Evening,

I've a dumb question.  A couple of them actually.  EI8JA and I were  
thinking of trying to help out, but we have no experience of  
satellite operation (other than an odd digi through pcsat or ISS).

He has a shiny new TS-2000 connected to a Diamond X510N
http://www.wsplc.com/acatalog/Diamond_VHF_UHF_Antennas.html mounted  
fairly high up at his home QTH.

I've got a Yaesu FT-847 and a soundmodem interface (I've not tested  
it yet at 9k6... I will after I send this email) connected to a X-300  
(same url as above).  I'm at one of the highest points around where I  
am and can see to the horizon from the southwest to just shy of due  
east.

I've got the TM-D700 in the car and a TH-D7 as well.

We have a Yaesu 736 connected to a X-300 and a 9K6 TNC in the college  
(Near EI8JA's QTH), but I've not got the levels right yet, its not  
receiving packets correctly.

Would anyone have any suggestions as to how we could make best use of  
this kit, with the highest likelihood for generating useful results?

Yours in experimentation,
de John
