Mike gives the Sangean PR-D15 high marks on AM

SWLing Post reader (and my good friend) Mike Kitchen writes of his new Sangean PR-D15:

The Sangean PR-D15

Having had the Sangean PR-D15 radio for about 10 days, I’m developing a respect for it.

With what I’ve learned in its use, there is a simplicity in operation that many should enjoy.

The big feature for a radio that I really must insist on, is being able to plug this radio into 12V DC with a power supply plug. And this PR-D15 has this capability. I am using a 12 Volt DC, 12 Amp Hour battery as power supply to this radio. Digital displays and their illumination can really eat “AA”, “C” and “D” battery power, and using a 12V Gel Cell, AGM or auto battery allows many, many hours of listening.

Th Sangean PR-D15 uses a 200MM Ferrite bar internal antenna. So far, after about 25 hours of AM DXing alone (not including daily AM use), I’ve learned this radio can really hear!

In a few days, I’ll do some side by side reception tests with the PR-D15 alongside my CCrane CCRadio-SP twin-ferrite analog portable radio. And then, more side by side’s with a CCRadio-2E, the Enhanced version.

Mike, I look forward to your future radio comparison with great interest! The Sangean PR-D15 sounds like a keeper.

Video: Tecsun PL-880 vs. PL-660 on a local AM station

In the following video, I have tuned both the Tecsun PL-880 and the PL-660 to a relatively local AM station (880 kHz). Note that I had the tone control switch set to “bass” on the PL-880 (it would have been better on “treble”):

For normal AM radio listening, I believe the PL-880 produces better audio fidelity than the PL-660. I will try to record a weak medium wave station this evening, if time allows.

Arctic DXing: Norway style

A few years ago we mentioned Mika Makelainen and Jim Solatie, who make a DXing pilgrimage each year to the most northern region of Finland for two weeks of DXing bliss.

The small cabin is very remote, but connected to 14 wire antennas and contains all of the necessities one needs for serious, long-haul DXing. Indeed, they even rent their cabin to other DXers.

I was happy to see Mika and Jim’s annual DX trip recently mentioned in the Xinhua News. Check out Hunting for radio signals near Arctic Ocean, an article by reporters Li Jizhi and Zhang Xuan.

Voice of Greece has become a relay of Radio Station of Macedonia, ERT 3

In response to my post and recording yesterday, TheGreekRadio.com commented on the current state of the Voice of Greece:

“After the forceful eviction of the redundant ERT employees from the Radio House in Athens, the shortwave frequencies no longer transmit the normal program of Voice of Greece as there is no such service produced in Athens. This happened on the 7th of November, when you probably noticed the station ID change.

Mediumwave and shortwave frequencies have been now set to relay the radio program of “Radio Station of Macedonia” by the redundant employees of ERT3, from Thessaloniki. (This used to be the independent program relayed for a few hours before midnight on 7,450 until June’s ERT switch-off, when phone lines were cut and the “guerilla” program started). They keep doing a full program during the day, but being unemployed, it seems that they cannot carry on overnight.

The official interim public radio (one single service for entire Greece) so far does not care for [the take] over [of] the shortwave and mediumwave resources in Athens. Probably they do not have the staff to operate them, as only the necessary personnel was hired to keep the single radio service running on FM.”

Many thanks to TheGreekRadio.com for this informative explanation.

Thus it looks like VOG’s shortwave service might be easily cut–and without warning. We already know that the Greek government is considering dismantling the Avlis transmitting site.

FCC championing change that could “Bolster AM Radio”

FCC Commissioner Ajit Pai

It appears that FCC Commissioner, Ajit Pai, is pushing a plan to revitalize declining AM radio station and listener numbers in the US. Read some of the details below or the full article on the New York Times website.

Many thanks to David Goren for the tip!

The [The Federal Communications Commission] announced late Thursday that it would begin seeking public comment on numerous changes[.]

[…]Because of interference caused by consumer electronics, smartphones and the like, AM radio often seems to deliver mostly static. The AM audience has fallen to 15 percent of all radio listeners, down from 50 percent as recently as 1978. While the FM audience has fallen as well, it draws more than five times the audience of AM.

[Steps include] eliminating a regulation requiring stations to prove that any new equipment decreases interference with other stations — a requirement that is expensive, cumbersome and difficult to meet.

The F.C.C. has also proposed eliminating or loosening rules that govern nighttime transmissions by AM stations. Those regulations currently require many AM stations to reduce their power or cease operating at night to avoid interference with other stations.

[…]The current regulations make it difficult for AM stations to locate towers where they will not interfere with nearby stations at night. They also put conflicting requirements on stations, mandating that they still cover most of their broadcast territory even while operating at reduced power.

The proposed new rules, the commission said, aim at keeping more stations on the air at night.

[T]he F.C.C. said it was ready to make available to current FM stations what are known as FM translators — empty spots on the FM dial where AM stations can broadcast. Those are particularly valuable in urban areas, where tall buildings with steel frames or aluminum siding can block AM signals, degrading reception.
