IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet. That includes stations using fake or pirated call signs. Please continue to be patient and let the FCC finish their processes. UPDATED: Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.
Storms were widespread again, particularly in the Caribbean, South, West, and portions of the Midwest. Al, K2BLA / WI2XBV, reported steady S9 noise in Florida.
Geomagnetic conditions are at unsettled levels and rising. Storm levels are expected at any time. The Bz is at an incredible -22 nT, pointing strongly to the South and solar wind velocities are averaging near 515 km/s. Satellites have confirmed the passage of the CME shockwave overnight. G1 storm levels are expected. DST values experienced textbook behavior, exhibiting an increase just prior to decreasing significantly.
Rudy, N6LF / WD2XSH/20, recently posted the following on the 600-meter research group email reflector about his recent antenna rebuild:
“I’ve recently rebuilt my 630m transmitting antenna to see if an elevated counterpoise would give results comparable to 128 150′ radials on the ground. This work seems to show that a simple counterpoise using far less wire can work very well. For a description go to: www.antennasbyn6lf.com .”
David, N1DAY / WI2XUF, provided this very extensive report of his recent activities:
“Conditions continue to be brutal here in the southern Appalachian mountains as they are across a lot of the US. We seem to have fallen into a daily pattern of late afternoon and evening electrical storms that are playing havoc with radio communications. In spite of this, I am still managing to make some 630M contacts and have been working on my receive antenna performance. I installed a relay on my Marconi Tee antenna so that I can switch the 630M loading coil out of the antenna circuit during receive, and that has resulted in receive performance comparable to my dedicated receive inverted L antenna. A few weeks ago, this resulted in a daily best performance at my station for 21 spots in a 24 hour cycle. Also, I have returned to the multi-turn loop antenna developed by VE7SL that is described on your website for additional experimentation.Initially I was disappointed in the loop antenna’s performance with a preamplifier designed by W7IUV at the base of the antenna. But after a bit of additional research, I discovered that the low band performance of the preamp could be improved by replacing the 0.1 uf coupling capacitors with 2.2uf capacitors. This modification to the preamp was completed last week and tests so far have found a marked improvement in antenna performance from 630M all the way up to 40M. SNR reports between the inverted L and the loop antenna are now within what I would consider normal cycle to cycle receive variation and the better performance on specific stations seems to be split between the inverted L and the loop antenna. I will continue to study and quantify this over the next several weeks using WSPR reports.What I have seen so far with the loop antenna and the modified W7IUV preamp suggests that the loop could be a good alternative to bigger antennas at locations where space is at a premium. Also, I live in an antenna restricted HOA so hiding my antennas is a must (I currently have 9 daily violations hidden on the property). The loop is in a hidden area as well, but given its size, I may deploy it as a temporary antenna in different locations at night to see if I can squeeze a few more dB of performance out of the loop. I will continue to use my inverted L as my primary receive antenna, but the loop is interesting and I like to experiment.”
Neil, W0YSE/7 / WG2XSV, reports that was decoded by thirteen West coast stations in addition to WH2XCR who provided seven reports for Neil, best at -22 dB S/N. Neil indicates that he decoded three WSPR stations and notes that propagation seemed down.
Trans-Pacific report details, excluding E51, KL7, and KH6, can be viewed here.
Joe, NU6O / WI2XBQ, received reports from eighteen unique stations including ZL2AFP.
Larry, W7IUV / WH2XGP, provided reports for three WSPR stations and he received reports from 21 unique stations including ZL2AFP. As W7IUV, Larry provided reports for five WSPR stations.
Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, received reports from four unique stations including WH2XCR.
Warwick, E51WL, provided reports for six WSPR stations. Report details can be viewed here.
Laurence, KL7L / WE2XPQ, operated in a receive-only capacity and provided reports for two WSPR stations.
Merv, K9FD/KH6 / WH2XCR, provided reports for VK3HP, VK5FQ, and ZF1EJ. He shared two-way reports with VK4YB and he received reports from WE2XPQ, E51WL, VK2XGJ, ZL2AFP, and ZL2BCG. Merv’s DX report details can be viewed here.
