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.

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?
