Token is it true when I hear Andrews I am hearing a relay closer to California-and if so-do you have any idea where said relay(s) are located? I personally feel if I can hear New York Radio and New York ATCs here-why wouldn't it be possible to get Andrews proper also? Thanks
Ridgescan, as far as I know there is no way to tell for sure what transmitter site you are actually hearing, although there are indicators. Andrews has the ability to use any or all of the transmitter sites, but as far as I know they generally use the local Andrews site or occasionally the Offut NE site except during EAMs, then they often use all of the sites.
So, the majority of the time you are most likely hearing Andrews direct.
oops I forgot to type in to Andrews,, What are you the forum police?
Why would you think I was the forum police? I asked merely to get a feeling for if you had an understanding of how the HF-GCS network operates. By which I mean it is possible for a transmission to be sent , for example, from “West Coast Global” (the old McClellan AFB, Sacramento, CA) and still use the callsign of “Andrews”. All HF-GCS transmitter sites Worldwide can be remotely controlled by “Andrews”.
As I said above to ridgescan, in general, except for EAMs, when you hear “Andrews” you are hearing direct from Andrews. However, I have seen Andrews use both the Offut and the West Coast Global transmitters (same voice, same “Andrews” call sign, but preceded by the digital link audio tones and different transmitter as determined by TX characteristics, matched to Offut and West Coast Global), and I assume (and open source documentation supports) they can use any of them around the World just like that. During Andrews originated EAMs multiple transmitters are almost always selected, sometimes all of them in the network. EAMs that originate from other sources may or may not use multiple transmitters, depending on the source.
