Joint digipeating ops between ISS and PCsat 2-10 Feb


This was posted over on the SAREX list and I know

I am not supposed to cross post, but in case anyone

missed it.


The point here is that we will have two satellites both

supporting the identical alias of WIDE and so  you will get 

not the usual 6 passes a day, but 12 or more  passes a day 

on 145.825 to do a DIGIpeat QSO.  But of course success 

depends on everyone SHARING the asset and NOT 

transmitting too oftern.




Also there may be a rare opportunity to do dual hops.

But again, imagine the chance of the ISS or PCsat

hearing the other one, 3000 miles away when the

145.825 channel is totally saturated with inconsiderate

stations transmitting so often that the channel is 100%

full.   a dual hop success will NEVER HAPPEN.




THus, I hope that most of you will do like I will

do, and that is just WATCH.  See what others are

doing and get your joys by analyzing what you see

on the downlink.  Remember, HAM radio is also

fun to just monitor!  If everyone is transimtting

no one will hear anything.


Please do not send packets too often and for newcommers 

NEVER ATTEMPT ANY KIND of connection.  that is the 

worst possible thing to do via PCSAT or ISS.  It just jams

 the frequency with useless CONNECT, BUSY, REJECT, 

and ACK packets for no good.


Both spacecraft will digipeat UI packets with the digipeater

path of WIDE.  See the downlink via K4HG's web page on:


http://pcsat.aprs.net <http://pcsat.aprs.net/>  


Of course, it would be best if any ARISS satgates QSY-ed

to 145.825 for the duration of this tes so that we get better 

reliability on packets getting to the WEB page above...


After 5 Feb, all it takes is ONE OVERLOAD in the

evening and it will Kill PCsat and we probably wont

get it back till next winter!  So PLEASE do not

overload her, and NO OPERAITONS AFTER DARK.


de Wb4APR, Bob
