Re: [IRCA] Ultralight Radio DXing Takes Off in Japan

Hi Gary & Nick,
I'm thinking this "hair color" thing could belie one's age, maybe? :) ÂI wasn't even born (for at least another decade plus) when Gary was in high school (or in the service, if I remember right that he served). ÂI just had my 34th birthday this past Wednesday, yet I believe I have a fair bit more gray, as this video - https://www.youtube.com/watch?v=IpUGKb3VjSgÂ- would show,Âthan Gary has. :) Â(My father, who was in college around when Gary was in high school, was mostly gray by his late 30s / early 40s, I think.)
Maybe my early gray has come about from spending a little too much time where the signals aren't so weak? :)Âhttps://www.youtube.com/watch?v=QX5qmaRjXpw
Referencing that first video, am I the only one who has audio pumping issues even on somewhat moderately strong local stations (like 910-KECR in my case)? ÂI'm suspecting it could be because they (as well as 620-XESS and I think 1030-XESDD) could be overmodulating their signal, causing the S/N ratio to pinch off, so to speak.
Also what type of inexpensive more-compact antenna should I build that would get the same gain as that setup, but without the QRN from the powerlines and higher-Q tuning for urban areas? Â(For example, to hear with the internal loopstick the same signal that I heard on 760-KFMB in the 1st video, I have to be at the spot in the 2nd video, which was shot at night when KFMB was operating at higher power.) ÂAn FSL would be way too expensive (unless I could build one AND buy a new SRF-T615 for under the $100 ultralight qualifications price limit), but would one of the PVC loops work, or would the 100Â summer heat here destroy the PVC?
73, Stephen

Hi Nick, 
 
Thanks for your generous comments on the Japanese adaptation of the "supercharged" Tecsun PL-380 model.

Yes, when I told the Japanese DXers that I was a high school student in Japan from 1967-69, they sent me back an email saying that they were only babies at that time. I estimate that they are in theirÂmid 40's-- and they seem to have enough enthusiasm toÂinspire even younger Japanese to join the DXingÂparty :-)

That must be a proud moment in your technical 
career Gary. Â It's always good to see your 
innovations striking a chord somewhere else altogether. Â Congratulations. 

And those Japanese DXers, X, Y, Z -san, seem by 
virtue of their hair color, a little, ah, younger 
than the DXer genus in North America, hi. Â Good 
to see that the Japanese tradition of DX and 
eating / drinking continues. (although I 
understand that some of the Scandinavians are pretty good at that also) 

best wishes, 

Nick
