Nothing. Yes. I have nearby solar as well, new install. Nothing heard. Ideally you/we will take noise floor measurements before and after solar setup is installed. I've been taking daily noise readin
Interesting thought. But water being a conductor would probably work as an antenna. I vaguely recall a military antenna based upon water spouts of the proper length shooting out of the ocean from top
I have 6 Sonos. I've not noticed any problems with 100w HF and 300w 2 meter. However, most of the time, most of them are unplugged as I'm listening to my ham radios / scanners. 7 3 Bob N2SCJ I'm thin
I see its listed as "Commercial Electric". That should be a tip off. Commercial lights are allowed to be noisier than one designed for home use. Sorry, can't quote the regulation, but it's been discu
Looks like I need a new GAS dryer. I started looking at a candidate and saw it has an inverter. Ut, oh. Not that one. Can anyone give me some model numbers of Gas Dryer(s) that are quiet? I'll take a
Some of the dimmer packaging says "RF Quiet" or similar verbiage. If it does not say that, it's probably noisy. Bob <snip> Lutron I know someone who used to for for them, and he says all the designs
How far away from the antennas? 7 3 Bob N2SCJ All, I also just replaced my complete HVAC system (AC and gas furnace, air handler, etc) this past September. I chose a Trade system with a non variable
I've noticed that one of my computers emits RFI, but it's coming from the HDMI cable. I notice it mostly on 70cm/445.200. To a lesser extent, I've noticed it on the 6m SSB portion of band. It's very
Thanks for the comments. I ordered one of the newer 8K cables and will give that a shot. The description was bragging about how its "triple shielded", so maybe it's better. I recall the ones I'm usin
Anyone had any RFI experience with Weil-McLain CGI-4. It looks to be somewhat low tech which Im hoping minimizes RFI. The controller is what I am mostly concerned with. Ive not found out what is in i
I had the SS-30 (no meters) in the '90s. No formal testing, just observations. It was RF quiet, I mostly used it on VHF but at least once on HF. It had a regulation problem if RF was in the shack, su
I have Honda EU3000is. It has been on several field days, and several VHF+ mountaintopping events over a period of about 10 years. No RFI noticed. Bob N2SCJ I have a Honda EU2000ic and an EC2200i and
Have you ruled out the RV converter causing RFI? I have to leave my RV unplugged over the winter as its under my HF antenna and causes interference. My converter also causes interference to broadcast
If you have control over what goes in the RV, you might want to specify an IOTA Engineering converter. This is their page: https://www.iotaengineering.com/products/dls-power-converters-battery-charge
I use this one with the supplied wall wart. https://www.parts-express.com/dayton-audio-dta-1-class-d-ac-dc-battery-powered-mini-amplifier-15-wpc--300-380 I feed spkr audio to line-in on a mixer, then
Today I noticed an EMI standard of EN55015 on a power supply. Does this standard mean much? Are there others to look for when selecting a switching power supply? I am using a doorbell transformer for
Any word on Vision Solar LLC? Quiet or noisy installs? Panels will be about 20 feet from my VHF antennas. HF perhaps 30 feet. Hopefully, the numbers don't work for them and they pass on the install.
False alarm. It was a bossy telemarketer that got her to accept a visit. She was not interested but let salesperson in anyway. She did not qualify and was not the homeowner. I told her if she ever ne
I purchased the RS-15-12 switcher. https://www.trcelectronics.com/ecomm/pdf/rs15.pdf. The metal case looked promising for keeping RF inside the unit. So far its quiet on HF. I have not tuned from 6m
The SMPS will have 10w of its 15w capacity in use if I continue to move along with this project. This is to replace a noisy SMPS inside a LED light housing with a LED / external PS combination. The l
