The UTC amateur registration database is here.
HERE are a few mode-specific comments addressing where modes are located now and probably where they are best placed in the future
Curious about who is on the air making two-way QSO’s? Roger, VE7VV, is maintaining this list. If you complete QSO’s, be sure to let us know so he can add you to the active operator list.
There were a few storms in the Southwest into northern Mexico this morning but they did not contribute to much noise based on reports. Parts of New England experienced a few storms and on-going rain static, however. Oceania remains the big story as storms continue to impact Australia, New Zealand and much of the western Pacific and reports and activity are suffering accordingly.
Geomagnetic conditions are very quiet. The Bz is pointing to the South this morning, however, and protons have experienced elevated periods, including one period at 0911z where 74 protons/cc were observed. Solar wind velocities are averaging near 285 km/s. DST values are at or have exceeded the centerline, into positive territory.
Propagation was very good during this session but was also very erratic. QSB resulted in wild swings in signal levels and this morning I found a total loss of receive directivity for about 45 minutes which is often indicative of signals coming from directly above. Terrestrial noise levels were very low. Nights like this can be fun sometimes in spite of the fact that one often spends a bit of time waiting for an opening to cycle around again.
Reverse beacon network reports for the session follow:
North American PSKReporter results for the session follow (note that only North America is displayed today due to a band error from a station in the Northeast that was reporting Europeans from another band):
Laurence, KL7L, submitted this JT9 console capture showing stations he heard overnight:
Jim, W5EST, submitted the following JT9 captures received by his system in Little Rock, Arkansas:
Here is a brief sample of JT9 signals heard at KB5NJD over a 20-minute period during the evening:
The following stations provided reports of their two-way QSO’s as well as any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):
Eric, NO3M, completed first time JT9 QSO’s with Ernie, KC4SIT, and Bob, K9KFR. Eric indicated that he was hearing Bob at -24 dB S/N at 0222z.
Rick, W7RNB, reported JT9 QSO’s with VE7VV and W0YSE. He heard N6GN but indicated that he was unable to complete the QSO. On WSPR overnight he reported seven stations and he received reports from 35 unique stations. Rick’s unique report details can be viewed here.
Al, K2BLA, reported low QRN this morning. He completed JT9 QSO’s with ZF1EJ and KC4SIT. Al reported that Ernie was a “new one”. On WSPR, Al provided reports for fourteen stations and he received reports from 51 unique stations including best reports for K9FD (/KH6) at -7 dB S/N.
Ken, K5DNL, reported a JT9 QSO with W7IUV during the evening. Overnight using WSPR, Ken reported fifteen stations and he received reports from 65 unique stations including EA8BFK and seven Canadian stations. He shared two-way DX reports using WSPR with K9FD, VE7BDQ and ZF1EJ.
Larry, W7IUV, completed a JT9 QSO with Ken, K5DNL. He attempted a late QSO with KL7L but was not seeing Laurence at the time. On WSPR, Larry provided reception reports for VK4YB as W7IUV/W.
Ernie, KC4SIT, reported that JT9 QSO’s were completed with “Eric NO3M (-11, +4, 457 miles), Al K2BLA (-14, 4, 433 miles) and David AA1A (-21, -12, 786 miles).” He also completed a bonus FT8 QSO with “Eric NO3M (-17, -12, 457 miles).” Overnight using WSPR, Ernie received reports from 61 unique stations including two-way WSPR reports shared with K2BLA, AA1A, and N1DAY.
Roger, VK4YB, indicated that “QRN still high but much improved, allowing K9FD to be decoded. JT9 wkd ZL2BCG, hrd by VK4AQJ, KL7L. WSPR hrd 6, hrd by 17. Going to bed early.” Roger received WSPR reports from JA1NPK/2, KL7L, N1VF, VE6XH, VE7BDQ, W7IUV/W and W6SFH. He shared two-way reports with K9FD.
I (KB5NJD) briefly worked JT9 in the evening but the passband got really busy so I QSY’ed back to CW after about twenty minutes. I was glad I did as I caught a very loud W0RW CQing on 473 kHz. Paul peaked at a true RST 599 for about five minutes. He was RST 559 during our QSO (I received the same from him). Paul called me back about five minutes later (while at RST 599) as I was walking back into the ham shack and he was so loud I was hearing him in my head phones that were not even on my head. Paul was now experiencing precipitation static from snow and not hearing me very well but he was still banging in here to North Texas. I QRT’ed shortly after this second QSO. This morning at 0915z, the band was quiet but I had almost no directivity with my receive antennas and took a few minutes to ensure everything was working OK. It was so this was likely due to spotlight propagation. The band was really noisy during this time frame as well. Directivity improved after 45 minutes and was significantly better by 1040z when I worked K8TV on a brief peak. I was greedy and the bottom dropped out on my final frame of our QSO [Ken reported in a later email that he had switched to his 160-meter dipole to listen to me and forgot to switch back to the transmit antenna when he began transmitting again so the band may not have dropped out as I suggest.] I made this recording of Ken in the middle frame of our QSO:
I also received a report from Steve, KT5H, in Arkansas that indicated that I was ranging from RST 339 to RST 589 around 1000z. Reverse beacon network reports were also very plentiful. I suspect I had someone in the Pacific Northwest calling me which may have resulted in the 98 dB S/N report in VE6. The last time that happened, VE7VV was calling me right after my CQ and CW Skimmer was confused. Propagation was very unstable this morning but the band was definitely open. I QRT’ed around 1100z to get the day started.

Jim, ZL2BCG, received WSPR reports from KL7L, VE6XH, W7IUV/W. He shared two-way reports with K9FD.
Trans-Atlantic WSPR report details can be viewed here. The trans-Atlantic WSPR summary follows:
K5DNL -> EA8BFK
W3LPL -> EA8BFK
G3KEV -> AA1A
F5WK -> W1IR, VE3CIQ, AA1A
AA1A -> DG3LV, DH5RAE, DK6MG, DK7FC/P, DL/PA0EHG, DL4RAJ/2, EA1FBU, EA2HB, EA7HPM, EA8BFK, EB8ARZ/1, F1AFJ, F59706, F5WK, F6GEX, G0LUJ, G0LUJ/6, G0MJI, G4CPD, G4ZFQ, G8HUH, M0NKA, PA0O, PA0RDT, PA1SDB, PA7EY, PI4THT
Mike, WA3TTS, reported that he decoded fourteen WSPR stations overnight, including “…31 K9FD spots, best -20 @ 0858, min -33 @ 0516, 0530, 1002 utc. Also 41 ZF1EJ decodes, best -4 @ 0812 min -20 @ 0542, No PNW on wspr.”
Dave, N4DB, reported that he decoded WSPR from K9FD (/KH6) twice during this session for only the second time ever at his station.
Doug, K4LY, reported that using WSPR, he “…Listened on small amplified KAZ antenna I put up Saturday favoring south and had best ever SNR of +13 from K2BLA FL and best of season from ZF1EJ…At 5 AM switched to loop and had first decode of season from W0YSE.”
David, N1DAY, reported that he operated WSPR during this session, reporting thirteen stations and receiving reports from 58 unique stations. He spent some time making comparisons with KC4SIT who is located close and using similar equipment. David found that his reports were generally better on the path to the West, which happens to be unobstructed by mountains.
Roger, G3XBM, posted the following testimonial and encouragement on the RSGB-LF reflector for operators who don’t think they can put a working system on 630-meters:
“If anyone needs convincing that getting on 630m is easier than you think please take heart from my results.
In the last 2 weeks I have received 31 unique WSPR spots from as far away as Norway. Measured ERP is around 10mW. The antenna and ground? The coax to my 2m big-wheel which is about 0.5m above ground for about half its length. At its highest it is about 4m over ground. The total coax run is less than 10m. The only grounds are a mains earth and one earth rod about 10m from the shack. My ATU is a multi-tapped ferrite rod on the desk. My transverter is my simple design in “LF Today”.
Although I tried calling CQ on 630m FT8 earlier this evening, sadly I got no response. Another evening I’ll be more successful. Earlier I saw a weak FT8 trace.
630m is for all! BTW, my noise floor is S7.
Not the DX of the “big boys”, but fun. Ultimately this is why we are in our hobby.”
Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, completed two-way JT9 QSO’s with K2BLA and AA1A this morning. Overnight WSPR resulted in reports for ten stations. Eden received WSPR reports from forty unique stations. He shared two-way WSPR reports with K9FD.
Laurence, KL7L, attempted a JT9 QSO with W7IUV but at the time the band conditions were not so good. In his JT9 receive window this morning were W0YSE, ZL2BCG and VK4YB. He added that “VK at 1120, Zl at 1123z – but just a couple of decodes and Nothing from East of the Rockies/Cascades.” Laurence was mostly receive-only overnight using WSPR while he awaits improved band conditions. He provided WSPR reports for eight stations including VK4YB and ZL2BCG. He shared a few two-way reports with K9FD while transmitting briefly. Select DX report details can be viewed here.
Merv, K9FD, provided WSPR reports for eighteen stations including VK3HP. He shared two-way WSPR reports with KL7L, VK4YB, ZF1EJ, ZL2AFP and ZL2BCG. Merv received WSPR reports from 52 unique stations including JA1NQI, JA1PKG/2, JA3TVF, JE1JDL, JH3XCU and VK2XGJ. Select DX report details can be viewed here.
Jim, W5EST, presents ,”Case Study: A 630m/2200m Slow-Voice Phone Mode“:
“In yesterday’s blog, I excerpted some reports on 630m SSB QSO distances out around 1000-1700 km by VK amateur stations this last June-August. At amateur 5w EIRP, how far can 630m SSB or some voice mode reach in N. America this winter?
Distance is one thing, bandwidth is another. A 630m/2200m voice mode of whatever phone mode type is challenged not only to deliver intelligible SNR at hundreds of kilometers but also to conserve spectrum–while being convenient to use!
On 630m the top 3 KHz, 476-479 KHz, is suggested for SSB, SSTV and other “wide band” modes–especially at night. http://njdtechnologies.net/what-happens-where-on-630-meters-a-few-more-comments-about-where-to-place-your-signal-depending-on-mode/ On 2200m, the entire 135.7-137.8 KHz spans just one single SSB 2.1 KHz bandwidth.
A few weeks ago another MF/LF voice mode topic reappeared on an RSGB reflector: http://njdtechnologies.net/081217/ . It’s a slow voice mode method that DK8KW and DF6NM tried out on 2200m in the year 2000.
That slow voice mode slowed down a human speech frequency band 300Hz-3kHz by a factor of 10 division ratio to a frequency band 30-300Hz. By upconverting the slowed audio to 800Hz +/- 150Hz, one could send via a SSB 630m TX and receive it with 300 Hz CW filter bandwidth. The reception process reversed the steps to recover speech. http://dl0rcp.bplaced.net/index.php/webapps-2/qrssb (click on link at Anleitung:Datei als PDF for 2nd page, 1st paragraph. The site offers a zip file.
Here’s the sound of that slow voice mode: http://www.qru.de/slowvoice.html (12Kb link in 1st paragraph plays unintelligible sounds, possibly from a transmission).
Next, scroll down 1/3 and play “MP3-Sound Samples of this QSO” by clicking on links in the box for DK8KW transmitting and DF6NM transmitting. (mp3 files of DK8KW-DF6NM intelligible decoded voice in 250 Hz b.w. on 2200m 12/31/2000). Scroll halfway for processing description.
For a block diagram of that slow voice system, see:
http://dl0rcp.bplaced.net/index.php/webapps-2/qrssb (click on link at Anleitung:

As to permitted modes and operations, use your best informed judgment to stay compliant with all governing radio rules in your country. In another blog post I’ll explain why I think that such slow voice SSB is permitted in USA as a phone mode J,(1,2,3 or X), E. See what you think.
If you try this slow voice mode of the DK8KW-DF6NM experiment, occasional tail-end CW could send your call sign and a CW phrase like“Voice slowed 10x upconv 800 Hz.” Since operation on 630m or 2200m is a new experience for many of us, such a CW trailer can inform and invite. The number of concurrent voice QSOs that a band could support would be increased by a factor equal to the division ratio used.
A slow-voice QSO of the DK8KW-DF6NM experiment would take longer to complete than a regular SSB QSO. Meanwhile, it would conserve spectrum and potentially reach farther distances than same-power SSB.
Variants of that slow-voice mode would amount to other instances of: 1) Division ratio, 2) upconversion Hertz, 3) USB or LSB. Notice that slow-voice mode merely alters the voice waveform in rate and audio frequency. It does not attempt compression by speech coding. https://en.wikipedia.org/wiki/Speech_coding
