Tips for Operating the FT8 Digital Mode

The FT8 mode is taking ham radio by storm, and for good reason. Just as we were becoming despondent about entering the doldrums of the sunspot cycle, here comes a mode that can dig signals out of the noise and copy them Q5. The high bands, particularly 15, 12, 10, and 6 meters are suddenly capable of producing DX QSO's with regularity. It's miraculous.

I have been using the mode with great success to work new band countries for the DXCC Challenge award. In the process I have learned a few lessons. While the mode is actually pretty easy to master, there are a few things to pay attention to.

1. Maintain Accurate Timing. The shack computer cannot be more than a few seconds off official UTC, or this mode simply won't work. Its weak signal performance depends on perfectly timed transmission and reception sequences. My Windows 10 computer was set by default to automatically sync the time every week and that turned out not to be good enough. I have now got it syncing frequently, which solved my problem. To check your computer's accuracy bring up the clock in the lower right corner of the screen and watch it while listening to WWV. The long beep from WWV should occur exactly on the minute. Another way to check is to bring up the https://time.is web page, which will automatically display your time discrepancy.  See below for instructions on how to force your windows computer to time sync. The solution I recommend is called meinberg ntp.

2. Don't use a narrow filter. If you can control the filter bandwidth, open it up to 2.8 KHz or greater (except 60m, which is a special case). Also, if you are using SSB mode, make sure you don't have an equalizer turned on. My K3 has a digital mode that bypasses the equalizer and has its own mic input level setting. Check you manual to see if you have a similar setup to use instead of using the SSB mode.

3. Make sure your computer mic is off and gain is set correctly. I occasionally hear folks transmitting an FT8 and their mic is also on. That can be embarrassing! Watch your ALC and keep it below the threshold which is typically one bar (note that the Elecraft threshold is five bars) and by all means make sure you don't over drive the input and trash the frequency. Keep the power level down, too, to ensure a clean signal and a cool running final. Half of rated power, max, is a good rule of thumb. Remember, FT8 is a weak signal mode. There's no need to dominate the frequency with high power.

4. Read the excellent manual and watch some YouTube videos before you try to make contacts.Work a few stations before you try calling CQ. Here's a link to an excellent operating guide -- FT8 Operating Tips

5 If you need a USB interface to connect the computer audio out/in to the transceiver audio in/out, consider a Tigertronics SignalLink, MFJ 1204 or the RigBlaster plug and play control interface. I have also had success just using a Griffin iMic USB sound card dongle with a line input (most sound card dongles just have a mic input which is easily overloaded by the line level audio output of the rig). Just plug the dongle into a usb port, change your computer sound settings to default to the dongle, plug rig audio out into the dongle line input and plug the dongle output into the rig input. Adjust the settings to prevent overloading these circuits, and go.

6. If you are a DXer like me, learn to operate split using the waterfall display. FT8 doesn't handle simplex pileups better than any other mode. Uncheck the TX=RX box. Double click on the DX station callsign you want to work, then shift click on an open frequency on the waterfall display. Practice this technique when answering ordinary CQ's.

7. For more tips and shortcuts, go to the FT8 main screen and press F3 or F5.  Download WSJT-X here:  Clicky

8. While FT8 is semi-automatic, you can send messages manually by  un-checking the auto sequence box and clicking the TX numbered boxes. You can also double click TX1 to prevent it from automatically sending and put a contest exchange in TX5.

That's about it. This mode is easy and fun to use, especially for quick DX QSO's and weak signal work. It's fast, too. QSO's only take about a minute. It is bound to make its way into the SOTA world as soon as a lightweight external processor or phone app is developed.

Time Sync instructions

Meinberg NTP is the best solution I have found for time syncing in Windows. It is a free binary app without a windows interface that runs in the background as a "low overhead" service and calibrates my computer time as frequently as necessary to keep it exact. I have had it running for quite a while now and it has worked perfectly. Download here Meinberg NTP. If you want to customize monitor, or control Meinberg NTP learn more here MeinbergMonGuide.pdf

There are several other reasonably good options. Here are the instructions for setting up your windows computer for hourly time sync. The is also an app available called Dimension 4 if you aren't comfortable following these instructions or prefer a windows interface.

Make Windows synchronize time more often This page explains how to make the Windows network time (NTP) client synchronize its time more often than the default once per week. This was tested on Windows 7 but should work with Windows XP and above. Why is this important? I don't know about your machines but both my desktop and my HTPC have terrible clocks. They seem to drift by about five minutes each week and that messes up things like scheduled TV recordings or stating that it is 13:37 o'clock o...

10 Essentials for Hiking in Colorado -- High Altitude Mountaineering Tips

Alferd Packer

I live part time in Buena Vista, Colorado, at 8,000 feet in the heart of the Rocky Mountains. Over the years, I have hosted quite a few visitors who want to experience the high country, or even try a 14er ascent and I have successfully guided quite a few group ascents.  Since 2013, I have climbed over 300 summits as a participant in the SOTA program.What I have learned from this experience and from taking the High Altitude Mountaineering Course at the Colorado Mountain Club is that the Colorado high country is like being on "another planet", with its own set of rules. Common sense rules we've learned at sea level don't apply here and, in fact, can put you in danger. Skeptical? Check out Alferd Packer (click the link). You don't want to end up like the Donner party! Or, for a more recent update, checkout the September 17, 2017 headline of the Denver Post - 11 Deaths This Summer.

I can remember my first 14er ascent in the summer of 1973 of Longs Peak, shortly after moving to Colorado from Illinois. I wore shorts, a tee shirt and carried a pint of water. For the 16 mile round trip, I started at about 7 am. When I finally made it back to the car at 8pm, I was dehydrated and suffering from hypothermia. Quite a powerful and memorable introduction to high altitude mountaineering! Fortunately, I was young and prepared to learn lessons the hard way.  That's not the case now.

The purpose of this post is to provide some basic guidance and encouragement to activators who want to visit Colorado and enjoy the back country without the sort of mishaps that rookies often encounter. By applying these rules, starting modestly, and gaining some experience, there;s no reason why your hard earned SOTA skills can't be applied in this "alien" world. 

1. Extra Layers

 As you ascend, the temperature drops about 3 degrees for every 1k feet of elevation gain. If you start in Denver and drive 1 hour west to Bierstadt and hike up, you can expect the temperature to drop 40 degrees (or more). Tourists don't get it. It is amusing to visit Pikes Peak and see tourists in shorts and tee shirts shivering their butts off in 40 degree howling wind and flurries after driving up from Colorado Springs where it's a balmy, sunny 80 degrees. I hike in a poly tee shirt, a long sleeve shirt (or turtle neck, depending on the season), a puff vest, and a shell (with under arm vents). Wind can be fierce, especially above timber line, so a shell is essential to keep out wind and moisture. My pants are poly, and my hiking boots are gore tex. In the winter, I often add an extra layer. Avoid cotton, which retains moisture. Remember, there is no such thing as bad weather, only poor clothing choices.

2. Start Early

Horseshoe Mountain, Mosquito Range, Colorado at Dawn, 13,905'

The mountains create their own weather. In the summer, the pattern generally starts with a perfectly clear sky with clouds building up gradually as the day progresses. Thunderstorms with lightning typically occur in the early afternoon, after 1pm or so. It's a good idea to be back to timberline by 1pm. After my youthful Long's Peak debacle, my next summit of that peak included an overnight above timber line. When I woke up at 5am for my final ascent, I saw headlamps coming over the ridge. The experienced in and out hikers had started their trip at 3am and chosen a full moon to do it. I now consider dawn to be the latest time to start a 14er ascent. Earlier if the approach is a long one. Hit the trail at the break of dawn.

3. Food and Water

Water is heavy and it is tempting to skimp on it, but that can be a big mistake. You want to stay hydrated to keep your body and mind functioning well, and you want some extra water, in case things go wrong. As a general rule I recommend a minimum of one liter for every four miles, but more is better if you can handle the weight. I recommend the Platypus bladder system. I also carry extra water in the truck and drink a liter before I hit the trail - and it's there if I run out on the way back.  Throw some food in the pack. I carry a few extra energy bars and a sandwich. It's OK if you don't eat them. But, you may need them. It's not good to hit the wall for lack of food or water. Colorado has low humidity. This dryness which increases with elevation sucks water from the body. Avoiding dehydration at high altitudes requires regular hydration. Don't wait until you are thirsty - that's too late. Hydrate at regular intervals. The first thing to think about if you feel dizzy or have a headache is dehydration. 

4. Personal Locator Beacons, 2 Meter Radios,  and APRS

Thinking about some worst case scenarios, I began carrying a PLB. I hike alone about 90% of the time. Much of that time I am bushwhacking in remote areas with no cell coverage and low likelihood of encountering another person. If I am injured and cannot walk out, I need a way to let people know where I am. This 4.3 ounce PLB takes care of that. I also carry a VHF/UHF hand held ham radio. Colorado has great APRS and repeater coverage, so I can spot myself using APRS, or use it to message my status back home. I can even let SOTA chasers follow me up the mountain just by turning of the location beaconing as I ascend. I often grab a few VHF contacts on 146.52 at the end of an activation. With these two lightweight devices, I can call for help if I need it, or communicate with family and friends when I am out of cell coverage. Be prepared to communicate in the event of an emergency and no cell coverage. If you are in the backcountry and don't have a ham license and carry a handheld 2 meter radio, you are missing out on a fantastic free public safety system. The same system that Amateur Radio Emergency Services use. 

5. Map and Compass

When I started out, that literally meant a map and compass. Today, for me, it means my iPhone, Gaia app, and Google Maps app. Todays cell phones have built in GPS receivers and, with a little planning, they work fine in areas with no cell coverage. I simply download a coverage map to my phone from Gaia and Google Maps in advance of my trip. Learn to read topo lines and follow them and learn your hiking speeds (up and down) so you can estimate travel times accurately.  Prior to a hike I derive a parking spot from Google Earth and lay down a waypoint in Gaia. I use the Gaia coordinates as a driving destination in GMaps. Most of the pre-trip planning I do is consumed by determining where to park and begin the trek. In Colorado, it's also important to descend the same way you came up. After an activation, in a rush to get down, it's easy to pick the wrong descent line and find yourself stuck in a ravine. Many Colorado search and rescue operations can be traced back to a hiker taking a "short cut" whether intentional or unintentional on the descent. Don't just "fall off" the mountain, follow the proper descent line. The easiest way to do this is to record the ascent and follow the same line of the descent. One other tip. I also wear a compass watch and take a bearing on the summit at the start of a hike. If all else fails, I can follow that bearing down. I also mark the car with a waypoint before ascending (I learned that lesson the hard way.) Don't lose your way.

6. Flashlight and backup phone/gps battery

I know you don't "plan" to hike in the dark. But if you find yourself in the backcountry after dark without a flashlight, it's not fun - it's dangerous. I carry a "lipstick" backup battery for my iPhone, that also serves as a flashlight.  If you are going to rely upon a smartphone for navigation, as I do, you must carry a backup battery. Don't get caught without power and light.

7. Strike Ignitor

Not only does the temperature drop with elevation, it also drops 30-40 degrees when the sun goes down.  In the event of an unplanned over night stay in the wilderness, this will allow you to stay warm and survive until morning.    Be prepared to start a fire.

8. Sun Protection

At higher altitudes, a thinner atmosphere filters less UV radiation. With every 1000 metres increase in altitude, UV levels increase by 10% to 12%. Unprotected skin at high altitudes burns fast. That's the primary reason why Colorado has the highest incidence of skin cancer in the country. Precancerous actinic keratosis is extremely common here. Many Coloradans visit a dermatologist each year for a check up and come home with arm, leg, face or scalp bandages from AK removal. You really have two choices, slather your skin with sun block or cover your skin with long pants, long sleeves shirt, and a wide brim hat to protect your scalp, neck, ears and nose (a ball cap won't cut it). I prefer the latter, with some clear zinc oxide sunblock on my nose and ears. Protect your skin.

9. Medication

The most common medical problems I have encountered on high altitude hikes are foot blisters, altitude sickness, and aches. Foot blisters are generally the result of poor footwear choices, bad fit, or inadequate break-in time. All of these can and should be identified and corrected prior to hitting the trail just by wearing the footwear for a week or so at home and taking some long walks. Carry some moleskin. Don't underestimate the misery you can inflict on yourself by failing to heed this advice!

The air is much thinner up here and it takes some getting used to.  Fewer than ten percent of people visiting Denver get altitude sickness. That jumps to 35% when once you get up around 10,000 feet and increases with elevation. The most common symptoms are dizziness, nausea, headache, loss of appetite, and insomnia. I've observed it first hand on several occasions, and it's alarming. Altitude sickness can often, but not always, be avoided by spending more time acclimating in Denver before heading up to higher altitudes. There is a lot of randomness associated with this reaction. Just because you get sick once, doesn't mean you will the next time, and just because you've never been sick doesn't mean you won't be in the future. So, it's best to be prepared. Ibuprofen has been shown to be an effective treatment, and it also has the benefit of treating the aches and pains that often accompany strenuous hikes. Taking ibuprofen before hand is probably a good idea. For more severe symptoms or as a prophylactic,  doctors often prescribe Diamox (or another similar drug). If you won't be spending a few days acclimating, it's good to have some Diamox handy, just in case. Just call your Doctor and let her know your plans and concerns and fill the prescription before your departure. Diamox is not an over the counter drug.

10. Trail Etiquette

Most regular Colorado hikers know and observe trail etiquette. You should, too. Here are some key aspects of good trail etiquette:

• Uphill hikers have the right of way. Stand aside for uphill hikers so that they can maintain their  rhythm and momentum.
• Leave no trace. Don't discard anything. Pick up trash if you see it. 
• If there is a maintained trail, don't hike off trail, especially above timberline. Erosion is a problem with all trails. Maintenance is expensive and time consuming, so respect the mountain by staying on trail. Above timberline, the alpine tundra is very fragile. I can't stress this too much. Researchers estimate that Colorado alpine tundra already damaged by human activity will require hundreds of years to fully recover. 
• Make eye contact with passing hikers, be friendly, and say Hi. That's the Colorado way!
• If you are setting up a SOTA station at the summit, position it so that it doesn't interfere with other hikers and be ready to demonstrate and explain what's happening.
