LF: Another Eb-Night

[Markus Vester <markusvester@aol.com>]

I intend to get on for another night:

Frequency 137490 Hz 
6 characters, 8K19A, CRC 16, 3 second symbols
Starting on odd half hours  23:30, 0:30 etc. +0.3 s

Note that I will be transmitting several different messages, so if you've got one you still haven't seen them all ;-)

Domenico, Riccardo, would you like to join in on this freq, or maybe at +- 1 Hz? Who else?

Best 73,
Markus (DF6NM)

We could move closer together, e.g. 137520 and 137519 Hz. Although the higher order sidebands may overlap, there should be no mutual interference because of orthogonal symbols, i.e. the "other" carrier going through exact multiples of 360° during the symbol integration time.

73, Markus

The 0000Z transmission (first one captured tonight) was best this evening ... copy below. Similar copy on 0100Z transmission, no copy on 0200Z and 1.8 dB Eb/N0 on 0300Z.

 

Marcus and Domenico ... unfortunately just noticed that the setup didn't have sufficient bandwidth to include your frequency.
