6930am (more or less) UNID (maybe OHR?) 2217z 8-07-2010

(1/1)

SW-J:
More as available ...

OHR if I had to guess ...

2220z Freq approx. 6932.2

2223z Freq approx 6932.0

2224z shift up to approx 6933.5 still LSB ...

2226z approx 6934.6

2229z Prop condx have chgd for the worse ... and I need to go get some Rotella T for the buggy ...

outhouse radio:
you missed the MODE    it is AM    10 watts carrier with a bunch of swing (PEP) up to 110 watts

Zoidberg:
Heard some tones that sounded like music just above 6930 and a weak carrier around 2300z, lost the signal before I could tune it in and ID anything.

They have a name for that; it's called ACSSB see: http://en.wikipedia.org/wiki/Amplitude-companded_single-sideband_modulation

Without getting too technical, let it suffice to say 'it' works best when using a receiver capable of AMS or AM/Synchronous detection (carrier restoration at the/on the 'receive end') especially if the transmitting signal 'wanders' around quite a bit (so I have found out determined these last few weeks!!! ALL IN GOOD FUN OHR!!) ...

   NO DOUBT IT IS FUN     Strange thing tho  the transmitter was running in AM MODE 10 watts carrier not SSB     I guess for AM MODE a guy is susposed to run a transmitter that doesn't have much modulation swing         Man you wouldn't like my old  transmitter  it's a SWINGER   LOL     nice links by the way
