Ive heard variable speed HVAC units sometimes cause RFI. Does anyone have experience or knowledge about variable speed pool pumps? Specific model Im looking at is Energy efficient Pentair VS Intellif
Thanks, guys, for all the useful info. Taking Jim's comment "In general, variable speed motors should be assumed to be noisy until proven otherwise" I'm going to have to plan for that before doing th
If the only problem was a bad starting capacitor, my guess is you got a defective capacitor that is arc'ing. Call the service man back to try another one. If he just changed the capacitor because tha
Good question. Thanks but the power situation in Turks & Caicos is very different from USA. Electricity is about $.48 PER KILOWATT HOUR! Whats yours? Pool alone presently costs almost $300/month for
Thanks Phil. My post that crossed with yours explains my unique situation. 73, Jim K4QPL VP5M Sent from my iPhone _______________________________________________ RFI mailing list RFI@contesting.com h
Wow! Thats CA. Were on residential time of use here in NC and average for June was $.09 kWh or about 20% of VP5 rate! Ill deal with the RFI if I can just get my bill down some. Sent from my iPhone __
Thanks for all the input. Weve now sorta gone off the trail into HVAC, economics and other side discussion. I think my post inquiring about specific pool pumps and related RFI issues has been covered
Yes, very much so. Only recently has the Canadian owned utility company monopoly even allowed homeowners to use solar to reduce demand on their inefficient diesel powered generating system and previo
Great project Randy. I cant contribute any information now but Ill be very interested in your compilation for a VP5 installation in the future. 73, Jim K4QPL VP5M Sent from my iPhone ________________
So for no-shade, other than night time or clouds, whats the technical recommendation for say a 10kw non RFI system? Is it necessary to use batteries or does one just pull more or less from the grid a
I started a string a couple of months ago asking about RFI with variable speed drives like the Pentair pool pump for our rental property down at VP5. Just got back and here's the report for what it's
True. But dont dismiss the benefits out of hand. Variable speed pool pumps save us several hundred dollars per month at our rental property and contest station in VP5. $45 RF filters from Schaffner o
Does the solar panel RFI affect VHF FM or digital modes, especially WinLink? If not, good luck trying to get the ARRL top management to take serious action. HF is on the wrong side of the bread that
Cant offer specific help, but I would certainly be cautious about knocking on doors where you suspect powerful grow lights. They just might not be trying to get beautiful blossoms on their roses . Go
LOL! Thats certainly one good way of dealing with it. Maybe an unmarked van with antennas parked across the street might also encourage some circuit breakers to get pulled! Sent from my iPhone ______
Can't be specific on HVAC units, but the Schaffer line filters, available in various amperage ratings from Mouser can be inserted in the power circuits. Mouser 631-FN2070[ampere rating]. I Use them o
Very good comment. All wires are capable of being transmitting antennas, even that little thermostat or relay control wire. And ferrets do more good for hams than squirrels Sent from my iPhone ______
Hi Bob, We gotta support the ferrite industry! Seriously, youre correct. Choose the cure to match the problem. On the other hand, efficiency is not an obsession. Saving money just makes sense. I seld
Top quality Pentair VS pool pumps generate huge RFI. Not just cheap Chinese. We have two at VP5M. The only way to bring it down to acceptable levels is the brute force line filter as close as possibl
Ive mentioned this on the reflector before but I think all variable speed pool pumps including the two Pentair which I have at our VP5 property generate substantial RFI if not filtered. Fortunately t
