Newfoundland Ultralight Mini-Dxpedition @ Old Perlican,Newfoundland Dec 18-19

Allen Willie
 

Hello To All,

This past weekend Dianne and I headed out to Old Perlican ,Newfoundland for a pre-Christmas get together with family where we once again completed yet another mini-Dxpedition using the ultralight machines.

This time propagation was very similar to the last time we were out, in that Trans-Atlantics signals really didn't materialize again and the night's activity quickly changed to chasing domestic DX.

Dianne added 7 new stations to her totals and I logged another 8 new ones plus one new state … Oklahoma. With the new additions to the log I finally reached the 500 stations heard mark on the ULR's


Here are the completed logs below of what was heard.

Receivers: SRF-M37V & SRF-39FP barefoot

Good DX

Brian
 

Kevin,
         Thank you for the comments and comparison.
It was an emotive subject for me trying to get a DT-400W after joining the ultralightdx group
none of the companies I contacted in the US wanted to sell me one.
Their answers ranged from too expensive to ship to it will not work in the UK !!!!!
One Canadian company offered me one at $59 plus $79 shipping hi!
Eventually via the kindness of a group member I had one brought over by hand from the US.
Along the way Sangean HQ told me sadly they were not allowed to sell in Europe.
The whole business seemed an odd sales strategy, any way I got one in the end.
                                                     Regards,
                                                        72, Brian.

Hi Brian:

It looks like the Sangean DT-250 is the Euro version of the DT400W:
http://www.amazon.co.uk/SANGEAN-SG0033-Sangean-DT-250-pocket/dp/B001F4ZWKS/ref=sr_1_1?ie=UTF8&qid=1292862462&sr=1-1

It's silver rather than yellow, has no weather band, and presumably has full 520-1710 coverage when switched to 10 khz spacing.

I obviously somehow misinterpreted your comments regarding the Tecsun.
When I was trying to buy a Sangean DT-400W and contacted Roberts about their

All a bit odd hi!

Re: White Noise PL 606

Kevin Schanilec
 

I just got one of the Koss equalizers, and they too introduce white noise, in fact noticeably more than the radio. Again, the little headphone volume control on the output of the equalizer takes care of it. And yeah, shipping the PL-606 back to Joyce would probably cost quite a pretty penny.

I just tested my Tecsun DSP ULRs. The PL-300WT, PL-310, PL-380 and PL-390 all have about the same amount of the white noise at low volume levels, while the PL-360 has noticeably more (presumably because it has a somewhat lesser audio stage). I don't own the PL-606, so can't say where it falls in the pecking order, although I suspect strongly that it is like the PL-310 et al.

Using the headphone attenuator, all of them (the PL-360 included) needed about 75 ohms of attenuation before the white noise was basically gone. So, it is a cure-all from that perspective, and would be my recommendation rather than shipping the PL-606 back to Joyce.

Hi EF,

My Tecsun PL-606 review unit doesn't have the white noise problem you
described. Even with very sensitive headphones plugged in, the volume control
can always reduce the audio level completely down to zero, on all bands.
None of the other PL-606 owners (three that I'm aware of) have reported the
problem, either. Sorry about the inconvenience, but even though Tecsun
generally has a good quality record, not every model comes out trouble-free from
the factory. You might consider asking for repair, or an exchange.

Roberts are an old, established British Radio manufacturer. These days they don't manufacturer their own radios, they sell re-badged Sangean Radios. Roberts and Sangean are not the same company.

Re: White Noise PL 606

Kevin Schanilec
 

Hi EF:

I too hear the white noise - my high-frequency hearing is still quite good, so I am very sensitive to it. I hear it on all of my ULRs to one extent or another, and even on larger portables.

Fortunately there is a cheap and effective fix for headphone use: a volume attenuator, such as the Radio Shack model:
http://www.radioshack.com/product/index.jsp?productId=2102975
There are dual 470 ohm potentiometers in there.

By adding some attenuation and then turning up the radio's volume a couple more notches to compensate, the white noise is gone. There are apparently two reasons: one is that the radio's volume is much higher above its own noise floor. Also, my forays into audiophile-dome indicate that part of the problem is that many headphones have low impedances, which also leads to the noise; the attenuator adds a bunch more impedance.

At any rate, I now have 2-3 of these headphone volume attenuators here at home to make sure I can find at least one of them to listen with, and couldn't live without them. Since they have a very fine degree of control, I also use them to cut the volume wwaayy low when drifting off to sleep with ear buds on, and also to provide the proper signal level for recording into my little Olympus digital voice recorder (which would otherwise distort when fed through the MIC jack). I also use one to pipe the radio's audio into a nice 3-piece computer speaker system.

If the speaker also has the white noise, prying the case open and placing a small-value resistor in series with the speaker may do the trick, mimicking what the headphone volume attenuator does.

Hope this helps - Kevin S

Re: Filter width on DSP radios

Russ Edmunds <wb2bjh@...>
 

As Kevin points out, the 10 kHz spacing isn't really relevant. In any given market, spacing is almost always 40 kHz between stations. Regionally, it can be 20 kHz., however at the kinds of distances involved, it could be ten and you probably wouldn't notice that extra 0.1.

Not sure how/why the FCC chose 5.1 khz - perhaps they were planning ahead to make AM IBOC untenable :-) It seems like stations are generally 20 khz or more apart in a given geographic area, so letting a station bleed 0.1 khz into the next adjacent channel isn't a big deal.

Canada's MW band has always been less densely populated than the US's, and with more and more Canadian stations going silent, any adjacent channel interference is likely pretty minimal. The FCC went from 10 to 7.5 to 5.1 khz audio as the US band swelled with new stations - it may be interesting to see if they loosen it back up again as stations go silent???

Hi Guys:

I did a little Sunset DXing tonight and have a Logging of a Classic Country Station on 1450 Khz.............

The suspects I can see that would fit the bill are........

WNBY Newberry, Michigan...this is who I think it is......

WFTR Front Royal, Virginia

WREL Lexington, Virginia

WCOL in Cornelia, Georgia was disqualified as I checked their Live Feed and it was not them.

I believe it may have been WNBY...but of course they don't have a Live Feed, or much of a Webpage I could check.

I wonder if there is anyone near WNBY in Newberry, MICHIGAN that can confirm the Quasi-ID heard several times as outlined in my Log below????

Re: Filter width on DSP radios

Hi Marc:

It's coming from 740. Broadcast signals are dual sideband, meaning that there is essentially identical information on both the upper sideband. US signals are required to fit within a 10.2 khz total bandwidth, meaning that it extends plus/minus 5.1 khz on either side, thus "sideband". As a result, treble response is basically limited to 5.1 khz (it used to be 7.5 khz, and still is in Canada, which is why some Canadian stations sound a lot better IMO)

In the case of a domestic on 740, their lower sideband extends between 735 and 740, meaning that a TP on 738 is being severely trounced upon. However, the 738 itself has a lower sideband from 733 to 738, so tuning down to 737 or even 736 gets you farther away from 740 while listening to 738's lower sideband. There will still be some of 740's lower sideband mushing things up, but it will be diminished compared to tuning to the TP right on 738.

Hope this helps - Kevin

DSP radios, so kudos to Murata for still having the best filtering. For
instance, listening to 738 under a domestic on 740, the Murata has less
slop when the receiver is detuned by a khz to 737. So, the 1 khz DSP
setting might be better compared to a 2.8 khz "regular" filter - still
pretty darn good.

I am not sure is the slop coming from the 740Khz station, or is the slop
coming from the detoriation of all signals?
