Tecsun PP-330 has a great feature

Robert Conboy
 

...not sure if this has been mentioned before...


The Tecsun PL-330 has an external antenna jack. It also has a feature where if you press and hold the “3” button it switches the mw loopstick antenna out and switches in the whip. Then if you plug an antenna into the aforementioned jack, it switches out the whip and switches in the jack.

 

If you plug in a simple stereo plug, and cut off the opposite plug, you can separate left and right wires as much as you need to make a pickup loop. Connect the right channel center conductor (red wire) to the LEFT channel shield. Cut back the left center conductor and right channel shield to prevent you from shorting it out.

 

Right now I have the pickup loop wrapped around my 19-rod FSL. Wow! Clean signal, super easy to tune, and it is not impacting selectivity of the antenna.

 

To switch back to the loopstick, press and hold “3” again.

New Medium Wave Circle Website

Paul Blundell
 

Steve who is the editor of the medium wave news has contacted me to let me know that they have a new website.

Some of the features of the new website are:

  • easy to use membership with secure online payment
  • access to the full archive of MWN (all 500 issues)
  • access to the latest 2020 Editions of the All Time DX Heard in the British Isles
  • a new section for news and feature articles
  • a completely new and re-written library

For the first time we also host the archive of the European MW Guide which was the most complete directory of radio stations in Europe.

 

All the content is either new or completely revised and updated. Most importantly we want our website to be unique and that is why the features, photos, QSLs and audio clips are not to be found elsewhere online.

The new website has been carefully designed to work on desktop PCs, laptops, ipads and even smartphones. It has also been updated to improve security - you will notice the https web address & the padlock next to the url in your browser.

 

Check the new website out here: https://mwcircle.org/

Re: Expanded Band DXing

Paul Blundell
 

Now that we have an active station on 1611kHz here locally, I have been spending more time on this part of the band. With the AR-1733, I have noticed that these stations work best with 3" FSL being placed further away than for stations at the lower end of the band.

I have recently been out this way and have noticed that the signal is not great until very close to the TX site, I strongly suspect that either the transmitter or aerial are faulty. 


My 2nd Favorite AM Log This PasT winter

Paul B. Walker, Jr.
 

My first favorite is obviously 7ZR 936, it landed me on national TV

This was my second favorite, MR4 Nemzetiségi Adások, 1188khz Hungary from Sun Jan 17, 2021 at 905AM Ak time 1805UTC. The signal held out for over 10 minutes. Good thing it was a Sunday morning, still dark and no one was driving that "Early" otherwise McGrathites wouldve seen me excitedly conducting my own orchestra in the KSKO driveway with my headphones on.  (seriously, I was)

Audio:

Thisa same morning I also had 10 or 20kw 1233 from the Czech Republic.

The situation in the United States is not one that would indicate that HD is the future of radio. In the San Francisco Bay Area, one of our two National Public Radio stations has turned it off. The commercial FM stations running HD have been abandoning their HD-2 channels. The all-sports stations on FM (we have two of those) have turned it off - the time delay makes it difficult for listeners to bring their radios to the ballpark or stadium to hear the play-by-play of the action that's in front of them. There are still a couple of interesting formats on HD-2 stations, but in other cities, HD-2 channels seem to be used primarily for AM simulcasts. No AM HD here - the nearest is in Sacramento (about 130 km away). The Federal Communications Commission has authorized digital-only AM stations, but that's a relatively new development. The big commercial chains (Audacy, iHeartRadio, Bonneville, Cumulus) are the ones who've kept HD alive. As for receivers, many new cars can receive HD signals. However, that's not widely promoted. I bought a car two years ago; the "infotainment system" can receive HD but it was turned off by default. I had to go through the menus to find the setting to turn it on.
Mark,

I'm on the opposite coast, and the NY Metro market may be atypical; but HD penetration is still reasonably alive. WCBS-AM turned off its HD exciter a few years ago but WINS-AM is still going strong with both an AM (MA1 mode) and FM-HD3 subchannel. Many of the local corporate FM stations transmit in HD and many have multiple active subchannel streams - as many as FOUR in some cases. Elsewhere I reported on WFAS-AM, a audience-less low-power Cumulus station that switched to all-digital on May 22.

Kinda curious about your experience with car radios (forgive the brief off-topic diversion). Over the last few years we have had Ford and Toyota products (odd pairing, yes - it's because they have thoroughly perfected very similar gas/electric hybrid technology); the mid-level and premium factory sound systems all have HD tuners which is simply enabled by default.

Hi Peter/Paul/Mark,

Super interesting, thanks for the "education", that is very enlightening!

It's kind of weird how this technology of translators has kind of "morphed" over time, providing value to some extent, but trouble in other areas.

I am well within the limits of the contour, in the area of the GW Bridge.

Of course I am reporting to this group with topical preference to the smallest radios that are capable. The HDR-16 does much better as do both our car stereos which have HD tuners.

And yes, that's the problem with digital-only modes; the dreaded "cliff" effect.

As I mentioned the audio on WFAS-HD has an annoying sibilance which I do not hear on the other AM-HD station in the area, WINS (MA1 mode), whose audio actually sounds quite pleasing by comparison. This is me very first logging of an MA3 mode signal; maybe this is to be expected in this mode.

To disable the soft mute, with the power on, push the "Page"button, and while the menu indicator flashes on the display, push the s-mute (#3) button until the desired setting is shown on the display.

The locals (OKC market) *only* advertise the analog FM translator's
frequency and *never* mention their better quality HD signal which is
on a full-power FM. OK, maybe not never, but certainly not every time
they ID. None of this is related to AM stations, of course ... yet.
Will AM stations that go to MA3 advertise that fact on their Analog FM
translator? It's weird.

Never advertise the fact that your programming is *also* on a superior
HD signal so ... what? You can declare HDRadio a failure? It's
weird.

Re: FM Translators - Why?

Mark Roberts
 

The original purpose of FM translators was essentially the same as for TV translators. However, FM translators in the United States were much more restricted. Commercial FM stations can't own a translator outside their service area. Translators of an FM station can be independently established, and the owner of the translator can seek financial support from the originating station, but the translator can't be constructed or operated by the originating station. In most cases, translators have to be fed with an off-the-air signal (though that can be obtained through a CATV connection!). There is a big exception: Non-commercial educational (NCE) FM stations are not subject to these restrictions. Certain religious operators have exploited this loophole (in my opinion, abusing the purpose of translators to start with) to extend their reach nationwide, feeding many of their translators via satellite. As part of the FCC's AM "revitalization" initiative, AM stations were allowed to establish FM translators as long as the coverage of the FM translator did not exceed that of the AM station. Daytime-only AM stations, of which there are now very few, were allowed to continue broadcasting on their FM translators at night. The idea was to get AM stations a foothold on the FM dial where a majority of radio listening occurs and thereby give them a chance to compete. These are referred to as cross-service translators.

Another loophole involves programming originally on an HD (digital) subchannel. Those, too, can be relayed by a translator, giving an HD signal an analog FM presence. This is desirable because HD-capable receivers are not common, except for vehicles.

As for boosters: If you hear one, you probably won't know it. They are on-channel, intended to provide an infill signal for areas where FM reception is blocked by terrain, tall buildings, etc. (I have never heard a legal ID for a booster.) Good examples are the San Francisco Bay Area in California, just east of me in Oakland. On the other side of the 1500-foot hills separating Berkeley, Oakland, and San Leandro from the Diablo Valley (sometimes also called the Tri-Valley, the San Ramon Valley, etc. - essentially the Interstate 680 and Highway 24 freeway corridors and surrounding communities), there are several boosters relaying San Francisco FM stations. Most are on Mount Diablo or on Pleasanton Ridge. While they work, some are reportedly not well maintained. When I've been over in San Ramon and vicinity, I have noticed some multipath interference among the least well-maintained boosters. KITS was particularly awful - but I might have been receiving a badly ghosted over-the-air signal from their main San Bruno Mountain site. It's impossible to tell.

The FM dial was already crowded in many large cities in the United States. In some cities, the additional translators have made it worse. In the Bay Area, there wasn't that much of an effect because our FM dial was crammed with stations already, but a few cross-service translators have been added. One had to shut down because it interfered with a station in Silicon Valley.

Here (Tasmania) they serve two main purposes:
- To provide coverage in areas the main transmitter does not reach. As an example, our main transmitter site for FM radio is Mt Barrow, this provides a great signal across a wide area but as our CBD is in a valley, due to this they have translators in the CBD for our two commercial FM stations.
- In some rural areas, they have a translator of the local AM station to also provide a signal for those that don't have an AM radio.

Hi all,

Why do FM Translators exist?

The closest I can tell is that they exist to give an AM station a "Market Presence" in the FM band at a local level.

Is that pretty much it?  Or am I missing it?

Also, I have not come across an FM Booster yet, but apparently these exist (in the US at least).

Digital is better farther than analog but when it stops being good ..
it stops. Completely.

Analog keeps going farther but the signal is bad enough that only
people that subscribe to this list will listen to it for more than a
couple of minutes.

And that has nothing to do with HDRadio - any digital radio is like
that - P25, D-STAR, whatever.

Their transmitter is about 18 miles from me as the crow flies.

Knowing this change was coming I benchmarked the useable signal on a few of AM-HD capable portables (Sangean HDR-14 and HDR-15, NiceTex "SPARC" SHD-TX2) in analog mode early last month, and then did the same after the conversion. In analog mode the audio was very staticky but as intelligible as any fringe area station. Of course the digitall audio is significantly more intelligible - at the cost of the artificial-treble expansion sibilance characteristic of HD-AM.

The problem is, even with all of the transmitter power invested solely into the digital signal, and unlike WWFD in Maryland, this particular station makes the worst-case scenario for an analog-to-IBOC conversion. In various parts of my house I can either hear ony digi-noise (i.e. the HD detector is not even triggered), otherwise there may be an HD "lock" but no audio, or still elsewhere the digital audio kicks in (and out) only after an extended period of buffering.

This is barefoot ... adding just about any externally-coupled loop or ferrite antenna makes a world of difference as one might suspect.

Tune in in 6 months or so for the post-mortem ...
