[amsat-bb] Help with Icom Pre-Amps Needed

[Emily Clarke <w0eec@xxxxxxxxx>]

During Field Day I was getting a lot of HF interference through the Icom 
preamps (AG-25 and AG-35).  This was partially caused by the fact that the 
antennas were located underneath a large curtain of wire v-beams which may 
have been overloading the front end of the preamps.  This was happening a 
lot on 2m, less so on 70cm where I have a mode-J filter that probably 
reduced it.

So I decided that perhaps I could improve the shielding of the preamps and 
essentially put the preamps in some kind of Farraday shield.  Last Sunday 
afternoon I removed the four screws that attach the plastic rain cover so I 
could see what's inside.  Wouldn't budge.

Anyone have any suggestions?

73,

Emily
