The thing about this ULing, I have found, is I am listening to a whole lot more religious talk than I ever did in my agnostic life. (And a lot of political screamers that I had always avoided because as a journalist, I believe a story has more than one side.) They do seem to be the most powerful stations on any frequency and, like Hebrew National hotdogs, answer only to a higher authority. 

The Hondurans would be a nice catch. I have a lot of trouble figuring out the IDs in Spanish, though. I sit on a frequency and they go into their TOH or BOH patter and I never do know when they are giving a call sign. Even the US stations I find are pretty lax in identifying in English anymore. 

I caught one this morning, though, WMET 1160 in Gaithersburg Md. that went nearly the entire hour before giving an Engish ID. I needed the SAT for this one, it's a pretty long haul for late morning. There was lots of patter between songs that probably would have provided a clue. But the music was fun.  I guess I'll have to do a little Rosseta Stoning or be content to rule out half of the bandscans.

Thought I had a good one by nulling WSM 650 in Nashville, at 1045Z. In normal conditions, even nulled they are strong here, but today they just about disappeared, and up poppsed a man and woman speaking Spanish. A check of WRTH doesn't show any strong Mexicans on 650, but there are a couple in Honduras, and the signal peak agreed with that. Worth following up, when WSM isn't too loud. Had a probable Mexican playing music on 700, under the weakened WLW, but couldn't get an ID.

What will tomorrow morning bring? (For some reason these early mornings were easier 45 years ago.)  Sunrise (and pre-sunrise -- sunrise here is about 1150Z this week) is more interesting here lately than sunset. ULR total now 334.

Re: MI LOG F I N A L L Y ! ! !

Yea, I have that problem with a few local pests who bleed over adjacent frequencies. It's not in the receiver selectivity either, it happens even on my R8A and R-390A with its mechanical filters. The stations are just sloppy at the transmitter site, is my guess. One of the top FCC Engineers, the guy who ran the school for FCC engineers, used to live here and I got to know him pretty well. One night the two of us went out on a DF hunt for outlaw CBers in his specially equipped FCC car with direction finding antennas. It was a blast. I wrote the story for my newspaper and also wrote a version for Monitoring Times. Anyway, when Jerry was around, he'd keep these commercial folks honest. Alas, he died of a brain tumor some years back. A techie to the end, he was one of the first to use gamma ray surgery on his tumor and even invited the newspaper to come along for this ride. Unfortunately, I was an editor by then and couldn't get the medical reporters interested. What a waste. This was a patient who actually understood the electronics involved in his attempt at a cure. They got the tumor alright, but it had already spread. Years later, one of my cousins developed a brain tumor and underwent the same "surgery." He's doing fine so far.

Re: Ultralight Awards Program Update

Gary DeBock
 

Hi John,
 
Thanks for your question, and of course you may submit new Ultralight Award applications after changing locations, and starting over. You may even submit applications for successful DXing during a vacation to a remote location, as far as I know. Rob and I certainly want the Awards Program to be as user-friendly as possible, and hope that it will motivate all of our group to really "push the limits" in ULR-DXing.
 
As far as "starting over," I guess many of the TP-DXers (both traditional and ULR) are kind of starting over in a way, after John's sudden accident. But we feel that the best way to honor him is to continue following his example of unselfish service to others, and continue DXing (and related experimentation) as he would do himself.
 
73, Gary

Thanks for the interesting report, Tony. Here in South Florida, 555 is dead quiet, and the ghost of Dr Scott was barely audible a while ago. The Europeans are barely audible as well. Pretty good propagation up the coast at sunset, though. If you're hearing Spanish on 1610, spend some time on them. Other than CHHA, a multicultural in Toronto, and a 250-W daytime Mexican station, everything else is either a TIS or deep into South America. Argentina and Peru, for example. WRTH lists a R Reloj on 1610 but it's inactive. I have the Beacon and CHHA here now (0125Z), but nothing else.

Tonight's a good night for DXing Latins, folks. Good luck!

Some new Cubans, and a surprise

jim_kr1s <jkearman@...>
 

Operation Bay of Sigs continues. There are 76 Cuban stations in the log (23% of my ULR total) or, as Glen Hauser would say, I have reached the semi-sesqui-centurian-plus-one level. Not sure the last 24 are possible from here, but braced with 8 oz of espresso I hit the beach, err, band at 1000Z today. That's 5 a.m. local time. This coincided with sunrise over Guantanamo, eastern Cuba, and the plan was to catch some daytime-only Cubans as they came on the air. Last night, map in one hand, WRTH in the other, I plotted a few, east-to-west, by province. Operation BoS does not lack for planning! It paid off, with two new R Rebeldes in Guantanamo province right away on 550 and 580, and a R Progreso in Santa Clara on 680 and a R Sagua (after the city of Sagua La Grande, birthplace of former U.S. senator from Florida Mel Martinez) in Villa Clara on 1540 a while later.

But something else turned up as well. The ubiquitous R Enciclopedia was missing from 530! In its place could only have been a U.S. propaganda station, perhaps airborne. Here's a short recording: http://kearman.com/images/530-022510-0958Z.mp3  I'm counting this as a logged station, but not for any geographic location, as it was probably an airplane. It faded into the noise about 1027Z; when I checked 530 later, R Enciclopedia was booming in.

As usual, PL-380 with modified internal loop, not that you need a great antenna to hear Cuba from Florida! The espresso maker is by far the more-useful accessory.

The same does not seem to be true with TP's on the east coast, which

Yeah, but Saudi Arabia and UAE are about as far from the East Coast as
Japan is from the West Coast, and they count for Asia. Then we have Europe,

Re: Hacking the Si4734: two more PDFs

Roy <roy.dyball@...>
 

Silly Me

Thank you Scott for alerting me. The G8 I used to transcribe the circuit from was the one that got the giant EMP. The K16 I tested must have been damaged making it look like an NPN transistor when I tested it with my analog meter.

In fact it is actually a 2SK238-K16  N Channel FET. If you look at the PL-380 on the bottom of the board with components listed in a Square. Here it lists Q1 Q2 as a 2SK238 which is the 3 legged equivalent. The ICF7600GR also uses this device in the front end. I have redrawn the circuit.

Cheers Roy.

Re: Hacking the Si4734: two more PDFs

Wow! Nice bit of work Roy. I see you've drawn it sort of in the style that it's laid-out on the PCB. I'm a little confused by the circuit at Q1 and Q2, however. I think that those may be PNP transistors, which then makes some sense to me. They would be configured as common-collector stages, i.e. emitter-followers, buffering the high-impedance whip antenna.

The marking K16 matches these parts:
http://www.rohm.com/products/databook/tr/pdf/dta144gua.pdf
which are PNP "digital" transistors. I'm assuming these are surface-mount devices.

Thanks for drawing it all out! I love to learn about all the ways radio designers do front-end circuits.

Hi Phil

I took the time to draw out the G8 front end. The PL-310 and PL380 are
similar but with more components in the filter. The same is true for an
02-2010 model PL-300 which has a redesigned front end/audio board
compared to the original G8. Feel free use the diagram if you want to.
