Can Technician Class Hams Work Satellites?

One of the most common questions from newly licensed Technician class operators is whether they can work amateur radio satellites. The answer is a clear yes — Technician privileges cover all the frequencies used by FM and most SSB amateur satellites. Working satellites is one of the most exciting things you can do with a Technician licence, and it requires less equipment than most people expect.

Technician Privileges and Satellite Frequencies

Technician class licensees in the US have full privileges on VHF and UHF — the frequency ranges used by virtually all amateur radio satellites. The FCC rules are explicit: any amateur holding a Technician class or higher licence may communicate through amateur satellites on the satellite's uplink frequency, provided they're licensed for that frequency.

The most popular FM satellites use:

• 2 metres (144–148 MHz) — Technician full privileges ✓
• 70 cm (420–450 MHz) — Technician full privileges ✓

This covers SO-50, AO-91, the ISS, and most of the active FM satellite fleet. You're fully licensed to use all of them from day one of your Technician ticket.

For SSB satellites like FO-29 and RS-44 that also operate in the 2m and 70cm bands, your Technician privileges apply equally. AO-7 Mode B uses the 10-metre band for its downlink — Technician licensees can receive on 10m (listen-only is always permitted), though transmitting on HF requires General or higher.

Why Satellites Are Perfect for New Technician Operators

Local repeater work is how most new hams start, and there's nothing wrong with that. But satellites offer something different — and in some ways more accessible:

No repeater trustee required. You don't need permission, a club membership, or a local infrastructure to get started. The satellites are up there, they're free to use, and they work anywhere you have a clear sky.

Passes are completely predictable. Unlike HF propagation which varies with solar conditions, satellite passes are mathematically precise. If the predictor says SO-50 will be at 45° elevation at 14:23 UTC, it will be. You can plan your operating session days in advance with complete confidence.

Contacts across vast distances. A satellite at 400–800 km altitude has a footprint covering roughly 3,000–5,000 km in diameter. A contact through SO-50 can span entire continents with a 5-watt HT. For a Technician licence holder accustomed to local VHF/UHF range, this is remarkable.

The learning curve is real but fast. There are things to learn — Doppler shift, pass timing, antenna pointing, split frequencies. But you can learn all of it in one or two passes. By your third attempt you'll be operating comfortably.

Your First Satellite Contact — Step by Step

Step 1 — Find a Pass

Open Ham Sat Tracker on your phone. Enter your grid square (e.g. FN25 for Ottawa, EM72 for Nashville, DM33 for Phoenix) and tap Calculate. You'll see upcoming passes for SO-50, AO-91, ISS, and other satellites with pass times and maximum elevation.

For your first attempt, choose a SO-50 or AO-91 pass with maximum elevation above 30°. Higher elevation = stronger signal = more forgiving for a first attempt.

Step 2 — Programme Your Radio

For SO-50: set VFO-A to 436.795 MHz (receive/downlink) and VFO-B to 145.850 MHz with 67.0 Hz CTCSS (transmit/uplink). Enable split operation. For AO-91: 435.250 MHz receive, 145.960 MHz transmit, no tone.

Use the Doppler-corrected AOS frequency from Ham Sat Tracker as your starting downlink frequency rather than the nominal value — you'll be closer to the satellite's actual received frequency from the moment it rises.

Step 3 — Get Ready Before AOS

Know the AOS azimuth from the sky view diagram and be facing that direction before the satellite rises. Have your antenna at a low elevation angle (10–15°). Being ready at AOS gives you the full pass rather than scrambling to find the satellite after it's already up.

Step 4 — Listen First

When the satellite rises you'll hear a squelch tail, other stations calling, or the satellite's own audio characteristics. This confirms it's working and in range. On SO-50 you may need to activate the on-timer with a brief 74.4 Hz tone burst if no one else has used it recently.

Step 5 — Make a Call

Keep it short: "This is [callsign], [grid square], listening." If someone comes back, give a signal report (59 or 57 etc.), get one back, say 73 and clear. The whole QSO might take 30 seconds — that's normal for satellite work.

Step 6 — Track the Doppler

As the pass progresses, tune the downlink slowly downward from the AOS value toward the LOS value shown in Ham Sat Tracker. For FM satellites this is a gradual sweep of a few kHz over the pass duration. You'll notice the audio sounds clearest when you're on the right frequency.

What If You Don't Make a Contact?

It happens, especially on your first few passes. Common reasons:

• CTCSS tone not enabled on SO-50 — double check this one
• AO-91 was in eclipse — try a daytime pass
• No other stations active during that pass — try again at a busier time
• Antenna not pointed correctly — the sky view diagram in Ham Sat Tracker helps with this
• Low-elevation pass with obstructions — choose a higher pass next time

Even a pass where you don't make a QSO is valuable. Listening to the satellite, hearing the Doppler shift, watching the signal strengthen and fade — all of that is learning that pays off on the next pass.

Your Technician licence is a full ticket to one of the most engaging corners of amateur radio. The satellites are waiting. 73 de VE3AKK
