Mexico's Bicentennial Celebration Ceremonies

Stephen Ponder <stephen_ponder@...>
 

Did anybody catch any XE's broadcasting special programming last night?

I totally forgot that last night was the eve of Mexico's Bicentennial Celebration and that Presidente Calderon would be leading the "El Grito" and ringing the "Hidalgo Bell" from the Metropolitan Cathedral in the Zocalo Region of Mexico City.  Bummer!  I had planned to listen around 0500 GMT (2300 Local) to any of the major Mexico City outlets to see what I heard.

Did anybody catch anything of significance last night?

73 and Great DX'ing!

Re: Tecsun PL-210 Red

I don't see any indication that this is a DSP receiver.
None of the logos on the radio indicate DSP as opposed
to previous Tecsun radios. The temperature readout on
PL-3xx radios is NOT related to the DSP chip at all.
And the Si4734 chips cannot be described as "dual-conversion".

On the other hand, the Anon-co EBay ads list the display
information as giving RSSI and SNR readings, which could
indicate DSP functions. Can anyone confirm if these
displays are present? I suspect this is just a cut-n-paste
typo in the ads.

Hello,

So you are saying that the PL-210 does indeed have the DSP chip? This would account for the temperature readout function on the 210 if this is true.

Paul,

I did not get my radio from Anon. The tones are hit and miss...random in terms of frequency and intensity, but the designers are well aware of them and have revealed to me that they are aware the tones are interference comign directly from the DSP chip. As I said the severity and frequency of such tones will vary randomly from sample to sample. If you tune around on AM a bit more, especially in the daytime, I guarantee you they will be there.

I do like the ergonomics of the new model slightly better... specifically the variable rate tuning which seems well implemented. But unless these manufacturers can resolve the AM tones issue which I have on every DSP chip based radio I've tried, it's overall a step backward in my book.

Am I the only one hearing these tones on AM? They are random across the AM dial adn never seem to affect SW...they may afflict a strong signal on 1080 but not a weaker one on 1030 for example. I am in a suburban location with no overwhelmingly strong signals to cause overload. When I was checking out G3's all three had these tones on AM but the best one almost inaudible on most signals while one was mediocre and one was horrible so I know it's in the radios themselves.

Puyallup, WA Ultralight TP's for 9-16

Gary DeBock
 

Hello All,
 
     The TP propagation doldrums continued for a second day here, and it was a scramble to find decent Asiatic audio. An indication of the poor conditions was the failure of 1566-HLAZ to produce audio here, for the first time in all of September. The morning wasn't a total waste, though-- there were a couple of bizarre TP fade-ins that were completely out of character with the poor propagation,  providing a reminder once again that strange things can happen at any time in this hobby.
     594-JOAK was the first to produce audio at 1325, but it was poor at best. 828-JOBB was the same way at 1327, refusing to stick around. Then suddenly 648-VOR (of all stations) faded in at a fair level with Russian music at 1329 during the Chinese program, stuck around for a minute, then dropped out completely. Shortly after that the 1053-Korean Jammer did the same thing at 1335, producing a fairly strong buzzing signal, as if to make a point. Various other TP's on 657, 738, 747, 972 and 1134 produced threshold audio, but nothing like these two overachievers.  All things considered, despite the lackluster propagation, it was a strangely interesting morning.
 
     The following were heard on a C.Crane SWP Slider model (7.5" loopstick) inductively coupled to a 9' sided PVC tuned passive loop (in the rainy back yard):
 
594  JOAK  Tokyo, Japan  Poor audio at 1325, but practically ghostlike
648  VOR    Razdolnoye, Russia  Very strange fade-in with music during
                Chinese external program at 1329; unusual strength for the poor
                propagation http://www.mediafire.com/?4qrf4egkqx61qaw
738  BEL2  Penghu, Taiwan Threshold audio in and out throughout morning
747  JOIB  Sapporo, Japan  Another NHK "big gun" reduced to weak audio
828  JOBB  Osaka, Japan  Threshold audio around 1338
972  HLCA  Dangjin, S. Korea  Very weak Korean speech at 1341
1053  Korean Jammer  Once again producing fair buzzing during fairly
                 poor propagation http://www.mediafire.com/?45scruhjsms73h0
1134 TP-Mix  Very weak mix above the noise level at 1343, apparently JOQR-KBS
 
73 and Good DX,
Gary DeBock
657  Pyongyang, N. Korea  Threshold audio from rough carrier at 1338

Hi Brian. SWLs have used this around there rooms where they cannot put an antenna outside and the landlord visit there room or flat.
The idea of a MW BC band loop sound good I would think 24" x 24" in spider web layout should be fine or even bigger, make sure you get the end clips to connect up too, of course it's fairly close to a printed circuit board loop isn't it.
Best Of luck and I hope we get to see a picture. Mike MBR UK.

Should the answer be no, then you are several hundred dollars richer !!!!!
I have been chasing up ' Mobius windings ' on the Internet since reading about the Pixel,
some of the findings cover radio others more of a party trick with lengths of paper !!!!
My current project is playing with loop antennas octagonal in shape made from PVC tube
with a conductor made of cooking foil ( turkey grade !!! ).
Also to hand are several rolls of adhesive backed foil alarm tape, 12mm wide, I may try
a PVC frame antenna in the spiral wound mode using it.
The outside antenna is a 138ft horizontal loop in a diamond configuration, used on
the amateur bands from 80m - 10m and very successful with 5 watts of power on SSB.
