Thanks for the suggestion on turning off the power on each circuit, next time I am home alone I will give this a try.

When I'm tracking interference, I usually cycle through the circuit
breakers, turning off one at a time, in the house breaker box. At
least I can tell if it's in the house or not.

The last time, I isolated it to the garage breaker, then, unplugging
one thing at a time, found it was the cable TV provider's box outside
(Verizon FIOS ONT)- not the power supply, the actual converter box.
Swapping in a new one didn't fix it however, so now I just turn it
(and the garage door opener) off if I want to dx.

Re: Batteries

Paul S. in CT
 

I've been using Rayovac alkalines for 10 years, in that time I have found 1 dead battery, and one weak battery. Otherwise no problems. Using these in a R-911 or R-9012 seems to solve as 2800 mahr at a 5.5ma continuous discharge (Thats 500 hours radio life folks). Higher discharges will lower the expected mahr. In a PL-310 battery life was just over 96 hours continuous.

1.) Alkalines today have a shelf-life of 10 years
2.) Look for "Best used by" date on any package, If you don't see one, don't buy. period.
3.) On occasion that date is on the battery. Thats OK.
4.) NEVER buy an alkaline with less than 7 years future date.
5.) Super Heavy Duty batteries are a different chemistry, with shorter shelf life and "Best Used By" dates. For these be strict about 4 years future time. The capacity starts out at about 40% of an alkaline, and reduces FASTER.

Re: Happy Ultralight New Year (Read at Own Risk)

Paul S. in CT
 

When I joined in May '08, the DSP revolution was just beginning with the PL-310. I had been using a WRX-911 (Kaito) as a spotter for a 1-Transistor DIY contest for 3 years (06-07-08 winters) and had bought an R-911 (Tecsun) as replacement (donated the WRX-911 to my niece). The noise levels back then were more moderate... no electric fences, motion detectors, fewer bad personal electronics, etc. Its pretty tough around here these days... shortwave is a hash-fest rendering WWV nearly unusable, fortuneately CHU 3330 comes in quite good here. AM-MW gets messy, too on the very few open channels remaining (2 I think).

I ended 2020 with 662 unique stations all verified by call-sign.

The effect is worse for rechargeable lithium batteries. Lets leave it at dangerously worse, including fire.

WCPH 1220 Etowah, TN DX TEST-- UPDATE FOR DX'ERS-- IMPORTANT

Les Rayburn
 

 


— LAST NIGHT’S TEST STARTED AN HOUR EARLY ——

George Hudson, owner of WCPH and The Courtesy Program Committee (CPC) of the NRC and IRCA are pleased to announce a special DX Test tonight, late night- January 2nd, 2021. The test will begin at 2 AM Eastern Time until 4 AM Eastern (0700-0900 UTC). 

We have been able to confirm with owner George Hudson that last night’s special DX Test started one hour earlier than scheduled…beginning at 1AM Eastern time (0600 UTC) so if you had overnight recordings running, especially in Europe—please check your recordings for traces of the WCPH 1220 kHz DX Test—you may have a nice surprise. 

According to George—“Sorry for the change. I started the test earlier because I couldn’t stay awake any longer. Long day!” 

:-) 

QSL INFORMATION

WCPH is currently celebrating their 65th anniversary of serving Southeastern Tennessee. The station’s branding is “Homegrown 1220” and “Southeast Tennessee’s Oldies Station.” 

Joe Miller, KJ8O has designed a special 65th Anniversary QSL card, which will be available to those who successfully log this holiday test. If you wish to report reception of the DX test from either tonight or December 26, 2020 please submit your report to the Courtesy Program Committee (CPC) at: 


We prefer an .mp3 recording of the best reception, no more than 2 minutes or so in length. If you cannot record the test, then detailed written reports can also be accepted. Please include time stamps for each element that you received—and describe the content as best you can. 

If you’re really old school—you can send a SD card, USB key, cassette audio tape, or even 1/4” reel tape to: 

Les Rayburn, N1LF
121 Mayfair Park
Maylene, AL 35114

Please include a SASE with return postage. 

Those who are successful will receive a .PDF file of the QSL card, suitable for printing. Please allow 2-3 weeks or longer to process. 
Please only submit one report, even if you heard both tests. 

Also include your location, antenna, and receiver details. The station finds this information very helpful.

Re: Batteries in Series - Different mAh Ratings

Thanks Steve. 
So the smaller cell would die and the larger would still have half it's capacity?

While I have always heard not to mix cell types, what would happen?

For the 1000 and 2000 mAh in series of same type, the rating is for the lowest current one, 1000. The voltage would be double what one cell is.

For the two different types of cells, you should NEVER mix different types, that's forbidden.

Hi all.

Going back 20+ years, my memory of college electronics was that for two batteries in series, you add the voltage and the current is whatever the batteries are rated for. This would mean that 2 x 1.2V NiMh cells @ 2000mAh would give you 2.4V @ 2000mAh.

My question is what happens if you have 2 x 1.2V NiMh cells, one @ 1000mAh and one @ 2000mAh in series, do you end up with 2.4V @ 1500mAh or is it not that simple? What if one was a NiMh cell and the other was an alkaline cell? I am trying to work out and issue and I think this might be a part of it.

Fun for the new year...

Happy New Year Phil (and Paul, Keith and All),

Phil, it sounds like your PL-380 might have one of the external ferrite coil leads disconnected from the RF circuit board. The PL-380' circuit board connection points for the loopstick are kind of flimsy, and subject to problems like this unless the Litz wire is soldered very carefully, with minimum heat and solder,

The weather is icy, the snow is quite deep...

The TA's and TP's have fallen asleep.

The bands they are dreary, the Asians are gone...

The current conditions provoke a big yawn.

But deep in our hearts, we know there is hope..

A new day is dawning, no reason to mope.

We hold in our hands the key to success..

A tiny receiver that banishes stress.

It warms the winter like cookies from Mom,

And zaps IBOC gloom like a nuclear bomb.

It nulls all your pests, eats locals for lunch...

And of all of your toys is the best of the bunch!

When winter is over, and spring shall appear..

We all know DXers will jump with great cheer.

For tiny receivers will lead us to joy...

And make us all feel like we did as a boy.

We may not be young now, and over the hill..

But these tiny toys still provoke a great thrill.

The Club, it has hope now, the future is bright..

Happy New Year to All... with a new Ultralight!

Ultralight Radio DXing Session - 1/1/2021

Paul Blundell
 

Date: 1/01/2021
Time: 9:30 AM 
Location: Home, Launceston Tasmania
Notes: A mid-morning session at home. A good mix of Tasmanian and Victorian stations were logged to start the New Year. A couple of the 50KW power house stations hit excellent signal levels. Again the HPON stations were the only standouts at the top of the band, most other stations about 1000kHz were weak or average at best.
