I cannot find any fault with either unit. Both have \nworked FLAWLESSLY the entire time. Both have been out in the extremes of \ntemperature northern Vermont gets. Some slight discoloration from the \nsun of the housings. The 2 meter one is not quite so red any more, and \nthe 432 one a paler shade of blue, but that is all.\n\nThe ARR preamps are excellent as well, but limit you to 160 watts. For \nmost people running a typical satellite station, that would be fine. But \nif you also want to run V/UHF terrestrial, that may not be enough power \nhandling for you.\n\nWith a proper sequencer, the SP-2000 will handle 750 watts, and SP-7000 \nwill handle 500, and SSB offers a 1.5 kW 2 meter model for a real \nrockcrusher station.\n\nYou get what you pay for.\n\nSSB preamps are excellent in all respects for satellite work. I even \nmade my first ten 2 meter EME QSOs with the SP-2000.\n\nI had considered using one for my permanent two meter EME station as \nwell, but ended up using a receive only preamp and doing dual feedlines, \none for tx and one for rx.\n\n73, Bob W1ICW\n-- \n\nLight travels faster than the speed of sound, this is why some people tend to appear bright, until they decide to speak.\n\n", "attachments": [] }
