Hi Tim and group

May I suggest that you get a hold on a preamp from SSB-electronics. I myself am using the SP-2000, and I'm happily satisfied with what it does. Wiring is as simple as can be. Power is fed over the coax-line and it can switch via rf-sensing up to about 200W, so if you don't run any big PA's then you should be going with just that.

However, I do not know enough about where to buy them outside europe, so can't help you on that one.

Hope you could use the information given.

Regards Martin, OZ1TMM

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?

Thanks,

Tim

Tim,

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
