Today I finally got the answer to my complaint of pool pump RFI from
Fluidra, a national distributor for the Jandy Pool Pump next door. As
expected, they assume no responsibility because of their claim that
their product (a multispeed motor) "meets all codes and regulations
required as well as those of the FCC." This issue prompted my post on
Sept 2: RFI- A Losing Battle. I know I'm not the only one who has
reported pool pump RFI, which can be devastating.
Yesterday I noticed the 24.896 MHz signal strength on my calibrated K3
S-meter was S-8, which translates to 25 uv at the antenna terminal. On
that band my antenna is a rotary dipole, 100 ft away from the pool
pump. On other bands (10m and 6m) the strength is less, but still a
very serious interference when those bands are active and signal levels
are low. 12 meters WILL be active again in a few years.
If you are considering installation of new or replacement of old pool
equipment, I suggest you avoid Fluidra and Jandy products like the
plague. I also suggest you have a contract with the installer that
payment is contingent on no evidence of RFI generated by the equipment.
I have friends who have done this successfully with solar installers.
If they refuse to include such a clause, find another installer. Please
pass this on to all friends who are considering such a purchase. - Jim W6YA
