Doc, I have two laptops I use for ham radio purposes: a Mac iBook 900 and an older Dell Latitude 300 (runs Windows 98). Although my Mac is online via a portable satellite internet system (Hughes ne D
The Dell works off 20vdc while I *think* my Mac iBook is a nominal 16v. I use the Dell dc-dc adaptor/converter made specifically by Dell for Dell Latitudes; found it on eBay for about $15. I suppose
Most decent-sized RV suppliers either stock solar/wind charger controllers or can easily order them. Solar panels, per se don't normally come equipped with internal controllers. As a fulltime RVer, I
Kelly, I don't see anyone else jumping in to answer, so I'll give it a shot although somebody else may provide better information. Powerline noise on VHF (diminishing as one goes lower in the HF band
I lived in very rural upstate NY where lightning is a fact of life, especially in summer. Almost every barn (I could see nine barns in a two-mile radius from the roof of my house) is equipped with si
Not sure it's pertinent here, but I also have high white noise levels (S4 to S6, sometimes more, sometimes less) on 40m with a trap dipole (10, 15, 20, 40m) up 40' in the middle. And I'm located far

Yeah, I sure do. I bought a Honda Eu1000i this past February after having major RFI problems with a Mitsubishi 600/900w inverter-generator and have been having all sorts of the same RFI problems with
Could you expand on this a little with a description of how the Hondas were used, e.g., distance from the radios and antennas, any line or common mode filters installed, running through batteries, ba
Alternatively, apparently there are enough Honda inverter-generators which do create enough RFI to require articles on RFI suppression to be written: http://www.dellroy.com/W4EF's-Ham-Radio-Page/Port
Chuck, very good story and good work! Hams are constantly blamed for any type of interference by neighbors' who are having electronic entertainment problems. I'm frequently catching heat (albeit frie
To add to Mike's comments, I lived for 20 years within 200 feet of a 115kv line which crossed over my property and I experienced no RFI or other problems whatsoever. If anything, I considered all tho
Down here in Arizona, APS (AZ Power System) could also take some lessons from NYSEG. There are continuous MILES of leaky lines which are so bad, the noise drowns out my car's AM radio and I have a to
Yes. I have three laptops (old Dell Latitude 300, older Mac PowerBook 1400, newer Mac iBook 900 [main computer]). All three are RFI noisy while listening on HF when I have them plugged into commercia
I absolutely agree that it is seldom a simple issue with RFI. It also occurs to me that my newest Mac which causes the most RFI is also equipped with a wireless card meaning it also has an antenna (l
Ron et al, I disagree with the last sentence regarding RFI due to traffic signals on 2m, at least within Arizona (Prescott [my home QTH], Phoenix, Flagstaff, Tucson, and many other AZ locations). My

Pete et al-- In my 51 years of experience in ham radio including 24 years in the Army Signal Corps, I have long learned that lightning is like the 800-lb gorilla: it goes where it wants to go despite
