The bad news is that Panasonic is just one manufacturer, and there are already millions of plasma TVs in service that are likely to continue spewing out their garbage for years to come. Those things
A company was caught providing the FCC one thing to get part 15 certification, then selling something else. This involves 433 MHz which most hams probably don't care about, but it reveals what goes o
If you suspect a near-by light is being used for some kind of "illegal" growing operation, you might be able to use that as leverage, to your advantage. If the people with the lights are less than t
sound of broadband plasma TV generated noise. This noise averaged 5 dB over S-9 on 1.900 MHz, from a noise source 200 ft from his receiving antenna. Yours may not be identical to this sample since r
I always try to be helpful, but I don't curtail my operation because of interference to susceptible poorly designed consumer junk. My philosophy has always been to 'Co-operate, but OPERATE'. Fortunat
Sometimes it's best to try to by-pass the bureaucracy and get in touch directly with the linemen who actually do the work, or else the head honcho of the operation. Years ago I had a severe line nois
Those of us in "illegal grow" states might actually be at a substantial advantage. I personally couldn't care less what kind of plants a neighbour is growing on his own property, especially for his
I think you are being a slightly paranoid. How are at risk of being sued for informing someone, especially a law-violator, that they are attracting attention by generating a nuisance in the community
I think that would be opening a can of worms you would rather keep closed. Not to condone breaking any laws, but I would much rather have someone in the house next door minding his own business and
I have a 20 y.o. Raytheon RadarRange. It still works fine, but it used to send my wi-fi internet 'radio', about 10 ft away, into buffering mode while it was running. The laptop was never affected. W

There are still BPL systems in operation? I thought that whole technology had pretty much fizzled out by now because it performed so poorly. Don k4kyv _______________________________________________
The best test would be to bring along a portable or mobile HF receiver and see what the background noise is like. They may have tried BPL, but discontinued it but haven't pulled all the hardware off
Regarding thermocouple RF ammeters, from my experience the calibration between two identical meters (same range, same manufacturer, same type number) can vary considerably. The best way to check is t
"Tuned feedline" means the load on the transmission line is different from the surge impedance, so it operates with substantial standing waves and normally must be used with some kind of a tuner. Th
The window a/c in my shack finally gave up the ghost after 40 years of reliable service. I need a replacement right away, since especially with the station equipment running it gets too hot in summer
Shack is 24' X 32' with 12' ceiling (formerly a one-room school house). Building is unshaded in direct sunlight in afternoon. QRO transmitters and other station equipment give off considerable heat.
What does this have to do with RFI? Doesn't most if not all the RFI hash from solar panels emanate from the inverter, not the solar cells themselves? _______________________________________________ R
I just installed a 24k BTU DIY model to replace the old window unit in the shack. It works great so far and is whisper quiet acoustically. No RFI on any band with my beverage, or dipole located about
I recently installed a Mr Cool mini-split air conditioner in the shack. It works great and is very quiet (acoustically). It doesn't affect any of my outdoor antennas, but I have to turn it off when u
