The editing on LPH#44 is complete, the show will be trial streamed at 8 PM CDT, in a few minutes, so I can hear the entire show and listen for errors.

Also, it’s a little overtime, if there is a necessary time-limit…. some weeks it’s been 55-minutes, other weeks 1-hour….
Stations haven’t said anything about the length.
As soon as I approve the show it will be ready for download.
Later maybe I’ll post a Table of Contents.
Timing Is Everything…
On my station I’ve noticed some episodes are cut off before you finish. This is because the playlists are automated and timed for break at the top of the hour.
Personally 55 minutes works better for me.
I can squeeze in the station ID, brief newscast and weather at the top of the hour. Then the episode runs its entirety.
I toyed with the idea of doing time compression with Adobe Audition to set the episodes all the same length.
That Was Easy
You have called the shots!
Or the shot.
The new time for the Low Power Hour will be 55-minutes.
It’s official.
I will whittle this one tonight until it fits.
Thank you.
Thank you Carl …
Can’t wait
Thank you Carl …
Can’t wait to hear the new show !!!!
Struggles at Midnight
The show clocked out at 1-hour 1-minute, so I shaved it down to the new time, 55-minutes.
This mouse has gotten uncooperative and seems to click and un-click things in strange ways, so the editing was like trying to drive while facing away from the wheel.
I think the show is o.k., but now my web service provider’s system has a personality problem and stalls, resets, fails and otherwise has prevented me from uploading.
I am going to have a giant sledge-hammer in sight here in the work station, to try to intimidate all these computer parts into working properly.
Here goes another try.
Reboot Success
Reboots are a true form of Artificial Intelligence. They manage to clear up problems that otherwise confuse computers.
LOW POWER HOUR NO. 44 is out there!

The Strange DX
That sounds a lot like spur emissions from a very noisy and interference emitting digital audio synthesizer..ie a musical keyboard, electronic piano etc.
Could be due to injection of that spur interference via the device’s power supply cord.
Or the Antekins have signaled and advising everyone to leave now before it’s too late!

I’m Busy Discussing This
The idea of spur emissions from a musical keyboard or synthesizer is an idea, but would it be at 1550kHz in perfect sync with other stations on the same frequency?
Would it go on for over three hours? (or even more?)
Could be, I suppose, might have been a rehearsal by a very serious electronic musician, but it also could have been one of the most classical examples of a one-time-only pirate transmission in the entire history of broadcasting.
Turning now to Low Power Hour News, No. 44 is officially released in a 55-minute edition, the new length standard.
Carl Blare will be revisiting earlier shows to study the feasibility of trimming all the shows to 55-minutes. This could be a long-term project.
Spur emissions
Spur emissions, especially those generated by a digital synthesizer are extremely wide band. Each frequency generated by the synthesizer can and will produce tons of square wave harmonics and if any of those harmonics aren’t filtered out well then they escape to anywhere they are going to go. They will not be centered on a specific frequency.
Did you tune the radio to each side of 1550 to see if this stuff was in fact on a carrier or if your radio was simply picking up wide band spur emissions?
Should have hooked up the Spec An to an antenna and tuned that frequency to “see” what was going on. If it happens again, I highly suggest you do.
3 hours wouldn’t be out of the ordinary for someone composing a musical piece on a synthesizer.
One time thing from some pirate operator? Possibly. But the characteristics of this received “digital hashing” noise does have very striking similar traits to that from a noisy digital synthesizer blasting the spectrum with junk.
RFB
Following the Theory
It did not occur to me at the time to tune either side of the unusual signal.
The Signal Analyzer would have been useless, because although it perfectly registers my own 1550kHz signal, the background radiation from afar is down in the noise.
Of course a serious loop antenna might be helpful to study the signal background, but I have not evolved to that stage as of this time.
But there is no doubt that RFB knows his RF, and I now have a wider scope of viewpoint.
Or, a wider view-scope.
Wider Is Better…Sometimes
Is why I suggested connecting a good antenna to the analyzer.
Perhaps you should build one specifically for this purpose, and
could be a new extended department of the antenna research projects.
The right antenna for the right job! 😉
And with tuning the radio to either side of the suspected frequency, you can better determine how that unusual signal is actually being picked up as well as how it’s finding it’s way onto the MW band.
I have a feeling your going to find what I was describing, these strange sounds spread across a wide part of the band, and the receiver used to record it simply picked up what was “passing through” on that frequency and others at the same time.
Since it fades in and out, and the times this happened, a lot of changes take place to a power grid’s inductance and loading characteristics. If conditions are right, that induced spur emissions from a digital synthesizer very well could carry on the power lines from across town and it will sound like it was from some far away pirate flamethrower.
Its the same effect on an AM radio like placing one of those large loops near it with no actual connection and the radio suddenly has incredible reception sensitivity.
If you monitor your CC’s coupler VSWR meter in TEST mode, you will actually see the meter reflect these load changes on the grid. The meter will move slightly.
These changes can go either way, bring in more stations that the lines are re-radiating, or even wide band interference from things like digital synthesizers injecting that noise via it’s own power supply, audio grounds, etc etc, or noise or bring in nothing!
