Yesterday I dabbled in the OK/OM DX CW contest for about an hour and a half. This time for some fun and interest I entered QRP level but lowered my power to just one watt. Propagation has been surprisingly nice over the past week or so and I wanted to give the new solar flux a test run. My radio is the Icom 7610 and my antenna is a slopped Endfed antenna at about 25 feet. I stayed on 20m as the radio gods seemed to be smiling on me there. I made only 10 contacts as I was not in the contest for scoring just to see how the fishing was with one watt. I was only asked for repeats regarding my exchange twice other than that the 1 watt made it through. 

Because I was operating at only 1 watt I also wanted to take the loss of my SWR into account. I checked with my antenna analyzer and the CW portion on 20m my SWR was 2.3:1. According to the power loss at various SWR readings chart at 2.3:1, I was in around 15% so this took my 1 watt down to 850 milliwatts. 

Below are the results of my QRPp contest efforts: 

Band     20m 

QSO     10

Score    300

Contacts and Miles per watt using grid square to grid square for millage  

1. OM7M        3720 miles  4376 miles per watt at .850 watts. 

2. OM3CGN    3795 miles 4464 miles per watt at .850 watts.

4.OK7K          3503 miles 4121 miles per watt at .850 watts.          

5. OK1DOL    3478 miles 4091 miles per watt at .850 watts.

Back in May I posted regarding an RFI issue I was having and at the time I thought is was the neighbors heat pump. A few weeks ago my neighbor was away on business and his heat pump was off but my RFI was still present and more of it! I took my Eaton FRX5-BT put it on AM with the antenna up and took it for a walk about. When I passed by my Hydro smart meter the RFI was present big time but last time there was no issue at the meter. Upon investigation I read that the meter has cycles were it transmits data and thus the off and on issue with the RFI. The other issue is we are in very close proximity to other homes and I am certain my Endfed antenna is picking up not just my smart meter. The good new in all this is my Icom 7610 has great filtering and my NB is able to filter it out and the issues are gone. It's a problem that I can live with along side the rigs filtering.

Recently, I gave a presentation to the ARROW radio club in Ann Arbor, MI on the topic of “Having Fun With VHF”. I’ve given this talk several times now, highlighting some of the topics in my book, VHF, Summits and More: Having Fun With Ham Radio. When I discussed my Summits On The Air (SOTA) activities, Thom/W8TAM mentioned that Parks On The Air (POTA) was probably a better fit for Michigan. (There are SOTA summits in Michigan but most of them are in the upper peninsula or the northern part of the lower peninsula.) This got me thinking about POTA and I followed up with Thom via email a few days later to get a bit more information.

Being a fan of the US National Parks, I had done a few activations during the ARRL National Parks On The Air event in 2016. (Holy decibels, was that really 4 years ago?) The POTA program is similar but is an ongoing program, kind of like SOTA.

What’s A Park?

I am not sure of the specific criteria for parks to be included in POTA, but it seems to be pretty much National Parks (including National Forests) and State Parks. The POTA website talks about these typical categories of POTA stations: backpack, picnic table, campground and Field Day.  Backpack looks very much like a typical SOTA activation, a small portable station carried by humans (or maybe goats) to the activation site. Picnic Table is a little bit different, with more gear and less hiking. Campground and Field Day take advantage of operating close to or inside a vehicle.

I see quite a bit of overlap with other activities that I like: SOTA, hiking, camping, parks and travel.

Colorado

To get a handle on local opportunities, I looked at the 85 POTA parks listed for Colorado. (Compare this to over 1805 SOTA summits in the state.) These are National Parks, National Monuments, National Wildlife Refuges, National Recreation Areas, National Grasslands, National Scenic Trails, National Historic Trails, National Forests,  and Colorado State Parks.  In short, POTA includes the National Park System, National Forests, and State Parks. Cool!

We see a similar picture in Kansas, which has zero SOTA summits. (Sorry, it’s just too flat.)

SOTA activation opportunities are obviously skewed toward mountainous areas. Islands On The Air (IOTA) is generally near large bodies of water. However, POTA is available everywhere. Americans like parks and we have lots of them.

First impressions

I have been heavy into SOTA, so that’s the perspective I have when checking out POTA. POTA requires 10 QSOs to obtain points for an activation, while SOTA requires only four. SOTA activations must not be in, or in the close vicinity of a motor vehicle, cannot use a permanent electrical power source, nor use a fossil fuel generator.  Also, no part of the station may be connected in any way
with the motor vehicle. All equipment must be operated from portable power source (batteries, solar cells, etc). The POTA rules don’t have these restrictions.

The SOTA points system and logging database are pretty much on the honor system. Send in a log (Activator or Chaser) and you’ll get credit for the points you claim. POTA only collects logs from the Activators. So if you are a Chaser (Hunter, in POTA terminology), you don’t submit a log and your points are dependent on the Activator getting a log submitted. POTA log submission is via email and may take up to two weeks to get processed, while SOTA is instantaneous.

What’s Next

I have not quite figured out how I will participate in POTA. For starters, it can be a nice overlap with SOTA. Most of the SOTA summits we activate are on National Forest land, so they also count as POTA activations. Lately, Joyce/K0JJW and I have been RV camping in state parks, so that sets us up for an easy POTA activation. We are also working on visiting all of the US National Parks. POTA probably isn’t a great match for VHF operating, unless it has some Height Above Average Terrain.

I can appreciate the accessibility of the POTA program. It does not require a lot of physical ability to do an activation. The flexible rules allow hams to set up a station in a variety of ways and it seems most hams have a park nearby they can activate.
