Title: Sternradio Test 6962 AM 0450 UTC 28 MAR 2024
Post by: canswl on March 28, 2024, 0459 UTC
Really strong tonight into Masset, BC at 04:50 tune-in using USB + C tonight.
Playing:  Like to Thank My Buddies by Combichrist
I'm occasionally seeing something on the LSB at times as well.  Interesting!
Measuring at 6961.666

Was like a supressed LSB signal when I first tuned in.

S9 on my MLA-30. Great audio. SIO: 555

I keep farting with turning sidebands on and off while keeping the carrier.  Seems like I get more "punch" on the remote SDRs with just one sideband.  No surprise there.  How is the TX? (Also should this be a new thread?)

It should be possible to do Asymmetrical Sideband on AM as well where one sideband has 125% modulation and the other have 75% modulation. I know some AM stations nearby me do it to reach farther

It's fun to watch you switch between Carrier + USB or Carrier + LSB or full AM. tonight.  Still going strong at 05:17....almost time for me to pack it in!  73,  Walt (on the ground in Masset, having just installed a brand new KiwiSDR).

Vestigal Sideband almost.  Though I suspect they're required to have both sideband.  Curious though to see how the AM compatible sideband goes.  I'm still running the same carrier levels as I would with full AM.  In theory, a classic diode detector should be able to listen as well.

~S9 and SIO 544 trending 545 at 0524z via Airspy HF+D and 31' vertical.

BTW, Stereo Tool can generate asymmetrical AM modulation if interested.
