Poor performance on the BCB. That's pretty relative. I had a high school FM radio station transmitter that was supposedly well filtered. Still, it was very possible for all the attached wiring and

Thank you to all who responded to my question. I have a clearer picture now. It came about because I live within 5Km of a number of high power transmitters, including the famous 5AN, and a lot of the

To expand on that nice description: Field strength and receiver sensitivity and receiver meter readings are different animals. Receiver sensitivity is just one way to rate how a receiver will "hear" a

Hi Phillips, Millivots per meter (mV/m) is a way of defining a station's expected (or measured) field strength at a receiving location. It matters little whether that signal is ultimately impressed on

Hello All, After reading Nick's long report of vibrant TP's from 1130-1300 yesterday it certainly seemed like my lackluster sunrise enhancement session (after 1300) got the short end of the

I am still trying to get my cotton wool stuffed brain around this parameter. Does this parameter only apply to receivers with ferrite antennas? Is this the "missing" piece of the puzzle that has

Congrats! ... and ditto. Hearing Voice of Russia from Grigoriopol, Moldova on 1413 KHz now at 19:30 UTC which is about 1100 miles from my QTH. Have a PL-310 on order but it has not arrived so this

I've managed to log a new medium wave station. 8/31/14 1239 GMT 750 kHz KSEO, Durant OK (0.22 kW @ 276 km/172 mi). Heard by chance while listening to KMMJ, Lexington NE, with a promo for the

Hello All, The Asians seem to be a little slow in getting out of the gate this season, and their performance this morning followed the same lackluster pattern. With the exception of 972-HLCA and a

Thank you, Bill... very comfortably confusing. Actually, pretty nicely explained. Joe Rotello / Knoxville, TN / USA

Confusion may also arise from the use of u for µ when the latter is not readily available on the keyboard. Michael

Hi Bruce, Sorry to confuse. I used dBu-dBµV/m to try to show that they are the same thing. Should have stated dBu (equivalent to dBµV/m). Corrected paragraph: The modern DSP receivers like the

Whatis.com says it better then me! "The standard unit of electric field (E-field) strength is the volt per meter (V/m). An E field of 1 V/m is represented by a potential difference of 1 V existing

This can be a confusing subject, so please allow me to offer this explanation. The common unit used in measuring received field strength is volts per meter, or usually, millivolts/meter 'mV/m'

Hello All, Another fairly mediocre band presented itself this morning, although in an improvement over yesterday a much greater variety of Asians managed some form of weak audio. Vibrant audio was

In trying to "simplify" an answer, engineers may get more "complicated"... Signal strength is typically expressed in voltage per length or signal power received by a reference antenna. High-powered
