 8) Same was heard around 6925 on 17th Feb and a day earlier. Sending is bizarre as if looking code up in a chart?

 8) 2303 some Creo blues .. signal s9 plus FT 900 vertical on Cherokee Mountain.

Utility / AWE 6947 USB 2251 17 Feb 2018

 Repeated in Morse AWE, seems to be simultaneously packet. Same message, apparently SHOCK and AWE ? :-X
 Another US Military station seems to be active on 6940 packets and repeated spacer DITs
I can't decode packet, probably encrypted ? Sounds like a beacon test. Military always squats where ever. Its not under FCC , but this could also be CIA out of Virginia? Mystery streams. It wasn't there before today.
Can't ID it as military so its quite possibly spy CIA or some other clandestine

 8)  Happy to say nice signal here 434 S-7 @ 2229
   Format seems to be fusion jazz.
   Very shallow fades here on Cherokee Mountain. :-X

 :o  1455 Z Hear VOA sign on and then Jimmy Hendrix, signal faded and out 1459. Although I didn't decode SSTV that is an awesome  3d IMAGE of the moon. Been there and that Crater is deep, man ;D

 8)  Signal 434
  Seems to be classic rock.  8)

 :D Strong signal 555
Cherokee Mountains ;D
I really do not like RAP in the slightest. But that's what this operators likes best and its on now 8)

 8)  Readable with quite a bit noise and fading here on Cherokee Mountain.

 :D  Code station, soundings like poor hand keying. Spy station?
   Signal 334 :o

 Broken copy.. but I did copy " qui" and Jurn sitm ouf dive ?? :P
Is it English? Cipher? Could ouf dive be " our lives"
 The rate of keying shifts. However what solid copy  I have establishes not a language, more a cipher.

 :) Yeah a bit strange, I heard Spanish male.. "Hola Hola.. CQ CQ.. "
This band is a pirate ham or cb space for some I guess. Well make use of the space.

371
 ::)  Yes, a signal about 355. Weak but very readable.
At 0023- Rap Tune of some kind
    0024 - Strong Intro Rock Beat
    0030- Signal programming stopped without ID ::)

Comment- While programming this station had exceptionally good audio-Certainly within bandwidth 3 kHz.

 Oh dear the house of cranky old men.  :P
That said, keep the ego in place mates. I posted for information only, since coming into the area I think construction is really my first love. However, being outside RF for at least 12 years, I am shazammed by material sciences and what its brought forth.
Recall fifty years ago a 600 watts AM transmitter would fill a garage.
Peace Bros ;D

  The point here, I think, is the amp is broadband and will produce Kw plus 1.7-Fm bands. Just Driver protection and of course clean the bands with harmonic LPF. The class C mod is said 80 percent efficient at VHF. I would expect same HF.
If it could do kw peak, then surely it will do 300 watts fully modulated AM.
Now here is another FET miracle amp with 5 watts it pushes 1.7 kw.
The demo person shows power on Bird watt meter Vs a Chinese watt meter. Well, they seem right on.
So Class E Be fine if you are a high power licensed station, because the electric utility bills are quite a bit less with 50Kw output.
But , again the technology is there for trade offs and choices.
BTW I have several BCE Bricks.. one does 300 watts and it runs stone cold, drives with 1 watt.
I assume it has to be class E design, but its not a new amplifier, had it in closet for ten years.

 ;D The engineers showed this design way back in 2005, no longer front line.
They also instead of toroids (labor intensive) they designed PC board coaxial matching. They also ran the pallet at full bore 1 kw at FM band frequencies switch between the two worst load scenarios that BLOW and explode systems. That is NO load (open) and short circuit. The damn thing kept pumping.
Drive for 1 kw out was 5 watts, they warned on could blow the system by OVER DRIVE !!
Technology way better than I ever thought!

 :o Its funny I saw a discussion of a pirate radio that was FCC part 15 approved. When I was a kid, the FCC allowed 100 milliwaatt walkie talkies, my brothers had a set and I could hear them maybe half mile out. Later FCC with demands from corporate broadcasters changed it to millivolts at very close distance to antenna. That says a part 15 transmitter will be lucky to be receivable across the street !
