General Radio Discussion / FCC Public Notice 4126 dated August 12, 1988
« on: November 21, 2018, 1637 UTC »
So I am on the FCC ULS web site, looking at HF station licenses in the Industrial/Business Pool. The frequency authorizations on licenses often look like this: "000007.30000000-000008.10000000". This seems to authorize any frequency between 7.3 MHz and 8.1 MHz.
However, at the very bottom of the license are these words in the section that says Waivers/Conditions:
"Only those frequencies identified by PN 4126 released August 12, 1988 are available for use in the authorized frequency bands."
I spent some time searching for this Public Notice but can't seem to find a copy on line. Before I try writing to the FCC, does anyone have a copy of this Public Notice?

ID and Translation Requests / Re: Unid Time Station - 10 MHz
« on: November 20, 2018, 0057 UTC »
Thanks! I've heard this station multiple times this week.
Not many time stations left on HF -- some of the ones I heard decades ago (VNG, JJY, etc) have left HF completely. I hope WWV doesn't join that sad list.

ID and Translation Requests / Unid Time Station - 10 MHz
« on: November 19, 2018, 2204 UTC »
I am hearing a station on 10 MHz, under WWV, at 2153Z. There are voice announcements every 10 seconds, with a beep between the announcements. After the last announcement, there is a double (or perhaps a triple beep because WWV has their own beep which could mask the last one) to mark the new minute and the cycle continues.
I don't recognize the language -- maybe French, but I am not sure. I think they are announcing the time.
Any idea on which time station this may be? I know BPM China, and time stations in Brazil and Argentina are also on 10 MHz. I have not heard an ID.

What do you mean by “license comes with it”? License for what? The SDK? V4, V5?

The RF Workbench / Re: Q about strange tuning on a valve TX
« on: June 26, 2018, 0953 UTC »
I seem to remember an old ARRL handbook saying that when max power and plate current dip didn’t match, it might be an indicator of self oscillations/spurious emissions from the PA.

Longwave Loggings / Re: ICAO NDB Specifications
« on: September 04, 2017, 1334 UTC »
This site ( http://k4che.com/FL8/FL81.htm ) claims that the choice was based on the use of an electric motor to generate the tone. I don't know that I am convinced that is correct, but it is as reasonable as anything else. The good thing about a 1020 Hz tone is that it doesn't fall on an adjacent channel carrier frequency, making it easier to hear the ID when you have stations on both channels.

Longwave Loggings / Re: MSQ 353 kHz
« on: September 04, 2017, 1327 UTC »
MSQ is one of my locals...maybe the strongest at this QTH. I have long thought that it's spectrum was a bit "dirty", so the extra sideband energy you see doesn't surprise me.
