I have attempted to check in to the SSET via PCSAT and have a couple of questions.
I receive stations through much of the pass, but I do not see my packets get returned. However, I have had two messages get to my email account, so it appears I have had some success.
Am I correct to expect that I can transmit a message then receive it on the same system during the same pass?
Also, I am using UISS and a soundcard. I received emails from APRS after sending the messages to "APRS via PCSAT-1". I have also tried "APRS via PCSAT-1, WIDE2-2". I have observed others using both paths. Is one path more correct?
Thank you, Kevin N2JPE

Yes, if your T/R turn around delay is not too bad. Right now, PCSAT has a TXD set to 12 or only 120 ms between hearing a packet and transmitting it. Most rigs should turn around that fast...

For the last wee, the only path that is set up now is via WIDEn-N. SO WIDE2-2 should work fine. All the other paths will not work now. This is because WIDEn-N has a built-in dupe ignore capability so those people who are trasnmitting too many dupes will get ignored for one minute after each success..

Although, we are still having some issues here in Europe as I have noticed that some stations are diging multi callsigns by with -1 -2 -3 prefixes! I still cannot hit PCSAT with my Kenwood TH-D7 on 5 watts using a 4 ele beam.. I have seen a Scottish station digi via FINDU,. but wonder if he is getting in before the footprint hits the mainland Europe.. I'll try again Friday..
All the best,
Chris
P.S. Can I just check for the D7 what the path should be! Just wide2-2?

Yes, problem is, there is no uplink discipline. Everyone just keeps hitting it harder and harder and over and over and hopes their packet will win. This is human nature, but it sure ruins the throughput and the ability of the little guy to get in.
P.S. Can I just check for the D7 what the path should be! Just wide2-2?
Yes, only WIDEn-N is now supported. Trying WIDE2-2 will get you a chance at a double hop throught PCSAT and/or ANDE or ISS. But not over europe. A double hop would be a miracle since one satellite would have to hear the other one in the middle of all that jamming...

It must be better over here in the United States. From Emeryville, CA I managed to get a couple of packets digipeated from PCSAT using only my TH-D7AG fed into the mag mount vertical (a short one at that) on top of my car. I was shocked that it actually worked with only 5w into an omni antenna. For this test I had a 2 minute beacon interval.
