I recently purchased a 2025 Ford F-150 truck that I am enjoying very much. I traded in my 2013 F-150 using all kinds of justifications but mostly I just wanted a new truck. That could be a story for another day. Of course, that brings up the need to install a ham radio in it. ... Read more

Parks On The Air (POTA) has exploded in popularity, with most of the activity on the HF bands. That makes sense — HF gives you the long-distance contacts and the big pileups. But don’t overlook the VHF bands, especially 2m FM. Two meter FM is simple, highly portable, and often an easy way to knock ... Read more

There I was, minding my own business at Field Day, when I ended up in a conversation with The Matts (KF0RIG and KG0AT). They said something about being in the Brass Knuckle Gang, which I knew nothing about. One of the Matts said “it is kind of fun and kind of dumb.” I thought “this ... Read more

In 2026, the ARRL is running a program to celebrate the 250th anniversary of the United States (America250). One part of this program is having designated hams activate W1AW (portable) in all 50 states. The operating is spread out over time, with a master schedule determining when each state will operate. W1AW/0 in Colorado Our ... Read more

In 2024, Joyce/K0JJW and I activated South Monarch Ridge (W0C/SP-058) on the Friday of the Colorado 14er & Mountaintop Event. South Monarch Ridge (also known as Monarch Crest) is a fun summit, easy to access via a trail or via the tram (during the summer). Kevin/KD0VHD and Lynaire/K0LPR joined us on top. Kevin took this ...

Here’s a post from way back in 2005. It falls into the category of “notable VHF contacts,” so I am reposting it here. Last July, my wife and I were walking along the beach on the eastern shore of Lake Michigan in Ludington State Park to the Big Sable Point Lighthouse. While we waited for ... Read more

When I talk about doing VHF SOTA activations, people often wonder about what kind of contacts to expect. VHF propagation from a mountaintop can be surprisingly good, and the range of possible contacts runs from the routine to the remarkable. Having done a lot of these activations, I’ve noticed that VHF SOTA contacts tend to fall into three broad categories. Let’s take a look at each one.

Type 1: The Local Contact (20–30 Miles)

This is the most common type of VHF SOTA contact, and it’s what keeps most activations from getting skunked. A simple 2-meter FM handheld radio, a decent half-wave antenna, and a summit with good Height Above Average Terrain (HAAT) — that’s all you need to make contacts with stations in the surrounding towns and valleys.

The typical range for this category is roughly 20 to 30 miles, with some variation depending on terrain. From most Colorado summits, this covers small mountain towns, outlying suburbs, or rural homesteads with a radio operator and a 2m FM rig. These are the chasers who have 146.52 MHz programmed in, monitor for activity, and are happy to give you a quick contact. Often, I’ll catch mobile stations driving through the high country with their radio set on 2m simplex.

These contacts are the bread and butter of VHF SOTA. Mostly reliable, repeatable, and very useful for getting the four QSOs to get the activator points. Don’t underestimate them.

Type 2: The Extended Contact (30–150 Miles)

Now it starts to get interesting. This category requires a bit more effort — both from the activator and the chaser. We’re talking higher power, a better antenna, or both. On the summit end, a 3-element Yagi like the Arrow II provides about 6 dB of gain over a half-wave antenna, which makes a significant difference. It also helps to run more power than a handheld radio can, with 25 watts making a big difference. A home station using 50 watts with a quality high-mounted omnidirectional or beam antenna can significantly boost range on the chaser side.

These contacts are mostly still on 2m FM, although SSB and other modes can really help at these ranges. The contact might require pointing the Yagi in the right direction, asking the chaser to try a different antenna orientation, or just working a little harder to pull the signal out of the noise. These contacts are made at the margin, so every decibel of signal strength matters.

This category represents a real challenge, and that’s part of the appeal. When you complete a contact at 100 miles with some rough terrain in the way, it feels like an accomplishment. You earned that one.

Type 3: The Exceptional Contact (150+ Miles)

These are the contacts that make you stop what you’re doing and say “wow.” Distances beyond 150 miles on 2m FM are not routine — they happen when something special is going on. Three factors drive most of these exceptional contacts:

Favorable geography. Two high summits separated by a long distance can sometimes “see” each other in a way that lower-elevation stations cannot. In the Colorado high country, summit-to-summit contacts across large distances are possible when both operators are at altitude. The geometry just works out.

Favorable propagation. This is where it gets really fun. Sometimes enhancement occurs on the VHF bands, which means the signals become significantly stronger. Several elements contribute to this, though most link to tropospheric conditions. Tropospheric ducting can have a very strong effect, occurring when atmospheric conditions create a temperature inversion that takes VHF signals well beyond normal range. The ionosphere can also play a role, with Sporadic-E propagation opening up the 2-meter band unexpectedly, providing path distances of over 800 miles. This is rare on 2 meters and more common on the 6-meter band.

Modulation type. FM is a great mode for local and medium-distance contacts, but it is not the most efficient modulation for squeezing out long-distance QSOs. SSB and CW require significantly less signal strength to complete a contact compared to FM — a difference that can easily be 10 dB or more. That’s a huge advantage when signals are marginal. So when the conditions are favorable but not quite strong enough for FM, switching to SSB or CW can make the difference between completing the contact and just hearing a ghost signal in the noise. This is one of the reasons I’ve been enjoying the 2026 SOTA Challenge on 2m and 70cm CW/SSB — it pushes operators to explore what’s really possible on these bands.

My best 2m FM contact from a SOTA summit is 245 miles (Mount Scott (W5O/WI-002)  — that one was a keeper. My best 2m SSB contact was 372 miles, from Three Mile Mountain (W0C/SP-107) to N0LL in Kansas. Longer contacts are possible, but you have to be on the right summit at the right time, with the right chaser listening.

Which Type Is Most Common?

Type 1 is by far the most frequent, and Type 2 contacts are a regular occurrence for activators who show up with the right gear and a good summit. Type 3 contacts are not predictable, but they are not as rare as you might think.

The key takeaway is that VHF SOTA is not a one-size-fits-all experience. You can tune your station and operating strategy to optimize for any of these categories, or just show up with a handheld and see what happens. Either approach can work, and both are fun.

That’s the universal purpose of amateur radio, after all.
