I made a quick bike trip from Andover to the old Potter Place railroad station this afternoon. The fall colors were beautiful and I worked Texas and Germany.

I rode along the old Northern Rail route. It’s a rails to trails bike path now. I heaved my wire over an oak tree across from the station and sat down in the grass with the KX3. I was using a 30 foot wire as a vertical with an EARCHI 9:1 unun. I started out on 17 meters and heard N5WNG calling CQ from Dallas. He was really strong… we must have had an excellent path because Mike gave me a 599 and judging by his signal, I think it was a real report.

I didn’t hear any other stations on 17 meters, so I switched to 20. Ralf, DK7AH in Munich was just finishing up a QSO and I called him. He was also very strong. He gave me a 579. He was running 500 watts with a 5 element yagi. “UR LOUD ES CLEAR,” he sent. We chatted for a few minutes and then I packed up for the return trip.

These beautiful fall days only last a short time. I’m trying to get out whenever I can.

Interest in Space has changed radically since Apollo ended in 1973 and the Shuttle Fleet has been retired. Advances in Science through NASA have continued since then, but mostly from Low Earth Orbit, leaving only interplanetary probes and landers to perform the state-of-the-art observations at the great distances to the planets.

Space communications are enjoyed by all Radio Operators’ with the rewards of exacting views of Mars, all the way to Pluto and well beyond.

Human space travel beyond the Van Allen Belt stopped in 1973. Excursions to Lunar Soil…no more. Since its conception, NASA has drafted scores and volumes of plans for every conceivable mission possible from this planet. But only one plan stands out as most feasible in view of the pioneering spirit of offworld adventure… Going to MARS!

Dr. Robert Zubrin, of Pioneer Astronautics, Lakewood Colorado has a vision that extends to colonizing the planet Mars. His radical approach surpasses NASA’s studies in “micro-gravity” since 1973 and in his words “..the purpose of spaceships is to actually travel across space and go to new worlds, not to hang out in space and observe the effects of doing so….” (circa 2003, US Senate Committee of Space Exploration) His Book, “Case for Mars” lays out the most suitable approach of a Mars Direct (or, Semi-Direct) Plan of going there.

The Mars Society has established a number of MARS simulation stations on Earth called “Analog Stations.” Two of these, MDRS & FMARS are affordable platforms offering a “near-to experience” for future Martian dwellers,
in the traditions Dr. Robert Zubrin’s Mars Direct Program.

Since the first “Crew 1” of 2001, the Crews have displayed techniques for:

• Growing sustainable crops to survive
• Health & Medical care
• Habitability & Water Reclamation
• Geodesics and Photogrammetry
• UAVs & Rovers

…all this, with devices brought with them for the duration of their stay.

What they lack is a realistic communications system to simulate the kinds of remote communications they would actually use on the planet. This article is a call to Hams to solicit help for the Mars Society in establishing some meaningful amateur radio between and around the camps. This help can either be radio work-groups or donations towards current state-of-the-art equipment & devices.

Amateur Radio Has a lot to offer the Mars Society activities. If they adopt ham radio, then the licensing requirements would be mandatory for Crew Members and Mission Control.

HF Frequencies could be used for making reports to Mission Control in Colorado, New Mexico or, in relaying reports between the other Analogues Stations.

Getting their licenses reminds these operators the importance of their radio studies. It is a medium to use at all times, no matter which world they are on.

The objective is to have BOTH Analogs & Mission Control “permanently equipped” with Communications, PCs, Sensors & hardware.

1. Mission Control Radio Communication
   ( HF Med / High Power )
   For “checking in” and reporting status of accomodations.
2. Point-to-Point Communication
   ( VHF – Low Power )
   Mars has no ionosphere, therefore line-of-sight radio is handled by GMRS or 2 Meter Simplex Modes. Further Distance coverage is handled by a Remote, solar-powered, Repeater Station(s).
3. Telemetry
   ( VHF / UHF – Low Power using APRS ) for Weather, Seismic Sensor, Tracking, EVA Suit & Health, power charge monitoring.
4. Position Reporting
   ( VHF / UHF – Low Power using APRS)
   RDF, APRS and EPLRS Methods can be used because by the time man and women arrive on MARS, there will be a network of GPS-MARS satellites to support exploration. In addition Radio Direction Finding can be useful for Search & Rescue.
5. Ground Penetrating Radar GPR
   ( UHF – 1 to 4 watts for depth data – VHF for data transfer )
   Device mounted on Rover for high definition Tomography.
6. Satellite Communications
   OSCAR SATS [any or all available] ( VHF – 20 to 35 Watts )
   Remote Satellite Dish Controller and Program for Orbital Predictions. Exercising the practice of tracking and piloting a Supply Ship to and from the surface.
7. Power Management Monitoring
   ( VHF / UHF – Low Power )
   Solar / Thermal / RTG Power Plants and Storage Arrays.
8. Enhanced UAV
   ( VHF / UHF – Low Power)
   Ground Penetrating Radar.
   Geodesics – LIDAR and Photogrammetry.
   Seismic Sensor positioning.
9. Packet Digipeating
   ( VHF simulating MARS networks)
   Wireless internet – Multi-node – Global coverage.
   Telemetry,Telemetry, Telemetry….it’s about telemetry. The variety of existing APRS formats can be used to provide the neural life-blood of information that lives are depending on.

The objective is to use communications in a real-world environment to gain experience in day to day operations or emergencies 250 million miles away.

MARS simulated inhabitants would gain experience In the face of failures & power outages, and make immediate and command decisions as needed to conserve power in low power modes – alternate frequencies – troubleshoot – make on-the-fly Repairs.Similarly, MARS Ground Control would learn to activate alternate Tracking and communications Stations as needed to address every conceivable combination of situations no exceptions – as lives are on the line.

Communicating at such a remote and distant location, or in the protective cover of a Habitat or EVA Suit, is as important as the air they breathe.

The Mars Society’s Analog Stations of Hanksville, Utah, and Devon Island, Northern Canadian Reaches have been established over 15 years at locations almost identical to the Martian terrain, but with air. Well over 1,000 Crew Members have dedicated their studies of alternate foods, longevity, geology, mapping, power generation, tomography, astronomy, terraforming, fuel production…. …anything ….everything humanly devised, to be put to the task here and, out there.

Seen from their Crew Reports, there’s been limited use of telemetry, tracking and telecoms to date. University Teams who have introduced various hardware, have returned home with them and not left working systems behind to add to the stations. As such, the stations are relatively incomplete owing to the full spectrum of devices that are needed to make offworld procedures successful.

In the future, with Ham Radio participation and assistance in setting up communications, telemetry and networks, it is possible to see these Habitats fully equipped with more state-of-the art devices permanently on hand at all the Analogs and Mission Control Centers with real-time techniques and real-world equipment.

These Analogs and Simulatinos are not just practicing life on Mars for the sake of isolation. They are trying to replicate the full spectrum of conditions that would be involved in communicating with the distant world humans, and reporting their findings over these actual radio links. Using WiFi and the internet and our latest technology is not an accurate simulation. With Amateur Radio communications and links we would be practicing to be becoming proficient in the techniques involved in actually settling there.

This is a good opportunity for ham radio Elmers participate and consider what could be used on Mars and then help in setting it up (as well as get new experimenters, and scientists into the hobby).

Imagine how radio-quiet those first humans will find MARS to be. It will be like listening to the ether like Marconi first heard it on Earth a century ago, but without all the static and noise of lightning and thunderstorms. Maybe there are new noise sources on Mars or propagation possibilities as yet unexplored on Mars. Any ham radio made years ago still applies to the same Spectrum as devices do nowadays.

The radio communications needs are not just those on the surface of Mars but also every component that could very well be used: enroute to – orbiting above – onto, or under the Surface of Mars.

With the help of Hams, these Mars simulated stations on Earth can be much more than simple exercises in human isolation. The real-world experience with simple communications established from the ground up by the participants can be invaluable to learning about the experience of inhabiting a new world…

Think about this opportunity to involve Ham radio in not only the future of planetary exploration but also in involving these active and enthusiastic experimenters into a life long pursuit of the joy of radio communications.

Consider what you or your club can do to participate, or provide equipment donations that can be the instruments of success to this endeavor. The Mars Society is a nonprofit, and welcomes donations pertinent to their mission goals.

I hiked across Shute Hill this afternoon to David Swain’s Farm. The colors were stunning. I worked Bulgaria, the Cayman Islands, St. George Island, Aland Island, and Italy.

I started out at the old cemetery off the Rufus Colby Road and hiked south along a snowmobile trail. Along the way I took a snap shot of some of the trees.

It stayed in the 50s today, but was warm in the sun. I hiked about two and a half miles to the old range road and then into Swain’s field. I tossed my antenna wire into a gold maple and sat down in the grass with the KX3. Here’s a photo of the tree.

I operated on both 20 meters and 17 meters. Here’s my log:

11 Oct-16 1755 14.010 LZ3QE CW 559 589 Bulgaria
11 Oct-16 1758 18.072 ZF1DX CW 599 599 Cayman Islands
11 Oct-16 1800 18.074 K4G CW 599 599 St. George Island
11 Oct-16 1801 14.020 LZ1DS CW 449 599 Bulgaria

11 Oct-16 1810 14.024 OH0Z CW 599 599 Aland Island

The color is a few days away from peak. But we may not get another brilliant
day like today. I’m glad I got out.

The 630m band continues to provide interesting challenges for Canadian amateurs ... be they antenna, equipment or propagation related.




Sunday night produced another flurry of excitement on the new band, further demonstrating its potential for small stations operating from the suburbs.

On Sunday evening, VE3CIQ in Carleton Place, Ontario (southwest of Ottawa), and I, completed a two-way JT9 contact, following a short exchange of the required information (and more) just after midnight, Ontario time.

Noting the increased east-west favorability over the past few nights, Phil and I decided to give it a shot and were delighted to cover the 2200 mile / 3500km path while Murphy was sleeping and not messing with propagation.

Rather than randomly beacon on JT9, we both set 'calling each other' messages. Although this continued for some time, the QSO only took 12 minutes to complete once I started to decode Phil's signal out west. He had been decoding me and sending signal reports for a long time before his signal eventually peaked up here for the evening. I suspect that we could have continued the contact for the remainder of the night as his signal was getting stronger and stronger as we worked.

Screen shot of QSO from VE3CIQ's end

Following our QSO, Phil sent me some information about his station. His transmitter consists of a Yaesu FT-817 driving an XKA transverter which in turn drives his homebuilt class-E amplifier. The amp consists of three switching FETs in parallel, operating at 24V and produces about 175W out.

VE3CIQ - 630m Station

VE3CIQ - Homebrew 630m Class-E Transmitter

Phil's antenna is an 'inverted-L' style ... 45' up to the top of a Pine tree and then a very very long sloping top hat wire, folded back on itself three times, in a zig-zag pattern. This use of linear-loading allows him to squeeze a near full 1/4 wave antenna into his suburban lot as well as to reduce the size of his loading coil inductance. His ground system consists of ~3,000' of buried radials. By all accounts, it seems to perform very well as his WSPR beacon was recently heard in Hawaii!

VE3CIQ - 630m Linear-loaded Antenna

Phil's station stands as yet another fine example of those living in the suburbs without a lot of room for antennas yet still able to successfully operate and explore our new 630m band. With a little ham-radio creativity, it's surprising how well a small station can perform, especially when the propagation co-operates.


Following our contact, I moved back to the WSPR section of the band and continued beaconing overnight.


Apparently Phil and I picked a good evening to run a sked as the overnight WSPR map shows it to have been the best night of the new DX season so far, with forty-four individual stations reporting my signal via the WSPRnet website.

Interest and activity on 630m continues to grow nightly, now that the DX season has arrived and the reality of a 630m ham band for U.S. amateurs grows ever closer.

A great story sent by David Richer, WB6VGO about how amateurs helped rescue a sinking vessel in the Pacific.

Excellent work!

On September 28, 2016 at approximately 0300 UTC, Charles Houlihan, KD6SPJ, a net relay relay station for the Pacific Seafarer’s net while monitoring 14.300 received a call for assistance from the captain of the Sailing Vessel (SV) Rafiki. The captain reported that the SV Rafiki, a 35 foot sailing vessel, was taking on water. Charles who was the captain of the SV Jacaranda and located at sea, contacted Randy VanLeeuwen, KH6RC also a net relay and located in Hawaii. Randy contacted the US Coast Guard Station to report the incident and provide Rafiki’s location, 230 miles south of Cold Bay, Alaska.

Randy remained in constant radio contact with the Rafiki until contact with lost. Fred Moore W3ZU (Florida) and Peter Mott, ZL1PWM (New Zealand) additional net relays maintained contact with the captain of the Rafiki until the arrival of the Coast Guard the subsequent rescue.

According to a press release issued by the United States Coast Guard Station–17th District, a Coast Guard Air Station Kodiak MH-60 Jayhawk helicopter and an Air Station Kodiak HC-130 Hercules were dispatched to the Rafiki’s last reported position. Upon arrival the crew of the Jayhawk helicopter were successfully able to hoist the captain and one additional crew member to safety aboard the helicopter.around 1000 hours UTC. Both men were reported to be uninjured. The vessel was abandoned.

This real-life incident happened during the daily “roll-call” conducted by the amatuer radio operators (or “hams”) and members of the Pacific Seafarers Net. Everyday at 0300 UTC amateur radio operators from North America, Hawaii, New Zealand and Australia monitor the progress of maritime amateur radio operators who are sailing on the Pacific.

Prior to the start of the roll call for “maritime mobile” vessels, a call for medical, emergency or priority traffic is broadcasted. It was after such a call for any emergency traffic that the call for assistance from the Rafiki was received.

According the the net’s website (www.pacseanet.com): “The Pacific Seafarer’s Net is a network of volunteer Amateur Radio Operators that handles radio and internet email communication traffic between sailing and motoring vessels operating on all oceans and land-based parties. The land station Net Control Amateur Stations are located in various locations throughout the Continental United States, Hawaii, Australia and New Zealand. Communications traffic consists of daily position reporting and automatic posting of positions on several websites, message handling via email relays, Health and Welfare traffic, phone patch services, search and rescue coordination, and vessel equipment inventories for search and rescue operations. Life threatening emergencies are taken from any vessel whether or not they have ham radio licenses. Net control stations keep computer databases on participating vessels and their movements throughout the oceans.”

Here is this week’s space weather and geophysical report, issued 2016 Oct 10 0105 UTC.

Highlights of Solar and Geomagnetic Activity 03 – 09 October 2016

Solar activity was at very low levels with a few background flares observed from Regions 2598 (N14, L=174, class/area Dai/140 on 07 Oct), 2599 (S14, L=144, class/area Cko/460 on 05 Oct) and 2600 (N13, L=105, class/area Cso/110 on 09 Oct). On 08 Oct, between 08/1500-1700 UTC, a 10 degree long filament erupted in the NE quadrant centered near N38E40. A slow-moving, asymmetric, partial-halo CME was observed in LASCO C2 imagery, first visible at 09/0048 UTC.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during the entire summary period. A maximum of 32,138 pfu was observed at 03/1640 UTC.

Geomagnetic field activity was highlighted by mostly unsettled to active levels on 03-05 Oct. An isolated minor storm (G1-Minor) period was observed early on 04 Oct. Mostly quiet levels were observed from 04-09 Oct with isolated unsettled and active periods were observed early on 07 and 08 Oct, respectively. The enhanced geomagnetic activity was due to high speed winds from a recurrent positive polarity coronal hole. Some further enhancement occurred early on 04 Oct due to CME effects from an eruptive filament observed early on 01 Oct.

The solar wind environment began the period at about 500 km/s, increased to near 600 km/s midday on 04 Oct and slowly decreased to end the period at about 370 km/s. Total field generally ranged from 2-6 nT with a peak of 10 nt observed midday on 04 Oct. The Bz component was mostly variable between +/- 6 nT. Phi angle was in a general positive orientation throughout the period.

Forecast of Solar and Geomagnetic Activity 10 October – 05 November 2016

Solar activity is expected to be at very low levels with a chance for C-class flare activity 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 be at high levels on 10-11, 16-18, 24-26, 30-31 Oct and 01-06 Nov increasing to very high levels on 27-29 Oct. This is due to the anticipated influence of multiple, recurrent CH HSSs. Normal to moderate levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to be at unsettled to active levels on 11-18, 23-31 Oct and 01 Nov. G1 (Minor) field activity is possible on 13-15, 17 and 23-31 Oct with G2 (Moderate) levels possible on 24-26 Oct. This activity is due to the anticipated influence of multiple, recurrent CH HSSs. Additional enhancement to the field is expected on 13-14 Oct due to CME effects from the 08 Oct filament eruption. Generally quiet to unsettled conditions are expected for the remainder of the outlook period.
