Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Extraordinary night for trans-Atlantic openings including those from G0MRF who was reported deep into the US; Trans-Pacific openings were average; W0YSE and N6PIG/7 effectively use JT9 for free-form on air keyboard-to-keyboard chat

The North American mainland was lightning free but storms persist through the Caribbean into the Atlantic ocean.  Southern Europe continues to experience active weather conditions and Japan returned to more widespread storms through parts of the session.  Storms in Australia impacted the Northern region, leaving many of the population centers along the eastern and southern coast storm free but they continue to experience high noise levels.  John, VK2XGJ, indicated that this year’s weather has been far worse than what was experienced this time last year.

Geomagnetic conditions were quiet to unsettled. The Bz is pointing to the South this morning and solar wind velocities are averaging near 470 km/s.  DST values remain near the centerline but decreased slightly during an unsettled reporting period.

Joe, DF2JP, tested a new transmit antenna on the air for the first time during this session, using 60-watt TPO.  Joe indicates that the antenna is “…13m high, with 4 roof capacities of different lengths, altogether approx. 80m. Measurements showed an antenna capacity of 590 pF so only 200μH were missing for the resonance.

Using WSPR, Joe received reports from 112 stations on three continents including,

Even if you are not participating in the ARRL’s 2018 grid chase, please take the time to upload your logs to LoTW so that those who are participating can receive credit.  I know there are a lot of operators that don’t like the ARRL and refuse to participate in their programs – I don’t like them in their current state either and have ceased participation in most of their programs – but this is a good opportunity to grow activity on the band and expose hams to actual operating, not just mindless beaconing.  If you have uploaded your logs, thank you.

The following stations provided reports of their two-way QSO’s and/or any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):

Mal, G3KEV, reported CW QSO’s with IK2DED, I2BBJ, DK1HW and  F5OFK.

Hans-Albrecht, DK8ND, reported  CW QSO’s with  IK2DED, G3KEV and DJ6CB.  Of his weekend operating, he indicated  that “…On Saturday it was fine to listen to the strong Ita-stns. Seven Stns in a weekend isn’t much, but on MW I hardly could get more, as I remember.  The ndb BIA (472,99 kHz) was this weekend very weak, often lost in noise in my receiver EKD300, IF-BW 100Hz, AF-BW abt 30 Hz followed by cw-stereo phaser and a ANL Headphone (mil-type). I cannot say until now, whether the rx is not sensitive enough or it is the Aereal, operated without radials, that my receiving results are not really good. Areal is built on a clay slope, facing north-west, so there is always dewfall.”

Neil, W0YSE, reported a JT9 QSO that really kept him on his toes and he wondered what we can do to promote a real chat mode for the band.  He offered these extensive comments and statistics for the session:

“My only JT9 activity last night was with Bill, N6PIG in south central WA, about 163 miles east of me. It was fun to try and “chat” using this mode. You have to be alert and fast to think of “free messages” of less than 14 characters on the fly, and within 10 seconds. Most of our replies to each other looked out-of-sequence, or delayed, as a result, but it was fun anyway. 

Here is most of that QSO from my TX screen :

After Bill’s chat I saw a comment by Robert, KR7O who was “reading the mail”. He wanted us to “keep the chat going”. There is definitely a need for a chat mode on this band, but it is probably limited to those stations who are not so distant from us. The weaker signals need to stick to the standard “canned” messages in order to get thru to the other station, as Larry W7IUV mentioned to me awhile ago.

That being said, I suggest GMSK15, which is possible at a -15 SNR with a narrow BW of about 25 hz. Another one is MFSK4 at about the same SNR, altho’ it is much wider and needs to be done above the WSPR segment. The only other chat mode is WSQ which is very narrow but also very slow ( like 5 wpm at best and slower when you use upper case, etc).

My WSPR was heard by 32 stations. Very similar to recent results. Here are the “DX” stations I reached this session (+ KL7L):

…and here are the 10 that I heard on WSPR: K5DNL, K9FD, KA7OEI, KR6LA, KR7O, NU6O, VA7MM, W1IR, W7IUV”

Al, K2BLA, reported that he “Worked N1BUG for a new one overall on 630m, WA9CGZ for a new 2018 grid and K1UTI and WB4JWM on JT9. WSPR: Heard 19 including G0MRF; heard by 58 including K9FD and EA8LFK. Hearing and being heard in EU is not so easy this far south.” 

Ken, K5DNL, reported a JT9 QSO with WB4JWM.  Using WSPR overnight, Ken reported 23 stations including G0MRF and he received reports from 89 unique station including KL7L,  K9FD (/KH6),  F59706,  EA8BFK,  F1AFJ,  F6GEX,  EA1BNF and nine Canadian stations.  Be sure to check out Ken’s website as he has amplifiers and other products for sale that might help you get on the air or improve your signal and situation.

Tom, WB4JWM, reported a JT9 QSO with K3MF and N1BUG.

Robert, KR7O, reported that “W7IUV was in (marginally) all day, except for the local noon hour.  Seems we are stuck in a rut, but W1IR was in from 0518-0954Z (33/-20) Single spots of N1BUG, K2BLA and W4KZK (first reception) for the only other TC.  K9FD didnt appear until 0508z.  Except for the JT9 mini-marathon QSO between W0YSE-K6PIG, there is nothing else worth noting.

K9FD 84 spots, -8

VK4YB 2 spots, -28

The early evening was slow at KB5NJD.  A JT9 QSO was completed with WB4JWM relatively early in the evening.  Tom was plenty strong here but he reported quite a bit of QSB on my signal.  Tom also reported a GMSK transmission that I made at 1300 Hz following our JT9 QSO.  I made a number of calls on 474.5 kHz CW to no avail and briefly heard K4EJQ on 473.8 kHz at a weaker signal than typical for him.  I heard a strong tuner-upper for a period around 472.5 briefly but the signal never ID’ed.   This morning I made a couple of late calls on CW but no QSO’s were completed.  W3TS was detected briefly near his sunrise but well below QSO levels on CW.  We may be host to an ice storm this evening so I expect to be QRT during the coming session although its possible that I will be able to listen.
