Phil, do you post your single tube(valve!)/transistor designs anywhere? Or do you know of websites that feature this aspect? Some would doubtless even fit the uldx dimensional requirements! Michael

Hello All, For the past few weeks several of us have been conducting detailed experimentation on large-scale FSL models (8" and 12" diameter), in a serious effort to discover the advantages of this

Should be getting on by the middle of this week. could not resist.

I love it--not a URL but otherwise just like the 380 feature-wise but with a considerably longer and more sensitive ferrite bar antenna

Speaking of the PL-390 I was wondering how you like it? Big Al N0CEK

hi Gary! i like the 4 kHz filter; offset-tuned by 3 kHz. yes, a slow-AGC is a big help. i agree, the DSP filters are nice. i use my PL-390 as a spotter. i am pretty hooked on designing single

Phil, What I meant to say is that the S/N meter doesn't work when offset tuned. The RSSI meter still works in this case. I tried using offset tuning with my PL-380 last night on SW. For me, the best

Sorry, I meant the ferrite sleeve antenna. Steve

Hello to All, Propagation from Europe last night was predominately Spanish stations as per logs below. 1 new station was added to the ULR log as BBC Ulster 1341 was either off air for a period of

thanks Gary. guessing: the signal meter may look in a specific region for the carrier amplitude. that's how my FFT-based program, PhilSCAN, worked. regards, phil

you're very welcome. yes, they are similar. and the ergonomics beat the DE1103. the problem with some radios is the quality control. i was going to get a D96L. but Kchibo seems to lack US

Hello Keith, from another Keith,  I don't have hands-on experience with either of those two radios, although I have heard good things about the Grundig. However, I expect you may find WBAP 820 a

Thanks, Phil. I especially enjoyed your article "Si4734 Offset Tuning." I'm going to give these techniques a try on my PL-380. It's too bad the signal meter isn't functional when doing offset

Steve - Are you referring to the Ferrite Sleeve antenna, or just a regular ferrite loop? I've fiddled with both and although I haven't managed to construct an FSL to some of the specs that other

Hello to All Decent propagation last evening considering the higher solar K index reading at 3. Once again some strong signals at near local levels through the later evening. A few more domestics

Phil, Thanks for the great article! (2011 Buying Guide) Do you find that the older Grundig G5/Eton E5 pretty much performs the same as the DE1103? I still have my G5, and was wondering where it

Has anyone got any further with testing the ferrite loop antenna? I have just rediscovered the original article and wondered if it was worth building. Steve

Hi guys! Today I added 10 new article. Some may interest the group: a 2011 Portable Buying Guide, DE1103 help sheet, PL390 help sheet, an Si4831 overview, Offset Tuning the Si4734, and Si4734 Digital

I was hoping to get opinions about two radios. I just bought a Grundig G4000A AM/FM/SW Radio - http://amzn.to/jPWQrK for $70. I read many reviews and it seemed to be the best radio in my price range

They say that we preachers collect Bibles (I have probably 30 of them) and DXers collect radios. UL DXers collect UL radios... For Father's Day, I bought myself a Grundig G-8 at Radio Shack.
