2011 CQ Magazine World Wide WPX Contest, SSB

Logged a lot of stations heard in another amateur radio contest, the 2011 CQ Magazine World Wide WPX contest, SSB. Date: Sun. March 27, 2011. Time: 11:50 - 13:00 UTC and 17:50 - 22:55 UTC. Bands: 20 and 15 metres (14 and 21 MHz).

Stations heard from Europe, North Africa, and the Americas: Anguilla, Argentina, Aruba, Belgium, Belize, Bermuda, Canada, Canary Islands (Spain), Colombia, Croatia, Denmark, Dominican Republic, England, Finland, Germany, Ireland, Italy, Martinique, Morocco, Poland, Portugal, Russia, Serbia, Scotland, Spain, Trinidad & Tobago, United States, Wales.

WKVQ 1540 kHz Eatonton, GA

Very early this morning the nice folks at WKVQ 1540 in Eatonton, Georgia, put on a special DX test broadcast to give DXers a chance to log them. I did not expect to hear this station because Georgia is a long way from Toronto, and because we have a 50 kW local station (CHIN) on 1540 here. WKVQ is 10 kW day, 1.6 at night. I don't know which power they used for the test but even a 10 kW station is a tough catch on a crowded frequency at that distance. Nevertheless, I knew that the station would be broadcasting Morse code IDs and that Morse code has a real ability to punch through the noise. I figured that if CHIN had a program of talk, not music, that there might be the occasional gap through which WKVQ might creep. I've logged other stations this way, by hearing IDs during brief silent pauses on the dominant station. So I set things up to record 1540 overnight so I could review the recording later.

The DX test was scheduled to run from 06:00 to 06:30 and from 07:00 to 08:00 UTC. That's 1:00 to 1:30 and 2:00 to 3:00 a.m. local time. CHIN was playing music, but there was an announcer between songs. At 06:29 I thought I heard a Morse code ID underneath CHIN during a momentary pause in the announcer's speech. Very, very faint. I had to listen to the recording over and over, fiddling with the equalizer settings in Winamp to boost certain audio frequencies and to suppress others. Eventually I was able to improve it enough to verify that I was hearing "WKV?" with the final letter being four elements long - it was partly wiped out by the announcer on CHIN. Since "Q" is a four element character in Morse code, and since no AM station is going to broadcast its ID in Morse code except in a DX test, and since there are no other stations on this frequency whose callsign starts with WKV, this was enough to convince me it was WKVQ. Cool!

This is station number 965 in my overall mediumwave log, and number 386 in the Toronto log.

2011 ARRL International DX Contest, SSB

More DXing on the amateur bands - stations heard while I was making contacts in the 2011 ARRL International DX Contest, SSB. Date: Sunday March 6, 2011, Time: 15:10 - 20:30 UTC, Bands: 15 and 10 metres (21 and 28 MHz). Good conditions, and 10 metres was open to the south.

NRV 8422 KHz

Caught a distant one today, Friday, March 4, 2011 at 13:30-13:43 UTC. On 8422 kHz I heard NRV, a U.S. Coast Guard station located on the island of Guam in the western Pacific Ocean. It was broadcasting a SITOR channel marker with Morse code IDs. I didn't have anything set up to decode the SITOR signal but the Morse code ID was clear. This is my first logging of this station, and of any station from Guam.

2011 ARRL International DX Contest, CW

This weekend (Feb 19 & 20, 2011) has one of the big amateur radio contests of the year, the ARRL International DX Contest, CW. I was on the air making contacts in this contest, and during this time I also kept a log of all the stations I heard, worked or not. I've said this before but I'll repeat it again: if SWLs are looking for a new aspect to the hobby of shortwave radio, they should check out the amateur bands, especially during a major contest. There are a lot of DX targets available on the amateur bands from places that have few, or no, shortwave broadcast stations. Here are some of the highlights of what I heard:

Two Amateur Radio Contests

On the air this weekend making contacts in two amateur radio contests. Feb 12 & 13: CQ WPX RTTY contest. Feb 13: SKCC Weekend Sprintathon. Logged a lot of stations but nothing unusual.

WCXN 1170 kHz Claremont, NC

I logged a new mediumwave station today, Feb. 12, 2011: WCXN, 1170 kHz, in Claremont, NC. I heard a Spanish language station on 1170 under WWVA, so I left the radio on overnight, using the Sony MP3 recorder to record it. The station was present all night, making the time of this logging 0340 to 1000 UTC.

The station was usually under WWVA, but sometimes dominated the frequency. Mexican music format with several “La que buena“ IDs. No callsign heard - not sure the station ever gave one. But “La que buena“ is WCXN’s slogan. Also while WCXN is a daytime only station, it has been reported widely on the DX reflectors as frequently staying on all night. Since there are no other plausible candidates, I concluded this must be WCXN.

There was also a second Spanish station heard with talk under WXCN a few times. But it was very weak with no identifying material heard.

This is the 385th station in my Toronto mediumwave log, and the 964th in the overall log.

Two More Repeater Loggings

The only recent loggings to report are two new amateur repeaters heard. These are just local stations, but logging these things is still a new activity for me, since I've spent so little time exploring the VHF amateur bands.

• Mon. January 24, 2011 at 0015 UTC: VA3GTU, Toronto, ON, on 145.13 MHz with Morse code ID.
• Sat. January 29, 2011 at 1345 to 1445 UTC: VE3RTC, Scarborough, ON, on 146.745 MHz with Morse code ID. There were two amateurs having a chat here but it was in Chinese and I didn't catch their callsigns.

Amateurs on 2 Metres

Today's loggings come courtesy of the 2 metre amateur radio band:

• 1615-1630 UTC, 145.13 MHz. Heard several stations checking into the morning ARES net. ARES is the Amateur Radio Emergency Service. This net is run by the Toronto ARES Group. I think they meet here every morning at this time. First time I've heard them, mostly because I seldom visit the VHF amateur bands.
• 1645 UTC. Heard the Morse code ID (in FM mode) of VE3RTR on 145.15 MHz. This is a repeater that covers a large swath of the north shore of Lake Ontario. It is located near Baltimore, Ontario. It is operated by the Heritage Amateur Radio Club.

BARTG RTTY Contest

Today's radio activity: I was on the air making a few contacts in the BARTG RTTY contest and I kept a log of the stations I heard. Nothing special. Despite this being a British contest, the only stations I heard were in the U.S. and Canada, only 14 stations. Conditions didn't seem very good today. Listened between 1832 and 1923 UTC, and again from 2146 to 2219 UTC. 20 metre band, around 14.1 MHz.

CJY241 - 152.87 MHz

Continuing with the casual exploration of what can be heard on VHF, I caught an interesting one today. This morning, Fri. Jan 21, 2011 at 1320 to 1335 UTC (8:20-8:35 local time), I found a frequency that CBC Radio reporters use to talk to the studio. At least that's what I heard. Specifically, I heard a silent carrier on the frequency from 1320 to around 1330. Then one half of a conversation was heard. I already thought this was a CBC feed so I turned on an FM radio to CBC Radio One at 99.1, and heard the same conversation there. The CBC was broadcasting the news and the anchorman was talking to a CBC reporter at some location. What I heard on 152.87 was that reporter's half of the conversation. According to RadioReference.com the callsign of this CBC media feed station is CJY241.

I actually first heard this station on Jan 14 (that's why I was sitting on the frequency today) but on the 14th I didn't hear enough material to ID it.

There's such an incredible variety of signals on the radio bands and I'm always surprised when I discover yet another way in which radio is used.

Miscellaneous Loggings

Heard / seen on the radio today:

• At 1544 UTC I heard VE3NUS on 224.3 MHz with a strong signal. VE3NUS is an amateur radio repeater in Unionville, Ontario (just north of Toronto). No traffic heard; just the repeater's automatic Morse code ID. This is the first amateur station I've ever heard on the 222 MHZ (1.25 cm) band. (I don't spend much time on the VHF and UHF amateur bands).
• Saw two amateur stations operating in SSTV on 14230 kHz. At 1941 UTC caught K05Z from Krugerville, TX calling CQ SSTV with a weak signal. A few minutes later I caught another image from him, now working AB0HB. Then at 2040 UTC I got WA4PEQ working some stations, including VE3IYA. Decoded using MMSSTV.
• Back on VHF, tuning around and caught one of the dispatch frequencies of one of Toronto's big taxi companies, Beck Taxi, on 150.28 MHz. Excellent signal. Issuing instructions to cars. This was at 2240 UTC. (I stumbled across this one while setting up computer control of one of my radios).
• At 2246 heard an unidentified amateur radio net in progress on 146.810 MHz in the 2 metre band.

Amateur Loggings

DXing the amateur bands today. What I logged:

• SSTV: Received KC4RP, McDonough GA, on 14230 kHz at 1538 UTC calling CQ. Only received a single image and no sign of an answer.
• PSK31: Logged KT4WI in Ormond Beach FL, on 21072 kHz at 1653 UTC. In contact with F6EQZ, who was not audible here.
• ARRL RTTY Roundup contest: Logged a lot of RTTY stations between 1700 and 2215 UTC on the 15 and 20 metre bands. Most were in the U.S. and Canada, but I did log a few from elsewhere: PZ5RA in Paramaribo, Suriname (15 metres); P49X in Aruba (15 and 20 metres), HI3TEJ in Puerto Plata, Dominican Republic (15 metres), and XE2K in Mexicali, Mexico (15 metres).

SSTV on 20 Metres

One of the many transmission modes that radio amateurs can use on the HF bands is slow-scan television (SSTV). SSTV lets one transmit pictures using a narrow bandwidth signal, one narrow enough to fit in the 3 kHz legal bandwidth limits on the HF bands. The tradeoff is that low bandwidth means slow transmission and low resolution. In fact, it can typically take between 30 and 120 seconds to send a single frame. There is also no audio. So SSTV doesn't allow for the transmission of video. Instead, it is more like a slow slideshow, with pictures in SSTV mixed with talk between them in standard SSB.

Anyone with a shortwave receiver that supports SSB and a computer with a soundcard can decode SSTV signals. I use free software called MMSSTV for this. MMSSTV also generates SSTV signals that can be sent to a radio transmitter, of interest if you're a radio amateur that wants to try out this mode.

Radio amateurs using SSTV tend to stick close to a small range of frequencies so they can find each other. On the 20 metre band they're usually found around 14230-14240 kHz.

Today I had MMSSTV running, monitoring 14230 kHz to see what would pop up. I caught two stations operating in SSTV:

• WB5UXC, Pearlington MS at 2200-2220 UTC with a fair signal. He was in contact with KA0UNB (who wasn't visible to me) and with an N9 station. At 2219 he was calling CQ using a special CQ image.
• XE1RK, Mexico City (D.F.), Mexico at 2221-2230 with a good signal. This station answered WB5UXC's CQ call and they swapped pictures and talked in SSB. Fairly clear picture.

It may just be a slow slideshow but I think it's great that amateurs can transmit a type of television signal on shortwave.

Note that SSTV is different from ATV (Amateur television), where amateurs transmit standard broadcast quality television signals. ATV allows for full video with audio, but is restricted to the UHF bands because of the wide bandwidth needed.

Loggings on Highway 7

I drove back to Toronto today from Ottawa and DXed the AM band while I drove. Car DXing is simple enough - leave the car radio on some frequency while one drives. If something worth logging pops up, pull over, then note down the details. The pulling over and stopping isn't necessary if one uses a voice recorder to make notes, but I don't.

Conditions on the AM band were great today. Occasionally, around the time of the winter solstice, some amount of skywave propagation can remain in effect all day. Normally there is no skywave propagation on mediumwave frequencies during daylight hours because of the ionizing effect of the sun on the D layer of the ionosphere. This layer absorbs signals at these frequencies, preventing them from propagating further. At night, the D layer disippates, which allows signals at mediumwave frequencies to pass through it to the higher F layer, which reflects them back to earth. This is the reason for long distance propagation on the AM band at night. However, around the time of the winter solstice the days are the shortest of the year, and the sun is at the lowest elevation in the sky. So the D layer does not get as strongly ionized and skywave propagation on mediumwave doesn't entirely disappear during the daylight hours. I would expect this phenomenon would be stronger, more frequent, and occur over a longer period of time at more northerly latitudes. Here in southern Ontario I've only ever seen it happen within a couple of weeks of the winter solstice. And it was happening today.

I logged the following stations. I heard more stations than this, but as I was driving I didn't think it was worth stopping to log stations I knew I'd heard before. Four of them turned out to be new catches, which is a fantastic haul. Combined with the three new ones I caught in Ottawa earlier, I got seven new stations on mediumwave today. I can't remember the last time I got so many new ones. This brings the overall mediumwave log count to 963.
