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
Avoid ones with an Inverter for variable speed. No personal experience, but I've gathered that info here and other places over the past 10 years or so. Unfortunately it appears all mini-split AC have
I grow tomatoes, peppers, cucs, and cantaloupe. I start from seed on March 1st and used to put up with VHF desense while my grow was in progress. I did not detect anything on HF, but I'm mostly FT8.
I am running a "hockey puck" LED that takes a "wedge" style bulb. It takes ~12v. I feed it with a conventional doorbell transformer. I also ran it on a small 12v shack PS for a while. Seems RFI free.
I have an EU3000is. Purchased about 20 years ago. It's both RF and AF quiet. I base this upon non-scientific observations. It went to about 8 Field Days (HF) and 15 VHF Mountaintopping events (VHF -
I disagree on that on that. Ive been retired about 13 years and had the inverter generator about 10 years prior to that. If you can find historical data on the EU3000is and when it appeared, Ill be h
Sounds about right. I was an early adopter. Hardly anyone was aware they existed at the time of my purchase. They only took note of my generator when they walked by it and could not hear it as it was
