[amsat-bb] HuskySat-1 transponder is open

[Mark Hammond]

HuskySat-1,435825,145925.0,USB,LSB,REV,0,0,XPDR 435.81-.84

Start there, Peter.  I have dropped the uplink on my IC-9700 (Leo Bodnar 
freq. stabilized) by like 200Hz or so, but rigs/etc will vary.   So my 
adjusted entry looks like

HuskySat-1,435824.8,145925.0,USB,LSB,REV,0,0,XPDR 435.81-.84

For all intents and purposes, it's right on frequency!  The Fox/Linear 
Transponder Module team did a super job with it.

HuskySat-1 demonstrates quite a bit of QSB, so if you can't hear 
yourself with like 5W or so, just be patient---it'll come back once the 
bird spins or tumbles a bit.  And remember, it's a weak signal bird!  
Don't expect to hear it with an HT and rubber duck!

73,

Mark N8MH (Command Team)
