Sitting at your home station and tuning the bands is great fun, but the day you pack a small rig, a lightweight antenna and a battery into a backpack and head outdoors, you discover a whole new side of amateur radio. Parks on the Air, or POTA, is an international program that turns exactly that experience into a game and a community. In this post we'll look at how POTA works, the activation rules, how to pick portable gear, and practical tips that make life easier in the field.

What Is POTA and How Did It Start?
POTA is a volunteer-run program that encourages hams to operate from national parks, nature parks, protected areas and other registered sites. Each park has a reference code in the system. Operators transmitting from a park are called activators, while those who contact them from home or elsewhere are hunters.
The beauty of the program is that it offers something to both sides. Activators enjoy setting up a station outdoors with limited gear and handling pile-ups; hunters "collect" parks from the comfort of their shack. All logs, points and awards are kept on the official site, pota.app. Registration is free and you sign up with your callsign.
Turkey has a large number of national parks, nature parks and protected areas, so POTA holds real potential for Turkish operators, both for DX and for local activity. You can check which parks are registered, along with their reference numbers, on the map and park list at pota.app.
Activation Rules: The Basics
A few core rules decide whether an activation counts as "valid". Always read the latest detailed rules in the official documentation on pota.app, but the general framework looks like this:
- Be inside the park: Your station and antenna must be within the boundaries of the registered park.
- 10 QSOs in one UTC day: A valid activation needs at least 10 contacts within the same UTC day. You can still upload fewer; hunters get their credit, but the activation won't count as valid for you.
- Follow your license: The bands, modes and power limits of your license class apply. POTA grants no privileges beyond the regulations.
- Respect the park: Don't damage trees, don't block trails, ask park management if in doubt, and leave the site cleaner than you found it.
- Upload your log: After the activation, submit your log in ADIF format with the park reference included.
💡 Tip
Tip: An activation close to 00:00 UTC (03:00 Turkish time) can technically be split across two days because the date changes. Make sure your 10 QSOs land in the same UTC day.
Portable Gear: Light, Rugged, Simple
You don't need an expensive station for POTA. Many experienced activators say the best portable station is the one you actually take with you. The table below sums up two common approaches:
| Component | Lightweight (QRP) | Comfort setup |
|---|---|---|
| Radio | 5–10 W QRP HF rig | 100 W mobile/base HF rig |
| Power | Small LiFePO4 pack or internal battery | Larger-capacity LiFePO4 battery |
| Antenna | End-fed half-wave, telescopic vertical | Dipole, mast-mounted vertical with radials |
| Support | Telescopic fiberglass pole, tree branch | Tripod, vehicle mast mount |
| Logging | Paper notebook or phone app | Laptop with logging software |
Choosing an antenna
In portable work the antenna matters far more than transmitter power. A well-deployed resonant antenna will often beat a poorly installed high-power station. Popular choices include:
- End-fed half-wave (EFHW): Fed from one end, easy to hang from a tree or a fiberglass pole, and usable on several bands with a suitable matching transformer.
- Linked dipole: An efficient, tuner-free option where you open or close jumpers to change bands.
- Vertical with radials: Gives a low radiation angle that's great for DX; a few radial wires laid on the ground noticeably improve efficiency.
Before heading out, set the antenna up at home or in the garden and measure its SWR. If something goes wrong in the field, you'll have a reference to compare against. If you're curious about SWR, check out our SWR article on the site.
Power source
LiFePO4 batteries are the favorite power source for portable operating these days. They're light, their voltage stays fairly flat during discharge, and they survive many charge cycles. When choosing one, consider the current your radio draws on transmit and how long you plan to operate, and don't skip properly sized wiring and a fuse.
Operating in the Field: Spotting, Calling and Logging
You've reached the park, put up the antenna and switched on the radio. Now the hunters need to find you. The most effective way is to self-spot: post your callsign, park reference, frequency and mode on pota.app, and hunters all over the world will see you. Without mobile data, some activators rely on automatic spotting such as the Reverse Beacon Network (RBN) for CW and digital modes.
A smooth field session can go like this:
- Find a clear frequency consistent with the band plan and listen for a while to make sure it's free.
- Ask if the frequency is in use, then spot yourself.
- Mention the park in your call, for example on SSB: "CQ POTA, CQ POTA, this is TA4XXX, park TA-XXXX".
- Keep contacts short: callsign, report and, if applicable, the hunter's own park (park-to-park).
- Log each contact immediately, including UTC time, band and mode.
Park-to-Park (P2P) contacts are a special treat: when you work an activator in another park, both of you earn credit as activator and hunter. Remember to log the other station's park reference too.
Picking a mode
SSB is the easiest place to start, and running a pile-up is a social experience in itself. CW goes remarkably far even at low power and is the QRP activator's favorite. Digital modes such as FT8 can make contacts in poor conditions, but each QSO takes longer, so reaching 10 contacts may take a while. Whatever you choose, stay within the bands and modes your license allows.
Safety and Etiquette
Operating outdoors is exciting, but a few things deserve attention:
- Weather: Never put up an antenna during a thunderstorm, and end the activation immediately if one approaches. Lightning is the biggest hazard for portable stations.
- Other visitors: Route antennas and cables so nobody trips over them. Curious passers-by are a perfect chance to promote the hobby.
- Permissions: Some protected areas have special rules. When in doubt, ask park management.
- Leave no trace: Pack out your rubbish and don't leave stakes or bits of rope behind.
- Tell someone: If you're heading somewhere remote, let someone know where you'll be and when you expect to return.
Starting Out as a Hunter
If you're not ready to head into the field yet, hunting is a great way to get started. Follow the live spot list on pota.app, call active parks and upload your log. You'll learn the rules, the calling style and the dynamics of a pile-up along the way. As you work more parks you earn awards and badges, which adds a nice bit of motivation.
Hunting is also a good test of your own station: if you can copy a QRP activator, your receiver and antenna are in good shape.
Summary
POTA takes amateur radio out of the shack, blends nature with technology, and appeals to everyone from newcomers to seasoned DXers. The essentials: stay inside the park boundary, aim for 10 QSOs in one UTC day, spot yourself, upload your log, and leave the park as you found it. With a light rig, a good antenna and a charged battery, your first activation will be easier than you think.
