In a firm far away and long ago, I was the R&D EMC design engineer. We were selling subscriber line cards to telco's all over the United States our line cards were touted as handling 90% of all telep
I've been intrigued by the ZS1AN's cascade of a voltage "Balun" for the impedance desired, followed by a current Balun to ensure balance. Cortland KA5S _______________________________________________
I have suggested that those bothered by plasma televisions make an offer to the owners: if they will donate the television to the officers club, air traffic controllers lounge, or avionics shop at a
Saw that. The article shows good balance with his resistive test, but doesn't say much about efficiency mismatched. Cores I dealt with working in EMC were usually Fair-Rite 44 or Steward/Laird 28, no
It is worthwhile for another reason as well; donating the offending devices to organizations and offices near government HF and VHF receivers makes it more likely the devices will be banned everywher

IF -- this is not always *necessary* -- we want to see if currents in a 2-wire feedline are unbalanced, I think a symmetrically placed ferrite core of appropriate diameter around BOTH conductors, wit
Since reception depends on uncontrollable parameters of propagation, antenna system and receiver performance, adjacent-channel rejection, etc., there are NO quantified definitions of harmful interfer

Back in the days of the open air EMC test site, when numerous ambient TV and radio signals had to be worked around, it was quite common to sync the spectrum analyzer to the line frequency and see the
There's no need to add irrelevant regulations. First, the FCC has already SAID part 15 isn't enough, addressing "Parties responsible for equipment compliance": § 15.15 General technical requirements.
True... but they keep the pipes in my basement from freezing. Cortland ka5s _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.com/mailman/lis

In a discussion now underway on the IEEE EMC-PSTC mailing list, one addressing the issue that Part 15 standards allow emissions too high to assure non-interference, I suggested that what the FCC is
You may find it easier to locate the emitter by listening on 65, 97.5, 130 or 162.5 KHz with a LW or VLF receiver. Some handhelds will tune as low as 100 KHz, and some of the portables (AOR5000, for
