 If you're listening on AM you would not notice a "wobbly" carrier.

347
 8) Beginning to get nice am signal here. I always love AM. But, my noise level has been as high as s9. That's a huge issue in receiving.
SSTV sent at 2333Z
Signal starting to build up 2346 Z Stay On air You are Getting OUT
 :-X
 2335Z As My Guitar Weeps- Beetles
Using FT 900 because SDR is giving radio Cuba spurs and no signal. Wish SDR technology could evolve beyond spurring so much.
 Think off at 0105 Z Lost signal

348
  Heard lots of very nice sounds, including Springsteen, Youngstown, -That one makes me weep.
 I think by great audio and signal this was a test from Trash Can Radio. testing broadband transmitter.
I saw sidebands to over 10 kHz! ::)

349
Lots of tunes I would play too and the SSTV, just too funny. 8)

350
 >:(  Rushed down to listen, but nothing here at all no carrier trace. 0007Z

 8) Holy smokes, oldies !! 545 Here in Cherokee.
Thanks, music man
This is great music !
2304 Z Down By River.. 50's sound. I think of A and W rootbeer.
Sidebands are dancing to the beat here. This is one big station.
2317 Pushing too Hard
This dude is blasting 30 db over s 9! AM
2337 carrier off. show was a blast
Signal the strongest I have yet received here.


352
 :D I did hear this station, but could bot pull anything out of the mud. It was near the noise floor and for most of time below it.

353
0022 Z signal 5 9 plus here on Mt. Cherokee Ga , As usual nice audio.
0023- Beetles " I want to hold your Hand"
Some swisher or buzzer interference from time to time.
Condx seem good tonight.

Yes! ::)

354
 Dunno, but 6910 is a MARS frequency and if it was a pirate, the hams would be complaining to FCC. There are some frequencies in 41 meters, better to just avoid.  :P Also they would complain to the communications director for whatever branch of military that group is associated with. It would not necessarily have to be direct interference. FCC goes entirely on complaints .
Not much in that band that could get the complaints going with exception of 6910

355
 8)  I do hear a carrier, and at 2200 sounds like an Elvis song, but signal has lots of fading here. :-X
   " she got... ?? "
Did hear an Olah at 2203. Guess that was an ID
Some swishing bad VFOs and a weak buzzer as interference
Heard a DJ say "you heard".. young man's voice. Signal still up only slightly above noise.

The RF Workbench / Re: A 1 Kw output broadband package
« on: February 19, 2018, 0023 UTC »
 Well, Pigmeat, here is the logic. Do you want the freedom to switch between SSB or AM? Well, yes. That could mean a class AB/C switch or just a big heat sink to take the calories. Class E and D are indeed interesting to a newbie engineer type who wants to play on the bench. Yes, advances are HEAT less . The Baseband for any mode on shortwave unless we are talking a digital mode and if that be the case a BIG BAD linear amp will be needed.

If you are an equal lover of broadcast and engineering, after some thought and not wanting to REINVENT the wheel. I would choose a BIG BAD high gain FET (low drive) broadband amp. The exciter would be a DDS low power am or SSB exciter, 10 watts, or less with a pad to adjust drive.
BIG OLD BAD 100 volt or so DC powersupply. And you are set. There are predesigned FET amps with heat sinks in the KW range unfinished except for enclosure, harmonic filter and what ever else you want to throw inside the case.
An easy 250 watts HIgh FI am transmitter is born. Its NOT rocket science. Let the hard part be done by somebody else and not you because you will spend months just reinventing the donkey cart. :-X

 :(  No signal on Cherokee Mountain. Not heard. 1945 Z
Probably signed off?

360
 :D Yes, a fair signal S-8 small dips and fades. The format sounds suspiciously like CNR :-\
Montreal Rose is feeding me reception. Pretty good in Quebec.
