I own SSB preamps, the SP-2000 (2 meter) and SP-7000 (70 cm).  They have worked very well for me, both on my Icom IC-821 (powered by the radio) and with my FUNcube Dongle (powered with an external bias-T from ARR).  The SSB preamps have helical filters on the front end which should help in your Los Angeles RF environment.

You have at least four sources for the SSB preamp:

1.  Direct from SSB in Germany, www.ssb.de 
2.  From SSB-Electronics USA, www.ssbusa.com 

3.  From Array Solutions, www.arraysolutions.com 

4.  From Universal Radio, www.universal-radio.com

Subject: [amsat-bb] Which preamp to buy for 2m?

Hi all,

I just got a M2 2M4 and 420-50-11 to mount on my az/el rotor and go with my 736R. As I'm hoping to potentially work some EME with the big guns when conditions are just right, I'm wondering if anyone can provide advice on which preamp to get for 2m. I live in the Los Angeles metro area, so lots of noise/QRM, and also would like something to take advantage of the 736's preamp switch/voltage over coax option. In other words, something that doesn't require any complicated power/switching controls, if possible. 


Any suggestions?
