Equipment / Re: 11 Meter SW BX Band....
« on: May 05, 2014, 0732 UTC »
I got some Day's a lot of Broadcasting Station's on CB here in Europa.
Not every Station send a ID but a lot OP enjoy the Prop. on 11m.
I copy the first ID from a BX Station from Radio101 transmit on the CB Channel seven,years ago.
This BX tx automatic if the short skip prop.(ES) is good. -> www.radio101.de/radio101/how_to_d.htm

To made a littel TX is very easy,the same like on 48m plus the LPF to cut Freq. above 30MHz.
But maybe it will be great if anybody post a BX Station that tx on 11m online,like cluster.dk for DX.

Someday's,with good weather,sunny sky, FreeRadioBumbelstock is portabel on air ;D

More people should to try on 11m,with god prop. the signal will travel far....

Good DX!

Playing now with S 8.
Sinpo 44444,great Signal!

Thank's for TX!

Yesterday, 10.03.14 at 1915UTC, i listen to Pink Panther Radio again with my simple indoor RX Degen 1103 plus the Teleskop Ant.!
Great Signal from the Netherland's for a indoor Reception ;D
Audio via http://youtu.be/A9-0Nr3gbVc!

Thank's, PinkPanther!

The Loby for 'AM' will be smaller and smaller.. Sometimes i think nobody interessted to MW anymore.. Some people just ask,why i have the 'old' MW switch on my Car Radio :D,they just wont to have 'USB Stick Sound' :P
Got the same noise problemes at my home,the best thing is to walk outside from town and spend so time into the nature with the radio in the hand ;D

Good DX!

Jordan,100%  ;)
I have done this to a AM CB Rig plus my modified TR45 Transverter to tx portabel some music.
You simply just take the wire setup from the mic jack, 3,5mm mono jack wired to 'NF' Pin and Ground and one switch to do 'TX' to the 'Ground'.  I use just a CD Player or other Audio Source.
Made this with the 8 Pin Alinco Mic Connector and it work's also. Audio comming good,you just take a look about the Audio Level from your Source,this should not be too high.

Good DX!

MW Loggings / Re: 1646kHz AM TX UNID

Today 21.01.14 1940utc same AM TX with Sinpo 44444 ;D
Anybody now the ID? :)

Hello Token! I'am a little bit confused ???
Made a sound record about 1900kbit and change the rx modulation during the record.
First RX in AM,than switch to FM,than USB/LSB,and i also switch the Frequenz from 6260kHz up to 6280kHz plus chance the filter settings and i do not copy a clean voice >:(
Do you get any ID from TX?

Greeting's ;D

Anybody copy right now this TX on 6270kHz??
Modulation from TX is unknow,copy loud female voice,but don't read it..
At my icom plus wire ant. signal 8,at my degen plus mag. loop pointed west/east signal 8 also,copy the tx also on WebSDR RX in NL.
But i don't now if it realy tx on 6270kHz or is it a strong overwave from any broadcast???
1747utc Signal still S8!!
1820utc off ??? bevor, the voice was German!

Greeting's ;D
