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.

Best trans-Atlantic openings so far this season while trans-Pacific openings fail to produce many results; Noisy night in North America and parts of Oceania

The details for October 6, 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.

 

More storms from the Southwest through the central US and into the Midwest created lots of noise through the evening and this morning.  Another hurricane is churning in the Gulf of Mexico, approaching the gulf coast which is always fun.  The Caribbean is also experiencing a lot of lightning activity and I’m a little surprise that ZF1EJ didn’t report an overnight shutdown.  A few storms were active off of the Atlantic coast of Florida in addition to the coastal New York / New Jersey area.

Geomagnetic conditions continue to range from quiet to elevated-quiet levels.   Solarham indicates that unsettled conditions are on the horizon, however.  The Bz is near unity this morning and solar wind velocities are elevated,  averaging near 450 km/s.  DST values have generally followed the center line even moving into positive territory in some cases but a general trend over a longer time scale suggests that the levels are decreasing overall.

 

 

 

There were no reverse beacon network reports registered for 630-meters during this session in spite of CW activity in North America.

Roelof, PA0RDT, reported on the RSGB-LF reflectors that VO1NA’s CW signal on 477.7 kHz was received through the night but experienced deep fades.

It appears that Mark, VA7MM, was attempting to arrange a cross-band QSO with Russ, KE7ADL.  Its unclear about whether a QSO was completed and what the cross-band frequency was to be.  All of this occurred between 0330z and 0500z.

Jim, W4BCX / WI2XRM, received reports from EA8BFK.

Dave, AA1A / WD2XSH/17, received reports from DH5RAE, EI8JK, G8HUH, and PA0RDT.

Neil, W0YSE/7 / WG2XSV, reported transcontinental openings and continued experiments from Vancouver, Washington.  He submitted these comments and statistics:

“WG2XSV got waaay eastward into Tennessee to KU4XR this session as well as K8PZ. I was also heard by a new one in AK, KL7KY, along with Laurence, WE2XPQ in AK. Of course Merv in HI is almost always hearing me, and visa-versa.

Here are my results RX and TX:

WG2XSV was Hearing: WD2XSH/20, WE2XPQ, WH2XCR, WH2XGP, WH2XXP, WI2XBQ, WI2XJQ

and Heard by: CF7MM, K8PZ, KJ6MKI, KL7KY, KO6KL, KU4XR, KU7Z, N6KOG, N7VXA, VA7JX, VE6JY, VE6XH, VE7AB, VE7BDQ, VE7BPB, VE7SL, W0YSE/VE6, W0YSE/VE7, W6SFH, W6YQ, W7IUV/W, W7WKR, WD2XSH/20, WE2XPQ, WH2XCR, WH2XGP, WI2XJQ, WINSWL, WJ2XBZ, WW6D

Note that  W0YSE/VE6, W0YSE/VE7 are from kiwiSDR’s in Edmonton, AB and Victoria, BC respectively as I am experimenting with them trying various modes, in case anyone is getting decodes from them and wondering “what’s up” . My thanks to operators of both kiwiSDR’s for making their equipment available on the web for us.”

Rick, W7RNB / WI2XJQ, provided reports for seven WSPR stations and he received reports from 32 unique stations.  Rick’s unique report details can be viewed here.

Joe, WA9CGZ / WI2XSV, reported that he received WSPR decodes from 36 unique stations which was a new record for his station.

Ernie, KC4SIT / WI2XQU, reported that “Things seemed slightly less active at WI2XQU with 37 decodes of my signal last session compared to the 41 for the session before.”

David, N1DAY / WI2XUF, reported good propagation in addition to some attempts to accurately measure his system field strength during this session:

“Last night was a good night here at WI2XQU in spite of my failed attempts to locate and destroy a new RF interference source.  I just hope that it is not coming from a neighbors house.  I provided a total of 13 RX spots last night with 6 being greater than 1000 Km.
Also, my Heliogenosis Field strength meter arrived yesterday.  It is a nifty little device for $129 and they claim it is accurate to within .05%.  In an initial test, I measured a 5 watt 40M transmission at 8 points around my MF antenna at 4 meters distance at a height of 5 feet and was shocked at the findings  The readings varied from a high of 0.09 mW/cm2 going north/northeast to 0.01 mW/cm2 to the south.  This suggests that the antenna is not nearly as omnidirectional as I thought it was.  I will be conducting the 630M tests in the next several days and comparing them to readings on XQU and XZO’s antennas.  I am hopeful that it will explain some of the differences we are seeing in reports out of EM85.  I am also hopeful that this approach will result in more accurate determination of amplification needed to generate a true 5W EIRP on 630M as it will eliminate the big unknowns of coil impact on transmitted power and estimated gain which is largely derived from the various NEC2 modeling programs.
For anyone interested, equations for translating 5W EIRP to mw/cm2 can be found at the following websites. Although different approaches, I have verified that both equations result in the exact same results.

Al, K2BLA / WI2XBV, provided reports for eleven WSPR stations and he received reports from thirty unique stations in spite of operating at half power due to elevated SWR resulting from wet insulators in his system.  Al also reported my CQ’s on CW at RST 589.

Mike, WA3TTS, reported that he decoded thirteen WSPR stations overnight, adding that “…Antennas to NE early and then to SW after 0400 UTC. Best DX XSH/20 followed by XGP, XXP, ZF1EJ, etc.”

Dave, N4DB,  indicates quiet band conditions in Virginia.  He provided reports for eight WSPR stations.

Larry, W7IUV / WH2XGP, indicated that it was a “Decent path to east coast, heard some guys that I have not decoded in a long time.”  He provided reports for eleven WSPR stations and he received reports from 57 unique stations including ZL2AFP and ZL1EE. As W7IUV, Larry provided reports for nine WSPR stations.  Larry also indicated that he has completed another configuration change at his station: “XGP RX on 800′ east BOG, W7IUV/W SDR on west RX ant.”

I called CQ on 474.5 kHz CW through the sunset period, beginning around 0004z, QRTing at 0105z after full darkness.  Noise was elevated and I had no reverse beacon network reports or additional QSO’s.  This morning I repeated the process, beginning at 1010z, and experienced similar result.  I received no reverse beacon network reports although AA4VV was not active and noise may have been high in VE6.  I QRT’ed at 1200z and note continued high band noise.  Al, K2BLA / WI2XBV, located in Florida, reported that I was RST 589 this morning.
