QSO Cuba Canada con¡¡¡¡¡25 MILIWATTS DE POTENCIA!!!!!!!
RX8: <00:52 UTC> <7,8 Hz> CO2DC de VE9DX OK fine jesus… let me drop my power… qrx will go to 1 watt…
now running 1 watt only Jesus… still copy me? CO2DC de VE9DX Email: <ve9dx@nb.sympatico.ca> <STOP> <-5 dB>
TX8: <00:54 UTC> VE9DX de CO2DC ok wiht one watt S/N: -5 dB, Marge: +21 dB go more down because u have enought merge go ahead down BK <STOP>
RX8: <00:55 UTC> <11,7 Hz> CO2DC de VE9DX CO2DC de VE9DX ok will go down to half watt…now 1/2 watt…. will drop it down to 1/4 watt qrx going to 1/4 watt…
now 1/4 watt now 1/4 watt copy ? CO2DC de VE9DX 1/4 watt
<STOP> <-10 dB>
TX8: <00:57 UTC> VE9DX de CO2DC no problem with 1/2 1/4 w go down S/N: -10 dB, Marge: +16 dB bk <STOP>
RX8: <00:58 UTC> <11,7 Hz> CO2DC de VE9DX
OK back up in power now… That waas measured on a Bird watt meter… so one really does not need power on this mode. Nice to know I can be heard with 1/4 watt,,,
Thanks for the test… again very 73 and gn for now… CU soon
CO2DC de VE9DX tnx fer QSO, 73. CO2DC de VE9DX sk <STOP> <-3 dB>
TX8: <01:00 UTC> VE9DX de CO2DC if u are able to go furthe down do it because if u calculate i will continue receiving u 10db under 1/4w simple calculation i dont knw if ur Bird is able to read miliwatts but i am sure u will come here in this moment without qrm with 0.02w bk <STOP>
RX8: <01:01 UTC> <11,7 Hz> CO2DC de VE9DX CO2DC de VE9DX OK here goes will go down in power some more…now 100 mw 100 mw 100mw do u still copy?
Email: <ve9dx@nb.sympatico.ca> CO2DC de VE9DX k <STOP> <-9 dB>
TX8: <01:03 UTC> VE9DX de CO2DC ok the 100mw go ahead down….bk <STOP>
RX8: <01:04 UTC> <11,7 Hz> CO2DC de VE9DX wow … this is awesome… here goes…now 50 mw 50 mw 50 mw 50 mw… this is about as low as I can go Jesus BTU CO2DC de VE9DX <STOP> <-14 dB>
TX8: <01:05 UTC> VE9DX de CO2DC ok 50mw and no mistake in any letter i will send you a copy of the log by mail but please contiue down no qrm now bk <STOP>
RX8: <01:06 UTC> <11,7 Hz> CO2DC de VE9DX CO2DC de VE9DX OK qsl… will try 25 mw…It is harèdtmeasure output now but I see 25 mw 25 mw 25 mw Hw? de VE9DX
<STOP> <-17 dB>
TX8: <01:07 UTC> VE9DX de CO2DC S/N: -17 dB, Marge: +9 dB ok first ligth mistake bt only one and if u have toruble with that Bird reading look for some other one hi hi… because it is too much for ROS <STOP>
RX8: <01:09 UTC> <11,7 Hz> dat•Mr]lòeÄshekx¤ru el <CANCEL> <-21 dB>
RX8: <01:09 UTC> <15,6 Hz> CO2DC de VE9DX OK now back up to 15 watts… sri I had an error… Hit the wrong key… well glad to know how well this program will work. I am learning fast that it works very well indeed. Have a sked coming up in 5 minutes on 2 mtrs with a stn in Ohio so I really must run… Tahnks for the great qso. I will look forward to ur email Jesus,,,
Again 73 and GN CO2DC de VE9DX sk sk qsy
<STOP> <-3 dB>
TX8: <01:12 UTC> VE9DX de CO2DC ok 73 i wll send u a copy of this log by mail tomorrow i u will see ur signal with 25 mw and i will send it to Mr. Ros 73 and prepare anothier >Bird that flies lower hi 73 mt friend VE9DX de CO2DC sk <STOP>
Observamos que el modo empleado es ROS 8/2250 ¿¿ Cual seria la potencia minima requerida para mantener el canal de comunicacion abierto,si usaran ROS 1/2250????.
Yo no puedo responder a esta pregunta.
