I've been able to pick up Military Satellites in the 260 Mhz FM range with
mine, just using a 220 Mhz Ham Rubber Duck antenna! Most milsat listening you need a beam antenna with a preamp, but not with the PRO-43! For that reason alone I won't sell mine!

Looks mighty suspicious to me. It aint "that" great of a scanner. J |

Thats the reason why you need a beam and preamp, or a dish with a LNA. And you want us to believe a consumer grade RS handheld can do this feat with just a rubber duck??????? Come on. J |

I have no reason to lie...I was surprised to. I've heard military callsigns
and Spanish and Russian 2-way conversations... Frank "Jeff" wrote in message news:2EbCe.159171$_o.111663@attbi_s71... "Frank Bals" wrote in message ...

I didnt mean to imply you were lieing. I really did not think this was possible. Can you give some specific freqs. Id like to try them on my VR 5K on a discone with low loss cable. I have found discones pretty good at catching signals coming down from a high angle. Good listening J |

I don't know how the military satellites in question compare, but it is
possible to pick up the amateur LEO satellites and the ISS with a handheld and decent ducky. Of course a whip or beam works better, but if the pass is high enough and your antenna is pointed the right direction, it can be done. The time window is narrow, so you really have to actively chase the signal and adjust for doppler shift as well. - Doug "Jeff" wrote in message news:2EbCe.159171$_o.111663@attbi_s71...

My ICOM IC-T7 does a great job on the ISS even with the stock rubber duck while it
is hanging on my belt. I can count on a good signal as soon as the ISS comes over the horizon. I have also managed to copy some military satellite traffic on my PRO-43, but the signals were pretty marginal on the rubber duck. Mind you, at 45N, I'm probably on the edge of the footprint.

I have also picked up UHF mil satellites on my PRO-43 and stock rubber
duck. It was comms between McMurdo, Antarctica and the mainland at around 261.?MHz This was from one of the new UHF follow on sats, which is a little hotter than previous series but was loud and clear on the rubber ant. The signal was first picked up using a military satcom antenna and then I switched to the rubber ant. I have owned a lot of scanners, commercial and mil radios and the PRO-43 is the best analog hand held scanner I have found. m.

Why should there any difference to my satellite handheld phone, which also works just with some flimsy antenna?! regards - Ralph -- Want to get in touch? http://www.radio-link.net/whereisralph.txt |

Why should there any difference to my satellite handheld phone, which also works just with some flimsy antenna?! -------------------------------------------------------------------------- Years ago I bought a Drake TR 270 to do amateur sat. work. (2mtr. uplink and 440 downlink) when I figured out that I was going to have to get for an antenna and possibly a dual rotor setup to track the sat. I dropped the idea. I think at that time you needed a beam with about 12db of gain for it to work reliably. That translates into about a 14-15 element dual polarized beam. That is one big antenna. Plus any mil-sat equipment Ive ever seen invariably use the little mini dish's to use in conjunction with it. Thats where I got the idea. I guess things have changed. I know the signals that come down from space are extremely low power,, with the possible exception to ISS, I think they may be beaming their signals to earth and running at a higher power so people can pick them up easily. A geo-synchronous sat. at 25,000 miles out running on 40-50 watts isnt much power. The OP gave me some freqs. to try on my VR 5K and Im going to give it a shot and see what I come up with.. I guess I had a case of "open mouth and insert foot" J |

Can be easily done with a PRO-43, its nearly as sensitive as the radios
used for satcom. One of the early satcom radios (PSC-3) used a simple short whip to receive selective calling signals via the satellite while the radio was on a G.I.s back. He would then attach the larger CP antenna to transmit back to the satellite. You can uplink to some the UHF military satellites with as little as 5w into a CP 5dBi gain antenna. Normal power is about 20w. A dish for UHF sats?? Maybe you should read up on typical equipment used for this.... Ralph A.
