-100 and to take advantage of the Tecsun's adjustable bandwidth. Since I live in a

Hello Farmerik (and Alex and Michael), Thanks for your messages. It's probably best to remember that the experimentation to "smoke test" the Si4734 DSP chip to see how much RF it can handle isn't

Hello To All A new addition to the Ultralight Radio Logbook last night 1300 kHz - WXRL - Lancaster, New York 4:20 UTC 1/19/16 w/ numerous Classic Country songs by Sonny James, Ronnie Milsap ,

This explanation was the one which first came to mind. A lot of radios struggle with too much or too little signal :-) Michael Original Message ----- From: Alex winston376 Sounds like AGC

Sounds like AGC circuit 'pumping'. Common when too much signal is presented to the circuit beyond what was designed for. Could also be mixer or IF amp overload. Alex

My understanding of RF theory is pretty limited. Do you think the 'fluttering' is from overloading the DSP chip? If so, would a variable resistor used to cut the signal when needed on some frequencies

For those interested, the first signs of some limitation in the PL-380's Si4734 DSP chip's ability to handle powerful RF inputs from a hard-wired FSL have appeared. In a step-by-step approach to

Hi Guy, <<< Around the same time I also experimented with the nulling ability of ferrite rod antennas using a 3/4" X 18" commercial Stormwise ferrite rod. I'm sure Gary must have tried various

Hi Bill, <<< Thanks for posting the link to your article. In all that I've read about the FSL, I haven't seen any "directivity" comparisons given between the various implementations. Your
