Hello all,

A few nights ago during great propagation in the Medium Wave band I had the opertunity to DX Radio Capital from Lima, Peru all the way to Northern Ireland. I was planning to sleep early but favourable conditions on MW prompted me to have a late night to chase DX. I have had this confirmed to me by a few very well known MW DX’ers.

The equipment I had used to get this catch were as follows ;

• Lack of sleep & plenty of caffeine

• SDR Play RSP with ferrite chokes

• Wellbrook ALA1530LN Active Loop Antenna with coax running out of the electric field of my house and ferrite chokes attaches at parts

The Classics Experience with Paul Walker: August 26 and 27

3 Replies

Many thanks to SWLing Post contributor, Paul Walker, who announces his next show:

The next broadcast of The Classics Experience with Paul Walker is going to be the biggest yet. It’ll all take place in late August with 2 hours of rock n roll music with maybe a few country songs thrown in for good measure. The show is ALL about the music and providing something different on the shortwave bands, so all you’ll get from the show is MUSIC. There will be NO rants, raves, personal opinions or political and religious rants. No commercials or sponsors either. I fund the broadcast out of my own pocket so I can pick whatever music I want and not have to answer to anyone but George D. Beagle!

WRMI 7570kHz Saturday August 27th 0400 to 0600UTC. Beaming at 315 degrees towards Vancouver. It should provide a good signal to the West Coast of the US and Canada and probably parts of the midwest and upper midwest along the way.

WRMI 11580kHz Friday August 26th 2100 UTC to 2300UTC., This signal target area is Eastern North America and Western Europe.

WRMI 11530kHz Saturday August 27th, 0200UTC to 0400UTC targetting South America with maybe a little spill over to extreme Western Africa.

WINB 9265kHz Saturday August 27th 0330 to 0530UTC. This should provide good coverage into the Midwest, parts of southern Canada, into Mexico along with parts of Central & Southern Europe it seemed.. It was weakly heard in Australia and New Zealand during my last broadcast.

Channel 292 6070kHz Friday August 26th 2200 to 2400UTC. This should provide good coverage of central and parts of Western Europe.

Shortwave Services 15195khz via Armenia Saturday August 27th 1200 to 1400UTC. Beaming at 65 degrees towards Japan.

I am going to suspend my request for $ to cover postage and QSL costs. I’ve been so lax in sending out QSL cards, I haven’t gotten around to any of them from previous broadcasts and have gotten a few nastygrams about it. I feel bad, so I won’t ask for any money to cover costs this time around.

Contact information for reception reports:
Paul B. Walker, Jr.

Galena, Alaska 99741-0353 USA

There may be MFSK32 data and pictures during the broadcast. I will announce during the broadcast if and when that happens.

Update 4: Sangean DT-160CL v Sony SRF-39FP

2 Replies

If you’ve been following the Sangean DT-160CL versus Sony SRF-39FP battery endurance test, I have some news to report: one of our competitors has finally thrown in the towel…!

Yesterday, while I was on the road for about 1.5 hours, the Sangean DT-160CL at last gave up the contest.

Since I was traveling at the time, I can’t say with absolute certainty what o’clock the DT-160 cried uncle––but roughly, we’re looking at 116 hours, 30 minutes of run time, give or take 30 minutes.

Sangean claims the DT-160 series will operate for 100 hours with two AA batteries. That claim is obviously pretty conservative.

Though I used CVS Max Alkaline batteries (a generic version of Duracell’s Quantum batteries)–an improvement on the standard alkaline battery–I set the volume higher than I believe Sangean or Sony would have set it for testing purposes. This should have drained the batteries faster. The radios were also tuned to a variety of stations: weak AM, strong AM, weak FM and strong FM.

In short: I’m very impressed with the DT-160.

A 116 hour play time from two AA cells on a digitally-tuned receiver is, well, pretty incredible.

Now that the endurance test is over for the DT-160CL, I’ll replace the batteries with a fresh set of CVS Max Alkaline cells and start testing the AM/FM receiver performance.

…And how about the Sony SRF-39FP?

My iPhone’s stopwatch has been tracking progress since last Wednesday.

Even more amazingly, the Sony SRF-39FP is still going strong––!

I actually fell asleep last night listening to the SRF-39FP and woke up this morning with music still in my ears. What a champ!

So, how long has the Sony SRF-39FP now been operating on one AA battery?

At time of posting, this little Sony’s clocked one hundred thirty nine hours.

Though I’ve always known that the SRF-39FP was a true battery miser–one of the reasons it’s been a choice radio in the prison system–I had no idea it could operate this long on one battery.

Of course, I’ll continue tracking the Sony SRF-39FP.

How much longer will the SRF-39FP last? Stay tuned to find out!

New Experimental Radio Station: Skycast (WI2XER)

Many thanks to SWLing Post contributor, Benn, who writes:

[Skycast (WI2XER)] is a station in the Experimental Radio Service, licensed under Part 5 of the FCC Rules.

Benn provided the following details:

Licensed 3 March 2016: SKYCAST SERVICES LLC WI2XER 0809-EX-PL-2015

New experimental to operate in HF bands from 13.87 MHz to 21 MHz to pursue significant advancements in the state of telecommunications technology.

Benn continues:

HF operations in the ERS are rare. I have been following ERS for years.

Applicants in this service are required to describe their experimental program, but can ask the FCC to withhold certain details from public disclosure. That is the reason for the redactions.

The actual purpose of this Skycast is not obvious from the available documentation, but some intrepid investigation may reveal it. SWLs should listen for these operations. The company said that the receivers are in Western Europe.

Experimental stations are not supposed to directly generate revenue. There are occasional exceptions. Most ERS stations are for defense and security related developments, specific demonstrations or academic research.

Readers: please comment if you have any information about this station or its service. Any reception reports/notes would also be welcome!

Update 3: Sangean DT-160CL v Sony SRF-39FP

My iPhone’s stopwatch has been tracking the endurance test.

It’s been one hundred nine hours since I started the Sangean DT-160CL versus Sony SRF-39FP battery endurance test and both radio are still hanging in there!

Not knowing which radio will check out first, I’ve been taking them with me everywhere and have been careful to keep their settings identical the whole time.

Last night, I even prepared my Zoom H2N digital recorder to monitor both radios simultaneously. Having passed 100 hours of operating on the same set of batteries, I was certain one would call it quits last night.

Not so.

There was one noticeable change this morning: the Sangean DT-160CL’s battery indicator now shows a depleted cell.

It’s still operating, though–no noticeable difference in volume and reception.

The end must certainly be near! Indeed, it’s hard to believe I started this endurance test last Wednesday!

I’m very interested to see which pocket radio will go first.

Field time

Yesterday, I spent the better part of the afternoon at Mt. Mitchell State Park. Of course, I brought the DT-160CL and SRF-39FP along.

Mt. Mitchell is the highest point east of the Mississippi river. It’s a great place to play radio.

At one point, I tuned both radios to WAIZ 630 kHz: a 1,000 watt AM station about 95 miles east of the park. It’s one of my benchmark daytime stations from Mt. Mitchell.

Though most DT-160 reviewers have given the receiver low marks for AM performance, I found that the DT-160CL did a better job locking onto WAIZ than the venerable SRF-39FP.

Perhaps this is due to the fact that both radios, at that point, were operating on low voltage? Or perhaps the CL version of the DT-160 series has better AGC characteristics and sensitivity?

I doubt the latter assumption, but once the endurance test is complete, I’ll put the 160CL through the paces.
