28 & 24 MHz intruders - Alarming report by DK2OM
Date Until:
15/11/2011
Hi friends,
28 - 29.7 MHz is completely over-flooded by CIS taxis in FM (Russia, Belorussia and Ukraine). The woman on 28195 is located in Kiev (UKR), the taxi service on 28155 transmitting from Russia. 28200 is also abused by Russian military, F1B, 100 Bd, 150 Hz, vocoder Yakhta synchro signal, located in UFA, Russia. Uli (DJ9KR) and me need few seconds to hear if a language is Russian or Arabic. Arabic voices are very rare on 28 MHz. The last days I found CIS taxis even on 25100. One day they will destroy our 24 MHz band, too.
Another large problem are the Codar HF Radars on 24 MHz. They are transmitting with 2 sweeps/sec, sounding a bit like a pasture fence. (PSE look for the soundfiles on www.iarums-r1.org) K0BOG, Chuck, is interested in such signals. I think we should help him with observations and reports. A worldwide collection of Codars on our bands will help to show the unkind and sometimes bold methods of these people. The signals are stretching over 100 - 500 kHz!!! If you are not sure if you have found a Codar, send me WAV-file (44 kHz sampling rate appreciated - 5 MB no problem). Analysing digital signals on our bands is my daily job.
