After a long conversation with a local Federal prosecutor about the new
"anti bother" legislation I have decided it is pretty safe to post facts and avoid expressing personal opinions. So from time ot time I will post links to radio related information that I have found usefull. My only opinion about this link regards the realization that while I thought I was going a little overboard with the feritte for comon mode noise suppresion, I see I have to add a lot more to even approach 1K impedance! I have ripped out my entire radio room and intend "to do it right" this time. http://www.yccc.org/Articles/W1HIS/C...S2006Apr06.pdf The R200swl and r200slwer "at hotmail" and "at yahoo" accounts are abondoned. Given the rapid thread drift toward non radio topics I doubt if I will ever reply to any thread. Enjoy or ignore. Terry |

I have ripped out my entire radio room and intend "to do it right" this time. http://www.yccc.org/Articles/W1HIS/C...S2006Apr06.pdf Well! This certainly levels a well-placed karate chop at the concept of one-at-a-time ferrite beads, cores and chokes, doesn't it? It appears that outfitting one's radio gear with enough of these things could easily exceed the cost of the radio, antenna and monthly electric bills for 10 years! OTOH, for us guys (and I mean that in the NY/Chicago sense of the word, where girls and boys are all "guys") that live in the city, it may be our last best hope. Bruce Jensen |

At some point, it would make sense just to buy a Topaz line isolator
for power lines. You get surge suppresion as well. wrote: After a long conversation with a local Federal prosecutor about the new "anti bother" legislation I have decided it is pretty safe to post facts and avoid expressing personal opinions.

Nice paper, thanks.
I have been snooping around the house with my new Kaito KA1103. I have found only a couple of noisy appliances, but they are wicked noisy. 73 NEO |

Given the rapid thread drift toward non radio topics I doubt if I will ever reply to any thread. Enjoy or ignore. The information is geared for Ham transmit but some of it is useful on receive. If you have receive power mains noise problems then I recommend EMI filters that you can buy built into power strips. Those power strips are easy to buy and use. 1K ohm common mode choke is pretty good on a receive coax. More is always better of course. Lossy ferrite is good on the receive coax but as noted in the guy's paper it is a problem on transmit. -- Telamon Ventura, California |
