Hi all,

Not a very good result on this frequency. When it was on 15435 the results were much better to perfect. My results from Flevo on this frequency were also much better, but at a different time of the day. The SNR spectrum seems different in the two halfs and there was present a co-channel interference. The TX location and DRMcalc label are of course wrong, not updated.See the log.

Rather bad with on-channel interference so that I got annoyed by the large number of dropouts and switched off.

This frequency is being attacked on both sides from 2 "wideband" AM Stations +/- 10 khz. See attached screens. This is a weak point for DRM.:eek:

Hi all.

Her is report over transmission this evning , it was very remarkable propagation
on this freq. I test 3 antenna , 8m vertical for 10Mhz , dipole for 14Mhz and my home made, BBA20 antenna only 20Cm long. All antenna peak S9+40db on S-meter very slow QSB BTW 20db/40db. For best SNR I switch in att.-20db from antenna.

Best SNR give BBA20 antenna.

:confused:

SNR Maximum [dB]: 41.7 :eek:
nothing more to say to the rf signal... :D
... but 14.56 kbps with this signal is nothing but a bad joke. :rolleyes:
