New Years’ Eve Sporadic E-skip DX

New Years Eve here in Melbourne produced a nice opening of FM signals from Queensland. It was a very warm day, so sitting inside a stifling little room wasn’t exactly my definition of fun, but some of the results proved worth it. Despite the fact that I had to pack for a flight to Queensland that night, I spent most of my afternoon by the radio listening and recording these signals.

90.5 4RBL “Rebel FM” Beaudesert QLD

Despite Queensland coming in most summers here in Melbourne, this particular station seems to be a touch rarer. First time reception for me, and as a fan of the music they play on Rebel, I was particularly glad to hear a bit of it.

90.5 2WEB/t Lightning Ridge NSW

An interesting catch, given that this is a low-powered translator of the AM station from Bourke in north-west New South Wales. Received just after the aforementioned Rebel FM reception. Particularly stoked to grab this one as it’s listed in the ACMA book as only putting out 25 watts. A fairly clear ID comes in at the end of the recording.

91.1 4MCY “Hot FM” Nambour QLD

This clip shows what a real mess this frequency was that day. In addition to the permanent ABC radio station from Bendigo (which can’t even be heard here), two DX signals were fighting it out. The clearest one with the American voices was Hot FM from the Sunshine Coast in Queensland, with the other ad heard suspected to be Rebel FM from Tara, also in Queensland.

91.3 2NOW/t “Now FM” Lightning Ridge NSW

Nice end to a song with a good promo heard here identifying the station.

92.5 4GLD “Gold FM” Gold Coast QLD

As a high-powered commercial station on the Gold Coast, this isn’t a hugely rare catch, but still interesting. Caught the start of the news with some good clear IDs. The signal strength was something to note as well.

95.1 4RGK “Sea FM” Gladstone QLD

Sadly no clear ID was nabbed here, but I included it as a) I’m 99% sure it was this station (other Rockhampton/Gladstone stations were in at the time), and b) it made a fair effort to get over the permanent local NewsRadio signal from Traralgon that normally sits at 2-3 bars signal strength on the Sony receiver I use. Another first time catch for me.

104.5 4MMM Brisbane QLD

Got a good chunk of the traffic, news and the intro to the first song. All the Brisbane stations were in very well at this stage, as the photo below from Triple M’s sister station B105 will show.

The Sony unit I use is notoriously difficult to use for capturing RDS signals. Even on the semi-local stations it tends to struggle to decode the station name and information. So I was amazed when after a few seconds sitting on 105.3 the unit managed to grab the station name and proudly display it, along with 3 bars of signal. I couldn’t get Triple M or Nova to display their data, but B105 showing up was still pretty impressive.

107.9 4ROK “Hot FM” Rockhampton QLD

One from the top of the dial, literally. I nabbed Brisbane JJJ on 107.7 before this, but getting Rocky on 107.9 just shows how good an opening this was, nothing on the FM dial was missed. The faint signal in the background is ABC local radio from Ballarat that is only a faint permanent signal where I am due to my shielding to the west.

Stupidly, I was too busy mucking around recording to do a proper log, but I can basically confirm that everything between the NSW border and Rockhampton was coming in at at least one point that afternoon. The signals were at times so strong and consistent that I had the portable boom box in the bathroom (the one that can’t even pick up the Geelong stations from here in Clayton) locked on 99.3 4JJJ from the Wide Bay/Bundaberg area, and when I say locked on, I mean barely fading at all for a good 20 minutes.

So funnily enough, I was listening to the Queensland stations all afternoon, and by 7PM that night, I was up there myself listening to them again as local stations. Also worth noting that while up there in Coolangatta on the southern Gold Coast, I received a good block of 91.5 Radio Nouveau Caledonie, my first ever non-English speaking nation reception, and only my second international FM reception. I’m led to believe New Caledonia frequently appears in Coolangatta, and I was aided by being in a 14th floor apartment with views directly to the east, but for my little Tecsun unit to nab that made me very happy that day. It even impressed a few of the local folk too.


MS/AS signals on 96.1

After the shutdown of Melbourne community station Lion FM, I’ve already had a handful of interesting signals on our new blank frequency. Few of them I can identify clearly, but I’ll share them with you anyway

MS ping 1

A fairly clear but short MS ping, this one kinda sounds urban. My guess is “The Edge 96ONE” from Katoomba NSW, or JJJ from Lismore NSW. Can’t really be sure though.

MS ping 2

Even shorter than the first, and also affected by the fact that it had to overcome the blank signal from the local 96.1 that was still broadcasting at the time. My guesses are the same, though this pop piece means Star FM Mt Gambier may also not be out of the question.

AS signal

This one’s a little more developed as it’s not an MS ping – it sounds more likely aircraft scatter (ironic given the lack of aircraft flying in this part of the world at the moment). There are two songs, both by U2 as part of a doubleshot. At about 1:20, there’s an ID which while muffled sounds like it says “suburban doubleshot”. My guesses are Star FM Mt Gambier or perhaps even more likely, 7THE (Radio Hobart) from Tassie.

Either way, some interesting results have come in just hours after DXers got the use of this frequency back here in Melbourne.

Clayton Bandscan, with a twist

I’ve decided, as promised, to do a bandscan now that I’ve put the antenna up. But I’ve done it with a twist – instead of it being a tedious list of stations, I’ve recorded my dial surfing and put it to a video, captioning with which station I’m on. I figured why not let everyone hear what I can. For the record, the details are as follows. The radio is my Sony XDR-F1 HD radio, wired into the sound card on my computer. The antenna is an Academy TV 3-element FM antenna, aiming North East, erected via a fascia-mounted “hockey stick” located on the eastern side of my house in Clayton. The date was May 19 2011, the time approximately 12:20-12:30 AM (yes I know, I’m a night owl 😛 )

I’ve uploaded it to Youtube, so everyone can share the love:

Hope it’s of some interest to you. Enjoy!

Tropo and E-skip DX, 20 January 2011

I was down in Geelong and unfortunately feeling unwell on Thursday, so I didn’t make it in to work. That proved to be handy from a DX point of view, as I got to enjoy one of the strongest tropo openings to Launceston I’ve seen in a long while. Below is a log of the stations I received (bear in mind this was with the Sony tuner hooked up to the household TV antenna which was pointing the wrong way for Launceston).

90.1 7EXX “Chilli” Launceston TAS – 1 bar (click to listen to a brief recording of this one transmitting a test loop)

90.9 7JJJ Launceston TAS – 3 bars

91.7 7NT Launceston TAS – 3 bars

92.5 7PB Launceston TAS – 3 bars

92.9 7JJJ Hobart TAS – 1 bar (first time catch)

93.3 7ABCFM Launceston TAS – 3 bars

94.1 7ABCRN Launceston TAS – 2 bars [1]

106.9 7RPH Launceston TAS – 1 bar (first time catch)

[1]: Received over splatter from adjacent local 93.9 3BAY Geelong and co-channeled semi-local 3WBC Box Hill

The Hobart reception was a first for me. Others in Melbourne have received Hobart FM and even TV in the past, but it generally takes a very strong opening to Tassie to get it. I was a bit surprised to not have received any more of the low-powered Northern Tasmania stations, but it didn’t worry me. I should also mention that local analogue TV GTV9 Melbourne was suffering from co-channel interference from TNT9 Launceston, despite our antenna aimed to block out Tassie and specifically receive Melbourne.

Later in the evening, thanks to a tip-off from a friend and fellow DXer in Brisbane, I noted some sporadic-E FM reception from Queensland. The opening only really lasted for about 10 minutes after I first got to listening, but I noted most of Brisbane’s high-powered FM stations.

93.3 4SBSFM Brisbane QLD [2]

97.3 4BFM “973 FM” Brisbane QLD [3]

102.1 4ZZZ Brisbane QLD

104.5 4MMM Brisbane QLD

105.3 4BBB “B105” Brisbane QLD

106.1 4ABCFM Brisbane QLD

106.9 4BNE “Nova” Brisbane QLD

107.7 4JJJ Brisbane QLD

[2] 4SBSFM was fighting with 7ABCFM Launceston for the frequency. When 4SBSFM faded, 7ABCFM was heard.

[3] Very weak, probably due to adjacent channel splatter from 97.4 3WRB Hoppers Crossing

93.3, 106.1 and 107.7 were much stronger than the rest, probably due to them being much higher powered transmitters. Still, it’s the first definite E-skip reception I’ve had this season. I suspected some reception a few weeks back, but couldn’t confirm it. It would have been really disappointing had this not occurred, and the season finished before I had at least heard something.

For the record, the E-skip season, especially for FM reception, generally winds up towards the end of January or start of February.

Bandscan in Geelong: 18/19 October 2010

I was at the parents’ place in Geelong, and took the Sony XDR-F1HD radio I own with me to have play with. Just hooking it up to the TV antenna socket seemed to work well enough for a number of purposes. The antenna is a multi-band antenna designed to cover all of VHF Bands I, II and III, as well as UHF Band IV, so it would work for FM radio. It’s permanently aimed north-east for reception of Melbourne TV signals, broadcast from Mt Dandenong, east of Melbourne.

Worth noting too is that no tropospheric ducting effects were observed during this log. Conditions were as good as completely dead, except for the troposcatter, meaning this is a list of stations permanently receivable at this location.

The stations received were as follows:

87.6 Unknown LPON playing a loop tape, 1-2 bars signal on the Sony meter

107.1 3JJJ Ballarat VIC, 1-2 bars

107.5 3JJJ Melbourne VIC, 3 bars

107.9 3CRR “ABC Western Victoria” Ballarat VIC, 1-2 bars

[1] Local services that caused significant spill on adjacent frequencies +- 0.2 MHz either side of designated frequency. 89.3, 93.9, 94.7 and 95.5 were particularly bad. 96.3 and 99.5 were negligible.

[2] 89.3 HPON produces several images in lower regions of the dial, noticeably on 88.7 and more limited causing IF to 89.9, especially near the TX site

[3] Troposcatter/Aircraft scatter reception that varied in signal strength over time. Given signal strength is peak strength received

[4] Received underneath splatter from adjacent local channels

[5] 3ABCRR was fading in and out via troposcatter, and was dominant when in. 3SER was heard when 3ABCRR faded. Both clearly identified

[6] Both 8SAT and 3CCS could be heard, but neither seemed dominant. Hard to identify either, but reception of both is common in the general area

Swan Hill FM via Aircraft Scatter: 8 October 2010

This is the first of the logs I’ll be posting here, though in this case it’s only one station. I actually set the computer to record the radio and filtered through the sound file to pick up this signal.

102.1 3MIL “ABC Swan Hill” Swan Hill VIC

(Click on the station name to listen to the recording)

This was received here in Melbourne via a propagation method known as Aircraft Scatter (AS in shorthand). As the name implies, this means that the signal has been reflected off the bottom of aircraft flying overhead, allowing for long distance reception. The recording only goes for about 30 seconds, as once the plane has flown out of the optimal zone for reflecting the signal here, it disappears completely. Often these go missed, but I happened to be recording at the time, so I could pick it out by analysing the recording in a program like Audacity.

Swan Hill is not normally receivable here in Melbourne, it’s just that bit too far away. However, with the assistance of aircraft or the atmosphere, the signals do come in, although in this case only briefly.
