Weekly Propagation Summary – 2018 Jul 23 16:10 UTC

Weekly Propagation Summary (2018 Jul 23 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Jul 23 0031 UTC.

Highlights of Solar and Geomagnetic Activity 16 – 22 July 2018

Solar activity was very low throughout the period. Region 2716 (N16, L=199, class/area=Axx/10 on 21 Jul) was briefly the sole active region with sunspots, but was largely unproductive. No Earth-directed CMEs were observed this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached moderate levels on 22 Jul with normal levels observed through the rest of the period.

Geomagnetic field activity was quiet to unsettled on 16-17, 20-21 Jul with generally quiet conditions observed throughout the remainder of the period. The activity on 20-21 Jul was associated with the weak influence of a positive polarity coronal hole high speed stream.

Forecast of Solar and Geomagnetic Activity 23 July – 18 August 2018

Solar activity is expected to be very low throughout the outlook 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 23-31 Jul and moderate levels are expected on 01-11, and 18 Aug. Normal levels are expected throughout the remainder of the outlook period.

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 24 Jul due to the influence of a negative polarity coronal hole high speed stream. Active conditions are expected on 23, 25 Jul and 17 Aug due to the influence of multiple, recurrent coronal hole high speed streams. Quiet and quiet to unsettled conditions are expected throughout the remainder of the outlook period.

6m … Where’d The Magic Go?


This summer's 6m sporadic-E (Es) DX season is now well past the half-way mark and things have been different ... a lot different. For me, the past 40 plus summers of activity on the magic band have always been interesting, if not down right exciting ... particularly when the band opens to Europe from the west coast.



These usually very short-lived paths have been my main interest for the past several years and the bread and butter mode is normally a fast CW exchange, usually taking less than 20 seconds before signals would vanish, as the always quirky west coast path to Europe would jump to another region. But this has all changed dramatically.

As well, it seems that this summer, the normal SSB and CW modes have been largely abandoned by a huge percentage of the crowd, in favor of FT8, the weak-signal digital QSO mode originally developed with 6m in mind.

I have seen many strong openings involving loud FT8 signals from various parts of North America but when tuning down to the CW/SSB section of the band, found nothing but ghostly silence! Gone are the familiar voices of friends met every summer for decades or the recognition of an old friend's fist on CW ... for me personally, most of the magic was missing this summer. I wonder if this is all part of the natural evolution of amateur radio or does the FT8 revolution signal the long term fate for many of the older conventional modes?

There appears to be a lot of new activity brought to the band by this mode, and many are experiencing the magic band for the first time. I have heard at least two dozen or more VE7 calls on 6m this summer that I have never heard before and this is a very positive thing! From what I can tell, many of the new stations on the band may have makeshift or simple antennas, such as verticals or dipoles and not something larger and are just getting their feet wet on the band.

FT8 allows for two-way weak signal work (a few db below audible limits) that the traditional modes would not support, and simpler stations, without big antennas, can now join the fun. I often see many of the newer stations calling CQ but not hearing their numerous replies, which leads me to think that their receive-capability does not yet match their transmit-erp ... perhaps they just have a lot of local noise or are running more power than they can properly deal with, something they should think about. Often the new FT8 stations will continually CQ, sometimes as long as 90 minutes at a time and create a lot of unnecessary and waterfall obliterating QRM on the band for those that do have good antennas and can hear what they do not. I'll do another blog later regarding FT8 on 6m, and what I have observed this summer.

Here on the west coast, up until last summer, it was fairly normal to have a few short-lived Es openings to Europe. You had to always be on your toes to catch these as they would vanish as suddenly as they appeared. The best of these was back in June of 2012 when a mid-morning opening produced 31 CW contacts in DL, F, SP, CT, ON, GM, IT, LZ, EI, G, S5, I and EA8. Nine new countries were put in the log that morning as the Es clouds danced around, shifting the propagation from one country to another, every other minute. This was the magic band at its best!

Like last summer, this year has produced almost zero trans-Atlantic propagation from VE7 land, other than contacts with CT1 and EA8, both on FT8. Perhaps some external factors are changing the band enough that this path will vanish permanently ... only time will tell. 
Dave, K7RWT, recently pondered if it may have something to do with the north magnetic pole migration over the past several years as it moves to the north-northwest at ~60km per year.

Track the pole's movement here.
Most mornings, the Europeans are into the east coast early, often times making into the central states and occasionally into the southwestern states:

Later in the afternoon, it has not been unusual to see widespread JA to North America action, usually going straight overhead and as far back as the New England states and down to Florida!

July 20th courtesy: http://www.on4kst.org/chat/index.php

There have been several openings between here and JA, sometimes lasting for several hours. So far I've worked about 200 JAs this summer and judging by the flood of daily QSLs arriving from Japan, many are newcomers to the band (the FT8 effect?), often indicating that I was their 'first VE' contact on 6m.



Unlike the west coast to Europe openings, the JA-NA path appears to be growing, this summer particularly ... perhaps it's just those extra few db provided by FT8 that is responsible.

One particularly interesting 'opening' from here happened in the wee hours, starting just after 2300 local time and ending just after 0200, as all west coast operators were sawing logs. A morning check of my FT8 decodes indicated many strong signals from Japan, Taiwan, China, Korea and Hong Kong. I'm sorry that I missed out as the VR2 would have been a new country for me.

Overnight decodes July 8-9
 The non-JA stations heard were:

BM6GJL PL02
HL1BRU PM37
HL2IFR PM37
BG4QNE PM01
VR2VAZ OL72
BV2FB PL05
BV6CC PL03 

BV1EK PL05
BM3GFU PL04


Thanks to Paul, K7CW, for doggedly sorting through my all-night decode file which may be viewed in full here.

With just a couple of weeks left in the normal Es season, it will be interesting to see if FT8's extra few db will extend it longer than usual!

Initial setup of SunSDR2 Pro

To get the rig up and going it's not like most dial and knob rigs were you plug it in, turn it on and start spinning the VFO. This as most SDR rigs there has to be a talking relationship with the rig and PC. Lets start with the PC because there is going to be software on your PC that the SDR rig will have to communicate with and to do it well your PC should meet certain spec's.

Apache Labs ANAN 10 recommends an Intel i3 2ghz or better, 4 GB ram, screen resolution of 1280x1024 and a full duplex 1 GB ethernet card.

Flex radios knowledge base suggests Intel i3 or i5 quad core processor,  4GB ram for 32 bit OS and 8 GB ram for 64 bit OS, screen resolution of 1280x768 and the ability to support firewire. 

Sunsdr2 Pro recommends (located under "read it first") intel i3 1.6 ghz or higher, 8GB ram did not specify 32 or 64 bit OS, minimum screen resolution of 1024x600, LAN network card of 100 Mbps or 1 Gbps

Now mind you these in some cases are minimum specs but even to move up to the next level in a PC would not mean you are moving toward a high end gaming PC. Most of us have a PC at home for one reason or another and I would go out on a limb to say that most PC's at ham's homes would meet the minimum standard for SDR to function well. 
My SunSDR2 Pro's setup involves some minor PC techno wizbong maneuvering.......my SDR rig like most others communicate to the PC via a LAN cable and using an IP address. Now the Apache Labs ANAN 10 when powered on (if your LAN is correctly configured) an IP address should be automatically assigned in other words the rig and software should be communicating. The Flex radios are the same in regards to setup (again if your LAN is correctly configured) an IP address should be automatically assigned. This I believe is known as DHCP were the configuring is done automatically. For some reason the SunSDR2 Pro does not take advantage of this, you have to manually assign the IP address. It did not work out to well for me as I have 2 LAN options in my PC one is a card and the other is the one on the motherboard. When configuring the IP address I called up the wrong card (not the one the SDR rig was plugged into) Once I figured that out I was getting conflicts and issues. Long story short I have everything running now. I may email the Expert Electronics and ask why they chose this route and not DHCP.
The only (as far as I know) software this radio will work with is ExpertSDR software. Having said that I am very happy with the software and questions I have asked on the forum has been answered very promptly. It runs very smoothly on my PC and the waterfall looks great! The next post I will be looking at the ExpertSDR software.

Operating Tips for VHF SOTA

Bob K0NR SOTA Joyce K0JJWHere are some operating tips that I have found useful when doing Summits On The Air (SOTA) on VHF. I’ve been using VHF and higher frequencies for SOTA exclusively and have activated over 100 summits in Colorado (and other states such as California, Wyoming, New Mexico, North Carolina and Tennessee.)

The challenge with VHF and higher is that the radio range is limited compared with HF. (It really does help to bounce those signals off the ionosphere.) VHF propagation will vary depending on a lot of factors but for SOTA activations our range is typically 50 to 100 miles. In the backcountry of Colorado, a 50 mile radius may not include very many active radio amateurs, so you may come up short in terms of radio contacts.

First, take a look my blog posting about the basics: How To Do a VHF SOTA Activation

Next, here are some additional tips to having a successful activation:

Send Invitations

Get the word out to people that may be within range. I try to keep track of who I’ve worked in the past or know to be in a particular area and let them know when I’ll be activating. In some cases, I’ll go ahead and make a specific sked with a station. That is, we’ll meet on a particular frequency at a particular time, perhaps on CW or SSB for maximum weak signal performance.

Create an Alert and then Spot yourself on the sotawatch.org web page (using smartphone app).

Make Your Call

By the rules, SOTA contacts are always simplex, so on 2 meters the place to try is usually 146.52 MHz, the National Simplex Calling Frequency. (Some areas have established other 2m simplex frequencies to use for SOTA, so inquire locally.) This is the place to try calling.

Who are you going to find there? Hard to say. SOTA chasers will often listen to “five two”…that’s where they find SOTA activators. Also, there are radio hams that just like to hang out on 52…they like 2m fm operating but they don’t like repeaters so they listen here. You will also find that many mobile stations monitor 146.52 as they drive through rural areas. Basically, they are listening for anyone around but aren’t flipping from repeater to repeater as they change location. I’ll often hear 4WD enthusiasts, hikers, boaters, campers, etc. using Five Two.

Make It Sound Good

Realize that not everyone knows about SOTA so they may not know what the heck you are doing. Make a call such as this: “CQ CQ this is Kilo Zero November Romeo operating from Pikes Peak – Summits On The Air – anyone around?” Or “CQ 2 meters this is K0NR on Pikes Peak – Summits On The Air.”

Do a little bit of “selling” when you make your call. Sound like you are having fun.

Be Patient

Be patient. Sometimes it just takes time to accumulate your 4 QSOs to qualify for activator points. The few times I have been skunked on QSOs were when I did not have enough time, usually because storms were moving in. Keep calling every few minutes, taking a break once in a while to enjoy the view.

Try Other Frequencies

You may want to try other simplex frequencies, so know the band plan for the area you are activating in. Another trick is to get on a local 2m repeater and ask for someone to move over to simplex to work you. I have not had to do this very often but it does work. Have some of the local repeaters programmed into your radio.

Improve Your Station

Hopefully by now you know that using an HT with a rubber duck antenna is a bad idea. Get at least a half-wave vertical or roll-up j-pole antenna. Better yet, get a small yagi antenna to add 5 or 6 dB to your signal. It can make a big difference on who you can work. I’ve even started carrying a small 2m/70cm transceiver to get my 2m transmit power up to 30W.

Another angle is to use SSB and CW, which are much better for weak signal performance (compared to FM). This sets you up to work the serious VHF stations which tend to use these modes and have large high-gain antennas (horizontally polarized).
