Hello To All,

A good morning for hearing statons from the south as 3 new stations were added to the Ultralight logbook including a new country , which also becomes my 800th station heard. The two stations on 1070 logged were heard an hour apart, the sunrise has a wonderful effect as the time goes by.


1320 - VENEZUELA - YVWT - R. Apolo , Tumaro 7:39 UTC Sep 6 Spanish talk , ID by man , possible Jingle ID on fade as well ULR Station # 799

1070 - EL SALVADOR - YSAN - Ahuachapan 7:54 UTC Sep 6 Spanish talk, many mentions of El Savador and San Salvador , expressive man with "El Salvadoooor" ULR Station # 800 ***NEW COUNTRY *** #89

1070 - COLOMBIA - HJCG Radio Santa Fe , Bogota 8:54 UTC Spanish vocals, man in Spanish ment. Colombia , nice clear ID also "Radio Santa Fe" ULR Station # 801


Receiver: SRF-M37W barefoot


Good DX

Good bye and thank you

I have made the decision to leave the ULDX hobby and as such I am selling off all my gear.
If anybody is interested in it I have a link to my eBay auction below.

http://www.ebay.com.au/itm/290771161871?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649

I have really enjoyed my time on here, getting to know some of you and learning about this hobby, in the end other interests have taken over and while I do enjoy this hobby I don't have the time or motivation to really get involved with it.

Re: CKGM 990 Montreal Heard Testing on 690

ferrite61 <dxrx@...>
 

I can hear CKGM on 690 in the small hours this morning. Canadian ads for Tim Hortons, and PSA's using dot ca EMAIL addresses. Seems to be Canadian branded "ESPN". I've heard the change went live Sept.4,2012, so this morning's 0120EDT catch of sportscenter might be an RX for the log. Not sure of power rating or directionality at night. RX noisy with static (lightning presumed) sounds a bit weak for 50kW, but they may be firing more E-W than N-S.

Hello All,


Heard CKGM 990 Montreal testing on their new frequency of 690 this morning , the official switch over on Tuesday Sep 4 according to reports.


690 - Testing of CKGM 990 Montreal 6:32 - 6:50 UTC Sep 2 with NFL Talk, Olympic talk about Canada & Basketball team performance , then "You're listening to 990 CKGM testing on 690" email given for any interference caused by this to send to , then into NHL talk (Signal good on this frequency at this location)

Ironically , one of the few times I couldn't at least hear them on 990 as well . Most nights they are audible under CBY Cornerbrook and occasionally are heard over top of CBY on 990.

Re: Tecsun PL-600 Birdie

Sorry for that. I learned something new about a radio I have
owned for years (the DX-440 being double conversion). I just
assumed it was single because almost all double-conversion
radios list that on the case to help sell the radio. The 440
certainly does not have much image rejection when tuning LW.

Re: Going Linear...

Bruce Conti
 

If unable to shut off the noise source, I would consider going "ultralight unlimited class" by coupling an outdoor terminated broadband loop antenna to your ultralight radio for DXing from the comfort of indoors.  The loop can be located at the quiet spot on your property with a noise-reduced lead-in to your radio shack and RF transformer coupled to the RF inputs of the radio (or alternatively with a few wraps of wire around the radio although that may also act as a in-house noise pick-up).

Terminated broadband loop antennas such as the Delta, Flag, and SuperLoop are easy to build, basically consisting of a single loop of wire with an in-line termination resistor and an RF transformer coupling to a lead-in.  Example drawings are available at www.bamlog.com in the Antenna section.  An internet search for "Delta antenna" etc. will find more info.  These antennas produce a wide cardioid beam with a deep backside null.  The null of the antenna can be aimed to further reduce noise while the terminating resistor can be adjusted to the desired deepness of the null.

I don't have experience with coupling to an ultralight radio though.  Perhaps others in the group will be able to provide more info if you decide to go that route.

In terms of contests, the NRC contest over last season was a fun one.  It was a series of sprints giving each participant the opportunity to compete in each segment while also offering a cumulative contest.

Re: Going Linear...

GM John- I also have noise on the low end of the BCB. I can track it to the utilities entrance on my house. From there, its pretty much radiated throughout the building. I've also found hot and cold spots in the yard, as you have. Over the years, as things have been added to the place, noises have popped up. Some with addition of computers, wireless router, solar panels/charger/invertor. Changing the style of fluorescent lamps in the radio shed was a bad move here.
The metal roof made a negative impact on a non-augmented portable radio, but using a passive loop helps quite a bit.
Odd thing, my crystal sets do not seem to be as hampered by the always present noise that's on the utilities. I use an approximately 250 long, tee fed antenna over who-knows how many feet of ground screen.
One of the best all around listening spots for me is an upstairs storage area of the garage. 15 feet up, under a metal roof, on a SW facing gable end. There is nothing noise-wise to speak of.
I'd be interested in what you find as the major source of noise.

I have decided to return my PL-505, but I'm still curious about its ability to receive between 1715-2300khz.

Is there any PL-505 user who found this working?

Re: Any groups for mid-size radios?

keith beesley
 

Keith, 

There are many Yahoo Groups devoted to specific radio models: Tecsun PL-600, Degen/Kaito 1103, et al. Just Google "Yahoo Group ___" (name of radio) and you'll find them. To my knowledge, there is no single group that addresses pros and cons of one model vis-a-vis another, it might be a good idea to start one.

"radiojayallen.com" is an excellent site with reviews and side-by-side comparisons of many different receivers, large and small, primarily focusing on the medium wave (AM) broadcast band performance of the radios tested.  

Of course, many of us here also own and use larger radios in addition to the ULRs, so you are welcome to ask questions here, too. 

Regards, 

Keith Beesley

Re: Going Linear...

roberts50000
 

I would concentrate on trying to find the noise source if you
are sure it is inside your house. That is far easier than trying to
track down a noise source outdoors or somewhere down the road
a mile or two.

I would take a look at anything digital or anything that uses a
switching power supply. Many of the older small wall-wart transformer
power supplies are being replaced with small transformerless
switching power supplies today that can throw out a lot of noise.

Any appliance nowadays could be suspect, even a dishwasher,
anything that has a digital clock or keypad could be throwing out noise.
Don't forget battery chargers, light dimmers, fluorescent lights. TV sets,
even when turned off could have some kind of live circuit inside just
idling on low power.

Use your ultralight radio to see if you can find where the noise increases
and go from there. Don't overlook anything, even doorbell transformers
have been known to create strong interference.

Hi John,
 
Try turning off different circuit breakers in your house until the noise disappears.
Then find out what is on that circuit and unplug them one at a time until the noise
disappears.
Don't forget lamp dimmers on wall switches!
 
If that doesn't stop it check when your house was built as if it has "KNOB & TUBE"
wiring it might be warning you of a fire trying to start!!!

I don't consider it an issue. Here in North America there are a couple of Navigational beacons on 450 in the Caribbean - one of which I've heard a few times on a 2010 - but not much else.

Whatever frequency is used as an IF frequency would do the same thing.

Re: Tecsun PL-600 Birdie

ferrite61 <dxrx@...>
 

Most <$1000 radios have this problem... but its not really a problem. You are losing a total of 2 NDB's on 450kHz. The other nearest ones are 440kHz and 492kHz. As I posted earlier, you can use this to center the BFO by tuning 454 and 456kHz and adjusting the fine tuning wheel until the pitch is the same on both frequencies.

I really don't see this as make/break purchase.
