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.
NO OPERATIONS AFTER DARK
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.
NO OPERATIONS AFTER DARK
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
