How well does 17 meters work?
I see a lot of people on 20 meters, but what about 17 meters? I take the sBitx v3 to Cloudland Canyon State Park (K-2169) for a little fun on 17 meters today… The combination of going to a park with your amateur radio gear and setting up an HF radio in a state park to activate as a POTA operator is a lot of fun.

What is the 17 meter band in ham radio?
The WARC (World Amateur Radio Conference) bands are nestled between the typical bands and everyone knows what they are because it is on the license tests. The ones I am referring to, in case you forgot for some reason, are 30 meters, 17 meters and 12 meters.
What the license test doesn’t teach though is that each band has unique characteristics that make it fun to use…at least that is how I see it. Since each of these WARC bands are stuffed between other typical ham bands, they seem to take on the characteristics of the two bands they sit between. Take 30 meters for instance, it will act like 40 meters with NVIS propagation on my hamstick to work hams just a couple hundred miles away and then I will work the west coast on the very next contact as if it were also a 20 meter contact.
Well, the higher the bands get the further they tend to reach more distant stations for me. I don’t have giant towers that have huge Yagi antennas on them for say 40 meters so my results are more of the typical ham who might have a dipole that is technically too low to the ground for textbook operation or a vertical with a couple of radials…you get the idea.
The 17 meter band has the same characteristics as 20 meters as well as 15 meters a lot of the time. For me the higher the band, the better the DX usually. I guess it has to do with the fact that the higher the frequency, the smaller the antenna and with a smaller antenna, the lower it can be to the ground and still have proper performance. Armed with this VERY basic knowledge of antenna theory, I usually expect some cool European stations on 15, 12 and 10 with the occasional DX on 17 meters, but today the sky was alive! Well, it would fade in and out and you can see it in my logbook reports. The signals reports over the time period of the activation go from 599 both ways to dismal 529 and 229 reports within an hour. This has been the norm as of late too, a lot of my activations lately have had events that would be described as cyclic in nature. I would hear a station call and reply to them with a 599 because they were booming in and then when I turn it over to them to reply, they will be a lot weaker and then you can literally hear them fade out while you watch and then fade back in by the time they turn it back over to me. It is really odd to hear that in real time for some reason.
17 meters covers a fairly small portion of band space as well with it only being from 18.068mhz to 18.168mhz. This is only 100khz of bandspace and yet there is room for a plethora of modes and operators. 18.100mhz is the watering hole for FT8 on the band and CW runs from the bottom of the band to about 18.090mhz for the most part. Voice operations will be above 18.100 usually and I have not made many contacts with SSB on 17 meters…
The POTA Activation on 17 meters
When I got to the spot I wanted to use for the activation, I was the only one there. So I setup in my usual spot and figured I would start on 17 meters to see how things were and if it wasn’t really happening, I could move down to 20 meters and get the activation easily there. I should have known things were going to be good when my first station of the day was VK3AWA!
Now you need to know something about me here. I thought this was a Canadian station since the call started with a “V”. I work so many Canadians that I have become accustomed to hearing the V callsigns and happily add them to the log. It wasn’t till I checked the QSO map that I realized that he was actually in Australia!!! They (it is an Australian club call) must have had a Yagi antenna pointed at me or something, along with a path opening as the signal reports were really good for a 12 watt transmitter running into a ham stick antenna on the back of a pickup truck. This contact was on FT8 and FT8 reads the signal strength in dB with the software to get the most accurate reading possible to send back. So it isn’t quite as subjective as something like CW where a lot of people (me included) will send signal reports based on how the op sounds to them and never reference a meter one time… So for my little radio to get a -8dB report from Australia had to have help from the atmosphere and probably a very good antenna on their end.
FT8 is a relatively new mode for me. I have normally not done anything other than the two original modes of CW and voice. For me to reach out into a new mode is a pretty big deal and this one works really well, which is why I like it. I am also looking to start messing around with PSK 31 some as well as possibly RTTY if I can figure out how to get the little radio to do it. I think PSK 31 will be pretty easy to master, so I will tackle it first.
What makes 17 meters so special?
The above map shows the performance you can normally expect from a band like 17 meters. Notice there is practically no contacts inside of about 600 miles other than two oddities here in Georgia? That is because of the antenna and the ability of 17 meters to have a pretty decent take off angle and also to reflect off the ionosphere easily. This garnered me a ton of contacts in the pacific northwest as well as the Atlantic north east and a scattering around the country to include Utah and southern California. Then there is the EU… I made several contacts with France and Germany today. That has been a little unusual lately for me and my system to be honest so I was stoked to see them in the log.
But this trip did something that I had not done before that I can remember… It netted 7 Canadian QSOs alone, combined with the other DX calls I technically activated today with only the DX contacts! That has to be a personal first.
I started with a DX call and finished with a DX call. How cool is that? It was a great day for radio and I really enjoyed using the sBitx with the new V3 firmware. The radio works so much better than the previous firmware and the FT8 is a breeze in the native radio setup. It you are into smaller radios and smaller companies and the idea of help from a collective of literal geniuses that willingly share their information with you, then this just might be a radio you will like. It is for me, I have had so much fun with it that it is hard to understand how I got along without it before…and the people over at HFSignals dont even know who I am…haha.

Hope you enjoyed this little diversion into the 17 meter band and inspires you to go out and setup your radio in a POTA park at some point!
