Re: Batteries in Series - Different mAh Ratings

Hunh????

My understanding was that traditional dry cell batteries are Manganese oxide/ Ammonium chloride. No sulfuric acid there. The only batteries with sulfuric acid that I am aware of are wet cell (ie. car batteries).

Help me if I am missing something.

Thanks

John

KSEN 1150 DX Test Report CORRECTION

Les Rayburn
 

Apologies all. Paul Walker pointed out that I was confused about our DX Test sequence and needed to correct my report. 

Attached is a report on the November KSEN 1150 kHz DX Test from Montana. It was one of the most widely heard DX test in decades with receptions spanning the globe. It was also reported in virtually every part of North America.

Thanks to Todd Clark, KSEN, Paul Walker for arranging the test, and Joe Miller, KC80 for designing the QSL card and handling verifications. 

As we went to press, we received a late report and QSL report as well which is included below: 




I would like to report my reception of KSEN from November 8th on 1150 kHz.  My best reception came at 0238-0239 EST when I heard Morse code and the sweeping tones. At no time did I hear any voice announcements. There were four other stations on 1150 kHz which were causing interference, which included WCUE, CKOC, WHBY, and WIMA. This is #1 from Montana from my home in Sterling Heights, Michigan.

Wow Jorge,

1280-CFMB really is awesome ocean cliff DX for such a late time in the morning on the Spanish coast!

To be honest, though, I have personally experienced so many unusual receptions on the Rockwork ocean cliff in Oregon (facing both Southwest to New Zealand, and west to Asia) that I'm not really surprised at these freakish receptions. For example, because of challenging propagation it is extremely rare for any MW station from India to be received on the USA west coast (I think that the last one before October was about 10 years ago, with Patrick Martin's reception of 864-AIR in Shillong). But a tiny 6 inch (15cm) FSL not only provided reception of 675-AIR at the Rockwork 2 cliff in October, but also 576-Myanmar and 594-Myanmar, all on a C.Crane Skywave Ultralight.

I hope you will continue to investigate the ocean cliffs on the Spanish coast, Jorge, especially with Ultralight radios around sunrise. I'm sure that you will enjoy many more astonishing receptions!

73, Gary

   


2021 Radio Challenges and ocean cliff effect?

Jorge Garzón <iberiaDX@...>
 

Hi Paul and others, 
While I was reading your post, a new challenge came to my mind. Something that could be both interesting and rewarding: logging MW stations during daytime: from (local) sunrise to (local) sunset times. That's all! 

Propagation is a kind of mistery (well, in fact not all); the first one and a half hour after sunrise and before sunset can be very, very special. 

Before yesterday I was parked over some ocean cliffs, not the highest ones we have, but about 40 m high. It was 10am in the morning with the sun in the sky, and I was in the car (was windy outside) zapping UK MW stations as they reach the Northern Spanish shore quite well in the mornings. I checked 1278 kHz and I heard quite a strong signal with lounge music. It faded down quickly after 25 sec, but came back a minute later for a minute more, weakest but well audible. After that, dissapeared in the noise. Maybe not the second burst but I am pretty sure that the first and shorter one would have been heard in an ULR/portable radio. I just had the autoradio, regular selectivity, fixed 9kHz steps, small roof antenna, but quite sensitive. 

What I heard? Please, check this: 
https://twitter.com/FMDXIreland/status/1348771038067372035?s=19

And Gary, now I add... Is this a tiny ocean Cliff effect? And yes, the cliff was facing west 🤷🏻‍♂️

73!

The Topazdesigns site is my go-to for station info because it includes
stations in Canada.  I couldn't recall why I used Mesa Mike for this
listing but just remembered - the former won't list ALL stations while
the latter will!   I cut and pasted the whole list into a spreadsheet,
then sorted by Night Power then frequency and chopped off everything
below 25 kW at night (not *technically* throwing flames but I'm more
likely to hear them instead of a 10 kW (only 15 listings with night
power at 25 kW or above and less than 50 kW - 94 at a Full 50 kW).

There was time when WBZ was easily heard in Oklahoma, but it’s difficult now.

Then the FCC started screwing things up and now it’s mostly a log jam.

I have heard WBZ and WABC a couple of times this winter albeit briefly.
Clears are not what they used to be ... and really haven't been in 40
years. :-(

WABC, eh? A favorite when I was a kid ... but I was only 500 km due
north of them then! I shall try to log them ... perhaps whenever
Cousin Brucie has his show.

WABC and WCBS are still there, but WNBC pretends to be "WFAN" ... :-)

3 more dug up, so 35/109. Pretty pleased with that. California is
tough, but I've logged KNX-1070 in LA ... New England and the
Northeast are tough ... but as noted, I logged WBZ-1030 in Boston a
few weeks back.

Thanks for making me dig, Paul B!

I was going to say "some are probably out of reach" and while that is
probably true for AK and HI stations, I did recently log WBZ-1030 in
Boston and I never imagined I'd log them from here in Oklahoma.

Hello Again Jorge,

Thank you for sharing the details of your amazing Ross DX Challenge results, and also for introducing us to your other radio DXing activities as described in your Iberia DX website. 

We are always happy when an experienced DXer like you discovers the unique challenge and thrills of pocket radio DXing. This trend has been going on in North America, Europe and Japan for quite some time, along with some notable interest in Australia and New Zealand. South American DXers seem to be especially intrigued by the ferrite antenna experimentation, and hobbyists around the world now have a new option to enjoy long range DXing excitement.

On your Iberia DX website I noticed that you also have interest in Longwave DXing for distant NDB's (aeronautical beacons). Actually, there is a branch of Ultralight radio DXing that is related to this, where we use Longwave-optimized FSL antennas and Longwave-optimized radio loopsticks to chase very distant NDB's. An example was last summer, where an ocean cliff on the Oregon state coast provided reception of two very low powered New Zealand NDB's   https://dreamcrafts.box.com/s/mj6i4e4sg9j9gd54273nb35gb8r555fo
These were 362-WK in Whakatane, New Zealand (25 watts at 11,017 km) and 366-SF in Springfield, New Zealand (50 watts at 10,977 km). These were received at local sunrise on a 7.5 inch Longwave loopstick Tecsun PL-380 Ultralight radio, assisted by a 12 inch Longwave FSL. This kind of DXing is very fascinating, since the NDB's are continually broadcasting ID's, and you only need to receive one good ID for DXing success.

73, Gary DeBock (in Puyallup, WA, USA)

Just for your knowledge, we call in Spanish "DX de bolsillo" (Pocket DXing) to the English "ULR Dxing". I have worked 47 ITU radiocountries, and I also added a new menu category in my blog called "DX de Bolsillo/ULR DX". My blog is here: http://iberiadx.wordpress.com written in Spanish and some posts also in English. Under that menu category I have updated the number of radiocountries and add a page with audios recorded during the Challenge just to show how I heard some of the interesting stations included in the log. 

I hope you enjoy it!!!

73 y buen DX.
