Hi Alexander,

Sorry I just missed you on AO51 - we will have to try again next time. 
Someone was covering you up pretty bad.

I have tried sending packets through the ISS with a stock rubber duck using 
my TH-D7A, and it is just about impossible.  I have found that you either 
need a mobile rig with a higher power output, or you need a higher gain 
antenna (Arrow, Elk).  Even with the Arrow I still have to try a few times 
to successfully send one through.  I am not sure how similar the TH-D72A is 
to the TH-D7A, but on the D7 a "My Packet" appears and blinks once you have 
been digipeated.  If you do not see this, you have probably not been

I have TH-D72A HT connected to a ANLI  AL-800 34" telescoping whip.
This morning there was an almost 90 degree pass over my grid square
(FN20rk).  I get loads of packets but for the life of me I can't
beacon myself!  :-(

I have my Decay Algorithm off, I have beaconing every 30 seconds (I
even manually beacon by pressing F+[Beacon] as per the Kenwood
manual).  I have my beaconing in APRS format.

Is this just not gonna happen on a HT?  I have tried 4 times with no
luck (all high elevation passes).  Again I see every packet that flies
by (comparing my HT list with that on ariss.net).  Very frustrating.
