Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Excellent session with very quiet terrestrial conditions and just enough spark with the geomagnetic field to result in big transcontinental, trans-Atlantic and trans-Pacific openings on a variety of modes including KL7L <-> W0YSE, VE7VV, W7IUV on JT9 and KB5NJD <-> VE7SL, VE7CNF on CW; KC4SIT -> EA8BFK first time WSPR reports; W5EST presents: ”Dive Deeper into 630m Voice Modes”

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for November 2, 2016 can be viewed here.

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.

Noise was very low in North America although a few areas of the Northeast experienced  heavy rains as well as a few evening storms in the Midwest.  The situation in Oceania appears to be improving some but a number of big storms remain active.  Storms in Japan that were creating noise in the previous session are now located over open water.

Geomagnetic conditions reached elevated-quiet levels during this session which may have provided a bit of a spark allowing amazingly strong and stable propagation.  The Bz was pointing to the North for much of the night but has since turned to the South this morning and solar wind velocities are averaging near 365 km/s.  DST values from both measurements were making a strong push into positive territory  but decreased briefly only to return to the center line and back into positive territory.




Propagation was amazing, perhaps the best of the season so far as it was coupled with very low terrestrial noise.  Signals were strong and would jump out of the noise.  This morning the path to the West was very open.  I normally don’t spend much time listening West in the morning because most operators are asleep but there were a lot of active operators this morning and the band was packed with activity.

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!):

Neil, W0YSE, reported that he heard K7SF calling CQ on 474 kHz CW during the evening but his calls were not picked up by RBN.  He also listened for W0RW, who called CQ for quite a while on 473 kHz but Neil had no copy at the time. Neil indicated that he received two RBN reports (presented earlier in this report).   On JT9, Neil completed the following QSO’s with Canadian stations:

This morning Neil reported some excitement after completing a JT9 QSO with KL7L.  Neil explains:

“I just completed a JT9 QSO with Laurence, KL7L. I think Rod, VE7VV might have done it just before me. We were both calling off Laurence’s QRG so as not to QRM anyone else trying to call him.  I was about 40 hz below Laurence, and Rod was about 40 hz above him. Here is part of my left-hand screen in WSJT-X.”

Eric, NO3M, is working towards a QSO with European stations and has been in contact with a few operators to attempt to arrange a sked.  During this session Eric was working with SV8CS to try to complete a JT9 QSO while he was also seeing G8HUH and F5WK, the latter of which was at CW levels at times on WSPR.  Unfortunately none of these other stations made it to JT9 during the peak of this session.  Hopefully they can get a plan worked out in the coming days and break the pattern of only WSPR activity on trans-Atlantic paths.  Eric was strong on CW ten minutes before my local sunset as this recording suggests:


Eric also activated W8CDX, a call sign for which he is the trustee,  completing a number of QSO’s on CW, including one with me at very strong levels resulting from extremely stable and quiet band conditions.  Eric also completed a CW QSO’s with K1RGO and attempted one with K9SLQ, who disappeared into the QSB during a QSO attempt.  This morning Eric received JT9 from VK4YB twice at sunrise but he was not heard in Australia today due to sunrise in Pennsylvania.

Steve, VE7SL, completed a two-way JT9 QSO with K9SLQ and a very nice early morning CW QSO with me (KB5NJD) at uncharacteristically strong levels.  I have a recording posted later in this report.

Paul, W0RW, completed evening CW QSO’s with KB5NJD and K9SLQ and he received an email report from Nick, WA5DBU, located in Arkansas.  Paul indicated that Nick was listening on the 160-meter dipole and was recently approved.

Ken, K5DNL, reported that the “The band started out really hot then tapered off a bit.”  He completed JT9 QSO’s with  ZF1EJ, AA1A, VE7SL, and KC4SIT.  Ken also indicated that he heard VE7CNF calling KL7L this morning.  Overnight on WSPR, he provided reports for twenty unique stations including VK4YB which Ken indicates may be a record for his station.  Ken also received reports from 77 unique stations including EA8BFK, K9FD, ZF1EJ and eight Canadian stations.

Ernie, KC4SIT, reported that his WSPR signal reached across the Atlantic for the first time as he received two reports from EA8BFK.  He also indicates that he received WSPR reports from 71 unique stations including fifteen stations that exceeded  3000 km distance from his station.  Ernie was also active on JT9 this morning, completing a JT9 QSO with K5DNL (-26, -10, 850 miles).  Ernie is working through some setup issues with his new rig and transverter and I expect we will see many more QSO’s from him shortly.

Larry, W7IUV, completed a JT9 QSO with Laurence, KL7L, noting that he didn’t expect to get this one done so quickly.  Larry continued to report Laurence at -24 dB S/N fifteen minutes before sunrise in Washington state.  On WSPR overnight and designated as W7IUV/W, Larry reported VK4YB, K9FD and KL7L.

This was a fun session at KB5NJD.  The band was very quiet and stable, allowing a nice CW QSO with “Basil”, W8CDX.  I also briefly heard Sal, K1RGO, but not at strong enough levels or consistently for a QSO.  That’s a good sign because its a very long way to New England, even on a good night.  I was headed to bed and heard Paul, W0RW, calling CQ on 473 kHz CW so I gave him a quick call where we both exchanged RST 559 with one another.  I was tired or I might have stayed up later for some of the early West coast action.

This morning I was on the air again by 0915z and received some reasonable reports fairly early from the reverse beacon network.  Steve, KT5H, reported me at RST 589 in QSB at 0955z, 0956z and 0957z with reports continuing as I made intermittent calls through the morning.  Toby, VE7CNF, inquired in the ON4KST chat about what I was doing and so we made some calls on 473.5 kHz, which was more clear than my usual 474.5 kHz.  Signals were in the noise at 1015z so we opted to try again at 1045z and that was the right decision as Toby and I completed a very nice RST 559 QSO, both direction.  Toby’s signal continued to build even after we QRT’ed but here is a partial recording from our QSO (note that this starts as I am returning to Toby):

Moments later I was calling CQ again on 474.5 kHz and Steve, VE7SL, threw in his call sign as armchair copy levels so we completed a very nice RST 579 QSO, both directions.  Steve noted that there was no QSB whatsoever, which I was also observing but when I returned to him I was trying to say that the band was “silky smooth” and made a mess of it, as can be heard below.  It was too early and more coffee was necessary.  Here is a partial recording from the VE7SL QSO:


After this QSO, I got really brave since the band was in really good shape and asked Roger, VK4YB, to listen for me, which he did, and as he indicates below in his report, he hears CW that he could not identify.  Maybe it was me, maybe it was not but either way, it was a very encouraging morning with lots of activity on a variety of modes.  I look forward to what tomorrow morning brings.

Hideo, JH3XCU, submitted this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, experienced a very promising session.  He indicated that:

“Some heavy static crashes were coming from a storm system about 1500 km out in the Tasman sea. Between the crashes the band was very quiet. When I first tuned to 474.5, I heard a weak CW signal for just a few seconds but was not able to copy any letters. That may have been John, KB5NJD, who had just asked me to have a listen on a hunch that the band was in good shape. There was a fairly strong carrier about 100Hz above, but it was not much of a problem. I was using a very narrow filter. That carrier is usually present, which is why I use 474.3, when I call CQ.

The other excitement of the evening was getting two JT9 decodes from Eric, NO3M, and seeing his first trace on the waterfall at 11:47. I have seen traces weaker than that decode, but my guess is the static crashes just took out enough data to miss out on this occasion. Still, it is very encouraging.  We are really pushing the boundaries of what this band can do.”

On WSPR, Roger received reports from CF7MM, K5DNL, KJ6MKI, KR6O, VE6JY, VE6XH, VE7BDQ, W6SFH and W7IUV/W.  He shared two-way WSPR reports with K9FD and KL7L.

Rudy, N6LF, received WSPR reports from JA1PKG/2.

Al, K2BLA, provided reports for  eighteen WSPR stations and Al added that he had”…no new ones last nite or this AM. WSPR: HRD BY 63, a new record for me incl PA0RDT 2 ways with G8HUH (I know easy for you guys up north but not so much for down south) and K9FD. ”  Al also received reports from PA0RDT and he provided reports for F5WK.

Dave, N4DB, reported that he decoded seventeen WSPR stations overnight including N6LF at a distance of 3736Km which was a new station for Dave.

Eden, ZF1EJ, completed a JT9 QSO with K5DNL and reported a number of other stations but I don’t believe that additional QSO’s were completed during this session.  Overnight with WSPR Eden reported twelve stations and he received reports from 51 unique stations.

ZF1EJ session WSPR activity


Laurence, KL7L, indicated that there were some overnight storms that cleared by early morning, allowing him to complete JT9 QSO’s with VE7VV, W0YSE and W7IUV.  He also indicated that N6LF’s WSPR CW ID was RST 559.  In between the action, Laurence provided WSPR reports for seven stations and he received reports from eleven unique stations. He shared two-way reports with K9FD, KR6LA, N6GN, VE7BDQ and VK4YB.  Select DX report details can be viewed here.

Merv, K9FD, continues to experience storms located off of the island which are no doubt elevating his noise level and impacting reception.  Operating WSPR through the session, he reported  wenty stations. He shared two-way WSPR reports with VK4YB, ZF1EJ and KL7L.  Merv received WSPR reports from 52 unique stations including JA1NQI, JA1PKG/2, JA3TVF, JH3XCU and VK2XGJ.  Select DX report details can be viewed here.

Jim, W5EST, presents, “Dive Deeper into 630m Voice Modes“:

“From a 630m operator’s point of view, what makes a voice mode different from a digital mode? I suggest a combination of at least some of these features:

– The transmitting operator speaks into a microphone and the receiving operator can listen soon after.

– Characteristics of a particular speaker’s human speech are at least somewhat perceptible by an operator at the receiving end. Audio play at RX at least somewhat resembles the particular transmitting operator’s actual speech.

– Communications content can be added and changed on the fly as the transmitting operator speaks.

– Content commences and ceases at will, with variable transmission duration.

     Among desirable features a 630m voice mode would have, consider these:

– Resilience at low SNRs, long-distance reach on 630m.

– Even if CW penetrates at lower SNRs, voice convenience can be attractive if you don’t know CW.

– Spectrum conservation: Occupied bandwidth should not exceed that of a SSB signal and preferably would be narrower–narrow enough to permit at least several concurrent QSOs on 630m.

– Low latency (delay) between commencement of transmission and intelligible play of received speech. For instance, regular SSB concurrently transmits as you speak into the microphone. SSB comes out of the RX speaker or headphones almost as soon as it’s spoken at the TX end. An SDR and its PC might introduce a little delay on regular SSB but not enough to matter here.

– Transmission bandwidth should be narrow enough to fit a narrow antenna resonance curve if the LF/MF TX antenna is high-Q.  If high-Q, the antenna system might itself filter regular SSB.

– 630m/2200m voice QSO content should be optionally recordable for subsequent playback and e-mailing.

On HF, SSB is a favorite voice mode thanks to generally far-higher TX power levels and availability of beam antennas on many of the bands.  Also, most of the HF phone bands are wide enough to accommodate numerous SSB QSOs at once.  And HF antennas don’t risk filtering SSB.

On HF, we ham radio operators can generally take for granted the desirable features that SSB confers. On 630m and 2200m, by contrast, life with voice modes gets more challenging–and more interesting!

How can we live with a single SSB “channel” on 630m? On 630m, geographic separation can allow simultaneous daytime voice QSOs in a single 3 KHz SSB bandwidth at 476-479 KHz.  Chances are, such daytime QSOs would mostly be at ground wave range, say within 400 km.

Nighttime 630m voice in a single 3 KHz SSB bandwidth would be accessible by stations over considerably wider distances. 630m stations could experiment with alternative operating techniques such as 1) usual CQ to seek ad hoc QSOs, or 2) listen and wait until a QSO is completed by others and then call one of them to begin another QSO. 3) Another alternative would do a 3-way QSO or roundtable among more than two stations in the SSB bandwidth. 4) A further alternative would operate less formally than a net but coordinate a little more than in a multi-way QSO. For instance, one “hub” station who receives most stations in a region could encourage voice QSOs and stand by for QSOs between stations that a hub station operator hears.

On another blog day, let’s dive into more technical aspects of narrower band voice modes and what they mean for 630m/2200m operations.  TU & GL!”
