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

veines_lowresIn response to my post Tuesday about Arctic DXing in Finland, Per-Einar comments:

“I would like to mention a similar listening site in Norway @70 degrees north [latitude].

Check Kongsfjord.no for logs for reports.

I have observed the same effect DL4NO mentions.  I used to work HAM-radio from Jan Mayen.

On low bands (below 10MHz) its often difficult being heard due to auroral attenuation.

When signals both ways are e.g. attenuated 30dB, its easy to hear but nearly impossible to be heard.”

Many thanks for sharing this. The photos on Kongsfjord.no are simply stunning. I would love to do some arctic DXing at either location (or best, both!).

Have any readers ever ventured to Antarctica for DX?

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

ERT3In 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 (R)

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.

40th Anniversary Montage of ILR Radio Stations

IRL-StationLogosHat tip to Mike Barraclough for sharing a link to this audio/video montage on the BBC website celebrating the 40th anniversary of Independent Local Radio (ILR) with air check clips from stations across the country.

Even if you have never lived in the UK, there’s some serious radio nostalgia in this montage.

Many of these ILR stations still broadcast today, and you can listen to the majority of them via TuneIn radio.

Frank’s maritime radio suggestions

In response to my previous post, The Best Shortwave Receiver for Your Boat or Yacht, Frank (VK3JFH/VP8DNM) writes:

“I have all three of the portables mentioned, the Sony SW7600GR, the Sangean 909X, and the Tecsun PL-660. The latter is currently my portable of choice. Having just read this post re radios afloat I took the time to suck down a fax from Charleville, Queensland.

Results shown..

This was with the Tecsun 660 attached directly to a (near) horizontal longwire at my home QTH, inserted directly into a Macbook Pro running CocoaModem 2.0 via the headphone socket on the Tecsun.
I have had similar results with the Sony and the Sangean

To all intents the result is as good as with my other radios ( K5000 etc.).

However if I was starting from scratch afloat I would get an Icom IC-718. Only $689.95 from Universal Radio. You may choose to simply use it as a receiver or as a Ham TX/RX. However it can also be ‘opened up’ with a simple diode snip to transmit on all the marine bands. Not strictly legal [nor is the IC-718 designed for those bands] but there are a lot of ‘opened’ 718s out there and in an emergency you can transmit a mayday on anything…. even a couple of jam tins and string although you may need a fair old length of string….

If you wish to transmit on your IC-718 you will need a tuner. I have an LDG IT-100 on mine.

Hooking up a consumer receiver to a marine antenna….? Simply make up a pigtail with a 3.5mm jack at one end and a BNC or SO -259 at the other.

Non-marine radios afloat…. ? I had an IC-735 aboard from Cyprus (1992) until Patagonia (2007). Since 2007 I have had an IC-706Mk2G afloat…. no problem with either one.”

Many thanks for your input, Frank!
