Welcome to another incredible (and we mean "in-cred-ible") edition of The Weekender. In this episode, we talk about some upcoming QSO parties for various US states, some special event stations coming up, SSTV from the ISS, NixOS, upcoming Linux and Open Source conferences, a Lowland Scotch whisky, really good ham sandwiches and drinking pine trees. All that and a lot more. Thanks for listening!

Although Canadian amateurs have had the 630m band for a few years now, the arrival of U.S. amateurs on the band last fall has been a game changer in terms of activity ... it's almost like starting fresh once again, hence the "Winter One" title!


The steady arrival of new stations on the band was exciting to see and the increase in activity made nightly band-checking mandatory in order to keep up with the new arrivals. Not totally unexpected, a high percentage of the new stations were located in the eastern part of the country where ham populations are higher, giving even more incentive to watch propagation trends for those 'special' nights to put some of the new arrivals in the log.

Over the winter DX season I worked 37 'new' U.S. stations in 23 different states. Of these 23 states, 11 were on CW while 12 were on JT9. Many of the JT9 contacts could have been made on CW at the time, had that been the operating mode chosen.


Hopefully the band will see an increase in CW activity next year as activity continues to grow. It is certainly much easier to get a capable CW signal on the air than a digital one and that is what many decided to do to get a quick start, while going the transverter route was the method chosen by most.

After being active all winter, the biggest surprise for me about 630m was just how little actual power is needed to exchange coast-to-coast signals, especially when using the weak-signal digital JT9 QSO mode.

Almost every new station that I worked was running less than 100 watts of total per output (TPO). A large number of these stations were in the 20 watt TPO range which I really found astounding, considering the relatively poor efficiencies of typical backyard antenna systems on this band. Propagation, always the great equalizer, was certainly playing a major role at times and watching conditions change from night to night was an education in itself.

K9MRI - 22W / 72' vertical wire / 140' tophat (72' x -140')

K9FD/KH6 - 100W / 70' x 70' inverted-L

K0KE (CW) - 75W / 70' x 50' inverted-L

WA9CGZ - 100W / base-loaded 160m inverted-L

N1BUG - 20W / inverted-L

KC3OL - 15W / base-loaded 'T'

K8TV - 3W eirp / 55' x 150' 'T'

K9KFR - 20W / 80' wire vertical

KA7OEI (CW) - 25W / 200' circular loop at 30'

K5DOG - 16W / 275' vertical loop

KC4SIT - 60W / inverted-L

As on most bands, allowable power is limited, but on LF and MF, the limits are stated in EIRP and not TPO. Hams are limited to 5W EIRP on 630m which may not sound like much but a large number of the stations worked this winter were worked while I was running around 2-3W EIRP which often seems to be plenty when using JT9.

Although Canada's west coast is now well-represented on 630m, it would be really great to see some interest and station building from provinces to the east ... VE6, VE5, VE4 ... The fast-approaching warmer weather should provide the ideal opportunity to get any needed antenna work squared away before the next DX season begins along with its anti-antenna building winter weather!

If you are one of many amateurs that may have been contemplating some 630m work but were discouraged about antenna sizes or having to generate gobs of power, hopefully the above information will encourage you to get on the band and join the fun.

If the ham community continues to maintain a rigid stance on the ARRL’s expanded HF petition, it will lose! The youth of today have no need for antiquated communication techniques that require they take the time to study and pass a test. Today’s world is not lacking for communication ability — quite the contrary — and today’s young folks are very adept at navigating it, and staying in touch and up to date much more than we ever were.

What about power down emergency situations? Cellular comms not reliable in disasters? The youth of today figure they will deal with that when the time arrives. Misguided? Perhaps, but that is what the ham community is up against, plus we do not go out of our way to try to improve/modernize our image much. Local nets are typically check-ins (for numbers), morning coffee, work travel hand waves, weather-at-my-house type conversations, not what today’s average youth find appealing.

Today they can pick up a cell phone and do any of those with a few keystrokes, and beyond that, no propagation concerns, noise is rarely an issue, imaging is instantaneous and unrestricted (no need for Dad’s Playboy!), and lest we forget: NO STUDY/NO TEST. Instant gratification goes a long way in selling a product.

The ham community is, in their eyes for old guys and gals who have nothing much to do, are not socially connected, are willing to work hard at making connections, and satisfied with a less than fantastic communication environment. I am not saying they or we are incorrect, just that is the state of affairs at the outset. We have yet to discuss the varied equipment and its uses, range limitations of that equipment, maintenance requirements, and on top of all of that software, connecting cables, and computer considerations. The fact that we can talk around the world no longer holds the mystique of our youth. They have been able to do that since birth, almost.

All I am trying to say here is simply this: our ham equipment is state-of-the-art, capable of doing a wonderful job when the situation allows, skill prevails, or just plain old LUCK takes over. The ham community for the most part is a melting pot of great people worldwide, and there is a self-satisfaction in accomplishing that particular DX contact, copying the satellite telemetry, or finding out how old Joe is across town. How much of that satisfaction is common knowledge to the youth of today? If we want the “Hobby” to continue and flourish, we have got to make it more appealing, open our world wider to theirs, prove the value and worth of what we do “for fun” and social connection, and introduce them to that self-satisfaction we enjoy.

There truly is hope. It is not all doom and gloom. We have a local 13-year old calling a 2m net here every Friday night. He and his dad got their ticket the same day. Hmmm, maybe that says something?

That to me appears to be the crux of our APPEAL problem. If it takes opening up a section of HF for them to experience it, then I am all for it. Allow the young folks we have the opportunity to show off to their peers, the proverbial “WOOHOO!” made that contact moment, or a “that is a station in a country far flung from here” moment! And hopefully the resultant, “WOW! That is cool” moment. If we fail to pass this on successfully then our greatest fear may become reality someday, “A world without communication!” And who among us really wants that?

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.

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.
