Heavy RFI in Mesa

Radio Frequency Interference, or RFI, is a well-known and much documented problem. RFI hopefully is less common and disruptive than in the old days of amateur radio. Modern amateur radio equipment stays more tightly on frequency and is easier to tune. Modern television and radios are superior to the old ones at discriminating unwanted signal and receiving the desired stations. Why, then, an article now about RFI in Mesa?

We have discovered a pervasive source of RFI in TowerPoint Community in Mesa. The effect seems very strong and widespread throughout this community of over 1,000 people. We wonder it hasn’t been reported, but our research shows no notices on the RFI from in or near this Resort.

N4RTG Debbie and N5RTG Jim have been here eight days. These eight days have seen no (absolutely ZERO) participation by either of us on the regional or national ham radio nets. The week before we arrived to TowerPoint we were daily checking in on the 20 meter RV Service Nets (networks of home-based and mobile ham radio operators checking in and reporting on location, weather, health, and travel plans) out of Minnesota and Tennessee, and the 40 meter Pacific RV Service Nets from Longview, Washington and points in California. We cannot get on the nets due to the interference.

We were able, after just a little consideration and without any fox-hunting, to locate the source of the radio frequency interference. The answer should not have surprised us. Our good friend, W7IRY Bob, warned us of the likely interference problem before we arrived. Some things don’t go away even if you ignore them.

We have spent time, every morning and afternoon, at the TowerPoint Tennis Club. Our morning starts there before breakfast at 0700 hours when we hit for part of an hour before the Club activities consume all the courts. After breakfast we return to the courts to watch competition or team practices.

Monday (yesterday) we spent from 0645 hours until almost 1300 hours (over six hours) playing and watching. It was Jim’s first competition in two decades. He was paired with John H, a classy and very experienced player. They were facing a dynamic duo from a neighboring Resort and, the word was, the duo were undefeated last year. At least Jim would have some good experience from the match, even with the loss.

Jim and John played great together and hit a lot of good shots. Their very worthy opponents lost despite their good play and great chip lobs. Jim and John are looking forward to another match next week and many more over the next winters here. After their match, they grabbed some snacks from the Club kitchen and we watched the remainder of the Men’s and Women’s 3.5 League matches (our team won 12-5 against ViewPoint Resort).

Jim walked back to the courts yesterday late and watched another of the Resort’s teams practicing. He helped shag balls for the team captain and instructor so they could spend more time coaching. We are parked so close to the courts it is hard not to wander over and pick up a game or just watch.

This is a great tennis community with wonderful facilities and people. We’re enjoying more tennis at TowerPoint than we’ve had in many years. Which brings us back to the radio frequency interference.

Our ham radios are mobile, which means they are in our truck and rolling home. We can’t operate HF to reach the regional and national RV Service radio Nets from the tennis courts. Even if we could, we shouldn’t. All this great tennis is interfering considerably and frequently with our ham radio receiving and transmitting. If this isn’t a clear case of radio frequency interference, I’ll eat my hat with the callsign on it.

W7IRY calls the effect “the great sucking sound” of an activity pulling someone in completely. We were duly warned and have no one to blame. Nor would we. We’re having a great time, meeting lots of wonderful people, and getting much more physical activity than we might otherwise have taken. Thanks to the TowerPoint Tennis Club!

  1. Are you guys in hibernation? What’s up?

    Inquiring minds stuck in an office while looking at snowflakes fly around outside want to know!!!

    God bless.

  2. Ah the power of a google search! And an observation from the lower ranks of the TowerPoint tennis group, Jim and Debbie’s affection for the club here is fully reciprocated, as there were multiple efforts threatened to de-wheel their rig and thereby prevent their departure. But alas, the best we could do was to extract a promise of their return for next season. As recent converts ourselves, Marty took up tennis again after maybe 40+ years, a statistic that becomes all the more frightening once one sees it here, in text. TowerPoint Tennis, where RFI stands for Really Friendly Interests! Travel well, Jim & Debbie, see you next season.
