Weekly Propagation Summary – 2018 Apr 09 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Apr 09 0536 UTC.
Highlights of Solar and Geomagnetic Activity 02 – 08 April 2018
Solar activity was at very low levels throughout the period with only a few low level B-class flare observed on 03 Apr from Region 2703 (S08, L=193, class/area Axx/010 on 31 Mar). No Earth-directed coronal mass ejections were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 02-04 Apr and at moderate levels on 05-08 Apr. The largest flux of the period was 2,150 pfu observed at 02/1915 UTC.
Geomagnetic field activity was mostly quiet with unsettled periods observed on 05 Apr. Solar wind speed began the period slightly enhanced near 470 km/s with total field around 4-5 nT. Solar wind speed declined to near 320 km/s by 04 April before increasing briefly to near 450 km/s by late on 05 Apr. Total field increased to a maximum of 9 nT at 05/2130 UTC. By 07 Apr, solar wind speed had decreased to 330-380 km/s while the total field decreased to 5 nT or less.
Forecast of Solar and Geomagnetic Activity 09 April – 05 May 2018
Solar activity is expected to be at very low levels throughout the forecast period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 12-30 Apr due to recurrent coronal hole high speed stream (CH HSS) influence.
Geomagnetic field activity is expected to be at unsettled to active levels on 10-16 Apr and again from 19-23 Apr with G1 (minor) storm levels likely on 10-11 Apr due to recurrent CH HSS effects.

My Rebuttal Regarding the Petition by ARRL to the FCC to Expand Technician-Class Privileges
This is my reply to many responses that I have been receiving on my original blog entry, located at this AmateurRadio.com website,(my shortened URL: https://g.nw7us.us/arrl2fccR2) as well as to the original video, posted in that blog entry.
I wish to reply to all of those who are against the idea of expanding the privileges of the Technician-class licensee, the expansions including the ability to operate Voice and Digital in limited slices in a subset of lower-than-Ten-Meter amateur radio shortwave allocations.
It seems to me, that…
…the issue is not one of Technician-class licensees wanting more privileges, as a whole. What the ARRL is addressing is the *lack* of desire by most current Techs to upgrade.
The logic behind the idea of expanding privileges concludes that if you give them a taste of lower-shortwave propagation and excitement (by moving past the CW-only restriction on the lower tech allocations), then they *will* want to upgrade.
This logic is already proven as applicable by the fact that the General class exists! All that this proposal will do is allow the Tech to experience what could be very attractive–just like for the General. If it worked in the past with Novice, Technician, General, Advanced, and Amateur Extra (exposing to all of HF, even if by way of a CW-only requirement), then it will work, now. The difference is that the CW-only requirement on lower HF bands is highly restrictive because the mode is no longer needed to operate on any frequency, and, most will not take the time to learn it just to see if they WANT to explore the lower HF bands, or ever upgrade.
The bottom line is that we should make the Tech ticket more relevant. The expansion is not dumbing down, nor does it give away the farm.
I discuss this original point in the two videos that were lower down in the original post:

and,

Thanks for reading, watching the videos, and having a useful dialog about this very important change to the amateur radio regulations in the USA.
P.S.,
That aside: This may, in the long term, reveal one of two possible truths:
1. There is no real need for three license classes. Two would suffice. General and Amateur Extra, or Technician (merged with General) and Amateur Extra.
2. There is no real need for three license classes. One would suffice. Make the test hard enough to cover the Extra-class material, and all material under that class, and merge everyone into one tested class. I believe that this has been tried in other countries, and it appears to work well.
I’ll be crucified for stating those ideas, but, hey, this is just a hobby.
Weekly Propagation Summary – 2018 Apr 02 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Apr 02 0443 UTC.
Highlights of Solar and Geomagnetic Activity 26 March – 01 April 2018
Solar activity was mostly at very low levels with the exception of 30 Mar when an isolated C4/Sf flare was observed at 30/0804 UTC from Region 2703 (S08, L=193, class/area Axx/010 on 31 Mar). Associated with the flare was a Type II radio sweep (805 km/s) and a coronal mass ejection (CME) off the east limb first observed at 30/0840 UTC in SOHO/LASCO C2 imagery. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels throughout the period with a maximum flux of 43,750 pfu observed at 28/2045 UTC.
Geomagnetic field activity began the period under continued effects from a negative polarity coronal hole high speed stream (CH HSS). Solar wind speed ranged from approximately 450-550 km/s on 26-27 Mar with total field between 2-8 nT. By 28-29 Mar, solar wind speeds slowly returned to nominal levels while a solar sector boundary crossing was observed around 29/0710 UTC into a positive sector. Solar wind speed showed a slight increase in speed to 380-480 km/s from 30 Mar-01 Apr with total field variable between 2-9 nT suggesting possible intermittent connections with a northern polar extension positive polarity CH HSS. The geomagnetic field was mostly quiet with periods of unsettled activity observed on 26-27 Mar and again on 31 Mar.
Forecast of Solar and Geomagnetic Activity 02 April – 28 April 2018
Solar activity is expected to be at very low levels with a slight chance for a C-class flare from 02-10 Apr due to potential further activity from Region 2703. Very low levels are expected through the rest of the period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels on 02-04 and 12-28 Apr due to CH HSS influence.
Geomagnetic field activity is expected to be at unsettled to active levels on 05-07, 10-16, 18-23 Apr with G1 (Minor) storm levels likely on 12 Apr due to recurrent CH HSS activity.

Short Demonstration of Using Ham Radio Deluxe with WSJT-X and FT8 Digital Mode
Ham Radio Deluxe can log your WSJT-X FT8, JT65A, and JT9 QSOs, via the JT-Alert software. This is a demonstration of my use of HRD and Logbook, during an FT8 QSO,today.
As some of you know, I have had some differences of opinion regarding the selection of frequencies chosen by the FT8 creators and advocates. Regardless, I do still use the mode. Here is proof:
Go ahead and share, if you would. And, please subscribe to my YouTube channel, as I will be creating many how-to videos in the near future.
Thanks and 73 … de NW7US
Opinions About ARRL Petition to FCC: Expand Technician HF Privileges!
In this video, I expound on another point of view regarding the ARRL petition to the FCC. The petition requests an expansion of operating privileges of Technician-class operators in the USA. The ARRL believes that giving broader shortwave access, using digital communications, to Technicians, will better entice the Techs to upgrade to General or Amateur Extra. In this video, I discuss this a bit.
If you are wondering why I’ve made a few videos about this topic, when the topic has been the hot item on many forums already, I believe that the drama will not cease until well after the FCC makes a decision, because this is a relevant topic, and one that has a significant impact on the amateur radio community at large. It is not a trivial conversation about which type of coax is best suited for Arctic field activity.
After some replies came from various viewers, I clarify my point. I stand corrected.
I failed to mention that there are a limited few slices of VOICE (SSB) spectrum on HF that the petition seeks for the Tech licensee. The ARRL states, “ARRL has asked the FCC to expand HF privileges for Technician licensees to include limited phone privileges on 75, 40, and 15 meters, plus RTTY and digital mode privileges on 80, 40, 15, and 10 meters.”
More specifically, “ARRL proposes to provide Technician licensees, present and future, with phone privileges at 3.900 to 4.000 MHz, 7.225 to 7.300 MHz, and 21.350 to 21.450 MHz, plus RTTY and digital privileges in current Technician allocations on 80, 40, 15, and 10 meters. The ARRL petition points out the explosion in popularity of various digital modes over the past 2 decades. Under the ARRL plan, the maximum HF power level for Technician operators would remain at 200 W PEP. The few remaining Novice licensees would gain no new privileges under the League’s proposal.” Reference: http://www.arrl.org/news/arrl-requests-expanded-hf-privileges-for-technician-licensees
My point holds: give some reason to desire to upgrade to a higher class. Do this by granting HF operations on lower bands (lower in frequency than 10 Meters), with more than a CW-only privilege.
If a tech can only use CW on 80m, but doesn’t know CW, then it is likely she won’t ever try making contacts on 80m. Hence, no exposure to the magic of 80-meter DX. If, however, the Tech can dabble with digital or limited SSB, on 80m, then she gets a real, practical exposure to the magic, and may well upgrade. Why do you think a General, who has limits, would ever upgrade? What am I missing here?
The following video expands this idea:

The truth is, I see a strong argument for just ONE license, permanent. Or a temporary entry-level training ticket, then the permanent. But, that would make us like some other countries. That can’t be good.
