A manual for the PSK-1T will confirm its usage/connections.\n\nAs I remember, and W3IO probably has a better memory, PacComm introduced the PSK-1 for the PacSats launched at that time. \nLater, Gywn reintroduced the PSK-1T with some updates and suggested modifications. \nI first saw a PSK-1T at the 1995 AMSAT meeting in Orlando (1995) --- shown in preparation for AO-40.\n\n>> Greg -- You apparently outbid me for these items on eBay, assuming you recently obtained them ;-) ) \n>> I've been using it to command AO-16... I don't know about the DFM unit, other than I think it is\n>> probably 1200 and 9600 baud capable.\n\nMark, I was watching that eBay auction (# 320392587069), but did not bid on these items -- I already have one!\nThere were two PacComm PSK-1 and DFM TNC combinations for sale on QRZ a couple of weeks ago at $35 per set or $50 for both (great deal)!\nYes, the DFM permits usage at 9600 AFSK (which one of the satellites did support).\n\nGreg\nw9gb\n", "attachments": [] }
