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

Current Operating Frequency and Mode

CQ 474.5 kHz CW and alternately tuning 472 kHz - 475 kHz for signals.

Many reporting a strong session including mid and high latitude transcontinental openings as geomagnetic conditions improve but strong storms across North America continue to impact listening; Trans-Pacific openings are hot including WI2XBQ -> JR1IZM

The details for October 4, 2016 can be viewed here.

The UTC amateur registration database is hereEven if you don’t think you will use these bands, REGISTER!  Doing so prevents UTC from future PLC coordination in these bands near your QTH.  While amateur interference to PLC systems is a myth and PLC systems are migrating away from RF, there is no reason to give them a reason to do something weird in the future.

HERE are a  few mode specific comments addressing where modes are located now and probably where they are best placed in the future.

 

North America is once again draped with a strong storm system generating lots of noise from Ontario to Mexico.  The Caribbean through the Yucatan also experienced numerous lighting-producing storms.  Watch those antennas!

11-hour North American lightning summary

 

Geomagnetic conditions continue at quiet to elevated-quiet levels. The Bz is pointing slightly to the North and solar wind velocities are averaging near 360 km/s.  DST values have generally been stable as they ride the centerline, in some cases moving into positive territory, suggesting more favorable high latitude propagation and general overall stability.

 

 

 

Roelof, PA0RDT, reported that trans-Atlantic propagation was improving again, referencing VO1NA’s QRSS10 CW beacon on 477.7 kHz.

Neil, W0YSE/7 / WG2XSV, operated WSPR and continued his digital mode evaluation using an Internet-based SDR in Alberta, Canada.  He provided these details:

“28 unique WSPR spotters: Here are those over 1000 km from me. Nice to see K8PZ and WE2XPQ in the list this morning.

…and I heard only these 5: WH2XCR, WH2XXP, WI2XBQ, WH2XGP, and WI

Here are results of my testing various modes being received at the ve6jy SDR near Edmonton, AB this morning:

The following modes were successful: WSPR, JT9, FT8, JT65, MFSK4 (but only ~50% copy on this one).

Modes that did not decode were: QRA64, CW, OLIVIA 4/250, THOR4.”

Phil, VE3CIQ, indicates strong local reports but nothing further than 1200 km from his location in Ontario.

John, WA3ETD / WG2XKA, indicates that he provided reports for thirteen WSPR stations and he received reports from 33 unique stations.  John added that this was the “…Best session of the new season so far…Much improved condx with the PNW wide open…Noise finally appears to be abating.  Higher lat barrier might finally be breaking down ‘6xh and 6jy spotting…”

Rick, W7RNB / WI2XJQ, indicates that it was a much better session which included reports for him on the East coast for the first time this season.  He provided reports for seven WSPR stations and he received reports from 31 unique stations.  Rick’s unique report details can be viewed here.

Al, K2BLA / WI2XBV, provided reports for eleven WSPR stations and he received reports from thirty unique stations in just two-hours of operating.  Al added that he received reports from “…VE3,6,7 and XCR 6 of the the 30 over 3000km low/moderate noise.”  Al also reported that he found the cause of local interference and offers these comments and recommendations for others that might be in a similar situation.

Ernie, KC4SIT / WI2XQU, reported that:

“Propagation was not as good for WI2XQU as the night before; the prime example being that Doug WH2XZO and I both reached WH2XCR the session before last but only Doug reached the needed 7357 km distance last night. I had my signal decoded by 39 stations last session as did Doug but continue to notice that our stations are reaching into different grid squares. Session before last Doug reached 3 uniques grids and I reached 1 unique. I’ll continue to study this pattern.

Doug and I are both in the EM85 grid. Doug also demonstrates what we all know, multiple type receive antennas are a big help on 630. Doug decoded 11 stations to my 3. Grid EM85 continues to be blessed will an active base of transmit and receive stations on the 630 band.”

Mike, WA3TTS, reported that he decoded sixteen legitimate WSPR stations overnight.  Mike also provided these improved, detailed instructions that allow operators who wish to modify their WSPR data files prior to upload in order to clean up “bogus” call signs.  In this version Mike is using command line instructions to sort the dataset, making the entire process of “search and destroy” easier than traditional visual inspection.  Mike asks that WSPR operators consider manually processing their data and uploading their logs as the process only take a few minutes but can really clean up the final product.  Mike provided the following comments and details of the session:

“My EWE antennas were pointed NE early and NW late from about 0300 to SR.

Dave, N4DB, reported that he decoded eleven WSPR stations overnight.

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, indicated “code 3, moderate propagation, increasing QRN.” at 1042z.  He received reports from 7L1RLL4, CF7MM, JA1PKG, JA1PKG/2, JA3TVF, JE1JDL, JH1INM, JR1IZM, JH3XCU, KJ6MKI, N6KOG, N1VF, VA7JX, VE6JY, VE6XH, VE7BDQ, VE7AB, KU4XR, VE7CA, VE7SL, W6SFH, W7IUV, WE2XPQ, ZF1EJ and WW6D. He shared two-way reports with WH2XCR, WI2XBQ and WH2XGP.

Joe, NU6O / WI2XBQ, indicates that this was a very good session with good trans-Pacific openings.  He provided reports for eight WSPR stations and he received reports from 31 unique stations including ZL2AFP and JR1IZM.  He shared two-way reports with VK4YB.  Joe added that he was “…also heard by KU4XR. All the DX spots were weak, at the detection threshold, but prop is improving. Looking forward to opening night!”

Ward, K7PO / WH2XXP, received reports from 54 unique stations including  ZL2AFP and VK4YB.

Larry, W7IUV / WH2XGP, provided reports for thirteen WSPR stations and he received reports from 53 unique stations including ZL2AFP.   He shared two-way reports with VK4YB.  As W7IUV, Larry provided reports for nine WSPR stations including VK4YB.  Larry also noted that he is now using a modified QRP Labs SDR on 630-meters for receive with the western antenna labeled as W7IUV.

Kevin, KL7KY, is a recent new addition to the listening corp on 630-meters.  Laurence, KL7L,  reported that his current antenna is on the order of 190 foot tall and he is an active 160-meter operator that many may remember when his call sign was  NL7Z (it’s  been reassigned).  As Kevin is preparing to move to a different QTH within Alaska, his antennas and activity may be a bit fluid for a while.  During this session, he provided reports for WE2XPQ and WH2XCR.

Merv, K9FD/KH6 / WH2XCR, provided reports for eleven WSPR stations. He shared two-way reports with VK4YB, ZF1EJ and WE2XPQ.  Merv received reports from 42 unique stations including 7L1RLL4, JA1NQI, JA1PKG, JA1PKG/2, JA3TVF, JE1JDL, JH3XCU, JR1IZM, KL7L, VK2XGJ, VK7TW,  ZL4EI and ZL2AFP.   Many of the long haul JA and VK reports continued up to and even following sunrise.  DX report details can be viewed here.
